Moderate Increase in State Water Project Allocations Announced
The Department of Water Resources (DWR) announced a modest increase in forecasted State Water Project (SWP) deliveries this year due to early gains in the Sierra snowpack. DWR now expects to deliver 35 percent of requested water supplies, up from 30 percent forecasted in January, to the 29 public water agencies that serve 27 million Californians. That would translate to an additional 210,000 acre-feet of water.
“We’re hopeful that more storms this week are a sign that the wet weather will return, but there remains a chance that 2023 will be a below average water year in the northern Sierra,” said DWR Director Karla Nemeth. “Careful planning and the use of advanced forecasting tools will enable the Department to balance the needs of our communities, agriculture, and the environment should dry conditions continue this spring and into next year.”
The SWP will continue to optimize water storage in Lake Oroville to support environmental needs in the summer and allow for carryover storage for next year if the spring becomes extremely dry. Additionally, the forecasted allocation could be adjusted back down if extreme dry conditions warrant.
More information about the SWP allocations may be found in the press release.

Oroville Dam Citizens Advisory Commission
​
The California Natural Resources Agency hosted the Oroville Dam Citizens Advisory Commission meeting today at the Southside Oroville Community Center. In addition to public comment, presentations on the January storm events, Lake Oroville reservoir debris maintenance, and spillway capacity were provided.
The Citizens Advisory Commission is a forum for questions and feedback from the communities surrounding Oroville Dam. For information on the meeting, please visit https://bit.ly/OrovilleCAC. A transcript of the meeting will be available on the webpage in the coming weeks.

CHRISTMAS TREE FISH HABITAT
​
DWR, the California Conservation Corps (CCC), and the Department of Fish and Wildlife (CDFW) finished constructing fish habitat structures at Lake Oroville and the Thermalito Afterbay using almost 1,800 recycled Christmas trees. The trees were again collected by Chico Boy Scout Troop 2 and delivered free of charge to DWR by Recology, a local waste management company.
To create the habitats on Lake Oroville and the Thermalito Afterbay, members of the CCC team bundle the recycled holiday trees together and anchor them in various locations around the lakebed. At Lake Oroville near the Loafer Creek Recreation Area, 1,250 trees were assembled into 63 structures. At the Thermalito Afterbay, 541 trees were assembled into 54 structures. Anchoring the trees allows them to remain submerged, providing juvenile fish safe refuge, and improving fisheries and recreational fishing opportunities.
This is the 30th year DWR has worked with local groups to construct fish habitat structures, which is one of the longest continuously running warmwater fish habitat improvement programs in the State of California.

FUEL LOAD MANAGEMENT 
​
DWR continues vegetation management and debris cleanup activities around the Feather River Fish Hatchery to remove overgrown ladder fuels and create a more wildfire resilient landscape. In addition, CAL FIRE, Butte County Fire Department, and the California Conservation Corps (CCC) Butte Fire Center continue cutting and pile burning activities in the Loafer Creek area and along Oro Dam Boulevard East near the Hyatt Powerplant.
Over the next couple weeks, the Butte County Sheriff crew will be cutting and piling material along Canyon Drive to reduce overgrown vegetation near the community of Kelly Ridge. CAL FIRE will burn the brush piles at a later date.
DWR is implementing a Fuel Load Management Plan (FLMP) at its Oroville Facilities to reduce wildfire risk and increase public safety around Lake Oroville and surrounding communities. Vegetation management activities will continue through the spring, weather permitting. Smoke from pile burning activities will continue to be visible in the Oroville area.


Picture
OROVILLE RECREATION 
​DWR, the California Department of Parks and Recreation, and CDFW maintain over 92 miles of trails in the Oroville area. Paved trails at the Lake Oroville Visitor Center and at the North Forebay Day Use Area offer accessible trails with only slight elevation changes. Other trails, such as the Brad Freeman Trail between the Spillway Day Use Area and the Diversion Pool, offer trails with steep elevation changes to challenge hikers and mountain bikers. The Saddle Dam Trailhead has facilities for equestrians, including a large parking area to accommodate horse trailers, water troughs, and hitching posts, and easy access to trails designated for hikers and horses.
An interactive map of recreation facilities, including open boat ramps, and their permitted uses (hike, bike, horse, multi) is available on DWR’s Lake Oroville Recreation webpage. The marinas at Bidwell Canyon and Lime Saddle are open daily and provide a variety of services such as a shuttle and boat rentals.
The Lake Oroville Visitor Center is open Monday through Friday between 9 a.m. and 5 p.m. The Visitor Center offers numerous educational exhibits, a theater featuring videos about the building of Oroville Dam, walking and hiking trails, and a 47-foot-tall observation tower providing unsurpassed panoramic views.

CURRENT LAKE OPERATIONS
​
Oroville’s reservoir is about 828 feet elevation and storage is approximately 2.53 million acre-feet (MAF), which is 71 percent of its total capacity and 115 percent of the historical average. Widespread rain showers and below-average temperatures are ahead for the weekend and into next week.
The Feather River releases are currently at 950 cubic feet per second (cfs). Flows through the City of Oroville are 650 cfs with 300 cfs released from the Thermalito Afterbay Outlet (Outlet) for a total of 950 cfs downstream of the Outlet. DWR continues to assess releases to the Feather River daily.
The public can track precipitation, snow, reservoir levels, and more at the California Data Exchange Center. The Lake Oroville gage station is identified as “ORO”.

Midwinter Bald Eagle Survey
​
Environmental scientists from DWR recently participated in the National Midwinter Bald Eagle Survey on Jan. 6 and Jan. 9. This nationwide effort, coordinated by the USACE, aims to determine bald eagle distribution and identify areas of important winter habitats. This year’s official count was 176 bald eagles for the Lake Oroville Winter Roost and three at the Thermalito Complex. This is the highest count for the Lake Oroville Winter Roost since DWR began survey participation in 2003.
Lake Oroville and the Feather River area provide an ideal habitat for bald eagles. Fish are one of the eagle’s main food sources and large water bodies like Lake Oroville provide a wide variety of fish and other favorite food sources such as waterfowl, small birds, and mammals. The many trees and snags (tall dead trees) near water areas provide prime roosting and hunting locations for the bald eagles that migrate to and through the area during the winter months.


Picture
LAKESIDE ACCESS ROAD CLOSED
​
Rising reservoir levels at Lake Oroville have required the closure of the newly constructed Lakeside Access Road, which will not reopen until water levels drop back down later this year. With the road closure in effect, vehicle access to the Spillway Boat Ramp and Day Use Area will now be via Oroville Dam Crest Road.
Vehicle access to the Spillway Boat Ramp and Day Use Area is available between 6 a.m. and 8 p.m. There are three other boat ramps at Lake Oroville that are open 24 hours a day: Bidwell Canyon, Loafer Point, and Lime Saddle.
At just 60 percent of its total capacity, Lake Oroville still has ample storage to capture storm runoff while providing flood control protection for the Feather River and downstream communities. Water inflows to the reservoir during recent storms have been as high as 50,000 cubic feet per second (cfs) while outflows in the Feather River through Oroville remain at a minimum of 650 cfs. Current outflows are being used to support local water needs and maintain flood control and are not part of water deliveries to Southern California.
In addition, DWR Oroville Field Division Civil Maintenance crews are patrolling Lake Oroville daily to collect woody debris as part of normal operations during this time of year. Boaters are advised to be alert for floating debris, which is expected during high reservoir inflows.

FUEL LOAD MANAGEMENT 
​DWR continues vegetation management activities around the Oroville area to remove overgrown vegetation and create a more wildfire resilient landscape. Over the next few months, you may see crews working in various areas including Loafer Creek, Canyon Drive, along Oro Dam Blvd. East, and the Feather River Fish Hatchery. CAL FIRE, Butte County Fire Department, Butte County Sheriff’s Office, California Conservation Corps (CCC), and crews from the Butte Fire Center continue to cut, pile, chip, and pile burn as weather allows. Vegetation management activities will continue through the winter, weather permitting. Smoke from pile burning activities will continue to be visible in the Oroville area.
DWR’s Fuel Load Management Plan (FLMP) works to reduce wildfire risk and increase public safety around Lake Oroville. Previous FLMP projects in the Loafer Creek Recreation Area have been identified as contributing to the slowing of the 2020 North Complex Fire as it approached Kelly Ridge, increasing firefighters’ ability to establish a secure fire line and preventing the fire from progressing. Ongoing management of the FLMP remains a high priority for DWR and local partners.

Feather River Fish Hatchery Opens
​
The California Department of Fish and Wildlife (CDFW) announced starting April 7, they will be re-opening 21 of the 22 state fish hatcheries. The hatcheries have been closed for nearly two years during the COVID-19 pandemic. The main Feather River Fish Hatchery facility in Oroville is now open from 7:30 a.m. to 4 p.m. seven days a week. The viewing window and overlook side will continue to be open sunrise to sunset.
The Feather River Fish Hatchery (FRFH) is divided into 2 sections:
  • The first section (viewing window side) includes the fish barrier dam, observation platform, and underwater viewing window, located on the east side of Table Mountain Boulevard. The underwater viewing windows are best for viewing fish from mid-September through June. This side of the facility is open daily from sunrise to sunset.
  • The second section (main facility) includes the spawning room, hatchery, and rearing ponds located on the west side of Table Mountain Boulevard. Salmon spawning operations can be observed Monday through Friday beginning mid-September until mid-November. Steelhead spawning can be observed mid-December through mid-February. Fish are present in the rearing ponds year-round. This side of the facility is open from 7:30 a.m. to 4 p.m. daily.
Learn how the hatchery raises Chinook salmon and steelhead to support California’s salmon populations during your visit. Interpretive panels describing the salmon life cycle, hatchery operations, and more are available for visitors. A virtual tour of the hatchery is also available on the Department of Water Resources (DWR) YouTube channel. Guided tours of the hatchery will resume when the fall-run Chinook salmon return to the river later this year.
Over 8 million spring-run and fall-run Chinook salmon are produced by the hatchery annually, along with nearly 450,000 steelhead who are returned to the Feather River or planted in the Thermalito Afterbay for recreational users. To mitigate impacts from this third year of drought conditions, the facility will be raising an additional 1.7 million fall-run Chinook salmon to support the Feather River population. An additional 125,000 Inland Chinook will be planted in Lake Oroville this spring.
The Feather River Fish Hatchery is a California State Water Project facility owned and maintained by DWR, which funds hatchery operations. CDFW operates the hatchery, including fish spawning, rearing, and stocking activities. DWR built the fish hatchery to mitigate the impact of the Oroville Dam on Chinook salmon and steelhead populations because the dam blocks access to natural spawning grounds further upstream.

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

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

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

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

CHRISTMAS TREE FISH HABITAT
DWR, the California Conservation Corps (CCC), and the California Department of Fish and Wildlife (CDFW) completed constructing fish habitat structures at Lake Oroville and the Thermalito Afterbay using over 1,240 recycled Christmas trees. The trees were again collected by Chico Boy Scout Troop 2 and delivered free of charge to DWR by Recology, a local waste management company.
To create the habitat on Lake Oroville and the Thermalito Afterbay, members of the CCC team bundle the recycled holiday trees together and anchor them in various locations around the lakebed. At Lake Oroville near the Loafer Creek Recreation Area, 916 trees were assembled into 64 structures. At the Thermalito Afterbay, 324 trees were assembled into 32 structures. Anchoring the trees allows them to remain submerged, providing juvenile fish safe refuge, and improving fisheries and recreational fishing opportunities.
For nearly 30 years, DWR has worked with local groups to construct fish habitat structures, which is one of the longest continuously running fish habitat improvement programs in the State of California. The 2022 project is anticipated to be completed by Feb. 9.
LAKESIDE ACCESS ROAD
Construction activities associated with the Lakeside Access Road project continue to result in intermittent closures of the Oroville Dam Crest parking lot on the northwest side of the dam as well as the Spillway Boat Ramp area. These short duration closures are anticipated to continue until the end of February. The popular walking/bicycling trail across the top of the dam will remain open and parking will continue to be available at the Upper Overlook.
This project will consist of a new, permanent, paved road from the west side of Oroville Dam to the Spillway Boat Ramp parking lot on the “lakeside,” or waterside, of the Oroville Dam spillways. This new road will allow a more direct route when water levels are low in Lake Oroville. The new road will include two concrete traffic lanes, wide shoulders for walking and biking, guardrails, and safety signage.

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

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

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

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

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

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

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

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

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

Grazing Goats Reduce Fire Risk
Hillsides along the Dan Beebe and Bidwell Canyon trails near Kelly Ridge look quite different after 1,600 goats and sheep from the Hanski Family Farms visited the area.
 
The goat grazing project is part of DWR’s Fuel Load Management Plan, which helps reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville within the Federal Energy Regulatory Commission (FERC) project boundary. In partnership with Butte County Fire Safe Council, DWR utilized grazing as a sustainable method of fuel reduction on about 35 acres to help minimize the risk or lessen the spread of a wildfire.

Thermalito Afterbay Outlet Work
Divers have nearly completed work on the first stage of a 3-year project to increase the operational reliability of the Thermalito Afterbay Outlet radial gates. The gates of the Outlet have been closed this past week to allow divers to perform underwater work. The Outlet’s required flows to the Feather River were routed to the river’s Low Flow Channel that runs from the Thermalito Diversion Dam through Oroville.

As work is completed, the gates will be reopened, allowing river flows through the Low Flow Channel to gradually decrease during the week of June 21 as flows from the Thermalito Afterbay Outlet are restored. River users are always advised to be aware of currents and colder water temperatures.

Grazing Goats Reduce Fire Risk
Over 1,500 goats and sheep are busy eating their way through dried grasses and brush in the Kelly Ridge area and along the Dan Beebe and Bidwell Canyon trails. DWR staff overseeing the project report the goats are making great progress in reducing overgrown vegetation in the 34-acre target area.
 
The goats started grazing June 13 at Arroyo Drive and are moving south towards the Saddle Dam area. DWR in partnership with Butte County Fire Safe Council, contracted with Hanski Family Farms in Paradise to utilize grazing as a sustainable method of fuel reduction to help minimize the risk or lessen the spread of a wildfire. 
 
The goats and sheep will graze on dried grasses, leaves, invasive and non-invasive plants including poison oak and star thistle, and a variety of shrubs and trees. By standing on their hind legs, goats can reduce ladder fuels (overgrown vegetation that allows fire to climb from the forest floor into the taller shrubs and into the tree canopy) up to four feet high. Higher branches are being removed and placed on the ground for further grazing in order to increase fire protection.
 
The grazing area will be cordoned off with an electric fence and monitored by herdsmen 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 Plan which helps reduce wildfire risk, increase public safety, and enhance forest health in areas around Lake Oroville within the Federal Energy Regulatory Commission (FERC) project boundary. Approximately 34 acres will be grazed over the next couple weeks.

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.
 
Blue-green algae (cyanobacteria) is a natural component of ecosystems. Under certain conditions, including warmer temperatures and increased nutrient loads, algae can grow rapidly causing “blooms.” Keep animals and children away from the water when a suspected harmful algal bloom (HAB) is present and report the possible HAB immediately.
 
Water samples are taken at various locations regularly from Memorial Day through Labor Day and sent to a lab for toxin analysis. If elevated levels of cyanobacteria toxins are found while testing, DWR staff will work with California’s Regional Water Quality Control Board and recreation area managers to notify the public and post advisory signs at affected waterbodies. To learn more about HABs, or to report a HAB visit the Water Board’s website.

Current Lake Operations
The elevation of Oroville’s reservoir is about 698 feet elevation and storage is about 1.24 million acre-feet -- 35 percent full and 43 percent of historical average. Currently, in the Northern Sierra Basin, snowpack is also below average at five percent of normal. Excess heat warnings are in effect until Saturday night. Temperatures are forecast to be in the 100s over the weekend, in the 90s during the week, then increasing to be above 100 over the following next weekend.
 
Total flow to the Feather River is currently at 2,750 cfs for meeting downstream water quality and flow requirements. Due to work being performed at the Thermalito Afterbay River Outlet gates, all flow has been rerouted down the low flow channel, through the City of Oroville. Once the work is completed, flows will be rerouted at a rate of 300 cfs per day from the low flow channel to the Thermalito Afterbay Outlet until desired flows are reached. Current releases are re-assessed on a daily basis.

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”.
