Snowpack Survey

The Department of Water Resources (DWR) conducted the third snow survey of the season Tuesday at Phillips Station near Echo Summit. Following a January and February that will enter records as the driest documented in state history, the manual survey recorded 35 inches of snow depth and a snow water equivalent of 16 inches, which is 68 percent of average for this location for March.

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 is 63 percent of average for this date. “With only one month left in California’s wet season and no major storms in the forecast, Californians should plan for a third year of drought conditions,” said DWR Director Karla Nemeth. 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.

Feather River Hatchery Steelhead Planting

The Feather River Fish Hatchery 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 in December 2021 and February 2022. This is a significant increase from normal planting years and will contribute to a more productive recreational fishery. 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.

Oroville Recreation

The Loafer Point, Bidwell Canyon, and Lime Saddle boat ramps are open. The Oroville Dam Spillway boat ramp remains closed for repairs. The Foreman Creek and Stringtown cartop boat ramps are also open.

Intermittent, short duration closures of the Oroville Dam Crest parking lot may occur to accommodate Lakeside Access Road construction activities. 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.

Information on current boat ramp status can be found on the California State Parks’ Lake Oroville State Recreation Area webpage. Scroll down to the link for “Current Launch Ramp Status”.

The Lake Oroville Visitor Center is open to the public on Tuesdays, Wednesdays, and Thursdays from 9 a.m. to 5 p.m. Pick up the Lake Oroville Trails Map, which shows more than 97 miles of trails available to equestrians, bicyclists, and hikers, at Lake Oroville State Recreation Area (LOSRA) kiosks, the Oroville Area Chamber of Commerce, and Feather River Recreation and Parks District. The Loafer Creek Recreation Area continues to be closed due to waterline repair (boat ramp and trail access allowed).
