Feather River Fish Hatchery Fall-run Chinook salmon spawning operations have successfully concluded at the Feather River Fish Hatchery. The hatchery’s spawning process collects eggs from female fish and milt from male fish to fertilize the eggs. After fertilization, the eggs are placed in incubators to develop. After the salmon reach the “fry” stage (juvenile salmon), they are transferred to long ponds filled with Feather River water called “raceways” to grow until they are large enough to be returned to the river or planted in locations further downstream to avoid predators. Steelhead (a cousin of Chinook salmon) spawning operations will begin in late December. Earlier this year, the hatchery released more than 1 million spring-run salmon, 6.3 million fall-run salmon, and nearly 450,000 steelhead in the Feather River and other locations and planted over 100,000 inland salmon this spring in Lake Oroville. The Feather River Fish Hatchery is a California State Water Project facility owned and maintained by the Department of Water Resources (DWR), which funds hatchery operations. The California Department of Fish and Wildlife (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.

Please use caution and respect the construction fencing and safety signage when visiting Oroville Dam or the Spillway Boat Ramp.  Lake Oroville Boating The temporary, single-lane boat ramp at Oroville Dam’s Spillway Boat Ramp area is open for public use from 6 a.m. to 8 p.m. to launch trailered boats. Vehicles within the parking lot at closing time will be locked in until the next morning. The water depth covering the bottom of Bidwell Canyon paved Stage III boat ramp is still not deep enough to provide safe boat launching. Lake levels have and are expected to continue to increase as a result because of recent and forecasted rainfall events. Boaters are advised to park vehicles and trailers well above lake level when boating on the lake. The spillway auxiliary ramp has a gravel surface which becomes slippery when wet, especially during times of heavy usage. To maintain the integrity of the ramp, drivers must avoid tire spin by placing vehicles in 4-wheel drive and accelerating slowly when exiting the ramp, with or without a loaded trailer. As weather conditions and lake levels change, the fitness of the ramp for continued use will be regularly assessed. Boaters on the lake are advised to be aware of unexpected shallow water and obstruction hazards such as partially submerged trees exposed by low lake levels. State Parks has issued an order for the Lake Oroville State Recreation Area (LOSRA) that boating access on Lake Oroville is not permitted starting one-half hour after sunset and ending one-half hour before sunrise due to navigational hazards. Houseboats and vessels remaining on the water must be on their mooring ball or in a slip during hours of lake closure. Additional information can be obtained by calling State Parks at (530) 538-2200. All access to boats and houseboats at both Bidwell Canyon and Lime Saddle Marinas must be coordinated through the marina prior to arrival by calling (530)589-9175 or by utilizing the shuttle service at Bidwell Canyon Marina.

Flooding risks are present across California and especially near areas impacted by past and recent wildfires. Make sure you are prepared for flood events through these three steps:
Visit DWR’s Flood Preparedness webpage for information about keeping you, your loved ones, and community safe. Current Lake Operations The elevation of Oroville’s reservoir is about 662 feet elevation and storage is about 990,000-acre-feet, which is 28 percent of its total capacity and 55 percent of historical average. Since Oct. 18, Lake Oroville has seen a rise of about 33 feet and an increase in storage of about 200 thousand acre-feet with continuing incremental storage gains. The current forecast indicates precipitation on Saturday and early next week, up to 1.4 inches of rain, with temperatures ranging in the low 60s to high-50s, then warming up later in the week to the high-60s to low-70s. Since Oct. 25, DWR has decreased releases, and as of Nov. 4, total flows to the Feather River are at 950 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 300 cfs. Releases are assessed daily and continued release reductions are expected to conserve water. 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”.

October 29, 2021 Historic Storm Impacts The recent series of atmospheric river (AR) storms, including a Category 5 AR Oct. 24-25 that set record-breaking rainfall totals across Northern California, dropped over 10 inches of rain in the Feather River watershed that supplies the Lake Oroville Reservoir. The reservoir’s elevation on Friday, Oct. 22 was 629 feet and by Wednesday, Oct. 27 had reached 658 feet, an increase of 29 feet. Inflows from the storm continue to arrive as the region prepares for another storm, making this one of the wettest Octobers on record. Lake Oroville’s historic low lake levels have exposed areas of the lakebed that have been underwater for decades, accumulating layers of silt that easily erode in heavy precipitation events. This type of erosion was very noticeable near the Bidwell Canyon Stage III boat ramp. The concrete boat ramp is not in any danger because it is built on a solid foundation of compacted gravel and armored along its slopes with large stones called riprap which reduce erosion impacts. Lake level rise will stop further erosion from occurring. Woody debris carried on inflows from each fork of the Feather River was about what is normally expected from heavy storms. The Department of Water Resources’ (DWR) Oroville Field Division’s Civil Maintenance crews are deploying log booms to restrict the movement of floating debris into the main body of the lake. These log booms will be repositioned over the coming months as lake elevations rise. Photo: October storm erosion at Bidwell Stage III boat ramp Oroville Recreation Advisory Committee The Oroville Recreation Advisory Committee will hold a public virtual meeting on Friday, Nov. 5 from 9 a.m. to noon. Interested persons can register for the meeting at https://ca-water-gov.zoom.us/meeting/register/tZcpd-mprTojGdFyLVFrSqQQxfBljOLERijl.

The 13-member committee is made up of representatives from state and local government, sports and recreation groups, and business and community organizations. Lakeside Access Road Construction The Lakeside Access Road project began this week. 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 (below 800 feet elevation). The new road will include two concrete traffic lanes, wide shoulders for walking and biking, guardrails, and safety signage. Additionally, the contractor will be removing and replacing deteriorating asphalt from the Stage I Spillway Boat Ramp. Visitors to Oroville Dam can expect to see large construction equipment and material deliveries in the area through January as the contractor works to complete the project. Please use caution and respect the construction fencing and safety signage when visiting Oroville Dam or the Spillway Boat Ramp.  Water Quality Working Group In late fall of 2020, Butte County, the Governor’s Office of Emergency Services (CalOES), Department of Water Resources (DWR), State Water Resources Control Board and Regional Water Quality Control Boards (Water Boards), California Department of Fish and Wildlife, California Department of Parks and Recreation, and local water purveyors formed the North Complex Watershed Working Group to monitor and evaluate watershed and infrastructure response to the North Complex wildfire from 2020. This working group has expanded its scope to include impacts from the 2021 Dixie Fire and will now be called the Feather River Watershed Working Group (Working Group). Additional partner agencies, including affected counties such as Plumas County, have joined others from local, state, and federal levels to coordinate regarding water quality and infrastructure impacts in the watershed. Members of the Working Group also provide technical guidance and expertise to local agencies and partners on water quality monitoring and protections in the post-fire environment. The Working Group is preparing for the upcoming rainy season and currently meets bi-weekly, with the option to increase meeting frequency as the season progresses. The Working Group will continue to provide the public with informational updates on watershed conditions and water quality testing results as they become available. The summary of last year’s findings can be found on the Water Boards’ July 8, 2021 news release.

More than seven million California residents are at risk of flooding, and many don’t realize it. Flooding happens throughout the state; every California county has received a flood-related emergency declaration in the past 20 years and flood events during and after drought conditions are not uncommon. Make sure you are prepared for flood events through these three steps:
This year, many communities are at additional risk for flooding because of wildfire damage as evidenced by this week’s National Weather Service’s Flash Flood Watch for the North Complex and Dixie wildfire burn scar areas. Wildfires dramatically change the landscape and ground conditions in a watershed. Natural, unburned vegetation and soil normally act as a sponge during a rainfall event. However, the heat from a fire can bake the ground, creating a surface that will not absorb water and can increase the speed with which water flows off the slope, leading to damaging, and sometimes catastrophic, mud and debris flows. These conditions can be present for years after a wildfire. Visit DWR’s Flood Preparedness webpage for information about keeping you, your loved ones, and community safe. Current Lake Operations The elevation of Oroville’s reservoir is about 659 feet elevation and storage is about 970,000-acre-feet, which is 27 percent of its total capacity and 53 percent of historical average. Water year 2022, which started on Oct. 1 and ends on Sept. 31, 2022, started off with a series of atmospheric river storms making landfall in northern California. So far, Lake Oroville has seen a rise of about 30 feet and an increase in storage of 170 thousand acre-feet with continuing incremental storage gains. The current forecast indicates dry conditions over the weekend and chance of rain, up to 0.5 inch during the week of Nov. 1 with temperatures in the low to mid-60’s. To manage increased flows in the Oroville Complex, on Oct. 24, DWR increased the total releases from the Thermalito Afterbay Outlet to 2,500 cubic feet per second (cfs) for a total of 3,150 cfs total to the Feather River. Beginning on Oct. 25, DWR has been ramping down total releases to the Feather River. As of Oct. 29, total flows to the Feather River are 1,500 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 and continued release reductions are expected to conserve water. 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”.

October 22, 2021 Flood Preparedness Week More than seven million California residents are at risk of flooding, and many don’t realize it. Flooding happens throughout the state; every California county has received a flood-related emergency declaration in the past 20 years and flood events during and after drought conditions are not uncommon. Make sure you are prepared for flood events through these three steps:
This year, many communities are at additional risk for flooding because of wildfire damage as evidenced by this week’s National Weather Service’s Flash Flood Watch for the North Complex and Dixie wildfire burn scar areas. Wildfires dramatically change the landscape and ground conditions in a watershed. Natural, unburned vegetation and soil normally act as a sponge during a rainfall event. However, the heat from a fire can bake the ground, creating a surface that will not absorb water and can increase the speed with which water flows off the slope, leading to damaging, and sometimes catastrophic, mud and debris flows. These conditions can be present for years after a wildfire. Visit DWR’s Flood Preparedness webpage for information about keeping you, your loved ones, and community safe. Water Quality Working Group In late fall of 2020, Butte County, the Governor’s Office of Emergency Services (CalOES), Department of Water Resources (DWR), State Water Resources Control Board and Regional Water Quality Control Boards (Water Boards), California Department of Fish and Wildlife, California Department of Parks and Recreation, and local water purveyors formed the North Complex Watershed Working Group to monitor and evaluate watershed and infrastructure response to the North Complex wildfire from 2020. This working group has expanded its scope to include impacts from the 2021 Dixie Fire and will now be called the Feather River Watershed Working Group (Working Group). Additional partner agencies, including affected counties such as Plumas County, have joined others from local, state, and federal levels to coordinate regarding water quality and infrastructure impacts in the watershed. Members of the Working Group also provide technical guidance and expertise to local agencies and partners on water quality monitoring and protections in the post-fire environment. The Working Group is preparing for the upcoming rainy season and currently meets bi-weekly, with the option to increase meeting frequency as the season progresses. The Working Group will continue to provide the public with informational updates on watershed conditions and water quality testing results as they become available. The summary of last year’s findings can be found on the Water Boards’ July 8, 2021 news release.  Lake Oroville Boating The temporary, single-lane boat ramp at Oroville Dam’s Spillway Boat Ramp area has reopened for public use from 6 a.m. to 8 p.m. to launch trailered boats. Vehicles within the parking lot at closing time will be locked in until the next morning. Lake levels are expected to substantially increase as a result of weekend storms. Boaters are advised to park vehicles and trailers well above lake level when boating on the lake. The spillway auxiliary ramp has a gravel surface which becomes slippery when wet, especially during times of heavy usage. To maintain the integrity of the ramp, drivers must avoid tire spin by placing vehicles in 4-wheel drive and accelerating slowly when exiting the ramp, with or without a loaded trailer. As weather conditions and lake levels change, the fitness of the ramp for continued use will be regularly assessed. Boaters on the lake are advised to be aware of unexpected shallow water and obstruction hazards such as partially submerged trees now that lake levels have reached historic lows. State Parks has issued an order for the Lake Oroville State Recreation Area (LOSRA) that boating access on Lake Oroville is not permitted starting one-half hour after sunset and ending one-half hour before sunrise due to navigational hazards. Houseboats and vessels remaining on the water must be on their mooring ball or in a slip during hours of lake closure. Additional information can be obtained by calling State Parks at (530) 538-2200. All access to boats and houseboats at both Bidwell Canyon and Lime Saddle Marinas must be coordinated through the marina prior to arrival by calling 530-589-9175 or by utilizing the shuttle service at Bidwell Canyon Marina. Shuttle services to Lime Saddle Marina is not being provided at this time. The Thermalito Afterbay and Thermalito South Forebay continue to be open to power boating.

Crews from the Butte Fire Center and CAL FIRE are taking advantage of wet weather to start burning the piles of brush, burnt vegetation, and hazard trees that was removed last season in the North Complex wildfire burn scar. Smoke from the burn piles may be visible from the Oro Quincy Highway (Highway 162). The CAL FIRE news release is available here. Through DWR’s Fuel Load Management Program, DWR partners with CAL FIRE, the California Conservation Corps, Butte County Sheriff Office, Butte County Fire Safe Council, and others on vegetation management projects to reduce fire risk, increase public safety, protect infrastructure, and enhance forest health in areas around Lake Oroville. Approximately 840 acres have been manually thinned, re-thinned, grazed, and/or treated with prescribed fire since November 2012. DWR’s goal is to treat 150 acres this season. Photo: CAL FIRE pile burning project  Oroville Recreation Numerous Day Use Area (DUA) facilities with picnic tables and restrooms at Lake Oroville State Recreation Area (LOSRA) are open 8 a.m. to sunset. Bidwell, Lime Saddle, and Loafer Creek recreation areas are open 24 hours. The Oroville Dam Crest Road across Oroville Dam is available 5 a.m. to 11 p.m. daily with the Spillway trailhead and boat launch open from 6 a.m. to 8 p.m. The top of the dam is open to pedestrians and bicyclists 24-hours a day.

Chinook salmon are completing their life cycle and returning home to the Feather River to lay eggs for the next generation of salmon. The Feather River Fish Hatchery’s fish ladder is open and hatchery spawning operations – which enable millions of Chinook salmon to be released to the river every spring – are underway. To protect public health during the COVID-19 pandemic, the hatchery continues to be closed. Visitors can still enjoy seeing salmon climb the fish ladder at the Underwater Viewing Area and Overlook near the Feather River’s Fish Diversion Dam north of the hatchery. The public is urged to maintain physical distancing and abide by Butte County requirements for mask-wearing to protect personal health and the health of others. Photo: Visitors watch salmon jump at the Feather River Fish Hatchery Overlook near the Fish Diversion Dam Loafer Point Stage II Boat Ramp Extension Construction work to extend three lanes of the Loafer Point Stage II boat ramp farther into the dry lakebed of Lake Oroville continues. Earthwork and ramp construction will continue until winter precipitation causes lake levels to rise. The existing Stage II facility was completed this spring, providing six new boat launch lanes extending to elevation 702 feet and 180 trailered parking spaces. The new launch lanes are anticipated to go as low as 640 feet elevation. Visitors and nearby residents are reminded to be aware of construction equipment and vehicles, including those entering and exiting the Loafer Creek recreation area at Oro-Quincy Highway. Current Lake Operations The elevation of Oroville’s reservoir is about 629 feet elevation and storage is about 792,000-acre-feet, which is 22 percent of its total capacity and 37 percent of historical average. Water year 2022 is starting off with a series of atmospheric river storms making landfall in northern California over the next six days. The Feather River watershed is forecasted to see up to 10 inches of rain during that time. Although the storms will not be enough to end the drought conditions, they will provide much needed rainfall to the very dry Feather River watershed. Saturated soils in the watershed will result in higher runoff into streams, rivers, and reservoirs and is anticipated to result in an approximately 20-feet increase in Lake Oroville’s lake elevation. Visitors are advised to park well above lake level when visiting or boating on the lake. Total flows to the Feather River are 1,250 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 600 cfs. Total releases to the Feather River 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”.

October 8, 2021 Loafer Point Stage II Boat Ramp Extension Historic low lake levels at Lake Oroville are allowing DWR to extend three lanes of the Loafer Point Stage II boat ramp farther into the dry lakebed. Work to create the new boat launch lanes began this week and will continue until winter precipitation causes lake levels to rise. The existing Stage II facility was completed this spring, providing six new boat launch lanes extending to elevation 702 feet and 180 trailered parking spaces. The Loafer Point Stage II facility is 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 makes Loafer Point a popular boat launching location. The Loafer Point Stage I boat launch facility, completed in 2020, added three new boat launch lanes from a full lake down to 799 feet, a new Americans with Disabilities Act (ADA) compliant parking area, and new restroom facilities. Visitors and nearby residents are reminded to be aware of construction equipment and vehicles, including those entering and exiting the Loafer Creek recreation area at Oro-Quincy Highway. Photo: Loafer Point Stage II Boat Ramp (July 2021)  Fuel Load Management Continues Fuel reduction hand crews and heavy equipment operators from Butte Fire Center and CAL FIRE have returned to the Loafer Creek Recreation Area. Crews will be cutting, chipping, and piling burnt vegetation and hazard trees within the North Complex burn scar. Piles will be burned later this season when weather conditions are favorable. Heavy equipment and crews may be visible from Highway 162. Crews will also be prepping previously treated areas throughout Loafer Creek for a possible prescribed burn later this season. The Department of Water Resources (DWR), in partnership with California Conservation Corps and Butte County Sheriff Office, is developing plans for various fuel reduction projects throughout the Lake Oroville State Recreation Area (LOSRA). When crews are available, they will hand cut and chip prioritized overgrown vegetative areas within the Federal Energy Regulatory Commission (FERC) project boundary. Areas of concern are the Highway 162 corridor, Kelly Ridge area, the Feather River Fish Hatchery, LOSRA, and nearby infrastructure. The DWR Fuel Load Management Plan (FLMP) goal is to reduce wildfire risk and increase public safety around the FERC project boundary including Lake Oroville. With help from area partners, approximately 840 acres have been manually thinned, re-thinned, grazed, and/or treated with prescribed fire since November 2012. DWR’s goal is to treat 150 acres this season.

Bryozoans are freshwater, aquatic invertebrates. There are nearly 5,000 species of bryozoans found throughout the world, and the majority are marine animals. Instead of being a single organism like a jellyfish, bryozoans are made up of thousands of individual microscopic animals called zooids, living in a colony. A single colony will vary in size from approximately 12 to 20 inches but some can grow bigger in diameter. These jelly-like colonies can be found attached to submerged branches, rocks, ropes, and even on houseboat pontoons and motors. They typically appear during the summer and fall months when lake levels are low. Freshwater bryozoans are harmless and non-toxic, though they can occasionally clog underwater objects. Photo: Bryozoan colonies are now visible at Lake Oroville Palermo Tunnel Bulkhead Project DWR engineers and contractors are working to re-install a refurbished bulkhead (controls inflow of water) at the submerged Palermo Tunnel Intake Structure in Lake Oroville next week. A frame and pulley system to make future installations easier will also be installed. The work will be done from a barge on the lake positioned near the Hyatt Powerplant intake structures. Cranes are being used to assemble the barge near Oroville Dam’s Spillway Boat Ramp area over the next couple of weeks. Scuba dive crews and remotely operated vehicle work to install the bulkhead is scheduled for early November. The Palermo Tunnel conveys water from Lake Oroville to the Palermo Canal, a source of water for the South Feather Water and Power Agency, which distributes water to the communities of Oroville, Palermo and Bangor.

Over 150 Acres Treated Around Lake Oroville This Season During the 2020-2021 season, DWR partnered with CAL FIRE, CA Conservation Corps (CCC), Department of Parks and Recreation (DPR), Butte County Fire Safe Council (BCFSC), and Butte County Sheriff Office (BCSO) to treat approximately 155 acres within the Federal Energy Regulatory Commission (FERC) project boundary around DWR’s Oroville facilities. A variety of fuel load treatments were successfully utilized including mastication, thinning, chipping, piling, weed eating, and grazing. Areas were treated around Bidwell Canyon and Loafer Creek, along with areas at Lakeland Blvd., Old Ferry Road, and the Feather River Fish Hatchery in Oroville. At Loafer Creek within the North Complex wildfire burn scar, CAL FIRE, CCC, and BCSO crews masticated, hand thinned, piled, and chipped approximately 60 acres of burnt vegetation. Treatment was completed along the Roy Rogers trail, access roads, around seasonal drainages, and along the Highway 162 corridor to increase public safety. Piles will be burnt this winter when crews are available and weather is favorable. DWR has temporarily paused Fuel Load Management Plan (FLMP) projects as wildfires throughout California are using available fuels reduction crews. As fire seasons grow longer, the FLMP season, which previously began in September, now runs from December to May -- after fire crews stop fighting fires and before the dry weather returns. Planning for the 2021-2022 season includes defining and scoping site-specific projects, defining and securing permits and approvals, securing funding, and contracting for the work. Emphasis will be given to areas that have been previously treated in order to manage regrowth, removing burnt trees and vegetation within the burn scar, and treating overgrown areas around the FERC project boundary. DWR’s goal is to treat and/or re-treat 1,000 acres over the next five years. Photo: Before and after FLMP treatment near Highway 162  Oroville Recreation

Oroville Wildlife Area Habitat Project The season is ending for the sunflowers and safflowers planted this spring on 60 acres of the Oroville Wildlife Area (OWA) near the Thermalito Afterbay to provide food (forage), shelter, and nesting cover for migrating and native birds. Their stalks and flowers are withered and dry, but their nutritious seeds are plentiful, providing welcome energy to birds migrating the Pacific Flyway and those calling the Sacramento Valley their home. This is the time of year when staff from the California Department of Fish and Wildlife (CDFW) mow down the dried flowers, leaving behind acres of seeds and the natural mulch of stems and leaves to nourish and strengthen the soil for next year’s crops. CDFW staff manage the 11,000-acre OWA for the Department of Water Resources (DWR) and farm over 300 acres of grains, grasses, and flowering plants yearly to augment the area’s food supply and add diversity to the area’s wildlife habitat. Learn more about this habitat project on the DWR Updates webpage.

Hand launching of small boats such as canoes or kayaks is permitted. As lake levels drop, the condition of the ramp continues to be reassessed for future use. The Bidwell Canyon Marina remains open and is providing shuttle service to boat owners from 8 a.m. until sundown. Trees, stumps, and landforms are surfacing due to low lake elevations, creating navigational hazards. Boating access on Lake Oroville is not permitted starting one-half hour after sunset and ending one-half hour before sunrise. Houseboats and vessels remaining on the water must be on their mooring ball or in a slip during hours of lake closure. Additional information can be obtained by calling State Parks at (530) 538-2200. Boaters are reminded that low lake levels bring new boating hazards, including tree stumps and snags, and newly emerging outcrops. Power boats are allowed on the Thermalito South Forebay as well as the Thermalito Afterbay. A 5-miles per hour speed limit for all boats is enforced on the Afterbay north of the Highway 162 bridge and near the brood ponds on the east side of the reservoir. No motorized boating is allowed in the Thermalito North Forebay. The Monument Hill facility at Thermalito Afterbay provides boat ramp access, restrooms, a picnic area, and a swim beach. The Thermalito South Forebay facility has a two-lane boat ramp, parking, restroom, picnic tables, BBQs, shade trees, and a fish cleaning station.

Photo: Swim beach at the Thermalito North Forebay Cold Water Temperatures Water temperatures in the Feather River and the Thermalito Diversion Pool, Forebay, and Afterbay continue to range between 48 and 58 degrees as very cold water from the bottom of Lake Oroville is released through Oroville Dam’s River Valve Outlet System (RVOS). Persons recreating on these waterbodies are advised to wear life jackets. Entering cold water on hot summer days can result in ‘cold water shock’, causing breathing difficulties as well as changes in heart rate and blood pressure and can be life threatening, especially without a life jacket to help you stay afloat. Find cold-water safety tips at the National Weather Service’s Safety webpage.  Blue Green Algae Monitoring
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, the Thermalito Forebay, or the Thermalito Afterbay. Water samples are taken at various locations regularly from Memorial Day through Labor Day. To learn more about HABs, or to report a HAB visit the Water Board’s website. Photo: Collecting algae samples for testing - Lake Oroville Drought Information DWR has created a “Drought” webpage where definitions, historical trends, current information, and maps of California’s water systems can be found. Links to resources, DWR activities, research, and data are available. Read about how heatwaves are impacting drought conditions on the DWR Updates webpage. The State of California recently launched a website drought.ca.gov. This website will serve as the State’s primary location for public drought news and information.

August 13, 2021 Cold Water Temperatures Current releases to the Feather River from Oroville Dam’s River Valve Outlet System (RVOS), which draws water from the deepest part of Lake Oroville, has resulted in cold water temperatures in the Feather River and the Thermalito Diversion Pool, Forebay, and Afterbay. Water temperatures are ranging between 48 and 58 degrees. Persons recreating on the Feather River and other waterbodies this summer are advised to wear life jackets. Entering cold water on hot summer days, called ‘cold water shock’, can cause breathing difficulties as well as changes in heart rate and blood pressure. Unplanned immersion, such as from a boat, kayak, or raft, or from jumping into the water from a beach, can be life-threatening, especially without a life jacket to help you stay afloat. Find cold-water safety tips at the National Weather Service’s Safety webpage.

Lake Oroville Historic Water Levels Climate change-induced early warm temperatures and extremely dry soils dramatically reduced expected runoff into rivers and reservoirs this spring. Combined with the past two years being the driest two-year period since 1976-1977, water levels at Lake Oroville reached historic lows this past week, falling below the previous low water elevation of 645 feet set in September 1977. The Lake Oroville Storage Forecast Chart can be found on the State Water Project Operations and Maintenance website.  Hyatt Powerplant On August 5, DWR State Water Project operations managers took the Hyatt Powerplant at Lake Oroville offline due to falling lake levels. This is the first time Hyatt Powerplant has gone offline as a result of low lake levels. However, DWR anticipated this moment, and the state has planned for its loss in both water and grid management. DWR has been in regular communication about the status of Hyatt Powerplant with the California Independent Service Operator (CAISO) and the California Energy Commission and steps have been taken in anticipation of the loss of power generation. DWR will continue to focus on reservoir operations and water storage management at Lake Oroville to preserve as much water in storage as possible. DWR will use the River Valve Outlet System to release some water from the base of Oroville Dam to maintain river temperature requirements and outflows to the Feather River.
