August 27, 2021 Oroville Dam Citizens Advisory Commission Public Meeting The California Natural Resources Agency held its eighth Oroville Dam Citizens Advisory Commission meeting on August 27, 2021. The online public meeting included an overview of major projects and maintenance plans at the Oroville Dam facilities and a presentation by a State Water Contractor. Members of the public also offered comments and asked questions. The Citizens Advisory Commission is a forum to provide public feedback from the communities surrounding Oroville Dam. The meeting transcript and presentations will be available on the Commission’s website in the coming weeks, visit https://bit.ly/OrovilleCAC. 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.

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 and open to pedestrians and bicyclists 24-hours a day. The Lake Oroville Visitor Center anticipates re-opening later this summer. Visit the California Parks LOSRA webpage for current information on facility status and campground reservations. An interactive map of recreation facilities in DWR’s Oroville-Thermalito Complex is available on DWR’s Lake Oroville Recreation webpage. Information about the 11,000-acre Oroville Wildlife Area is available on the California Department of Fish and Wildlife webpage. And don’t forget to pick up the new Lake Oroville Trails map now available at many Oroville locations including LOSRA kiosks, Oroville Wildlife Area office on Oro Dam Boulevard West, the Oroville Area Chamber of Commerce, and Feather River Recreation and Parks District. Over 97 miles of trails maintained by State Parks and DWR are included.

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. DWR is encouraging water conservation efforts by all Californians. Find out ways you can help by visiting the “Save Our Water” website. Current Lake Operations The elevation of Oroville’s reservoir is about 631 feet elevation and storage is just below 803-thousand acre-feet which is 23 percent of its total capacity and 34 percent of historical average. Temperatures in the upper 90s are expected this weekend and cooling down to the high 80s and low 90s next week. Total flows to the Feather River are 1,250 cfs 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”.
