Oroville Recreation Update
Lake Oroville and the North and South Forebay boat ramps, parking lots, and day use areas are open. Except for the Oroville Dam Spillway Boat Ramp area, which is open 5 a.m. to 11 p.m. daily, Lake Oroville State Recreation Area (LOSRA) boat ramps are open 24 hours a day, seven days a week. Trails and day use areas are open from 8 a.m. to sunset. Floating campsites and group campsites are not currently available to reduce the spread of COVID-19. For information about State Parks camping, as well as COVID-19 public health requirements while recreating, visit www.parks.ca.gov/COVID19Camping. 

The Oroville Wildlife Area (OWA), including the Thermalito Afterbay, is open 1.5 hours before sunrise to one hour after sunset and offers miles of trails and wildlife viewing. The Forebay Aquatic Center at the North Forebay Recreation Area is open Friday through Sunday 10 a.m. to 7 p.m. for boat, kayak, and other aquatic equipment rentals. Information and an interactive map of Lake Oroville and OWA recreation facilities is available on the Department of Water Resources (DWR) Lake Oroville Recreation webpage. The Lake Oroville Visitors Center remains closed due to COVID-19.

Installation of Piezometers at Oroville Dam
DWR will begin installation of four new piezometers at the headworks of Oroville Dam’s main, or flood control outlet (FCO), spillway on August 3. The piezometers will collect data from the FCO foundation. The data will be used to confirm drain performance, inform on-going structural modeling and analyses, and inform future improvements to the structure. The work is expected to be completed by August 21.

This work is part of early implementation of the Oroville Dam Safety Comprehensive Needs Assessment (CNA), which is focused on identifying priorities and appropriate solutions to bolster the integrity and resiliency of the Oroville Dam complex to ensure public safety. A number of piezometers were originally installed in the dam fifty years ago which, as anticipated, have since stopped functioning. DWR continues its work to install additional instrumentation throughout the facility including eight new piezometers installed earlier this year at the base of Oroville Dam.

Trails at Oroville Facility Offer a Variety of Scenery
The Oroville Facility Trail system features 91 miles of trails, with access to Lake Oroville, Thermalito Diversion Pool, Thermalito Afterbay, and Thermalito Forebay. Pedestrians, hikers, bikers, and equestrians can take advantage of an array of single track, fire roads, and paved trails which border beautiful natural areas, provide stunning views, and allow plentiful opportunities for wildlife viewing. Trail users can seasonally view salmon, grebes, loons, waterfowl, bald eagles, turkey vultures, snakes, frogs, and more throughout the trail network. Find area trails and their use restrictions by viewing the interactive map on the Lake Oroville Recreation 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.
