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.

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.

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.

Trail Closure at Loafer Creek
A one-mile portion of the Roy Rogers Trail in the Loafer Creek Recreation Area will be closed Monday through Friday starting March 22 and extending to April 30. The four-mile equestrian and hiking trail will be fully open Saturdays and Sundays only.

The Department of Water Resources (DWR) and California State Parks (CA Parks) are partnering with CAL FIRE’s Vegetation Management Program to clear hazard trees and fire-prone underbrush from the North Complex Wildfire burn scar in the Loafer Creek Recreation Area. CAL FIRE work crews will hand cut and use heavy equipment in the northeastern portion of Loafer Creek; crews may be visible or audible to visitors in the Recreation Area.

This collaborative effort to aid in recovery from impacts caused by the 2020 North Complex wildfire will continue for the next several years.
Temporary Closure of Brad Freeman Trail   
A small section of the Brad Freeman Trail near the Thermalito Diversion Pool across from Oroville Dam’s main spillway will be closed Monday, March 22 through Thursday, March 25 for electrical work. Signage directing trail users to a temporary trail around the closure have been installed. 
Temporary Closure Protects Eaglet
A section of the Wyandotte Campground in the Plumas National Forest is temporarily closed to protect a bald eagle nesting territory in the vicinity of Little Grass Valley Reservoir northeast of Oroville. The remainder of the campground is not affected by the closure which is in effect until July 15, 2021.

The closure has been in effect for almost two decades and has helped a bald eagle pair to successfully nest and raise young, contributing to the sustained recovery for this species. Bald eagles are particularly sensitive to disturbances during their nesting phase.

Information about the closure may be found on the U.S. Forest Service website at https://www.fs.usda.gov/alerts/plumas/alerts-notices.

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. 

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).

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.

Monument Hill Facility Closure
The Monument Hill Boat Ramp and Day Use Area’s boat ramp and beach on the Thermalito Afterbay, off Highway 162 near State Route 99, will be closed March 3 and March 4 for maintenance. DWR will be improving the facilities by replacing eroded sand on the beach and addressing issues with the boarding float at the boat launch.

The nearby Wilbur Road Boat Ramp facility will be available for boat launching into the Thermalito Afterbay. Additionally, the Car-top Boat Ramp on Larkin Road remains open. The public is reminded of the 5-miles per hour boating speed limit on the portion of the Thermalito Afterbay north of the Highway 162 bridge.

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

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.

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
The California Department of Parks and Recreation (CA Parks), in compliance with the modification for the Greater Sacramento Region’s COVID-19 public safety restrictions, has opened Lake Oroville State Recreation Area (LOSRA) campgrounds at Bidwell Canyon, Loafer Creek, including the Equestrian Campground, and the Lime Saddle Campground. Enroute camping at the North Forebay and Spillway facilities is also permitted. Group camping remains closed. Reservation capability does not open until April so camping sites are allocated on a ‘first come-first serve’ basis.

The Potters Ravine and North Fork trails, damaged by the August 2020 Potters Fire, are also now open for use. CA Parks encourages users to remain on the trails and assessments by CA Parks staff of trail safety will continue through the winter. Additionally, day use facilities at Foreman Creek, Stringtown, and Enterprise, damaged by the September North Complex Fire, are now open to the public. The Lake Oroville Visitors Center remains closed.

Visit the California 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. Information about recreation facilities can also be found in DWR’s interactive map on the Lake Oroville Recreation webpage. For information about the Oroville Wildlife Area, including the Thermalito Afterbay, visit the California Department of Fish and Wildlife webpage.
Recreation Improvement Project Nearly Complete
Construction is nearly complete at the Bidwell Canyon Stage II Boat Ramp Project. Visitors and users can enjoy full access to the expanded, paved parking area as well as the two additional boat ramp lanes which allow launching when the lake drops as low as 705 feet elevation. Currently, boaters are using the Stage III boat ramp at Bidwell Canyon which is open 24 hours per day and provides access to elevation 665 feet.

The auxiliary gravel boat ramp at the Oroville Dam Spillway boat ramp area is now closed and users will be directed to the Bidwell Canyon boat ramps. The paved ramps at the Spillway (and other area boat launch facilities) will reopen again as lake levels rise from anticipated winter storms and place ramps back into the water.

California Conservation Corps Helps Construct Fish Habitat from Recycled Christmas Trees
The California Conservation Corps (CCC) will start constructing fish habitat structures at Lake Oroville and the Thermalito Afterbay on Jan. 20, using over 950 recycled Christmas trees collected by Chico Boy Scout Troop 2 and the Biggs 4-H Club. To create the habitat, members of the CCC team will bundle the recycled holiday trees together using a system of wire rope to anchor them in various locations on the lakebeds.

These 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. The 2021 project is anticipated to be completed by January 29.

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.

For more information on Lake Oroville’s water elevations, visit the California Data Exchange Center at https://cdec.water.ca.gov/, select the Reservoirs tab, and then Daily Reservoir Storage Summary. Lake Oroville is listed in the Feather River section.

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 Completes Oroville Dam Safety Comprehensive Needs Assessment
The Department of Water Resources (DWR) has 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. 

A description of the CNA risk-assessment process, the CNA Summary Report and links to the meetings of the Ad Hoc Group of community representatives can be found on the Comprehensive Needs Assessment webpage.

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.
