Governor Visits Fuels Reduction Work
Governor Gavin Newsom visited the Loafer Creek Recreation Area near Lake Oroville to sign a $536 million wildfire package on April 13. This money will go towards forest management projects and efforts to reduce wildfire risks around California, including projects in Butte County. 
 
Governor Newsom visited a work site where CAL FIRE, in partnership with Department of Water Resources (DWR), has crews actively working in the Loafer Creek Recreation Area within the North Complex wildfire burn scar. Crews are using heavy machinery and hand crews to cut, pile, and chip burnt vegetation and trees. The piles will be burned after rains begin later this fall. Operations are visible to motorists on Highway 162.

This work is part of CAL FIRE’s Vegetation Management Program and DWR’s Fuel Load Management Plan (FLMP). Both plans aim to reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville. Nearly 3,000 acres are targeted as part of DWR’s FLMP. To date, approximately 700 acres have been treated around the Lake Oroville area by DWR and its partners including CAL FIRE, the California Conservation Corps, Butte County Fire Safe Council (BCFSC), Butte County Sheriff’s Office, and California Department of Parks and Recreation (CA Parks). Previous FLMP work in the Loafer Creek area is credited for helping slow the North Complex wildfire, allowing firefighters time to establish the fire line that protected the communities of Kelly Ridge and Oroville.

DWR, in partnership with BCFSC, will begin a vegetation management project along Highway 162 and Loafer Creek Road starting the week of April 19. This 13-acre project will take approximately one month to reduce overgrown vegetation and hazardous fuels. A one-lane road closure may be needed along the entrance to Loafer Creek Recreation Area. The public is advised to use caution around work activities and reduce speeds around crews and equipment.

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.

Additional Campgrounds Open at Lake Oroville
The California Department of Parks and Recreation (CA Parks) has opened their camping reservations for group camping at Loafer Creek Recreation Area, including the Equestrian Group campground, the Bloomer Point, Bloomer Knoll, and Bloomer Cove boat-in campgrounds, the Foreman Creek boat-in campground, and the floating campgrounds located around Lake Oroville. Lime Saddle group camping remains closed. 

Reservations for camping can be made online by selecting the ‘Reservations’ tab on the Lake Oroville State Recreation Area (LOSRA) webpage. The reservations system needs 48 hours’ notice to process reservations. “Day-of” access to campgrounds is possible if campsites are available.

Current Lake Operations
The elevation of Oroville’s reservoir is about 728 feet elevation and storage is about 1.48 million acre-feet -- 42 percent full and 54 percent of historical average. Currently, in the Northern Sierra Basin, rainfall is below average, at 49 percent of normal for this time of year and snowpack is also below average at 39 percent of normal. Dry and warm conditions are forecasted this weekend and into the week of April 19.

DWR continues plans to reduce releases to conserve water while maintaining flows to meet Bay-Delta water quality needs and outflow requirements. On Friday, total flows to the Feather River were reduced to 1,100 cfs. At this total Feather River flow, there is 800 cfs down the low flow channel through the City of Oroville and 300 cfs through the Thermalito Afterbay Outlet (Outlet). 

From April 19 to April 21, releases to the Feather River will decrease from the current 1,100 cfs to 800 cfs by Wednesday, April 21. At that time, flows down the low flow channel through the City of Oroville will be 650 cfs and 150 cfs from the Thermalito Afterbay Outlet (Outlet) for a total of 800 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. Lake Oroville is identified as “ORO”.

Goats Reduce Vegetation Near Diversion Pool
A herd of 350 to 400 goats from Hanski Family Farms LLC were successful in reducing hazardous fuels in nearly five acres in the Lakeland Boulevard area this past week. DWR partnered with the Butte County Fire Safe Council (BCFSC) on this grazing project to reduce the fire risk from grasses, leaves, invasive and non-invasive plants, and other vegetation. 

This work is part of DWR’s Fuel Load Management Program, which was started in 2012 to reduce hazardous fuels within the Federal Energy Regulatory Commission (FERC) project boundary. DWR, along with partners CAL FIRE, the California Conservation Corps, BCFSC, Butte County Sheriff’s Office, and California Department of State Parks and Recreation (CA Parks), are all working together to accomplish the same common goal -- reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville. To date, approximately 675 acres have been treated around the Lake Oroville area by DWR and its partners.

DWR April Snow Survey
The Department of Water Resources (DWR) conducted the fourth snow survey at the Phillips Station snow course (El Dorado County) on April 1. The manual survey recorded 49.5 inches of snow depth and a snow water equivalent (SWE) of 21 inches, which is 83 percent of average for this location. The SWE measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. April 1 is typically when California’s snowpack is the deepest and has the highest SWE.
 
While the Southern Sierra remains well below average for both rain and snow, the picture is somewhat different in the Northern and Central part of the state where California typically receives 75 percent of the state’s annual precipitation. The few storms that impacted California this year have been colder, bringing more snow than rain. Colder systems are good for the Sierra snowpack, which accounts for 30 percent of California’s fresh water supply in an average year.
For Water Year 2021, the snowpack in the Northern and Central Sierra peaked at 70 percent of average; however, rain is below 50 percent of average, which ties this year for the third driest year on record. The amount of water expected to enter California’s reservoirs when the snowpack melts is projected to be just 58 percent of average. The full news release is available on DWR’s website.

DWR Adjusts State Water Project Allocation    
As California experiences a second consecutive dry year, DWR announced on March 23 an adjustment to its initial State Water Project (SWP) allocation for the 2021 water year. The Department now expects the SWP to deliver 5 percent of requested supplies this year, down from the initial allocation of 10 percent announced in December.

Allocations represent the amount of SWP water that DWR will deliver to 27 million Californians and 750,000 acres of farmland for the year and are reviewed monthly based on several factors, such as water in storage, environmental requirements, and rain and snowmelt runoff projections. 

Drought conditions have a significant impact on the state’s water supply. Lake Oroville storage is only at 53 percent of its historical average. Beginning April 6, outflows to the Feather River will be further reduced to conserve storage while maintaining the Feather River flows necessary for fishery, environmental, and water delivery needs. More information on the allocation change is available in the DWR News Release.
Additional Campgrounds Open at Lake Oroville
The California Department of Parks and Recreation (CA Parks) has opened up reservations for the Bloomer Point, Bloomer Knoll, and Bloomer Cove boat-in campgrounds, the Foreman Creek boat-in campground, and the floating campgrounds located around Lake Oroville.

Goats to Remove Vegetation Near Diversion Pool
The arrival of 350 to 400 goats from Hanski Family Farms LLC to the Lakeland Boulevard area was delayed this week but is now set to begin on Monday, April 5. DWR partnered with the Butte County Fire Safe Council (BCFSC) on this grazing project to reduce hazardous fuels on approximately five acres. The goats should be in the area for about one week.

The goats will graze on grasses, leaves, invasive and non-invasive plants including poison oak, and a variety of shrubs and trees. The grazing area will be cordoned off with an electric fence and monitored by herders and livestock guardian dogs to protect the animals. The public is urged to stay clear of the electric fence and keep pets away, so the goats are not disturbed.

This work is part of DWR’s Fuel Load Management Program, which was started in 2012 to reduce hazardous fuels within the Federal Energy Regulatory Commission (FERC) project boundary. DWR, along with partners CAL FIRE, the California Conservation Corps, BCFSC, Butte County Sheriff’s Office, and California Department of State Parks and Recreation (CA Parks), are all working together to accomplish the same common goal -- reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville. To date, approximately 675 acres have been treated around the Lake Oroville area by DWR and its partners.

Current Lake Operations
The elevation of Oroville’s reservoir is about 722 feet elevation and storage is about 1.43 million acre-feet -- 41 percent full and 54 percent of historical average. Currently, in the Northern Sierra Basin, rainfall is below average, at 51 percent of normal for this time of year and snowpack is also below average at 63 percent of normal. Less than a half an inch of rain is forecasted Sunday and Monday with cooler temperatures and a slight chance of rain forecasted during the week of April 5.

On April 1, DWR increased total releases to the Feather River to 1,500 cfs to provide a pulse flow to assist in the out-migration of Feather River Hatchery Spring-run Chinook salmon that were released on April 1 into the Feather River at the Boyd’s Pump Boat Launch. 

On April 3, DWR will begin ramping down total releases to the Feather River by 200 cfs a day. By April 6, total flows to the Feather River are planned to be at 800 cfs to conserve storage with 600 cfs down the low flow channel through the City of Oroville and 200 cfs from the Thermalito Afterbay Outlet (Outlet) for a total of 800 cfs for the Feather River’s high flow channel 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. Lake Oroville is identified as “ORO”.

Reducing Climate Change Impacts at Thermalito Powerplant
An old electricity-generating turbine at the Ronald B. Robie Thermalito Pumping-Generating Powerplant (Thermalito Powerplant) has been replaced with a new energy efficient model that will help DWR achieve its goal of using 100 percent zero-emission resources by 2045.

The new Kaplan turbine allows more clean hydropower to be generated from the same water releases and deliveries, an increase in efficiency from 86 percent to 93 percent, providing even more clean energy to California’s electrical grid. It will also reduce greenhouse gas emissions by nearly 1,000 metric tons per year, helping DWR further reduce its carbon footprint.

The Thermalito turbine project is partially funded by California Climate Investments, a statewide initiative that puts billions of cap-and-trade dollars to work. Learn more about how the new turbine at the Thermalito Powerplant is helping California meet its clean energy goals by watching our new video and reading the latest DWR Update. For more information on DWR’s renewable energy initiatives, visit our clean energy webpage.

Monument Hill Facility
Improvements at the Monument Hill Boat Ramp and Day Use Area’s boat ramp and beach have been completed. The Department of Water Resources (DWR) placed 45 cubic yards of sand on the public beach, repaired storm erosion, and corrected movement of the boarding float at the boat launch. The Monument Hill facility on the Thermalito Afterbay is off Highway 162 near State Route 99.

The Thermalito Afterbay, part of the Department’s Oroville-Thermalito Complex, is a large water supply and hydropower generation reservoir in the Oroville Wildlife Area (OWA). The California Department of Fish and Wildlife (CDFW) manages the wildlife resources of the OWA for DWR.

Reopening Additional Area at Thermalito Diversion Pool
During the recovery from the 2017 Oroville Spillways Incident, the exclusion zone and buoy line in the Thermalito Diversion Pool below Oroville Dam was temporarily extended approximately one-half-mile downstream. The exclusion zone has been reduced and the buoy line moved back upstream to its historical location just below the spillway, reopening additional area for public access.

Reopening Additional Area at Thermalito Diversion Pool
During the recovery from the 2017 Oroville Spillways Incident, the exclusion zone and buoy line in the Thermalito Diversion Pool below Oroville Dam was temporarily extended approximately one-half-mile downstream. This week, the exclusion zone has been reduced and the buoy line moved back upstream to its historical location just below the spillway, reopening additional area for public access. 

The Thermalito Diversion Pool provides opportunity for non-motorized water sports including kayaking, canoeing, and swimming. A car-top boat launch is available off of Cherokee Road. The upper end of the Diversion Pool near the spillway and dam, while open for fishing from the southern shoreline, excludes watersports, including swimming, wading, and paddle sports. Access to this area is available from the Brad Freeman Trail as well as from the new parking area off Oro Powerhouse Road (Oroville Dam Boulevard East towards Kelly Ridge, turn onto Oro Powerhouse Road and make immediate left before reaching the Hyatt Powerplant entrance gate). 
Water Wednesday Focus on the Feather River Watershed         
The Department of Water Resources Water Wednesday program just completed a series of episodes on watershed health, including a focus on the Feather River watershed that drains into Lake Oroville. Four February episodes discussed how a watershed works; wildfire impacts on watersheds and water quality; how DWR staff work to protect sensitive environments and species; and the anticipated impacts climate change may have on California’s watersheds.

Water Wednesday episodes, started in 2020 to provide online, interactive education to students, cover a wide range of ‘water-oriented’ topics of interest to many viewers and are available on DWR’s YouTube page.

Bald Eagles Build New Nest
A nesting pair of bald eagles that lost their nest tree in the North Complex Fire have returned. Environmental scientists with the Department of Water Resources have located a newly built nest in an undamaged tree within their territory and observed nesting activity on the new nest by the pair.

Lake Oroville and the Feather River area provide ideal habitat for bald eagles. Fish are one of the eagles’ main food sources and large water bodies like Lake Oroville provide a wide variety of fish as well as other favorite food sources such as waterfowl, small birds, and mammals. The many trees and snags (tall dead trees) near water areas provide prime nesting, roosting, and hunting locations.
 
Protecting the area’s year-round bald eagle population living in the Department of Water Resources’ (DWR) Oroville-Thermalito Complex jurisdiction is the responsibility of the Oroville Field Division’s 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.

The elevation of Oroville’s reservoir is about 713 feet elevation and storage is about 1.35 million acre-feet - 38 percent full and 54 percent of historical average. Currently, in the Northern Sierra Basin, rainfall is below average, at 49 percent of normal for this time of year and snowpack is also below average at 61 percent of normal. A break in the rain this weekend with continuing chance of rain and colder temperatures in the early part of the week of March 8.

The total releases to the Feather River are 1,050 cubic feet per second (cfs) to conserve storage in Lake Oroville. The Feather River flows will consist of 800 cfs down the Low Flow Channel through the City of Oroville, and 250 cfs from the Thermalito Afterbay Outlet (Outlet) for a total of 1,050 cfs for the Feather River’s high flow channel downstream of the Outlet.

Oroville Dam Citizens Advisory Commission Public Meeting
The California Natural Resources Agency held its sixth Oroville Dam Citizens Advisory Commission meeting on Feb. 19. The online public meeting included presentations on fire modernization at the Hyatt Power Plant, winter operations, and a presentation from the Yuba Water Agency on downstream flood management. Members of the public also asked questions and gained information on these and other topics. The Citizens Advisory Commission is a forum for the community to provide feedback and ask questions. The meeting transcript and presentations will be available on the Commission’s website (https://bit.ly/OrovilleCAC) in the coming weeks.  
Lake Oroville Boat Ramps
The Lime Saddle Boat Ramp is now open for use along with Bidwell Canyon and Spillway boat ramps. Bidwell Canyon and Lime Saddle boat ramps are open 24-hours per day and the Spillway boat ramps are open from 6 a.m. to 8 p.m. daily. The Lake Oroville Marina at Lime Saddle is open 8 a.m. to 4:30 p.m. and the Bidwell Canyon Marina is open 7 a.m. to 8 p.m. The Loafer Creek boat ramps remain out of the water.
Feather River Fish Planting
Millions of fish are raised every year at the Feather River Fish Hatchery, including Chinook fall and spring run salmon, and salmon’s cousin, steelhead trout – another type of anadromous fish that migrates from their river birthplace to the ocean and back to their native river to spawn. Over the last two weeks, hatchery staff transported and released over 430,000 of the steelhead trout raised last year into the Feather River below Yuba City. Releasing the young fish further downstream improves their chances of survival by shortening their migration route to avoid predators. An additional 10,000 steelhead were also released into the Thermalito Afterbay to support that popular recreational fishery.

The Feather River Fish Hatchery is a California State Water Project facility built in the late 1960s to mitigate impacts on fish migration resulting from the construction of Oroville Dam which blocked access to spawning grounds further upstream. DWR maintains the facility and funds the hatchery operations, fish spawning, rearing, and stocking activities provided by California Department of Fish and Wildlife staff. Photos of the steelhead trout release are available on the Department of Water Resources (DWR) Pixel webpage – search ‘fish release’.

Thermalito Powerplant Update
The Department of Water Resources (DWR) Thermalito Powerplant (THPP), formally named the Ronald B. Robie Thermalito Pumping-Generating Powerplant, has returned to full service after losing operational capacity when it was damaged by fire in November 2012. The powerplant has been re-constructed with modern fire and life safety features, and the plant’s electrical protection, control, and communications systems have been fully replaced. The thousands of connections in the plant’s new systems underwent the strict and rigorous ‘interconnection’ requirements of Pacific Gas & Electric (PG&E) to safely re-connect the powerplant to the state’s electrical grid.

The THPP is one of three hydroelectric powerplants in the Oroville-Thermalito Complex, capable of generating 118 megawatts – enough to power roughly 100,000 households and adding value to the approximately 714 megawatts produced by Oroville Dam’s Edward Hyatt Powerplant. Along with the Thermalito Diversion Dam Powerplant, the Oroville-Thermalito Complex is California’s State Water Project’s leading producer of clean hydro-electric power.

Oroville Recreation Advisory Committee to Meet
The Oroville Recreation Advisory Committee (ORAC) met on Feb. 5. Due to the COVID-19 pandemic, the meeting was not open to the public to protect public health. ORAC was established by the Federal Energy Regulatory Commission (FERC) to review and provide recommendations regarding the Department of Water Resources (DWR) Recreation Plan for the Lake Oroville State Recreation Area. To obtain a summary of the meeting, send a request to oroville@water.ca.gov.
Wildfire Impacts on Water Quality         
In late 2020, several members of the multi-agency “Watershed Working Group”, led by the California Governor’s Office of Emergency Services (CalOES), conducted targeted monitoring of rivers, lakes, and other surface waters in the North Complex burn area and downstream. The Central Valley Regional Water Quality Control Board (Water Board), California Department of Water Resources (DWR), and the California Department of Fish and Wildlife (CDFW) collected and tested samples of surface waters throughout the North Complex Fire’s burn scar in Butte and Plumas counties. Results revealed some contaminant levels are elevated, but are lower than anticipated. The Water Board issued a news release today stating these elevated results are not impacting drinking water treatment facilities nor the quality of drinking water.

While major wildfires often lead to subsequent water quality challenges in lakes, streams and other waterways, the lower than expected levels of contaminants could be linked to the relatively dry winter months in 2020. Water testing will continue and the Watershed Working Group will report results in the weeks ahead. The Water Board will alert the public if results show water quality may be further impacted.

Wildfire Impacts on Water Quality         
In late 2020, several members of the multi-agency “Watershed Working Group”, led by the California Governor’s Office of Emergency Services (CalOES), conducted targeted monitoring of rivers, lakes, and other surface waters in the North Complex burn area and downstream. The Central Valley Regional Water Quality Control Board (Water Board), California Department of Water Resources (DWR), and the California Department of Fish and Wildlife (CDFW) collected and tested samples of surface waters throughout the North Complex Fire’s burn scar in Butte and Plumas counties. Results revealed some contaminant levels are elevated, but are lower than anticipated. The Water Board issued a news release today stating these elevated results are not impacting drinking water treatment facilities nor the quality of drinking water.

While major wildfires often lead to subsequent water quality challenges in lakes, streams and other waterways, the lower than expected levels of contaminants could be linked to the relatively dry winter months in 2020. Water testing will continue and the Watershed Working Group will report results in the weeks ahead. The Water Board will alert the public if results show water quality may be further impacted.

Flood After Fire Preparedness
Risks for mud and debris flows into communities and homes downslope of areas burned by wildfire are increased when precipitation events occur. In normal conditions, trees, shrubs, grass, and other protective groundcover allow rainfall to infiltrate into the soil. In addition to removing vegetation, a wildfire’s extreme heat can bake the soil, further preventing water penetration. Due to these changes, even a small storm system in burn scar areas can cause flash flooding and lead to mud and debris flows.

It is important to stay alert and be prepared before flooding occurs. Being ready means knowing when to evacuate. Get the latest information from the National Weather Service at www.weather.gov – just enter your city or zip code. More information on flood after fire can be found in this short video as well as on the DWR website. 
Oroville Recreation Advisory Committee to Meet
The Oroville Recreation Advisory Committee (ORAC) will meet Feb. 5. Due to the COVID-19 pandemic, the meeting will not be open to the public to protect public health. ORAC was established by the Federal Energy Regulatory Commission (FERC) to review and provide recommendations regarding the DWR Recreation Plan for the Lake Oroville State Recreation Area. To obtain a summary of the meeting, send a request to oroville@water.ca.gov.

California Conservation Corps Constructs Fish Habitat from Recycled Christmas Trees
DWR and the California Conservation Corps (CCC) have completed constructing fish habitat structures at Lake Oroville and the Thermalito Afterbay using over 950 recycled Christmas trees. The trees were collected by Chico Boy Scout Troop 2 and the Biggs 4-H Club and delivered to DWR by Recology, a local waste management company.

The habitat structures of stacked Christmas trees were created by threading wire cable through CCC-drilled holes in the trunks and anchoring the cable to the lakebed in various locations. Anchoring the trees allows them to stay submerged as the lake’s water level rises from winter storm and snowmelt inflows.

The structures provide juvenile fish safe refuge, improving fisheries and recreational fishing opportunities. For over 25 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. Find more information on the project at DWR Updates.

Current Lake Operations
The elevation of Oroville’s reservoir is about 697 feet elevation and storage is about 1.23 million acre-feet, 35 percent of average. Currently, in the Northern Sierra Basin, rainfall is below average, at 51 percent of normal for this time of year and snowpack is also below average at 64 percent of normal. Precipitation is forecast through the middle of the first week of February with dry conditions afterwards.

The total releases to the Feather River continues to be at 1,250 cfs to conserve storage in Lake Oroville. The Feather River flows consist of 800 cfs down the Low Flow Channel through the City of Oroville, and 450 cfs from the Thermalito Afterbay Outlet (Outlet) for a total of 1,250 cfs for the Feather River’s high flow channel downstream of the Outlet. Additional flow and visible increases in the elevation of the Feather River are due to significant runoff from this week’s storms.

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”.

Construction of Loafer Point Stage 2 Boat Ramps
Constructing low water access boat ramp lanes in a reservoir presents unique challenges as contractors face rising water levels from winter precipitation and construction of the Loafer Point Stage 2 boat ramp project is no exception. Fortunately, the project to build six new boat launch lanes and 180 trailered parking spaces to allow boaters to enter the lake when lake elevations are below elevation 805 feet is making progress. This year’s low lake levels provided DWR the opportunity to build the ramp down to elevation 703 feet and the contractor has already placed over 115 feet of concrete. When the lake levels are lower due to dry years in the future, the ramp will be extended to lower lake elevations.

The Loafer Point Stage 2 project will be adjacent to an existing Loafer Creek Recreation Day Use Area and Campground, rounding out a full-service recreation destination with nearby trails, campgrounds, boating, and marina. Additionally, immediate access to the wide-open waters of Lake Oroville will make Loafer Point a popular boat launching location. The recently completed Loafer Point Stage 1 boat launch added three new boat launch lanes from a full lake down to 799 feet, a new parking area, and new restroom facilities.

Snow Survey
The Department of Water Resources (DWR) conducted its first Phillips Station snow survey on Dec. 30. The manual survey recorded 30.5 inches of snow depth and a snow water equivalent of 10.5 inches, which is 93 percent of the Jan. 1 average for this location. The snow water equivalent (SWE) measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. On average, the Sierra Snowpack supplies about 30 percent of California’s water needs through spring snowmelt which feeds rivers and eventually reservoirs and aqueducts where it can be stored for use throughout the dry season. Statewide monitoring stations indicate that the state’s snowpack SWE is five inches, or 52 percent of the December 30 average.

DWR Opens Lake Oroville Low Water Launch Ramp
The Department of Water Resources (DWR) opened a temporary low water boat launch site at the Oroville Dam Spillway Boat Ramp area. This facility is currently the only way to launch trailered boats until 3:30 p.m. Thursday, Dec. 24.

Declining water levels at Lake Oroville have temporarily placed the Loafer Creek, Lime Saddle, and Spillway boat ramps out of service. DWR construction at the Bidwell Canyon Boat Ramp area has temporarily prevented access to the lake at this location and the Spillway low water launch facility was opened to provide for boat launching and recovery until construction is completed at Bidwell Canyon.

This gravel launch site will be available for use only by 4-wheel drive vehicles with experienced drivers. Signage will be placed to direct drivers to the appropriate launch and parking facilities. The Bidwell Canyon boat ramp is anticipated to open at 3:30 p.m. Thursday, Dec. 24, however construction-related complications could delay this schedule. Launching conditions are subject to change due to weather, changing lake levels, or other variables. For information, contact DWR at 916-213-5205.

Tour the Feather River Fish Hatchery
The Chinook salmon spawning season is over and thousands of students, along with many adults, missed their annual visit to the Feather River Fish Hatchery which remains closed due to the COVID-19 pandemic. DWR Lake Oroville Visitors Center Tour Guides conduct well over one hundred tours between September and November for elementary and junior high school classes. To continue this valuable education for 2020, DWR developed a virtual tour teachers can share with their students.

The “tour” begins at the hatchery fish barrier dam and moves throughout the hatchery as it follows the route of a real-world tour, including a visit to the processing room where hatchery technicians remove the eggs and milt from the salmon and move the fertilized eggs to the incubator room. 

The video also shows the technicians as they take scale samples and measurements. The virtual tour concludes with a visit to the rearing channels where nearly half a million steelhead fry are kept until they are big enough to be released back into the river. The video has been distributed to teachers in the greater Butte County area and is available on DWR’s YouTube channel.

DWR Opens Lake Oroville Low Water Launch Ramp
The Department of Water Resources (DWR), in conjunction with the California Department of Parks and Recreation (CA Parks) and the California Highway Patrol (CHP), has opened a temporary low water boat launch site at the Oroville Dam Spillway Boat Ramp area. This facility will be the only way to launch trailered boats starting Dec. 14.

Declining water levels at Lake Oroville have temporarily placed the Loafer Creek and Lime Saddle boat ramps out of service, and by Monday, Dec. 14, the paved Spillway Boat Ramp will also be unavailable. Current DWR construction at the Bidwell Canyon Boat Ramp area will temporarily prevent access to the lake at this location starting Monday, Dec. 14. Bidwell Canyon’s Stage II boat ramp will be available from 4 p.m. Friday, Dec. 11 to midnight Sunday, Dec. 13.

Starting Dec. 14, the Spillway low water launch facility will be opened to provide for boat launching and recovery until construction is completed at the Bidwell Canyon boat ramp. This gravel launch site will be available for use only by 4-wheel drive vehicles with experienced drivers. Signage will be placed to direct drivers to the appropriate launch and parking facilities. The Bidwell Canyon boat ramp is anticipated to open between Dec. 24 and Dec. 27, however inclement weather could cause delays to this schedule. Launching conditions are subject to change due to weather, changing lake levels, or other variables. For information, contact DWR at 916-213-5205.

DWR Fuel Load Management Program
DWR has resumed Fuel Load Management Plan (FLMP) projects to reduce wildfire risk, increase public safety, and enhance forest and watershed health around Lake Oroville. Projects include work at Loafer Creek State Recreation Area to remove ladder fuels and dead and dying vegetation and thin unhealthy overstocked trees and overgrown vegetation which increases the intensity of wildfires. Previous work done in the Loafer Creek area has been identified as contributing to the slowing of the North Complex Fire as it approached Kelly Ridge, increasing firefighters’ ability to establish a secure fire line and preventing the fire from spreading forward.

The FLMP projects occur within the Oroville Facilities Federal Energy Regulatory Commission (FERC) Project boundary. The FLMP was developed and is carried out in coordination with federal, state, and local fire and resources management agencies. Since the Plan’s launch in November 2012, approximately 660 acres within the FERC project boundary have been manually thinned, re-thinned, grazed, and/or treated with prescribed fire.

DWR is in the planning stage for several fuels reduction projects in various areas within the FERC project boundary including: the Hyatt Power Plant area, Bidwell Canyon Recreation area, Canyon Drive, Lime Saddle Recreation area, Feather River Fish Hatchery, and areas within the North Complex Fire burn scar. DWR’s goal is to treat an additional 1,000 acres over the next five years.

Construction of Loafer Point Stage II Boat Ramps
Construction continues on the Loafer Point Stage 2 boat ramp project to build six new boat launch lanes and 180 trailered parking spaces, allowing boaters to enter the lake when lake elevations are below 805 feet and providing access to 695 feet if water levels allow that construction this winter. Constructing low water access boat ramp lanes in a reservoir presents unique challenges as contractors face rising water levels from winter precipitation.

The Loafer Point Stage 2 project will be adjacent to an existing Loafer Creek Recreation Day Use Area and Campground, rounding out a full-service recreation destination with nearby trails, campgrounds, boating, and marina store. Additionally, immediate access to the wide-open waters of Lake Oroville will make Loafer Point a popular boat launching location. The recently completed Loafer Point Stage 1 boat launch added three new boat launch lanes to 799 feet, a new Americans with Disabilities Act (ADA) compliant parking area, and new restroom facilities. The Loafer Creek Recreation Area remains closed to the public for fire recovery work.

DWR Conducting Salmon Carcass Survey
DWR environmental scientists have been boating up and down the Feather River from Oroville to Gridley over the past couple of months performing their annual count of chinook salmon carcasses. Formally titled the Chinook Salmon Escapement Survey, these counts are very important in estimating how many fish have returned to the Feather River for spawning.

As salmon return to the Feather River to spawn, or reproduce, it marks the end of their life cycle. But that is not the end of information they can provide. Carcasses missing their adipose fin (near the tail), means they were born at the Feather River Fish Hatchery, which also implants a coded wire tag with data that can be retrieved by the scientists. For more information on DWR’s Feather River Program’s carcass survey, as well as an informational video, visit the DWR Updates webpage. Photo: DWR scientist prepares to perform salmon carcass survey

DWR Completes Oroville Dam Safety Comprehensive Needs Assessment
DWR recently published a summary report of the Oroville Dam Safety Comprehensive Needs Assessment (CNA). The CNA was initiated in January 2018 to identify dam safety and operational needs following reconstruction of the spillways damaged in February 2017. A team of dam safety experts, engineers, consultants, and community representatives participated in the assessment which determined that the Oroville Dam Complex is safe to operate and no urgent repairs are needed.

The CNA identified several risk-reduction projects that DWR already is moving to implement, including installation of new water pressure measurement devices to improve seepage monitoring and completion of a state-of-the-art seismic stability analysis. DWR also is planning to implement recommendations to raise Parish Camp Saddle Dam by three feet, line Palermo Canal to reduce leakage and improve rock slope stability, and install new remote starter and power connections to the spillway radial gates to improve reliability. In addition, the CNA identified potential vulnerabilities that require further examination to better understand their actual risk.

Bryozoans Return to Lake Oroville
Have you seen strange orange or tan ‘blobs’ in Lake Oroville? Bryozoans are aquatic invertebrates. But instead of being a single organism like jellyfish, bryozoans are made up of thousands of individual microscopic animals called zooids, living in a colony. A single colony can grow to be 12-20 inches in diameter and many can grow close together, creating a large mass. More commonly found in lakes in the eastern United States, they have migrated via birds, winds, and other means to western lakes. They appear regularly in Lake Oroville during the late summer or early fall and can be found free-floating in the water or attached to submerged branches, ropes, or even houseboat pontoons.

Current Lake Operations
The elevation of Oroville’s reservoir is about 726 feet and storage is about 1.4 million acre-feet. This weekend expect much cooler temperatures; around a half an inch of rainfall is forecasted for the Feather River Basin. During the week of November 9, cool temperatures will continue with a chance of rain later in the week. 

The total releases to Feather River continue at 2,450 cfs to meet downstream Bay-Delta water quality and flow standards. The Feather River flows consist of 800 cfs through the Low Flow Channel adjacent to the City of Oroville, and 1,650 cfs from the Thermalito Afterbay Outlet (Outlet) for a total of 2,450 cfs for the Feather River’s high flow channel downstream of the Outlet.

October 30, 2020
Fire Impacts to Lake Oroville
The Department of Water Resources (DWR) is a member of the “Watershed Working Group” led by the California Office of Emergency Services (Cal-OES). The working group is a multi-agency team evaluating and identifying areas of concern in the Feather River watershed affected by recent wildfires. Field teams are taking action to address erosion, debris runoff, and water quality impacts. DWR’s Division of Flood Management is currently assisting California Conservation Corps members to install erosion control measures in areas of concern.

DWR water quality experts have expanded water sampling activities at Lake Oroville and continue to monitor for algal blooms and other environmental concerns. After the 2018 Camp Fire, data collected by DWR environmental scientists showed no long-term impacts to water quality in Lake Oroville.

The clearing of debris entering Lake Oroville is part of ongoing DWR maintenance of Lake Oroville. Additional work is planned to protect boaters and ensure safe operation of dam facilities. Several ancillary DWR facilities around Lake Oroville experienced fire damage. DWR staff are making repairs to the impacted facilities.

October 16, 2020
Fire Impacts to Lake Oroville
The Department of Water Resources (DWR) is a member of the post-fire task force led by the California Office of Emergency Services (Cal-OES). The task force is a multi-agency team that will evaluate and identify areas of concern in the watershed. They will coordinate and prioritize actions to address erosion, debris runoff, and water quality impacts to the watersheds impacted by wildfire.

DWR environmental scientists actively monitor Lake Oroville for water quality, algal blooms, and other environmental concerns, including wildfire impacts. After the 2018 Camp Fire, DWR installed additional monitoring stations. The data collected by DWR environmental scientists did not show long-term impacts to water quality in Lake Oroville.

As part of routine maintenance year-round, DWR takes steps to reduce erosion on the lake’s shoreline. The clearing of debris entering Lake Oroville is part of ongoing DWR maintenance of Lake Oroville to protect boaters and ensure safe operation of the dam facilities.
Oroville Recreation
The Lime Saddle and Oroville Dam Spillway boat ramps are open and the Bidwell Canyon boat launch is open on weekends while construction, expected to be completed in November, is underway. (See below for information.) Bidwell Canyon and Lake Oroville (Lime Saddle) marinas are open for normal operation under regular winter schedules. Visit the CA Parks Lake Oroville State Recreation Area (LOSRA) webpage for current information on facility status as well as current requirements to protect public health during the COVID-19 pandemic.

The Potter’s Ravine and North Fork trails near the Spillway boat launch area and trails in the Loafer Creek recreation area are closed to repair fire damage. Enterprise, Stringtown, and Foreman Creek boat ramp areas, the Loafer Creek Recreation Area, and Lake Oroville Visitor Center also remain closed. Current recreation facility information can also be found on DWR’s Lake Oroville Recreation webpage. Information for the Oroville Wildlife Area, including the Thermalito Afterbay, is available on the CA Department of Fish and Wildlife webpage.
Bidwell Canyon Boat Ramp Closed Weekdays for Facility Improvements
The Bidwell Canyon boat ramp will be closed weekdays, Monday through Friday, from Oct. 5 to Nov. 18 to continue construction started in 2018 to expand the parking area and provide two additional boat ramp lanes to 700 feet. The boat ramp will open at 5 a.m. on Saturdays and close at midnight Sundays. Kelly Ridge and Arroyo Drive residents should anticipate large construction equipment and rock and concrete deliveries in the area.

Installation of Piezometers Completed at Oroville Dam  
Data collected from four new piezometers installed at the headworks of Oroville Dam’s main, or flood control outlet (FCO) spillway will be used to confirm drain performance, inform on-going structural modeling and analyses, and direct future improvements to the FCO structure which houses eight gates to control water flow down the spillway.

This work, completed on Oct. 5, is part of early implementation of the Oroville Dam Safety Comprehensive Needs Assessment (CNA), which is focused on identifying priorities and appropriate solutions to bolster the integrity and resiliency of the Oroville Dam complex to ensure public safety. Several piezometers were originally installed in the dam over fifty years ago which, as anticipated, have since stopped functioning. DWR continues its work to install additional instrumentation throughout the facility to provide ongoing, real-time data to DWR engineers, including eight new piezometers installed earlier this year at the base of Oroville Dam.
