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

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

Visit the California Parks Lake Oroville State Recreation Area (LOSRA) webpage for current information on facility status as well as current requirements to protect public health during the COVID-19 pandemic. Information about recreation facilities can also be found in DWR’s interactive map on the Lake Oroville Recreation webpage. For information about the Oroville Wildlife Area, including the Thermalito Afterbay, visit the California Department of Fish and Wildlife webpage.
Recreation Improvement Project Nearly Complete
Construction is nearly complete at the Bidwell Canyon Stage II Boat Ramp Project. Visitors and users can enjoy full access to the expanded, paved parking area as well as the two additional boat ramp lanes which allow launching when the lake drops as low as 705 feet elevation. Currently, boaters are using the Stage III boat ramp at Bidwell Canyon which is open 24 hours per day and provides access to elevation 665 feet.

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

Flood After Fire Preparedness
Risks for mud and debris flows to communities and homes downslope of areas burned by wildfire are increased when precipitation events occur. In normal conditions, trees, shrubs, grass, and other protective groundcover allow rainfall to infiltrate into the soil. In addition to removing vegetation, a wildfire’s extreme heat can bake the soil, further preventing water penetration. Due to these changes, even a small storm system in burn scar areas can cause flash flooding and lead to mud and debris flows.

It is important to stay alert and be prepared before flooding occurs. Being ready also means knowing when to evacuate. Get the latest information from the National Weather Service at www.weather.gov – just enter your city or zip code. More information on flood after fire can be found in this short video as well as on the DWR website.

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

These structures provide juvenile fish safe refuge, improving fisheries and recreational fishing opportunities. For over 25 years, DWR has worked with local groups to construct fish habitat structures, which is one of the longest continuously running fish habitat improvement programs in the State of California. The 2021 project is anticipated to be completed by January 29.

Snow Survey
The Department of Water Resources (DWR) conducted its first Phillips Station snow survey on Dec. 30. The manual survey recorded 30.5 inches of snow depth and a snow water equivalent of 10.5 inches, which is 93 percent of the Jan. 1 average for this location. The snow water equivalent (SWE) measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. On average, the Sierra Snowpack supplies about 30 percent of California’s water needs through spring snowmelt which feeds rivers and eventually reservoirs and aqueducts where it can be stored for use throughout the dry season. Statewide monitoring stations indicate that the state’s snowpack SWE is five inches, or 52 percent of the December 30 average.

DWR Completes Oroville Dam Safety Comprehensive Needs Assessment
The Department of Water Resources (DWR) has published a summary report of the Oroville Dam Safety Comprehensive Needs Assessment (CNA). The CNA was initiated in January 2018 to identify dam safety and operational needs following reconstruction of the spillways damaged in February 2017. A team of dam safety experts, engineers, consultants, and community representatives participated in the assessment which determined that the Oroville Dam Complex is safe to operate and no urgent repairs are needed.

The CNA identified several risk-reduction projects that DWR already is moving to implement, including installation of new water pressure measurement devices to improve seepage monitoring and completion of a state-of-the-art seismic stability analysis. DWR also is planning to implement recommendations to raise Parish Camp Saddle Dam by three feet, line Palermo Canal to reduce leakage and improve rock slope stability, and install new remote starter and power connections to the spillway radial gates to improve reliability. In addition, the CNA identified potential vulnerabilities that require further examination to better understand their actual risk. 

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

Oroville Area Algal Blooms Status
DWR environmental scientists regularly monitor Lake Oroville, the Thermalito North Forebay, and the Thermalito Afterbay for cyanobacteria (blue-green algae) and their toxins. There are currently no Harmful Algal Bloom (HAB) advisories for Lake Oroville, the Thermalito Forebay, or the Thermalito Afterbay. 

Algal blooms continue to be present in the West Branch and the North Fork of Lake Oroville. Lab analysis of water samples from these water bodies continues to find minimal or no amounts of cyanobacteria in the algae. Sampling continues weekly and if elevated levels of cyanobacteria or toxins are found, 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 the affected waterbody. Non-toxic algal blooms can be irritating or even dangerous to pets and small children. To learn more about HABs, visit the Water Board’s website and DWR’s digital article on the DWR Updates webpage. The public is encouraged to report algal blooms on the HAB reporting webpage.

CAL FIRE Forebay Control Burns Postponed
The CAL FIRE/Butte County Fire Department has postponed a scheduled a series of four control burns of about 245 acres of grassland at different locations around the North and South Forebay due to increased Northern California fire activity and the number of Butte Unit resources assisting those fires. This important vegetation management project (VMP) will take place when weather and Butte Unit staffing permits. The project is planned in cooperation with DWR and CA Parks to clear the area around the Forebays of thick grass, which reduces fire risk and benefits vernal pool habitat.
