Lake Oroville Water Operations
​The Department of Water Resources (DWR) continues to make releases from Lake Oroville using the main spillway at Oroville Dam. Ongoing releases ensure continued storage space in Lake Oroville for spring runoff from snowmelt and are closely coordinated with the U.S. Army Corps of Engineers and downstream water operators.
Total releases to the Feather River amount to 9,000 cubic feet per second (cfs) with 2,200 cfs being routed down the low-flow channel which flows through the City of Oroville. An additional 6,800 cfs is being released from the Thermalito Afterbay River Outlet, located 5 miles downstream from Oroville. DWR continues to closely monitor lake levels and will adjust releases accordingly to optimize operations for water storage and environmental protection while allowing for carryover storage into next year.  
Driftwood and other floating debris on Lake Oroville are expected due to continued water inflows from tributaries and a high lake level, in combination with past wildfires impacting the watershed. Since January, State officials and marina partners have been collecting, containing, and pulling pieces of wood out of the lake and away from boat launch ramps using boom lines. However, boaters, water skiers, and other water recreationists should take precautions when operating boats on Lake Oroville and should remain alert for floating debris.
Since Dec. 1, Lake Oroville’s storage has increased approximately 230 feet and gained over 2.44 million acre-feet of water. Lake Oroville is currently at 96 percent capacity and is expected to reach full capacity in June. The Lake Oroville reservoir is the largest storage facility in the State Water Project (SWP) and supports environmental and water delivery needs to 27 million Californians and reduces flood risks to downstream communities.

STATE WATER PROJECT ADAPTS TO CLIMATE CHANGE
​As California experiences more extreme swings between wet and dry periods, DWR continues to deploy innovative forecasting and water management strategies for the State Water Project (SWP) to adapt to California’s changing climate.
The SWP delivers an average of 2.4 million acre-feet of water to more than 27 million Californians and 750,000 acres of farmland while providing multiple benefits, such as flood control, hydropower generation, fish and wildlife protections, drinking water quality, and recreational opportunities. Releases from Lake Oroville, the largest SWP reservoir, also keep salt water from intruding into the Delta and contaminating drinking water or water used to irrigate crops.
The SWP diverts and stores surplus water during wet periods and distributes water to 29 water contractors – all public agencies that have contracts for water that is distributed to farms, homes, and industry. Annual water supply deliveries depend on rainfall runoff, snowpack, existing water in storage facilities, Delta pumping capacity, and environmental regulations.
The State Water Project is required to follow more than one regulation when releasing water from SWP reservoirs, such as Lake Oroville. Releases from Lake Oroville meet requirements set forth by the State Water Resources Control Board, U.S. Army Corps of Engineers, California Department of Fish and Wildlife (CDFW), Federal Energy Regulatory Commission, and National Marine Fisheries Service. The SWP release decisions are also coordinated with the U.S. Bureau of Reclamation which operates the Central Valley Project, since many requirements must be jointly met by the two projects.
DWR continues to explore several improvements to existing SWP infrastructure that can improve water supply reliability, water quality, water temperature control, and increased electricity integration of water supply infrastructure. Read more about DWR’s strategy for adapting to climate change.

FEATHER FALLS
​A popular excursion at Lake Oroville during high-water level periods is to take a boat trip to the upper end of the Middle Fork Arm to view Feather Falls, a Yosemite-style waterfall of exquisite beauty. Along the way, there are many smaller waterfalls to see including some that tumble directly into Lake Oroville such as Bean Creek and Frey Creek. Bring a picnic lunch, a camera, and don’t forget your fishing pole. There are unlimited bass fishing opportunities along the route and trout fishing can also be good where the cold mountain streams enter the lake.

WATER SAFETY MONTH
​The State Water Project’s (SWP) reservoirs located throughout California will welcome the upcoming summer months with high water levels. Heavy storms this past winter will also bring fast flows and cold temperatures to rivers and streams as mountain snow melts. When recreating at SWP facilities, you should always keep water safety a top priority and stay alert for cold, fast, and fluctuating water conditions.
As part of Water Safety Month, keep these water safety tips in mind to have a fun and safe summer:

• Wear a life jacket
• Swim in safe or designated areas only and near a lifeguard
• Swim with a buddy
• Be aware of drop-offs into deep water
• Watch for hidden debris and slippery rocks
• Look before you leap or dive
• Check for algal bloom updates
• Know your GPS location

Lake Oroville, the SWP’s largest reservoir, has more than 167 miles of shoreline and is a perfect location for boating, fishing, skiing, wakeboarding, swimming or paddleboarding. Those seeking to spend more than a day relaxing on the lake can rent houseboats from local marinas, stay at one of three campgrounds at the lake, or reserve floating campsites through the California Department of Parks and Recreation (State Parks).

FINAL SNOW SURVEY CONDUCTED
​DWR conducted the fifth snow survey of the season at Phillips Station this week. The manual survey recorded 59 inches of snow depth and a snow water equivalent of 30 inches, which is 241 percent of average for this location on May 1. The snow water equivalent measures the amount of water still contained in the snowpack and is a key component of DWR’s water supply run-off forecast. DWR’s electronic readings from 130 snow sensors placed throughout the state indicate the statewide snowpack’s snow water equivalent is 49.2 inches, or 254 percent of average for this date.
Snow surveys like the one at Phillips Station are critical to planning for impacts of the coming snowmelt runoff on communities. DWR uses the most updated technology to gather data from snow surveys, a network of 130 remote snow sensors, and airborne snow observatory data to gather information on current real-world conditions to create the most accurate snowmelt runoff forecasts possible. These runoff forecasts allow reservoir operators to plan for anticipated inflows and water managers downstream of reservoirs to plan and prepare for flood risks.
Read more about the latest snow survey in DWR’s press release.

BLUE GREEN ALGAE MONITORING
​DWR’s environmental scientists began monitoring for blue-green algae and their toxins last week within the Oroville-Thermalito Complex and the upper Feather River lakes. Monitoring occurs during the summer months with water samples taken at various locations regularly, which are sent to a lab for toxin analysis. There are currently no harmful algal bloom (HAB) advisories for Lake Oroville, Upper Feather River lakes, 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.” Algal blooms sometimes produce toxins that can be harmful to people and animals. Algal blooms can make the water appear green, blue, or brown in color. Seeing colors, mats, foam, scum, or paint-like streaks in the water may indicate a bloom is present. Keep animals and children away from the water when a suspected bloom is present and report blooms immediately to the California Regional Water Quality Control Board.
If elevated levels of cyanobacteria toxins are found while testing, DWR staff will work with California’s Regional Water Quality Control Board and recreation area managers to notify the public and post advisory signs at affected waterbodies. To learn more about HABs, or to report a HAB visit the Water Board’s website.

OROVILLE RECREATION ADVISORY COMMITTEE
The Oroville Recreation Advisory Committee (ORAC) will hold a public meeting on Friday, May 5 starting at 10 a.m. at the Southside Oroville Community Center located at 2959 Lower Wyandotte Road, Oroville, CA, 95966.

WATER ALLOCATIONS INCREASED
​DWR announced April 20 another increase in the forecasted State Water Project (SWP) deliveries this year. With reservoirs nearing capacity and snowmelt runoff starting to occur, DWR now expects to deliver 100 percent of requested water supplies, up from 75 percent announced in March. This water will be delivered throughout the year to the SWP’s 29 public water agencies that serve 27 million Californians and 750,000 acres of farmland. The last time the SWP allocated 100 percent was in 2006.
San Luis Reservoir in Merced County, which holds water supply for both the SWP and U.S. Bureau of Reclamation’s Central Valley Project (CVP), is now full. Additionally, Lake Oroville, the SWP’s largest reservoir, and SWP reservoirs in Southern California are expected to be full by the end of May. Statewide, reservoir storage is at 105 percent of average for this date.
“Water supply conditions and careful management of reservoir operations during this extreme winter allows DWR to maximize water deliveries while enhancing protections for the environment,” said DWR Director Karla Nemeth. “DWR is moving and storing as much water as possible to the benefit of communities, agriculture, and the environment.”
More information on SWP allocations may be found in the press release.

Lake Oroville Water Releases Continue
​The Department of Water Resources (DWR) continues to make releases from Lake Oroville using the main spillway at Oroville Dam. On Tuesday, DWR increased releases from Lake Oroville to the Feather River to assist with spring fish planting operations. Releases to the river will be further increased to 15,000 cubic feet per second (cfs) on Saturday and are expected to remain at this level through the weekend to account for higher inflow levels to the reservoir.
The increase in water flow is performed to boost survival rates of spring-run Chinook salmon as they migrate from the Feather River to the ocean. Since March 16, DWR and the California Department of Fish and Wildlife (CDFW) have been releasing juvenile spring-run and fall-run Chinook salmon into the Feather River, including 880,000 spring-run Chinook salmon smolts released this week and an additional 500,000 fall-run Chinook salmon pre-smolts.
Feather River releases are closely coordinated with the U.S. Army Corps of Engineers and downstream water operators. DWR continues to monitor lake inflow levels from spring snowmelt and will adjust releases accordingly.   
Since Dec. 1, Lake Oroville’s storage has increased more than 200 feet and gained 2 million acre-feet of water. The Lake Oroville reservoir is the largest storage facility in the State Water Project (SWP) and supports environmental and water delivery needs to 27 million Californians and reduces flood risks to downstream communities. DWR continues to monitor lake levels, weather forecasts, and mountain snow levels to optimize operations for water storage and environmental protection while allowing for carryover storage into next year.    

WATER SAFETY 
​With this season’s statewide snowpack at 237% of average as of April 3, California State Parks’ Division of Boating and Waterways (DBW), DWR and the California Department of Forestry and Fire Protection (CAL FIRE) are urging the public to take extra precautions and to be aware of cold-water dangers this spring to avoid a tragedy. The series of winter storms is causing rising river and stream flow levels not seen in years. The eventual spring warm-up will bring fast flows and cold temperatures when all that snow starts to melt. All Californians are being encouraged to wait until summer to recreate in the water, when conditions are safer.
“California has one of the largest snowpacks on record,” said DWR Director Karla Nemeth. “As this snowpack melts in the coming months, the waterways will be especially cold, fast and running higher than normal. Be aware of fluctuating water levels. We want everyone to always make safety a top priority when recreating.”
All three departments hope to educate not only regular water enthusiasts but occasional visitors to high, fast-running waterways who may venture near the edge to test the water or take selfies. Just one slip or unwatched child can become a devastating drowning statistic.
Review key safety points to know before heading outside.

DWR CONDUCTS APRIL SNOW SURVEY
​DWR conducted the fourth snow survey of the season at Phillips Station on April 3. The manual survey recorded 126.5 inches of snow depth and a snow water equivalent of 54 inches, which is 221 percent of average for this location on April 3. The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. DWR’s electronic readings from 130 snow sensors placed throughout the state indicate the statewide snowpack’s snow water equivalent is 61.1 inches, or 237 percent of average for this date.
This year’s April 1 result from the statewide snow sensor network is higher than any other reading since the snow sensor network was established in the mid-1980s. Before the network was established, the 1983 April 1 statewide summary from manual snow course measurements was 227 percent of average. The 1952 April 1 statewide summary for snow course measurements was 237 percent of average.
“This year’s result will go down as one of the largest snowpack years on record in California,” said Sean de Guzman, manager of DWR’s Snow Surveys and Water Supply Forecasting Unit. “While 1952’s snow course measurements showed a similar result, there were fewer snow courses at that time, making it difficult to compare to today’s results. Because additional snow courses were added over the years, it is difficult to compare results accurately across the decades with precision, but this year’s snowpack is definitely one of the biggest the state has seen since the 1950s.”

OROVILLE RECREATION 
DWR, State Parks, and CDFW maintain over 92 miles of trails in the Oroville area. Paved trails at the Lake Oroville Visitor Center, Spillway Day Use Area, and at the North Forebay Day Use Area offer accessible trails with only slight elevation changes. Other trails, such as the Brad Freeman Trail near Oroville Dam, offer 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. A paper trail map is available at various locations, including most entrance kiosks and the Visitor Center. The marinas at Bidwell Canyon and Lime Saddle are open daily and provide a variety of services such as a shuttle and boat rentals.

CURRENT LAKE OPERATIONS
​Lake Oroville is at 860 feet elevation and storage is approximately 2.94 million acre-feet (MAF), which is 83 percent of its total capacity and 115 percent of the historical average. Dry weather conditions will be returning to the area next week.
The Feather River releases are at 7,500 cubic feet per second (cfs). Flows through the City of Oroville are 1,000 cfs with 6,500 cfs released from the Thermalito Afterbay Outlet (Outlet) for a total of 7,500 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”.
All data as of midnight 4/6/2023.

Lake Oroville Water Releases Continue
​The Department of Water Resources (DWR) continues to make releases from Lake Oroville using the main spillway at Oroville Dam. Ongoing releases ensure continued storage space in Lake Oroville for spring runoff from rain and snowmelt and are closely coordinated with the U.S. Army Corps of Engineers and downstream water operators for flood protection.
Total releases to the Feather River amount to 12,500 cubic feet per second (cfs) with 2,200 cfs being routed down the low-flow channel which flows through the City of Oroville. An additional 10,300 cfs is being released from the Thermalito Afterbay River Outlet, located 5 miles downstream from Oroville. Releases to the Feather River will be further reduced to 10,000 cfs on Friday, March 31. DWR continues to closely monitor lake inflow levels and will adjust releases accordingly.  
Since Dec. 1, Lake Oroville’s storage has increased approximately 200 feet and gained just under 2 million acre-feet of water. The Lake Oroville reservoir is the largest storage facility in the State Water Project (SWP) and supports environmental and water delivery needs to 27 million Californians and reduces flood risks to downstream communities. DWR continues to monitor lake levels, weather forecasts, and mountain snow levels to optimize operations for flood control, water storage, and environmental protection while allowing for carryover storage into next year.    

CALIFORNIA INCREASES WATER ALLOCATIONS
​DWR announced last week a significant boost in the forecasted SWP deliveries this year due to continued winter storms in March and a massive Sierra snowpack. DWR now expects to deliver 75 percent of requested water supplies, up from 35 percent announced in February. The increase translates to an additional 1.7 million acre-feet of water for the 29 public water agencies that serve 27 million Californians.
Consistent storms in late February and March have built up the Sierra snowpack to more than double the amount that California typically sees this time of year. Rainfall has also allowed for robust flows through the system, providing adequate water supply for the environment and endangered fish species while allowing the SWP to pump the maximum amount of water allowed under state and federal permits into reservoir storage south of the Sacramento-San Joaquin Delta.
“California continues to experience weather whiplash, going from extreme drought to a series of atmospheric rivers since late December. It really demonstrates that in times of plenty, we need to move as much water into storage as is feasible,” said DWR Director Karla Nemeth. “We’ve been able to manage the system to the benefit of communities, agriculture and the environment. It’s certainly been a welcome improvement following the three driest years on record for California.”

DWR Releasing Water from Lake Oroville
The Department of Water Resources (DWR) continues to make flood control releases from Lake Oroville using the main spillway at Oroville Dam. These flood control releases are a result of high water inflows to Lake Oroville from a series of recent storms, with the purpose of protecting downstream communities.
As of today, total releases to the Feather River amount to 35,000 cubic feet per second (cfs) with 23,000 cfs being routed down the low-flow channel which flows through the City of Oroville. An additional 12,000 cfs is being released from the Thermalito Afterbay River Outlet, located 5 miles downstream from Oroville. These releases from Lake Oroville are being made in coordination with the U.S. Army Corps of Engineers and downstream water operators for flood control protection to downstream communities. DWR continues to closely monitor lake inflow levels and will adjust releases accordingly.  
Due to increased releases from Oroville Dam’s main spillway, DWR and local partners have closed Oro Dam Blvd. E. between Rusty Dusty Road and Canyon Drive in Butte County. Higher releases from the main spillway cause excessive water spray across the road and reduce driver visibility, requiring a closure for public safety. Motorists may still access Oroville Dam and the State Recreation Area via State Route 162 (Oro Quincy Highway) and Canyon Drive. This section of Oro Dam Blvd. E. will remain closed to traffic until releases from the main spillway are reduced to level that is safe for motorists.  
Since Dec. 1 Lake Oroville’s storage has increased approximately 200 feet and gained just under 2 million acre-feet of water. The Lake Oroville reservoir is the largest storage facility in the State Water Project and supports environmental and water delivery needs to 27 million Californians and reduces flood risks to downstream communities. DWR continues to monitor lake levels, weather forecasts, and mountain snow levels to optimize operations for flood control, water storage, and environmental protection while allowing for carryover storage into next year.    

Enterprise Boat Ramp Reopens
​The Enterprise boat ramp is now open for use thanks to continued rising lake levels. Open for water elevations above 842 feet, it has a two-lane paved ramp and boarding pad. Located on the south fork arm of Lake Oroville, Enterprise is also a popular place for swimming and fishing.

Update on Lake Oroville Operations
​The Department of Water Resources (DWR) is alerting Butte County and Oroville residents of the impending closure of Oro Dam Blvd. E. between Rusty Dusty Road and Canyon Drive due to increased releases from the main spillway at Oroville Dam. Beginning at 9 a.m. on Friday, March 17, Oro Dam Blvd. E. will be closed to traffic prior to increasing spillway releases in stages from 25,000 cubic feet per second (cfs) to 35,000 cfs.
When releases from the main spillway exceed 30,000 cfs, water spray can reduce driver visibility on the roadway, requiring a closure for public safety. Motorists may still access Oroville Dam and the State Recreation Area via State Route 162 (Oro Quincy Highway) and Canyon Drive. Oro Dam Blvd. E. will remain closed to traffic until releases from the main spillway are reduced.
In addition, flows through the low-flow channel within the City of Oroville will begin increasing starting at 10 a.m. Friday. Flows in the low-flow channel will increase gradually from 13,000 cfs to 23,000 cfs by 4 p.m. Releases from Lake Oroville are being made in coordination with the U.S. Army Corps of Engineers and downstream water operators for flood control protection to downstream communities. DWR continues to closely monitor lake inflow levels and will adjust releases accordingly.
