Apprentice Opportunities
The Department of Water Resources (DWR) paid apprenticeship program exams will be available June 24 to June 30 for those interested in applying for electrician, operator, mechanic, or utility craftsworker positions in California’s hydroelectric industry. Most apprenticeship positions have education requirements of equivalent to graduation from high school and knowledge of basic arithmetic and algebra, electrical fundamentals, and mechanical principles.
The online exams are currently posted on DWR’s CalCareers webpage with links to the individual exams for Hydroelectric Plant (HEP) Electrician Apprentice, HEP Mechanic Apprentice, HEP Operator Apprentice, and Utility Craftsworker Apprentice. Applying for more than one apprenticeship position is permitted but interested persons are reminded the online exams will only be available Friday, June 24 through Thursday, June 30. Passing applicants will be ranked and those with scores higher than 70 will be placed on the position’s eligible for hire list and can then apply for the apprenticeship program’s position openings. More information is available on the DWR Updates webpage.
DWR has eight hydroelectric powerplants in the State Water Project, three of which are in the Oroville-Thermalito Complex – Edward Hyatt Powerplant, Thermalito Diversion Dam Powerplant, and Ronald B. Robie Thermalito Pumping-Generating Plant.

FOURTH OF JULY FIREWORKS
The City of Oroville’s Noon Rotary Club fireworks will begin at approximately 9 p.m. on July Fourth and will be launched from the Oroville Airport. A Red Flag (severe fire danger) Warning from the National Weather Service for July Fourth will cancel the display. The morning at the airport will be filled with an airplane “fly-in”, pancake breakfast, car show, and airplane rides.
Viewers are encouraged to observe the fireworks show from their homes, if possible, or higher locations throughout the City of Oroville and surrounding area. The Clay Pit State Vehicular Recreation Area will close at sunset on Sunday, July 3 and remain closed until 8 a.m. Tuesday, July 5. The Nelson Avenue Sports Complex will be open but the pool will be closed. The Oroville Wildlife Area and Thermalito Afterbay will also maintain normal operating hours on July Fourth: 1.5 hours before sunrise to one hour after sunset. Information on morning activities at the airport, suggested viewing locations for the fireworks, and other event information is available on the Oroville Area Chamber of Commerce website.

WATER QUALITY WORKING GROUP
In November and December 2020, a multi-agency task force comprised of the State Water Resources Control Board and Central Valley Regional Water Quality Control Board; Butte County Department of Public Works; California Department of Water Resources; California Department of Fish and Wildlife; California Department of Parks and Recreation; and Governor’s Office of Emergency Services came together as the ‘Watershed Working Group’ to address water quality concerns in the North Complex Wildfire burn area and downstream. In 2021, the burn area of the Dixie Wildfire was added for monitoring, and additional partner agencies were added to the working group.
Widespread testing of surface waters throughout these burn scars in Butte and Plumas counties has been completed. Sampling results over the winter of 2021-22 revealed that while contaminant levels were slightly elevated in some instances, they did not exceed primary drinking water contaminant thresholds, and did not adversely impact drinking water treatment facilities or the quality of drinking water they deliver to their communities.
The working group’s agencies will now transition to routine water quality monitoring, which includes monitoring for issues such as Harmful Algal Blooms. Building on the success of the collaboration, this working group will continue to meet to discuss watershed health and be ready for the upcoming fire season. The public is reminded to always treat surface waters before drinking or cooking when recreating outdoors. Homeowners with wells in burn scar areas should review their well construction and consider contacting their county Environmental Health Division for information about testing well water.

BLUE GREEN ALGAE MONITORING
The Department of Water Resources (DWR) environmental scientists regularly monitor for blue-green algae and their toxins during the summer months. There are currently no harmful algal bloom (HAB) advisories for Lake Oroville, Upper Feather River lakes, the Thermalito Forebay, or the Thermalito Afterbay. Water samples are taken at various locations regularly from Memorial Day through Labor Day and sent to a lab for toxin analysis.
Blue-green algae (cyanobacteria) is a natural component of ecosystems. Under certain conditions, including warmer temperatures and increased nutrient loads, algae can grow rapidly causing “blooms.” Algal blooms sometimes produce toxins that can be harmful to people and animals. Algal blooms can make the water appear green, blue, or brown in color. Seeing colors, mats, foam, scum, or paint-like streaks in the water may indicate a bloom is present. Keep animals and children away from the water when a suspected HAB is present and report the possible HAB immediately.
If elevated levels of cyanobacteria toxins are found while testing, DWR staff will work with California’s Regional Water Quality Control Board and recreation area managers to notify the public and post advisory signs at affected waterbodies. To learn more about HABs, or to report a HAB visit the Water Board’s website.

OROVILLE RECREATION
The Lake Oroville State Recreation Area (LOSRA) is open for boating, camping, hiking, biking, horseback riding, and much more. The four main paved boat ramps at Lime Saddle, Bidwell Canyon, Spillway, and Loafer Point are open, along with the Lime Saddle and Bidwell Canyon marinas, and campground reservations can be made by visiting the CA Parks LOSRA website.
Restrooms, potable water, and fish cleaning stations are not in service at the Spillway Boat Ramp area but portable toilets are provided – please plan visits accordingly.
The Thermalito Forebays and Afterbay also provide a wide range of water recreation opportunities along with hiking trails, the Clay Pit State Vehicular Recreation area for Off-Highway Vehicles (OHVs) (south of Oroville Airport), and the 11,000 acres of prime wildlife viewing in the Oroville Wildlife Area. The OWA is administered for DWR by the CDFW and information about the 11,000-acre Oroville Wildlife Area is available on the CDFW webpage. The Forebay Aquatic Center in the North Forebay Recreation Area is open 10 a.m. to 8 p.m. Friday to Sunday with kayaks, paddle boards, and other watercraft available for rent. The Lake Oroville Visitor Center is open Tuesday through Thursday from 9 a.m. to 5 p.m.
An interactive map of recreation facilities in DWR’s Oroville-Thermalito Complex is available on DWR’s Lake Oroville Recreation webpage. Visitors are encouraged to be fire smart, bring plenty of sunscreen, stay hydrated, avoid leaving valuables in visible areas, be prepared for cold water temperatures, and be mindful of personal safety and the safety of those around you.

CURRENT LAKE OPERATIONS
The elevation of Oroville’s reservoir is about 761 feet elevation and storage is about 1.78 million acre-feet (MAF), which is 50 percent of its total capacity and 66 percent of historical average. Extreme heat above 100 degrees is expected to continue through the weekend and temperatures are forecasted to drop to the upper 90s next week.
The Feather River releases were increased last week and are currently at 3,500 cubic feet per second (cfs) to meet downstream Delta water quality and outflow needs. Currently, flows down the low flow channel will be ramping down beginning on Saturday and by Monday, flows through the City of Oroville are planned to be at 650 cfs with 2,850 cfs released from the Thermalito Afterbay Outlet (Outlet) for a total of 3,500 cfs downstream of the Outlet.
The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center at www.cdec.water.ca.gov. The Lake Oroville gage station is identified as “ORO”.
All data as of midnight 6/23/2022

California is entering its third year of drought conditions. With water conservation now a way of life in California, everyone is encouraged to find ways to save water. See tips, tools, and ideas on the Save Our Water website.

Protecting Against Quagga and Zebra Mussels
As boating season kicks off, The Department of Water Resources (DWR), California State Parks’ Division of Boating and Waterways (DBW), and California Department of Fish and Wildlife (CDFW) urge boaters to always remember to clean, drain, and dry their boats before entering and leaving lakes, rivers, and other waterways to help prevent the spread of quagga or zebra mussels.
These two non-native freshwater mollusks – quagga and zebra mussels – pose a serious threat to California’s aquatic ecosystems. Quagga and zebra mussels are small, invasive species that colonize on hard surfaces, such as boat hulls and pontoons, docks and pilings, rocks, concrete, plastics, and even discarded bottles and cans. DWR’s Oroville Field Division biologists regularly sample Lake Oroville -for indicators the mollusks are present and, to date, none have been found.
Quagga and zebra mussels can be spread to new waterbodies when attached to boats as adults, or as microscopic juveniles in water in motors, bilges, and livewells. They are smaller than a dime, and juvenile mussels may even be difficult to detect with the naked eye. Despite their small size, they can cause major damage to water delivery systems, hydroelectric facilities, and watercraft engines.
When boating, make it a habit to do the following:

Remove all plants and animal material from your boat, trailer, and equipment
Wash the hull of your boat or other watercraft thoroughly, preferably with high-pressure hot water
Clean your gear before entering and leaving the recreation area
Drain bilge, ballast, wells, and buckets before you leave the area
Inspect all exposed surfaces -- small mussels feel like sandpaper to the touch
Dry equipment before launching into another body of water
Allow at least a seven to eight day dry-out period before entering another body of water

Report any mussels you find to the local marina and the CDFW hotline at (866) 440-9530.

SOUTH FOREBAY CLOSED
The California Department of Parks and Recreation (CA Parks) announced today the South Forebay and the Nelson Bridge Day Use Area will be closed from 8 a.m. Saturday, June 11 to 8 a.m. Monday, June 13 for a private boat racing event. Entrances to the South Forebay at Grand Avenue, Nelson Avenue Bridge Day Use Area and behind Poplar Avenue Elementary School will be closed, including the levee system to the east and south of the forebay. CA Parks has closed these areas to public use, entry, or occupancy.

CAL FIRE CONTROL BURNS
In cooperation with DWR and CA Parks, CAL FIRE conducted control burns around the North Forebay, the Nelson Sports Complex, and along Grand Avenue this past week. The vegetation management-control burns have multiple beneficial impacts for the natural environment and public safety.
Around the Thermalito Forebay are many seasonal wetlands called vernal pools which support a high diversity of California native plants and animals, including rare and endangered species and species endemic to California (i.e., found nowhere else in the world). Fire from carefully controlled burns is the most powerful tool to combat invasive plants and dry invasive grass buildup called ‘thatch’ within these grasslands and vernal pools, as well as from grassland adjacent to private property and near high-use areas.
Additional plots may be burned over the next two weeks at Loafer Creek Recreation Area as weather conditions allow. Smoke will be visible at times in the Kelly Ridge and Greater Oroville areas throughout the duration of the project.

OROVILLE RECREATION
The Lake Oroville State Recreation Area (LOSRA) is open for boating, camping, hiking, biking, horseback riding, and much more. The four main paved boat ramps at Lime Saddle, Bidwell Canyon, Spillway, and Loafer Point are open, along with the Lime Saddle and Bidwell Canyon marinas, and campground reservations can be made by visiting the CA Parks LOSRA website.
Restrooms, potable water, and fish cleaning stations are not in service at the Spillway Boat Ramp area but portable toilets are provided – please plan visits accordingly.
The Thermalito Forebays and Afterbay also provide a wide range of water recreation opportunities along with hiking trails, the Clay Pit State Vehicular Recreation area for Off-Highway Vehicles (OHVs) (south of Oroville Airport), and the 11,000 acres of prime wildlife viewing in the Oroville Wildlife Area. The OWA is administered for DWR by the CDFW and information about the 11,000-acre Oroville Wildlife Area is available on the CDFW webpage. The Forebay Aquatic Center in the North Forebay Recreation Area is open 10 a.m. to 8 p.m. Friday to Sunday with kayaks, paddle boards, and other watercraft available for rent.
An interactive map of recreation facilities in DWR’s Oroville-Thermalito Complex is available on DWR’s Lake Oroville Recreation webpage. Visitors are encouraged to be fire smart, bring plenty of sunscreen, stay hydrated, avoid leaving valuables in visible areas, be prepared for cold water temperatures, and be mindful of personal safety and the safety of those around you.

GRAZING EFFORTS REDUCE FIRE RISK
More than 100 goats and sheep continue to provide vegetation management along Canyon Drive from Royal Oaks Drive to Oroville Dam’s Upper Overlook Parking Area as part of DWR’s Fuel Load Management Plan to reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville.
To increase the amount of vegetation removed, a mixture of goats and sheep are used by contractor Hanski Family Farms because the animals prefer different vegetation types. Goats prefer ladder fuels (shrubs, bushes, smaller trees, or tree branches near the ground) and sheep prefer grasses. When goats stand on their hind legs, they can reduce ladder fuels up to six feet high.
DWR, in partnership with Butte County Fire Safe Council, continues to use grazing as a sustainable method of fuel reduction around DWR’s Oroville-Thermalito Complex, including Lake Oroville.

CURRENT LAKE OPERATIONS
The elevation of Oroville’s reservoir is about 770 feet elevation and storage is about 1.87 million acre-feet (MAF), which is 53 percent of its total capacity and 68 percent of historical average. The forecast calls for a chance of rain over the weekend with dry conditions next week. Temperatures are forecasted to be in the low-100s on Saturday and will be dropping beginning on Sunday into next week. Temperatures are expected to fluctuate from the low-80s-to-mid-90s through the week.
The Feather River releases were increased last week and are currently at 3,500 cubic feet per second (cfs) to meet downstream Delta water quality and outflow needs. Currently, flows down the low flow channel through the City of Oroville have increased to 1,450 cfs and 2,050 cfs is being released from the Thermalito Afterbay Outlet (Outlet) for a total of 3,500 cfs downstream of the Outlet. Flows are assessed daily and may fluctuate through the low flow channel for fisheries purposes during the week.
The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center at www.cdec.water.ca.gov. The Lake Oroville gage station is identified as “ORO”.

CAL FIRE Control Burns
In cooperation with the Department of Water Resources (DWR) and California Department of Parks and Recreation (CA Parks), CAL FIRE conducted control burns of around 185 acres this past week at South Forebay near Grand Avenue (~65 acres), near Wilbur Road and Tres Vias Road (~120 acres), and at the Loafer Creek Recreation Area (~55 acres). The vegetation management-control burns have multiple beneficial impacts for the natural environment and public safety.
Around the Thermalito Forebay are many seasonal wetlands called vernal pools which support a high diversity of California native plants and animals, including rare and endangered species and species endemic to California (i.e., found nowhere else in the world). Fire from carefully controlled burns is the most powerful tool to combat invasive plants and dry invasive grass buildup called ‘thatch’ within these grasslands and vernal pools, as well as from grassland adjacent to private property and near high-use areas.
The control burn at Loafer Creek Recreation Area removed fuels such as brush and dry grasses from several plots totaling around 55 acres. Prescribed fires, when conducted on a regular basis, help to reduce the risk of catastrophic wildfires on area landscapes and surrounding communities by reducing the amount of fire hazardous vegetation. Previous CAL FIRE prescribed fires, and vegetation management reduction work in the Loafer Creek area done through DWR’s Fuel Load Management Program, as credited with slowing the North Complex Fire in 2020 enough for firefighters to gain the upper hand, establish a successful fire line, and prevent further forward progression of the fire.
Additional plots may be burned over the next two weeks at Loafer Creek as weather conditions allow. Smoke will be visible at times in the Kelly Ridge and Greater Oroville areas throughout the duration of the project.

OROVILLE RECREATION
With Memorial Day – the unofficial start of summer – just behind us, DWR invites the public to take advantage of the many recreation opportunities at the State Water Project’s Oroville Thermalito Complex.
Lake Oroville: The Spillway, Loafer Point, Bidwell Canyon, and Lime Saddle boat ramps are open 24-hours, seven days a week and car-top boat ramps are open from 8 a.m. to sunset. Both the Lime Saddle and Bidwell Canyon Marinas are open and provide boat rentals. Restrooms, potable water, and fish cleaning stations are not in service at the Spillway Boat Ramp area but portable toilets are provided – please plan visits accordingly.
Thermalito Forebays and Afterbay: Visitors to the Thermalito North Forebay will find a full California Department of Parks and Recreation (CA Parks) facility with restrooms, picnic areas, a swim beach, and the Forebay Aquatic Center with kayaks, paddle boards, and other watercraft available for rent. Power boating is not allowed on the North Forebay but is permitted on the Thermalito South Forebay where the boat ramp area has a sandy beach, picnic tables, shade trees and vault toilets (no drinking water is available).
The Monument Hill and Wilbur Road boat ramp areas on the Thermalito Afterbay are open as well as the Larkin Road car-top boat ramp. The Monument Hill facility provides boat ramp access, restrooms, a picnic area, and a swim beach. The Wilbur Road boat ramp has boat launch lanes and a vault toilet. Boaters on the Afterbay are reminded of the 5-mph speed limit north of the Highway 162 bridge and that access to the Afterbay is from 1.5 hours before sunrise to one hour after sunset.
Oroville Wildlife Area: Primarily a primitive wildlife area managed for fishing, wildlife viewing and hunting, the Oroville Wildlife Area (OWA) is accessed primarily by boat on the Feather River, by area trails, or from developed and primitive roads off Highway 162, Highway 70, and Larkin Road. The Clay Pit State Vehicular Recreation area for Off-Highway Vehicles (OHVs), a CA Parks facility, is located south of the Oroville Airport and the clay used to build the core of Oroville Dam was excavated from this area. The OWA is administered for DWR by the California Department of Fish and Wildlife (CDFW) and information about the 11,000-acre Oroville Wildlife Area is available on the CDFW webpage.
Lake Oroville Visitor Center and Area Trails: The Visitor Center is open to the public on Tuesdays, Wednesdays, and Thursdays from 9 a.m. to 5 p.m. where visitors can view educational exhibits, walk area trails, and climb the 47-foot-tall viewing tower. The Lake Oroville Trails Map, which shows more than 91 miles of trails available to equestrians, bicyclists, and hikers all around the facilities mentioned above, is available at the Visitor Center, at Lake Oroville State Recreation Area (LOSRA) kiosks, the Oroville Area Chamber of Commerce, or at the Feather River Recreation and Parks office.
An interactive map of recreation facilities in DWR’s Oroville-Thermalito Complex is available on DWR’s Lake Oroville Recreation webpage at https://water.ca.gov/What-We-Do/Recreation/Lake-Oroville-Recreation. Visitors are encouraged to be fire smart, bring plenty of sunscreen, stay hydrated, avoid leaving valuables in visible areas, and be mindful of personal safety and the safety of those around you.

COLD WEATHER ALERT
With the Memorial Day holiday and warm weather starting the summer months, DWR reminds those recreating in area lakes and rivers that waters are still very cold. The Feather River below Oroville Dam is around 55 to 60 degrees. While surface temperatures of Lake Oroville can be warmer, colder water is present only a few feet below the surface. Additionally, inflows from snowmelt are feeding the upper reaches of the Feather River’s forks where cold water shock can impair breathing and heart rate after a sudden immersion.
Outdoor enthusiasts are encouraged to be mindful of water temperatures and wear a life jacket if near or on the water. For more information, visit the National Weather Service’s Safety webpage.

PLUMAS NATIONAL FOREST
Several recreation sites on the Plumas National Forest have opened, including on DWR’s Upper Feather Lakes of Lake Davis, Frenchman Lake, and Antelope Lake. Recreation facilities such as day use areas, beaches, and campgrounds, are managed by the U.S. Forest Service and their contractors. For information about recreation facility locations, amenities, and current conditions and restrictions, visit the Plumas National Forest webpage.

GRAZING EFFORTS REDUCE FIRE RISK
Drivers along Canyon Drive from Royal Oaks Drive to Oroville Dam’s Upper Overlook Parking Area will see how grazing is used in DWR’s Fuel Load Management Plan to reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville. For the next couple of weeks, goats and sheep will be visible along the hillside adjacent to the roadway.
To increase the amount of vegetation removed, a mixture of goats and sheep are used by contractor Hanski Family Farms because the animals prefer different vegetation types. Goats prefer ladder fuels (shrubs, bushes, smaller trees, or tree branches near the ground) and sheep prefer grasses. When goats stand on their hind legs, they can reduce ladder fuels up to six feet high.
DWR, in partnership with Butte County Fire Safe Council, continues to use grazing as a sustainable method of fuel reduction around DWR’s Oroville-Thermalito Complex, including Lake Oroville. To learn more, visit DWRs YouTube Channel for a video of the March 2021 Lakeland Boulevard goat grazing project.

CURRENT LAKE OPERATIONS
The elevation of Oroville’s reservoir is about 772 feet elevation and storage is about 1.9 million acre-feet (MAF), which is 54 percent of its total capacity and 68 percent of historical average. The forecast calls for a chance of rain over the weekend with dry conditions next week. Temperatures are expected to be in the mid-to-upper-70s over the weekend and increasing to the mid-90s by the middle of the week.
The Feather River releases were increased last week and are currently at 3,000 cubic feet per second (cfs) to meet downstream Delta water quality and outflow needs. Flow in the low-flow channel through the City of Oroville is 650 cfs and flow through the Thermalito Afterbay Outlet is currently 2,350 cfs. Flows are assessed daily.

Visitors are encouraged to be fire smart, bring plenty of sunscreen, stay hydrated, avoid leaving valuables in visible areas, and be mindful of personal safety and the safety of those around you.

THERMALITO FOREBAY CONTROL BURNS
A series of vegetation management burns around the Thermalito Forebay were conducted by CAL FIRE/Butte County Fire Department on May 27 in cooperation with the Department of Water Resources (DWR) and CA Parks. A total of about 60 acres near the Forebay Aquatic Center (~20 acres) and west of the Nelson Sports Complex (~40 acres) were successfully treated along with 30 acres of grassland at the Rabe Road Shooting Range south of Oroville Airport. An additional treatment of 185 acres is planned for the week of May 30 at South Forebay near Grand Avenue (~65 acres), and near Wilbur Road and Tres Vias Road (~120 acres).
The vegetation management-controlled burns have multiple benefits for the natural environment and public safety. The grasslands around the Thermalito Forebay are home to many seasonal wetlands called vernal pools. Although vernal pools are only a small component of these grasslands, they support a high diversity of California native plants and animals, including rare and endangered species and species endemic to California (i.e., found nowhere else in the world).
Fire from carefully controlled burns is the most powerful tool to combat invasive plants and dry invasive grass buildup called ‘thatch’ within these grasslands and vernal pools. Removal of invasive species allows native plants and animal species, such as fairy shrimp, to thrive. The burns will also remove dangerous fire fuels from grassland adjacent to private property and near high-use areas. CAL FIRE Battalion Chief Jason Dyer also noted that the projects allow firefighters to practice skills in a controlled environment.

CURRENT LAKE OPERATIONS
The elevation of Oroville’s reservoir is about 776 feet elevation and storage is about 1.9 million acre-feet (MAF), which is 54 percent of its total capacity and 69 percent of historical average. Expect dry and temperatures in the mid-70s to 80s this weekend, increasing to the low- to mid-90s next week.
The Feather River releases were increased last week and are currently at 2,700 cubic feet per second (cfs) to meet downstream Delta water quality and outflow needs. Flow in the low-flow channel through the City of Oroville is 650 cfs and flow through the Thermalito Afterbay Outlet is currently 2,050 cfs. Flows are assessed daily.

Inland Salmon Released into Lake Oroville
California Department of Fish and Wildlife (CDFW) staff from the Feather River Fish Hatchery released 129,200 triploid fall-run “inland” Chinook fingerling salmon into Lake Oroville on May 12 at the Loafer Point Stage II Boat Ramp to support the recreational fishery. Of the 129,200 fish planted, 110,200 were direct release from the boat ramp and 19,000 fish were released into the main body of Lake Oroville from boats equipped with well holding tanks.
This is the first year the fish were released into the main body of the lake to diversify and increase fishing opportunities. The inland Chinook measured about four to five inches in length and were raised at the Feather River Fish Hatchery. The fish are triploid, meaning unable to reproduce, which allows them to grow larger in size instead of putting energy into reproducing and it prevents any of these fish escaping Lake Oroville from hybridizing with sensitive downstream Chinook salmon populations.
The Department of Water Resources (DWR) built, maintains, and funds the Feather River Fish Hatchery in partnership with CDFW staff who conduct fish spawning, rearing, and stocking activities at the hatchery. The Hatchery’s fish planting program has been in operation since 1968. A virtual tour of the Hatchery can be viewed on DWR’s YouTube channel and additional information can be found on the CDFW website.

GRAZING EFFORTS REDUCE FIRE RISK
Drivers traveling Oroville Dam Boulevard East below Oroville Dam have been treated to views of hundreds of goats and sheep grazing on nearly 35 acres along the Brad Freeman Trail, Hyatt Powerplant, and the Lower Overlook. Next week they will be moved to Canyon Drive where they will be grazing for the next couple of weeks along the hillside from Royal Oaks Drive to the Upper Overlook Parking Area.
To increase the amount of vegetation removed, a mixture of goats and sheep are used by contractor Hanski Family Farms because the animals prefer different vegetation types. Goats prefer ladder fuels (shrubs, bushes, smaller trees, or tree branches near the ground) and sheep prefer grasses. When goats stand on their hind legs, they can reduce ladder fuels up to six feet high.
The grazing project is part of DWR’s Fuel Load Management Plan, which helps reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville. In partnership with Butte County Fire Safe Council, DWR continues to use grazing as a sustainable method of fuel reduction around DWR’s Oroville-Thermalito Complex, including Lake Oroville.
To learn more and to see goat grazing in action, visit DWRs YouTube Channel for a video of the March 2021 Lakeland Boulevard goat grazing project on DWR’s YouTube webpage.

DROUGHT UPDATE
Warming temperatures, along with the driest January through March on record, has left the statewide snowpack at 14 percent of average for this date despite the recent late season storms. The main benefit of late season storms will be to prevent soils from drying out early in the season, which can aid runoff efficiency of the remaining snowpack to the state’s reservoirs.
Reservoir levels across California vary depending on their location and source of inflows but all are reflective of the state entering its third year of drought. Locally, record-setting precipitation from the late October 2021 atmospheric river (AR) storm fell mainly in the Feather River (Oroville Dam) and American River (Folsom Dam) watersheds, missing a large part of the Lake Shasta watershed. Lake Oroville currently has more storage than on this date last year and the Department of Water Resources (DWR) is working to preserve as much storage as possible for future needs to maintain Delta water quality, protect endangered species, and meet senior water right obligations.
DWR is also administering a number of grant programs to help mitigate and address drought impacts. One program, the Small Community Drought Relief Program, has already awarded more than $33 million to local counties and cities around Oroville for projects such as water system improvements and connections in Orland, Berry Creek, and Williams and for water hauling in Butte, Glenn, and Colusa counties.
The DWR hydrology team and a California Water Board data specialist held a media briefing with reporters and meteorologists May 10 to discuss the latest drought data points and where we stand in terms of current conditions. A recording of the briefing is available on the DWR YouTube webpage.
As we enter the warmer months, everyone is encouraged to find ways to save water, because despite current reservoir levels, the state is going to have water challenges later this year. See tips, tools, and ideas on the Save Our Water website. Information about real time local hydrological conditions, forecasts, and water conditions is available on DWR’s new website California Water Watch. Visit DWR’s Drought webpage for the latest information.

Drought Update
California has experienced the driest January through March on record, leaving the statewide snowpack at 23 percent of average for this date despite the recent late season storms. The main benefit of late season storms will be to prevent soils from drying out early in the season, which can aid runoff efficiency of the remaining snowpack to the state’s reservoirs.
Reservoir levels across California vary depending on their location and source of inflows but all are reflective of the state entering its third year of drought. Locally, record-setting precipitation from the late October 2021 atmospheric river (AR) storm fell mainly in the Feather River (Oroville Dam) and American River (Folsom Dam) watersheds, missing a large part of the Lake Shasta watershed. Lake Oroville currently has more storage than on this date last year and the Department of Water Resources (DWR) is working to preserve as much storage as possible for future needs to maintain Delta water quality, protect endangered species, and meet senior water right obligations.
DWR is also administering a number of grant programs to help mitigate and address drought impacts. One program, the Small Community Drought Relief Program, has already awarded more than $33 million to local counties and cities around Oroville for projects such as water system improvements and connections in Orland, Berry Creek, and Williams and for water hauling in Butte, Glenn, and Colusa counties.
The DWR hydrology team and a California Water Board data specialist held a media briefing with reporters and meteorologists Tuesday to discuss the latest drought data points and where we stand in terms of current conditions. A recording of the briefing is available on the DWR YouTube webpage.
As we enter the warmer months, everyone is encouraged to find ways to save water, because despite current reservoir levels, the state is going to have water challenges later this year. See tips, tools, and ideas on the Save Our Water website. Information about real time local hydrological conditions, forecasts, and water conditions is available on DWR’s new website California Water Watch. Visit DWR’s Drought webpage for the latest information.

COLLABORATING TO SUPPORT SALMON
Managing California's water needs during our severe drought means minimizing impacts on our environment while also meeting the health and safety, economic, and agriculture needs of our communities. The Department of Water Resources (DWR) and Department of Fish and Wildlife (CDFW) are actively working to respond to drought and climate change impacts posing challenges to our native species and ecosystems, including California’s salmon populations.
Scientists and fish biologists from both DWR and CDFW have a long history of working together and collaborating with federal, state, local, non-governmental, tribal, and academic partners who have joined forces to protect and support California’s salmon populations. Collaborating through shared projects, funding, and research efforts, DWR and CDFW are identifying critical challenges facing salmon and using the best available science and technology to find ways to promote salmon health and survival.
The state has embarked on dozens of projects to ensure the success of California’s salmon population. Some of these projects are highlighted in the recent DWR-CDFW news release. These projects include restoring critical habitat for salmon and other fish species, improving salmon migration corridors to and from the ocean, and increasing our monitoring efforts so we can better track the status of populations and devise new strategies to improve their status. View the latest video on the DWR YouTube channel.
To learn more about collaborative projects protecting our salmon populations, check out the DWR website highlighting these efforts and more. Additional projects will be featured throughout the summer.

WILDFIRE PREPAREDNESS WEEK RECAP
California Governor Gavin Newsom recently proclaimed May 1 to May 7, 2022, as “Wildfire Preparedness Week”. With California experiencing some of the largest and most destructive fires over the last few years and lingering drought conditions leaving fuel moisture levels very low, the state is taking action to help make communities more resilient to wildfire and improve forest health. “I urge all Californians to take lifesaving steps to stay prepared, including making their homes more fire-resistant, creating defensible space, and developing a wildfire action plan well ahead of time” Governor Newsom said.
CAL FIRE kicked off the week with educational events across the state to raise awareness on wildfire preparedness, including how state, federal, and local public safety organizations are preparing for the 2022 fire season. CAL FIRE stresses the importance of fuel reduction and vegetation management projects and ways the public can prepare for wildfire through making your home more fire resistant (home hardening), creating defensible space, and developing a wildfire action plan well ahead of time.
DWR continues to prepare for wildfire around the Oroville-Thermalito Complex by implementing fuel reduction projects and creating defensible space around infrastructure and adjacent to residential communities. Through the use of grazing, brush removal, chipping, and controlled burns DWR with area partners including CAL FIRE, California Department of Parks and Recreation (CA Parks), Butte County Fire Safe Council (BCFSC) aim to reduce wildfire risk, increase public safety, and promote forest health. Currently, DWR in partnership with BCFSC and goats from Hanski Family Farms are grazing 35 acres along Oro Dam Blvd. East with the goal of reducing ladder fuels to help lessen the spread of a potential wildfire, protecting infrastructure and nearby communities.
Californians are encouraged to join these wildfire preparedness efforts by taking actions now to protect your home and family. Develop your personalized plan by visiting https://plan.readyforwildfire.org/.

OROVILLE RECREATION ADVISORY COMMITTEE
The Oroville Recreation Advisory Committee met today, May 6 at the Southside Community Center in Oroville. ORAC was established by the Federal Energy Regulatory Commission (FERC) to review and provide recommendations regarding DWR’s recreation plan for the Project No. 2100 – Oroville Facilities. The 13-member committee is made up of representatives from state and local government, sports and recreation groups, and business and community organizations. To obtain a summary of the meeting, send a request to oroville@water.ca.gov.

MAPPING STATE’S GROUNDWATER BASINS
DWR is conducting an innovative, helicopter-based technology of airborne electromagnetic (AEM) surveys to gather information about the state’s groundwater aquifer structure to support drought response and the implementation of the Sustainable Groundwater Management Act (SGMA). The AEM surveys are scheduled in groundwater basins within portions of Colusa, Butte, Glenn, Tehama, and Shasta counties during May.
Survey data creates an image of the subsurface down to a depth of about 1,000 feet below ground surface and provides information about large-scale aquifer structures and geology. This information supports the implementation of local groundwater sustainability plans (GSPs), which can help local agencies sustainably manage groundwater during drought. DWR has a short 2-minute video about the AEM method, provided in both English and Spanish, as well as an AEM project website.
DWR encourages residents to get involved in their local groundwater management activities and GSP implementation through your groundwater sustainability agency (GSA). Information about local GSAs can be found on the SGMA portal.

LAKESIDE ACCESS ROAD OPENS
Visitors to the Spillway Boat Ramp and Day Use Area and nearby trails are now using the newly constructed Lakeside Access Road. The new, more direct road, which can be used when lake elevations are below 800 feet, begins from the Oroville Dam Crest Parking lot at the northwest of Oroville Dam.
The new road descends into the lake inundation zone before travelling back up to the Spillway Boat Ramp parking lot. The previous access road through the CHP screening booths and below the Emergency Spillway will only need to be used when lake elevations rise high enough to flood the new Lakeside Access Road. Visitors are cautioned to be alert for continuing construction activities and to follow signage.

DWR Partners with California Rice Commission
The Department of Water Resources (DWR) has provided $8 million dollars to the California Rice Commission’s ‘California Ricelands Waterbird Foundation’ to help increase the amount of available flooded habitat for migratory birds making their journey along the Pacific Flyway this year. Current drought conditions have reduced summer flooding of semi-permanent wetlands in the Sacramento Valley, reducing essential resources for breeding waterfowl, shorebirds, and other wetland-dependent species that are severely impacted by the drought.
This past winter and through the spring, DWR supported a collaboration of multiple partners, including Audubon California, Ducks Unlimited, The Nature Conservancy, California Department of Fish and Wildlife (CDFW) and others, to create nearly 55,000 acres of flooded waterbird habitat on rice fields and private wetlands by providing incentive payments to wetland owners to flood (or hold water from winter flooding) their wetlands to a depth of 12 to 24 inches beginning April 1, 2022 until July 15, 2022. After July 15, wetland managers will rely on evaporation (vs. draining) to draw down flooded fields, extending vital habitat for migrating shorebirds who prefer shallow waters.
As the DWR manages California’s water needs during this water supply crisis, actions and projects like this one to minimize the impacts of drought and water management on our environment (while still meeting the needs of our communities’ health and safety, our economy, and agriculture), will significantly benefit wildfowl migrating up and down the Western United States as well as those who live in the Valley year-round.

Flood Safety Stakeholder Technical Workshop
The Oroville Dam Citizens Advisory Commission held a virtual Flood Safety Stakeholder Technical Workshop on April 22 to allow the California Natural Resources Agency (CNRA), DWR, and other government officials hear directly from and speak directly to community stakeholders about their goals, interests and concerns related to flood safety and downstream communities. Presentations on extreme precipitation, managing floods, forecasting, and how dams, channels, floodplains, burn scars, and adequate preparations impact flooding and response were provided. Stakeholders and public participants asked questions and offered comments. The meeting transcript and presentations will be available on the Commission’s website in the coming weeks https://bit.ly/OrovilleCAC.

GRAZING GOATS REDUCE FIRE RISK
Hillsides along the Dan Beebe trail near Hyatt Powerplant and Oroville Dam’s Lower Overlook are looking different as 600 goats and sheep from the Hanski Family Farms are visiting the area. The goal for this grazing effort is to minimize the rate of spread of a potential fire by reducing ground fuels, ladder fuels, and overgrown vegetation on approximately 35 acres near Oro Dam Boulevard East.
Grazing is gaining popularity across California as a sustainable method to minimize wildfire risk and lessen the spread of a wildfire through vegetation management. The goats and sheep near Hyatt Powerplant will graze on grasses, leaves, poison oak, and a variety of shrubs and trees. By standing on their hind legs, they can reduce ladder fuels up to six feet high. Plus, they love to eat weeds, especially invasive ones.
The goat grazing project is part of DWR’s Fuel Load Management Plan, which helps reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville within the Federal Energy Regulatory Commission (FERC) project boundary. In partnership with Butte County Fire Safe Council, DWR continues to use grazing as a sustainable method of fuel reduction around DWR’s Oroville-Thermalito Complex.

Feather River Fish Hatchery Opens
All but one of the California Department of Fish and Wildlife (CDFW) fish hatcheries are open. The hatcheries have been closed for nearly two years during the COVID-19 pandemic. The main Feather River Fish Hatchery facility in Oroville is now open from 7:30 a.m. to 4 p.m. seven days a week. The viewing window and overlook side will continue to be open sunrise to sunset.
Learn how the hatchery raises Chinook salmon and steelhead to support California’s salmon populations during your visit. Interpretive panels describing the salmon life cycle, hatchery operations, and more are available for visitors. A virtual tour of the hatchery is also available on the Department of Water Resources (DWR) YouTube channel. Guided tours of the hatchery will resume when the fall-run Chinook salmon return to the river later this year.
The Feather River Fish Hatchery (FRFH) is divided into 2 sections:

The first section (viewing window side) includes the fish barrier dam, observation platform, and underwater viewing window, located on the east side of Table Mountain Boulevard. The underwater viewing windows are best for viewing fish from mid-September through June. This side of the facility is open daily from sunrise to sunset.
The second section (main facility) includes the spawning room, hatchery, and rearing ponds located on the west side of Table Mountain Boulevard. Salmon spawning operations can be observed Monday through Friday beginning mid-September until mid-November. Steelhead spawning can be observed mid-December through mid-February. Fish are present in the rearing ponds year-round. This side of the facility is open from 7:30 a.m. to 4 p.m. daily.

Over 8 million spring-run and fall-run Chinook salmon are produced by the hatchery annually, along with nearly 450,000 steelhead who are returned to the Feather River or planted in the Thermalito Afterbay for recreational users. To mitigate impacts from this third year of drought conditions, the facility will be raising an additional 1.7 million fall-run Chinook salmon to support the Feather River population. An additional 125,000 Inland Chinook will be planted in Lake Oroville this spring.
The Feather River Fish Hatchery is a California State Water Project facility owned and maintained by DWR, which funds hatchery operations. CDFW operates the hatchery, including fish spawning, rearing, and stocking activities. DWR built the fish hatchery to mitigate the impact of the Oroville Dam on Chinook salmon and steelhead populations because the dam blocks access to natural spawning grounds further upstream.

Oroville Recreation
The Loafer Point, Bidwell Canyon, and Lime Saddle boat ramps are open. The Oroville Dam Spillway boat ramp remains closed for repairs. The Foreman Creek and Stringtown cartop boat ramps are also open.
Information on current boat ramp status can be found on the California State Parks’ Lake Oroville State Recreation Area webpage. Scroll down to the link for “Current Launch Ramp Status”.

SNOWPACK SURVEY
The Department of Water Resources (DWR) conducted the fourth snow survey of the season April 1 at Phillips Station near Echo Summit. Following a January, February, and March that will enter records as the driest documented in state history, the manual survey recorded 2.5 inches of snow depth and a snow water equivalent of 1 inch, which is 4 percent of average for this location for April.
The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. Statewide, the snowpack was 38 percent of average for the April 1 date. (One week later, due to high temperatures causing more snowmelt, the statewide average was at 27 percent.)
“The conditions we are seeing today speak to how severe our drought remains. DWR has been planning for the reality of a third dry year since the start of the water year on October 1,” said DWR Director Karla Nemeth. “While DWR has made significant investments in forecasting technology and other tools to ensure we make the most out of the snowmelt we do receive, water conservation will remain our best tool in the face of this ongoing drought and the statewide impacts of a warming climate. All Californians must focus on conserving water now.” The full snow survey news release can be found on the DWR News page.
Governor Gavin Newsom has asked all Californians to cut back water use at least 15 percent compared to 2020 levels. Current water conditions are now available in real time at California Water Watch, a new website launched by DWR. The website will help Californians see their local hydrological conditions, forecasts, and water conditions down to their address or their local watershed. Additional tips on how to conserve can be found at the SaveOurWater webpage.

Snowpack Survey
The Department of Water Resources (DWR) conducted the fourth snow survey of the season Friday at Phillips Station near Echo Summit. Following a January, February, and March that will enter records as the driest documented in state history, the manual survey recorded 2.5 inches of snow depth and a snow water equivalent of 1 inch, which is 4 percent of average for this location for April.
The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. Statewide, the snowpack is 38 percent of average for this date.
“The conditions we are seeing today speak to how severe our drought remains. DWR has been planning for the reality of a third dry year since the start of the water year on October 1,” said DWR Director Karla Nemeth. “While DWR has made significant investments in forecasting technology and other tools to ensure we make the most out of the snowmelt we do receive, water conservation will remain our best tool in the face of this ongoing drought and the statewide impacts of a warming climate. All Californians must focus on conserving water now.” The full snow survey news release can be found on the DWR News page.
Governor Gavin Newsom has asked all Californians to cut back water use at least 15 percent compared to 2020 levels. Current water conditions are now available in real time at California Water Watch, a new website launched by DWR. The website will help Californians see their local hydrological conditions, forecasts, and water conditions down to their address or their local watershed. Additional tips on how to conserve can be found at the SaveOurWater webpage.

Boat Ramp Closures
A speed boat timed trial event on the Thermalito Afterbay is scheduled for April 1 to April 3. The event requires the southern portion of the Afterbay (south of Highway 162) to be closed to the public April 2 and April 3. Both the Monument Hill boat ramp and Larkin Cartop boat launch will be closed. The Wilbur Road boat ramp and areas north of Hwy 162 will remain open.
Returning to the Afterbay after two years away due to the COVID-19 pandemic, the 59th Annual Region 9 Bud David Time Trials event is anticipated to draw 40 to 50 boats. Information about the event can be found on the American Power Boat Association webpage at https://www.apba.org/racing-schedule.html
The Loafer Point boat launch area will be closed Monday, April 4 for installation of a gate. Boaters are encouraged to use the Bidwell Canyon boat ramp as an alternate launch site on that day.

DWR Announces Revised Water AllocationLast week, DWR announced it must reduce the State Water Project allocation to 5 percent of requested supplies for 2022. DWR previously set the allocation at 15 percent, but a historically dry January and February with no significant storms forecast for March requires a reduction in the allocation to conserve available water supply. In addition to the 5 percent allocation, DWR will also provide any unmet critical health and safety needs of the 29 water agencies that contract to receive State Water Project supplies.
“We are experiencing climate change whiplash in real time with extreme swings between wet and dry conditions. That means adjusting quickly based on the data and the science,” said DWR Director Karla Nemeth. “While we had hoped for more rain and snow, DWR has been preparing for a third consecutive year of drought since October. We are continuing with a series of actions to balance the needs of endangered species, water supply conservation, and water deliveries for millions of Californians.”
DWR will make its next assessment of the State Water Project allocation following the next snow survey on April 1. A final allocation for the water year is typically announced in May or June. Read the full news release on the DWR News webpage.

DWR Begins Monitoring Vernal Pools
Some grasslands, including areas around Butte County, have an underlying impervious layer of rock or clay that causes rainwater to pond in the winter and spring, creating seasonal wetlands called vernal pools. Although vernal pools are only a small component of our local grasslands in terms of area, they support a remarkably high diversity of plants and animals, including rare and endangered species and species endemic to California (i.e., found nowhere else in the world).
Vernal pool organisms and plants are highly specialized to their unique environment and to the Mediterranean-type climate found in California. They have adapted to living in pools that fill in the winter but are completely dry by the summer, as well as adapting to the sometimes-extreme variability in temperature and rainfall between years. Vernal pools are important targets for conservation because most vernal pools in California have been lost to development, agriculture, and habitat degradation from invasive plants.
Vernal pools often support spectacular wildflowers that bloom from March to May. Each spring, Department of Water Resources (DWR) environmental scientists from the Oroville Field Division monitor hundreds of vernal pools around the Oroville area and make assessments on how protection measures for these valuable environmental resources are succeeding.
This year scientists are observing wildflowers blooming earlier, likely due to drought conditions, which has reduced the number of “wet” vernal pools found. Scientists also noticed that the areas where CAL FIRE performed controlled burns around the Thermalito Forebay last year to remove invasive grass buildup, or ‘thatch’, and other invasive plants, are abundant with flowers – demonstrating the benefit of such activity on area grasslands and vernal pools.

FEATHER RIVER HATCHERY STEELHEAD PLANTING
The Feather River Fish Hatchery raised over 630,700 steelhead for release this year. The steelhead were raised for a full year at the hatchery and averaged about 8 to 9 inches in length. Around 129,300 steelhead were released in the Thermalito Afterbay in December 2021 and February 2022. This is a significant increase from normal planting years and will contribute to a more productive recreational fishery. This is a significant increase from normal planting years and will contribute to a more productive recreational fishery.
The remaining approximately 501,400 steelhead were released into the Feather River at Boyd’s Pump Boat Launch Feb. 3 to Feb. 18 to meet mitigation requirements. Releasing these young fish further downstream improves their chance of survival. This shortened migration route allows juvenile fish to avoid predators.
Steelhead are a salmonid species and are an ocean-going trout. They will migrate from freshwater to marine (ocean), returning to freshwater environments to spawn. They can spawn several times during their lifetime and can live up to eight years. Their “steelhead” name comes from their appearance, a more streamlined shape than Chinook salmon and with a silvery or brassy color as an adult.
The Feather River Fish Hatchery is a California State Water Project (SWP) facility built in the late 1960s to mitigate impacts on fish migration resulting from the construction of Oroville Dam which prevented access to spawning grounds further upstream. The Department of Water Resources (DWR) maintains the facility and funds the hatchery operations, fish spawning, rearing, and stocking activities provided by California Department of Fish and Wildlife staff.

DWR SURVEY OF LAKE OROVILLE
DWR is conducting a bathymetric (underwater) survey of Lake Oroville to complete a comprehensive topography, or map, of the lakebed. The underwater survey will complement a December 2021 survey that took advantage of the lake’s low water elevations to perform an ‘above water level’ survey of Lake Oroville’s topography, dams, and related structures. Using highly accurate LiDAR remote sensing, the December survey produced precise, three-dimensional information of Lake Oroville’s lakebed.
Similar data will be collected from the bathymetric survey. Data from both surveys will provide DWR with up-to-date information that can be used to determine changes in sedimentation, update the reservoir’s storage-stage relationships, and inform future boat ramp extensions.

The Department of Water Resources (DWR) has a new website to better inform Californians about hydrologic conditions, forecasts, and information at the scale of their local watershed. The website, California Water Watch, allows the public to obtain a quick snapshot of local and statewide water conditions and was developed as part of the Governor’s drought emergency proclamation. Information is updated from a variety of data sources and will assist the public to research, learn, and stay informed about California’s most precious resource – water.

Lake Oroville Community Update - February 11

2/15/2022

February 11, 2022
Five Year Anniversary
February 2017 was a challenging time for Oroville residents and the surrounding communities. Over the past five years, the dam safety industry has been transformed statewide and nationally, leading to changes in how dams and related facilities are operated, inspected, and maintained. Public safety and flood protection remain the Department of Water Resources’ (DWR) top priorities in operational decisions regarding the Oroville reservoir.
The reconstruction of the Oroville Dam’s main and emergency spillways using a more robust and modern design ensures that the Oroville Dam will continue to be able to provide flood protection to downstream communities.
The Oroville Dam Comprehensive Needs Assessment (2020) identified priorities and appropriate solutions to bolster the integrity and resiliency of the Oroville Dam Complex; projects completed or underway include a seismic retrofit study, assessment of the FCO gate structure, installation of piezometers at Oroville Dam to collect data on seepage, and studies of area geology.
Transparency, public engagement, and open communication also remain priorities as DWR works to restore trust and build relationships. Although the COVID-19 pandemic has restricted personal outreach and in-person community presentations, DWR continues to share information virtually regarding annual milestones, weather forecasts and operational updates, and engage community members in dialogue about needs and concerns. Residents are encouraged to participate in the Oroville Dam Citizens Advisory Commission that meets every three months.
DWR is thankful to all the impacted residents for their patience and partnership as we move forward to achieve our shared goals of public safety, a reliable water supply for the state, environmental protections, and recreation opportunities for residents and visitors.
Law Enforcement Training
The Butte County Sheriff’s Office held an emergency response training at the Ronald B. Robie Thermalito Pumping-Generating Powerplant today (Feb. 11) which involved law enforcement and public safety personnel and equipment. The Sheriff’s Office advised the public this was a training exercise to provide participants with “real-time” response and rescue experiences to learn and refresh skills related to emergency preparedness and response. The Thermalito Powerplant remains fully operational.

CHRISTMAS TREE FISH HABITAT
DWR, the California Conservation Corps (CCC), and the California Department of Fish and Wildlife (CDFW) completed constructing fish habitat structures at Lake Oroville and the Thermalito Afterbay using over 1,240 recycled Christmas trees. The trees were again collected by Chico Boy Scout Troop 2 and delivered free of charge to DWR by Recology, a local waste management company.
To create the habitat on Lake Oroville and the Thermalito Afterbay, members of the CCC team bundle the recycled holiday trees together and anchor them in various locations around the lakebed. At Lake Oroville near the Loafer Creek Recreation Area, 916 trees were assembled into 64 structures. At the Thermalito Afterbay, 324 trees were assembled into 32 structures. Anchoring the trees allows them to remain submerged, providing juvenile fish safe refuge, and improving fisheries and recreational fishing opportunities.
For nearly 30 years, DWR has worked with local groups to construct fish habitat structures, which is one of the longest continuously running fish habitat improvement programs in the State of California. The 2022 project is anticipated to be completed by Feb. 9.
LAKESIDE ACCESS ROAD
Construction activities associated with the Lakeside Access Road project continue to result in intermittent closures of the Oroville Dam Crest parking lot on the northwest side of the dam as well as the Spillway Boat Ramp area. These short duration closures are anticipated to continue until the end of February.

Oroville Recreation Advisory Committee
The Oroville Recreation Advisory Committee will hold a public virtual meeting on Friday, Feb. 4 at 9 a.m. Interested persons can join the meeting on Zoom at https://ca-water-gov.zoom.us/j/86898170840?pwd=VmRadjZsQmQrVGpJWk1jayt1UHI5Zz09 or visit the DWR Events webpage.

ORAC was established by the Federal Energy Regulatory Commission (FERC) to review and provide recommendations regarding DWR’s recreation plan for the Project-2100 – Oroville Facilities. The 13-member committee is made up of representatives from state and local government, sports and recreation groups, and business and community organizations.
Loafer Point Boat Ramp
The Loafer Point Stage II boat ramp has reopened for boat launching. The first construction phase of the new boat ramp was completed in May 2021, adding six boat launch lanes to 707 feet, 180 trailered parking spaces, and offering immediate access to the open waters of Lake Oroville. Falling lake levels due to drought conditions forced its closure a month later in June 2021.

Taking advantage of historic low lake elevations, construction to extend three of the six boat launch lanes further into the lakebed to improve low-water access to Lake Oroville began the first week of October and succeeded in constructing lanes to 675 feet before rising lake elevations prevented further work. With lake elevations currently at 744 feet, all six lanes of the Stage II boat ramp are currently available.

The Loafer Point Stage I boat ramp was completed in 2020 and added three new boat launch lanes from a full lake down to 805 feet, a new parking area, and a restroom facility. Both boat ramps are adjacent to the Loafer Creek Recreation Day Use Area and Campground, rounding out a full-service recreation destination with nearby trails, campgrounds, boating, and marina. Excepting the Loafer Point Stage II boat ramp and the trails network, the remainder of the Loafer Creek Recreation Area is currently closed due to waterline repair. Trails within the Loafer Creek Recreation Area can be accessed from the Bidwell Saddle Dam Trailhead located on Kelly Ridge Road.

DWR Issues Revised Water Allocation
Due to the series of storms in December 2021, the Department of Water Resources (DWR) has increased the State Water Project (SWP) allocation to 15 percent of requested supplies for 2022, an increase over the December allocation that covered only critical health and safety needs of the 29 water agencies that contract to receive State Water Project supplies.

While drought conditions still persist, December’s precipitation enabled DWR to convey and store water in San Luis Reservoir, allowing for the modest increase in water deliveries. DWR continues to plan for a third dry year by preserving storage in Lake Oroville, the State Water Project’s largest reservoir. Water releases from Lake Oroville will be prioritized to maintain Delta water quality, protect endangered species, and meet senior water right needs.

Each year, DWR makes an initial SWP allocation on Dec. 1. Allocations are updated as snowpack and runoff information are assessed, with a final allocation typically determined in May or June. Read the full news release on the DWR News webpage.

Drought Update
January’s dry weather reflects California’s weather variability -- not only from year to year but within the water year as well (Oct. 1 to Sept. 30). California has received more precipitation this water year as compared to this time last year but the abrupt change from December’s series of strong storms to a very dry January is a kind of “weather whiplash” that is becoming more common as climate change impacts continue to grow.

The remainder of the wet season is still ahead. California receives 75 percent of its precipitation from November through March, half of which is typically received between December through February. Currently the statewide snowpack is around 58 percent of seasonal average and about 113 percent of average for this date. California needs above average precipitation throughout the winter to offset record-setting drought conditions and replenish reservoirs. Currently, Lake Oroville is only filled to 44 percent of its capacity and major reservoirs across the state are at an average of 42 percent capacity.

Governor Newsom has called on Californians to voluntarily reduce their water use by 15 percent with simple measures to protect water reserves. The October 2021 emergency proclamation expanded the drought emergency statewide and authorized the State Water Board to ban wasteful water uses, boosting conservation efforts.

Mid-Winter Bald Eagle Survey
Environmental scientists from DWR participated in the National Midwinter Bald Eagle Survey on Jan. 7. This nation-wide effort, coordinated by the U.S. Army Corps of Engineers, aims to determine bald eagle distribution and identify areas of important winter habitats. Because of bad weather on the day of the national survey, this year’s official count at Lake Oroville was only 20 bald eagles; however, an informal survey two days later counted well over 100 migrating eagles at the lake.

Lake Oroville, the Feather River, and local area rice fields provide an ideal habitat for bald eagles. Fish are one of the eagle’s main food sources and water bodies like Lake Oroville, rivers, and rice fields provide a wide variety of fish and other favorite food sources such as waterfowl, small birds, and mammals. The many trees and snags (tall dead trees) near water areas provide prime roosting and hunting locations for the bald eagles that migrate to and through the area during the winter months as well as nesting opportunities for Lake Oroville’s resident “nesting pairs” who have established their home here.

Protecting the area’s year-round bald eagle population living in the DWR Oroville-Thermalito Complex jurisdiction is the responsibility of DWR environmental scientists. The bald eagle is a protected species under the Migratory Bird Treaty Act of 1918 and Bald and Golden Eagle Protection Act of 1940. They were listed as an endangered species in 1978. Those protections have been successful, and the species is now federally delisted. DWR’s scientists monitor for and, if necessary, act against threats such as public intrusions, habitat loss, or other impacts to the eagles’ nesting areas.

Mid-Winter Bald Eagle Survey
Environmental scientists from the Department of Water Resources (DWR) recently participated in the National Midwinter Bald Eagle Survey on Jan. 7. This nation-wide effort, coordinated by the U.S. Army Corps of Engineers, aims to determine bald eagle distribution and identify areas of important winter habitats. Because of bad weather on the day of the national survey, this year’s official count was only 20 bald eagles; however, an informal survey two days later counted well over 100 migrating eagles.

Hyatt Powerplant Returns to Service
Oroville Dam’s Hyatt Powerplant returned to service on Jan. 1, 2022 after going offline on Aug. 5, 2021 due to historic low lake levels driven by the state’s ongoing severe drought conditions. An unexpectedly strong atmospheric river storm in late October, followed by a series of powerful December storms, has increased reservoir elevation levels from 630 feet on Oct. 21 to 733 on Jan. 14 – a gain of over 100 feet. Water levels are now well above the powerplant’s intakes, providing the necessary water pressure for efficient operation of the plant.

Currently, Hyatt powerplant is utilizing one generating unit to produce electricity and supply it to the state’s electrical grid managed by the California Independent System Operator. Hyatt generation will initially remain low due to low agricultural demands and improved delta salinity conditions. DWR anticipates an average outflow of about 900 cubic feet per second, which will generate approximately 30 megawatts of power. As lake levels rise and demands increase, additional units will be brought back online.

DWR completed major maintenance activities while the powerplant was offline to ensure the plant maintains its reliability and is available for water deliveries and power generation. DWR continues to manage Lake Oroville to balance storage needs with requirements for Delta outflows, water quality, and public health and safety requirements in an effort to conserve as much storage as possible in the event of another dry year. Read the news release at DWR News Releases.

25th Anniversary of 1997 Floods
At the start of the new year in 1997, an atmospheric river from the warm waters near Hawaii, what used to be called a “pineapple express”, drenched the Sierra foothills – up to 40 inches of precipitation over the course of the storm in some locations. Multiple rivers and flood channels overflowed, and areas up and down California’s Central Valley experienced breached levees, flooded farmland, and inundated towns and highways. The result was over $2 billion in damage and three lives lost.

In the years since, the Department of Water Resources (DWR), through key improvements in forecasting, resources, levee infrastructure, and reconnected floodplain, has worked tirelessly with multiple partners to improve California’s ability to predict, prepare for, and respond to atmospheric river storms that often cause such damaging flood events. Read more about these efforts and find links to this year’s coverage of the anniversary on the DWR Updates webpage.

Drought Update
California continues to benefit from winter storms, bringing much needed rain and snow to the state. On average, California receives 75 percent of its precipitation from November through March, half of which is typically received between December through February. The record-setting late October atmospheric river storm and the series of strong storms in December are providing a good start to the Sierra snowpack currently at around 58 percent of seasonal average and about 126 percent of average for this date.

California needs above average precipitation throughout the winter to offset the record-setting drought conditions. Currently, Lake Oroville is only filled to 43 percent of its capacity and major reservoirs across the state are at an average of 41 percent capacity.

The outlook for the rest of the winter is for the weather to turn drier in the new year. While there may be more dry days than wet, large atmospheric rivers can still occur, depositing substantial precipitation in a short period as we saw in October. This raises the risk of flood events, especially in burn scar areas.
Lakeside Access Road
Construction activities associated with the Lakeside Access Road project will result in intermittent closures of the Oroville Dam Crest parking lot on the northwest side of the dam. These short duration closures are anticipated to continue until the end of January. The popular walking/bicycling trail across the top of the dam will remain open and parking will continue to be available at the Upper Overlook.

This project will consist of a new, permanent, paved road from the west side of Oroville Dam to the Spillway Boat Ramp parking lot on the “lakeside,” or waterside, of the Oroville Dam spillways. This new road will allow a more direct route when water levels are low in Lake Oroville. The new road will include two concrete traffic lanes, wide shoulders for walking and biking, guardrails, and safety signage.

Lake Oroville Community Update - January 7

1/12/2022

January 7, 2022
Hyatt Powerplant Returns to Service
Oroville Dam’s Hyatt Powerplant returned to service on Jan. 1, 2022 after going offline on Aug. 5, 2021 due to historic low lake levels driven by the state’s ongoing severe drought conditions. An unexpectedly strong atmospheric river storm in late October, followed by a series of powerful December storms, has increased reservoir elevation levels from 630 feet on Oct. 21 to 724 on Jan. 7 – a gain of over 90 feet. Water levels are now well above the powerplant’s intakes, providing the necessary water pressure for efficient operation of the plant.

Currently, Hyatt powerplant is utilizing one generating unit to produce electricity and supply it to the state’s electrical grid managed by the California Independent System Operator. Hyatt generation will initially remain low due to low agricultural demands and improved delta salinity conditions. DWR anticipates an average outflow of about 900 cubic feet per second, which will generate approximately 30 megawatts of power. As lake levels rise and demands increase, additional units will be brought back online.

The opportunity to perform maintenance on the powerplant’s infrastructure while the plant was offline allowed staff to enter equipment across the plant to perform inspections and replace protective equipment to ensure the plant maintains its reliability and is available for water deliveries and provision of clean hydropower to help meet the state’s clean energy goals in the upcoming water year. Read the news release at DWR News Releases.

25th Anniversary of 1997 Floods
At the start of the new year in 1997, an atmospheric river from the warm waters near Hawaii, what used to be called a “pineapple express”, drenched the Sierra foothills – up to 40 inches of precipitation over the course of the storm in some locations. Multiple rivers and flood channels overflowed, and areas up and down California’s Central Valley experienced breached levees, flooded farmland, and inundated towns and highways. The result was over $2 billion in damage and three lives lost.

In the years since, the Department of Water Resources (DWR), through key improvements in forecasting, resources, levee infrastructure, and reconnected floodplain, has worked tirelessly with multiple partners to improve California’s ability to predict, prepare for, and respond to atmospheric river storms that often cause such damaging flood events. Read more about these efforts and find links to this year’s coverage of the anniversary on the DWR Updates webpage.

Drought Update
California continues to benefit from winter storms, bringing much needed rain and snow to the state. On average, California receives 75 percent of its precipitation from November through March, half of which is typically received between December through February. The record-setting late October atmospheric river storm and the series of strong storms in December are providing a good start to the Sierra snowpack currently at around 57 percent of seasonal average and about 144 percent of average for this date.

California needs above average precipitation throughout the winter to offset the record-setting drought conditions. Currently, Lake Oroville is only filled to 40 percent of its capacity and major reservoirs across the state are at an average of 37 percent capacity.

The outlook for the rest of the winter is for the weather to turn drier in the new year. While there may be more dry days than wet, large atmospheric rivers can still occur, depositing substantial precipitation in a short period as we saw in October. This raises the risk of flood events, especially in burn scar areas.
Loafer Creek Recreation Area
The Loafer Creek Recreation Area at Lake Oroville continues to be temporarily closed due to damages and interruption of the park’s main water supply system.

Current Lake Operations
The elevation of Oroville’s reservoir is about 720 feet elevation and storage is about 1.41 million acre-feet, which is 40 percent of its total capacity and 75 percent of historical average. Dry and cool conditions are forecast over the weekend with a chance of rain next week.

The average daily inflows from the storm activity the last week of December were in the range of 15,000 cfs to 17,000 cfs and are forecasted to taper to between 7,000 cfs to 9,000 cfs through the weekend. Inflows for the week of January 10 are projected in the range of 5,000 cfs to 6,000 cfs. Inflows are subject to change based upon on actual weather conditions and snow elevations.

Total flows to the Feather River are at 950 cfs for meeting downstream water quality and flow requirements. Flow in the low-flow channel, through the City of Oroville, is 650 cfs and flow through the Thermalito Afterbay Outlet is 300 cfs. Releases are assessed daily.

Atmospheric Rivers
California continues to benefit from winter storms, bringing much needed rain and snow to the state. On average, California receives 75 percent of its precipitation from November through March, half of which is typically received between December through February. December storms are providing a good start to the Sierra snowpack currently at around 30 percent of seasonal average and about 102 percent of average for this date.

California needs above average precipitation throughout the winter to offset the record-setting drought conditions. The outlook for the rest of the winter is for the weather to turn drier in the new year. While there may be more dry days than wet, large atmospheric rivers can still occur, depositing substantial precipitation in a short period as we saw in October, raising the risk of flood events, especially in burn scar areas.

Year in Review
The year 2021 has been a unique and challenging year. Faced with continued COVID-19 public health restrictions, the Dixie Fire, and historic low lake levels, the Department of Water Resources’ (DWR) Oroville Field Division (OFD) rose to the challenge of operating the Oroville-Thermalito Complex smoothly. Here are a few highlights here at the Oroville-Thermalito Complex:

Extreme drought conditions continued across the West and despite recent atmospheric river storms and snowfall, California remains in a state of climate water deficit. Accelerating climate change impacts also impacted Lake Oroville, the headwaters of California’s State Water Project (SWP), which fell to 628.97 feet elevation – the lowest since the lake was filled in 1968.

Historic low lake levels also took the Hyatt Powerplant offline on Aug. 5, 2021. OFD staff were able to complete major maintenance activities while the powerplant was offline, ensuring the plant maintains its reliability and is available for water deliveries and clean hydropower generation.

An unexpected atmospheric river “Bomb Cyclone” rain event arrived in late October to increase Lake Oroville’s elevation by 30 feet in one week. With additional precipitation events throughout December, Lake Oroville has gone from 37 percent of its historical average to 64 percent as of Dec. 22, with continued rain and snow forecasted for the remainder of the year. While not enough to end the current drought, recent storms are a welcome wet finish to a very dry year.

Drought conditions affect wildlife and fish as well. California Department of Fish and Wildlife (CDFW) staff at DWR’s Feather River Fish Hatchery successfully harvested additional Chinook salmon eggs this fall to offset drought impacts to the Feather River fishery and plans to plant an extra 1.7 million fish in 2022. CDFW staff in the Oroville Wildlife Refuge successfully timed their dry-land planting of grasses, flowers, and grains this spring where late spring rain resulted in over 140 acres of forage for both local and migrating birds. Wildfowl are also benefiting this winter from a public-private partnership between DWR, local organizations, and rice farmers to selectively flood rice paddies for support of the millions of migrating birds who travel the Pacific Flyway.

Fire again burned in the Feather River watershed where the Dixie Fire consumed nearly a million acres, requiring DWR to join in repeating last year’s North Complex Fire efforts to install erosion control measures to prevent toxic ash and burned materials from entering the waterways that supply Lake Oroville. DWR and OFD staff, as key members of the Feather River Watershed Working Group led by California Waterboards and Governor’s Office of Emergency Services, expanded the Department’s previous North Complex Fire work to address wildfire impacts on water quality. This included debris flow measurement, cleanup, and additional water sampling activities.

OFD also embarked on ambitious improvements including construction of a new boat ramp facility at Loafer Point with two stages reaching elevations of 800- and 681-feet elevation respectively to improve low water access, as well as added additional boat ramp lanes at Bidwell Canyon, including doubling the size of the Stage II boat ramp parking area.

Projects were also started to increase knowledge about the Feather River fishery and improve water control facilities such as the Thermalito Afterbay outlet and Palermo Tunnel intake in Lake Oroville. OFD staff also closely collaborated with CAL FIRE and local partners to address acres of burned and overgrown vegetation through DWR’s Fuel Load Management Program and CAL FIRE’s Vegetation Management Program.

DWR is looking forward to initiating and completing more projects in 2022 at the Oroville-Thermalito Complex. The Lake Oroville Community Update will continue to share news and information with the community. Your thoughts, comments, and questions to oroville@water.ca.gov are always welcome.
Current Lake Operations
The elevation of Oroville’s reservoir is about 689 feet elevation and storage is about 1.17 million acre-feet, which is 33 percent of its total capacity and 64 percent of historical average. Wet and cold conditions are forecasted this weekend into the early part of next week with up to four inches in the Feather River Basin Saturday through Tuesday. The higher elevations are expected to see heavy snow accumulation on Sunday with continued snow accumulation in the early part of the week.

Inflows to Lake Oroville from the recent storm on Thursday and Friday have been upwards of around 20,000 cubic per second (cfs) and expected to be in the range of 7,000 cfs to 13,000 cfs during the weekend into next week . However, the storms are colder in the beginning of the week and inflows are subject to change based upon on actual weather conditions and snow elevations.

Total flows to the Feather River are at 950 cfs for meeting downstream water quality and flow requirements. Flow in the low-flow channel, through the City of Oroville, is 650 cfs and flow through the Thermalito Afterbay Outlet is 300 cfs. Releases are assessed daily.

The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center at www.cdec.water.ca.gov. Lake Oroville is identified as “ORO”.

December 10, 2021
State Water Project Allocation
The Department of Water Resources (DWR) announced the initial State Water Project (SWP) allocation for 2022 on Dec. 1, along with several steps to manage the state’s water supply in anticipation of a third dry year with reservoirs at or near historic lows. The Dec. 1 allocation will focus on the health and safety needs of the 29 water agencies that contract to receive SWP supplies. The SWP will not be planning water deliveries through its typical allocation process until the state has a clearer picture of the hydrologic and reservoir conditions going into the spring. (Hydrology is the study of movement of water in relation to land – including water from precipitation and snowmelt.)

DWR is focused on prioritizing water supply in four categories: water for health and safety needs and Delta salinity control; water for endangered species; water to reserve in storage; and water for additional supply allocations if the hydrology allows. Water in Lake Oroville will be reserved to maintain Delta water quality, protect endangered species, and meet senior water right needs.

Beyond minimal exports to meet South Bay health and safety needs, water stored in Lake Oroville will be used for south of Delta deliveries only if hydrology conditions improve. South of Delta deliveries will be met with water available from the Delta as well as water stored in San Luis Reservoir. The full news release can be viewed on the DWR News Releases webpage.
Oroville Dam Citizens Advisory Commission Public Meeting
The California Natural Resources Agency (CNRA) held its ninth Oroville Dam Citizens Advisory Commission meeting on Dec. 3, 2021. The online public meeting included presentations about downstream flood management and preparedness as well as an update on the Water Control Manual from a representative of the U.S. Army Corps of Engineers. Members of the public also offered comments and asked questions. The Citizens Advisory Commission is a forum to provide public feedback from the communities surrounding Oroville Dam. The meeting transcript and presentations will be available on the Commission’s website in the coming weeks at https://bit.ly/OrovilleCAC.
New Invasive Plants Discovered
Environmental scientists with the Department of Water Resources (DWR) Oroville Field Division have discovered a new aquatic invasive plant in the Feather River downstream of Oroville. The new floating aquatic plant is the South American spongeplant (Limnobium spongia), previously known from the Sacramento River and the Sacramento-San Joaquin Delta. This is the second new, high-rated (by the California Invasive Plant Council) invasive plant species DWR has discovered in the Feather River in the last three years. In 2019, alligator weed (Alternanthera philoxeroides) was found adjacent to the Feather River Outlet Boat Ramp. Neither of these species were previously known in Butte County but have been expanding in recent years across California.

Aquatic invasive species (AIS) move from one area to another via watercraft, personal water gear, pets who have entered the water, and by wildlife. You can help minimize the spread of AIS by thoroughly inspecting all equipment after leaving a waterbody; clean any visible mud and plants from watercrafts, equipment, and personal gear; and drain water from all equipment, including bait buckets, and ballast tanks. Cleaning and drying anything that came in contact with water (including pets and clothing) will help prevent the spread of AIS.

Invasive plants can de-stabilize dissolved oxygen cycles needed by fish and aquatic organisms, crowd out native plants, shade out crucial shallow-water fish habitat, obstruct waterways and navigational channels, and block agricultural and municipal water intakes.

Current Lake Operations
The elevation of Oroville’s reservoir is about 673 feet elevation and storage is about 1.06 million acre-feet, which is 30 percent of its total capacity and 59 percent of historical average. Heavy precipitation in Oroville and snow accumulation in the higher elevations are forecasted for the Feather River Basin beginning Sunday and extending into Monday with continuing snow showers into the higher elevations mid-week. The Feather River basin may see 5 to 7 inches as a result of these storms. Temperatures will range in the 20s and 30s in the higher elevations and upper 40s and low 50s in the valley.

Inflows to Lake Oroville have been ranging around 500 to 1,000 cubic feet per second (cfs) and are expected to increase early next week in response to the heavy precipitation. Current forecasts indicate potential inflows of about 10,000 cfs (subject to change based upon on actual weather and soil conditions). At 30 percent capacity, there is sufficient storage to manage these inflows.

Total flows to the Feather River are at 1,500 cubic feet per second (cfs) for meeting downstream water quality and flow requirements. Flow in the low-flow channel, through the City of Oroville, is 650 cfs and flow through the Thermalito Afterbay Outlet is 850 cfs. Releases are assessed daily.
