Lake Oroville State Recreation Area
Lake Oroville State Recreation Area (LOSRA) boat ramps, parking lots, and day use areas are open. The Oroville Dam Spillway Boat Ramp area is open 5 a.m. to 11 p.m. with other LOSRA boat ramps open 24 hours a day, seven days a week. Trails and Day Use Areas are open from 8 a.m. to sunset. Lake Oroville recreation information is available on the Department of Water Resources (DWR) Lake Oroville Recreation webpage and the LOSRA webpage. The Thermalito Diversion Pool and the North Forebay Recreation Area are also open to the public. Additionally, the Oroville Wildlife Area, including the Thermalito Afterbay, recently changed its operating hours to 1.5 hours before sunrise to one hour after sunset.
Other local recreation facilities are also open, including both the Bidwell Canyon and Lake Oroville (Lime Saddle) Marinas and the Forebay Aquatic Center at the North Forebay Recreation Area which is open Friday through Sunday 10 a.m. to 7 p.m. for boat, kayak, and other aquatic equipment rentals.
California Department of Parks and Recreation (CA Parks) staff are working closely with Butte County health officials to develop procedures to open LOSRA campgrounds this summer. At this time, all campgrounds - including floating campsites, and the Lake Oroville Visitors Center remain closed to protect public health. CA Parks encourages visitors to maintain a physical distance of six feet or more and that gatherings, picnics, and parties are not allowed if physical distancing cannot be maintained. Local health officials also recommend face coverings, especially when you cannot maintain a safe 6-foot distance from others. Please visit the “State Parks Covid-19 Resource Center” website or the Butte County website for additional information on how to protect public health.
DWR and Partners Reduce Fire Risk
DWR has successfully completed their 2019-2020 fuels reduction season. Approximately 180 acres around the Oroville Facilities Federal Energy Regulatory Commission (FERC) Project boundary was treated through DWR’s Fuel Load Management Program (FLMP). The FLMP, administered by DWR in coordination with federal, state, and local fire and resources management agencies, aims to reduce wildfire risk, improve public safety, and enhance forest health around Lake Oroville.
Work typically starts in the fall when rainy weather arrives and continues through the winter and spring months. Treatment methods such as thinning, pile burning, grazing, lop and scatter, and prescribed burning are used to achieve fuels reduction. DWR and partners CAL FIRE, California Conservation Corps, Butte County Sheriff Office, Butte County Fire Safe Council, and private contractors are currently developing plans to start work again this fall when weather conditions allow.
Oroville Area Algal Blooms Status
DWR environmental scientists regularly monitor Lake Oroville, the Thermalito North Forebay, and the Thermalito Afterbay for 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. If elevated levels of cyanobacteria toxins are found, DWR staff 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, visit the Water Board’s website.
Online Water Education Program Goes Live on DWR YouTube Channel
Join us for Water Wednesdays at 1 p.m. on DWR’s YouTube channel. These family-friendly programs are designed for kids 10 to 14 but are appropriate for anyone who would like to learn more about California’s water resources. Recent and upcoming ‘episodes’ discuss where our water comes from: reservoirs, snowpack and groundwater. Interested participants can pre-register through Zoom; this will allow participants to pose questions to that week’s speaker.
Visit the DWR Events webpage at https://water.ca.gov/News/Events to join next Wednesday’s chat. Information will also be posted on DWR’s social media pages at @CA_DWR (Twitter) and @CADWR (Facebook). Previous episodes of Water Wednesdays are available on DWR’s YouTube channel.
