  October 23, 2020 Fire Impacts to Lake Oroville The Department of Water Resources (DWR) is a member of the “Watershed Working Group” led by the California Office of Emergency Services (Cal-OES). The working group is a multi-agency team evaluating and identifying areas of concern in the Feather River watershed affected by recent wildfires. Field teams are taking action to address erosion, debris runoff, and water quality impacts. DWR’s Division of Flood Management is currently assisting California Conservation Corps members to install erosion control measures in areas of concern. DWR water quality experts have expanded water sampling activities at Lake Oroville and continue to monitor for algal blooms and other environmental concerns. After the 2018 Camp Fire, data collected by DWR environmental scientists showed no long-term impacts to water quality in Lake Oroville. The clearing of debris entering Lake Oroville is part of ongoing DWR maintenance of Lake Oroville. Additional work is planned to protect boaters and ensure safe operation of dam facilities. Several ancillary DWR facilities around Lake Oroville experienced fire damage. DWR staff are making repairs to the impacted facilities. Oroville Recreation The Lime Saddle and Oroville Dam Spillway boat ramps are open. The Bidwell Canyon boat launch is only open weekends, 5 a.m. Saturday to midnight Sunday, while weekday construction continues to build boat ramp lanes to 700 feet, which will provide additional boat access when lake levels are low. The project is expected to be completed mid-November. Bidwell Canyon and Lake Oroville (Lime Saddle) marinas are open for normal operation under regular winter schedules. 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. The Potter’s Ravine and North Fork trails near the Spillway boat launch area and trails in the Loafer Creek recreation area are closed to repair fire damage. Enterprise, Stringtown, and Foreman Creek boat ramp areas, the Loafer Creek Recreation Area, and Lake Oroville Visitor Center also remain closed. Current recreation facility information can also be found on DWR’s Lake Oroville Recreation webpage. Information for the Oroville Wildlife Area, including the Thermalito Afterbay, is available on the CA Department of Fish and Wildlife webpage.

Campgrounds at these areas, except Lake Davis, which is open until Oct. 31, have closed but trails, boating, and other recreation is allowed. Visitors are advised to be alert for firefighting equipment and personnel. Visit the Plumas National Forest webpage for fire restrictions, alerts, notices, and maps.  Chinook Salmon Return to the Feather River
The fall-run of Chinook salmon is peaking later than usual this fall, delighting fishing enthusiasts, area residents, and visitors. As the salmon return home to the Feather River to lay eggs for the next generation of salmon, the Feather River Fish Hatchery is also continuing their spawning operations which enable millions of Chinook salmon to be released to the river every spring. While the hatchery is not open for tours this year due to the COVID-19 pandemic, the Viewing Area near the Feather River’s Fish Diversion Dam north of the Hatchery remains open to visitors. The public is urged to maintain physical distancing and abide by requirements for mask-wearing to protect personal health and the health of others.

October 16, 2020 Fire Impacts to Lake Oroville The Department of Water Resources (DWR) is a member of the post-fire task force led by the California Office of Emergency Services (Cal-OES). The task force is a multi-agency team that will evaluate and identify areas of concern in the watershed. They will coordinate and prioritize actions to address erosion, debris runoff, and water quality impacts to the watersheds impacted by wildfire. DWR environmental scientists actively monitor Lake Oroville for water quality, algal blooms, and other environmental concerns, including wildfire impacts. After the 2018 Camp Fire, DWR installed additional monitoring stations. The data collected by DWR environmental scientists did not show long-term impacts to water quality in Lake Oroville. As part of routine maintenance year-round, DWR takes steps to reduce erosion on the lake’s shoreline. The clearing of debris entering Lake Oroville is part of ongoing DWR maintenance of Lake Oroville to protect boaters and ensure safe operation of the dam facilities. Oroville Recreation The Lime Saddle and Oroville Dam Spillway boat ramps are open and the Bidwell Canyon boat launch is open on weekends while construction, expected to be completed in November, is underway.

The work to remove conductors from transmission lines extending over the West Branch waterway near where it joins the Feather River’s North Fork of Lake Oroville is anticipated to be rescheduled later in August.  Grebes Nest Receive Help from DWR Western and Clark’s grebes, with their distinctive red eyes, graceful necks and long yellow bills, have returned to the Thermalito Afterbay for their nesting season. The shallow nature of the Afterbay is perfect for these two species of grebes who, along with only a few other aquatic bird species, nest on the water. DWR voluntarily restricts the elevation of the Thermalito Afterbay because significant decreases in reservoir elevation could strand the nests out of the water or submerge them if elevations increase. Find more information about the grebes at the DWR Updates webpage. Photos can be found on DWR’s Pixel webpage – enter Grebes in the search bar after creating a user name and password to log in.  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 many locations around 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.
