Current Lake Operations
The elevation of Oroville reservoir is 780 feet and storage is under 2 million acre-feet. Daily average inflows to the lake have ranged between 1,650 cfs to 2,750 cfs over the past week.
Precipitation is expected next week in the Feather River watershed. A change in the weather is in the works starting Monday night into Tuesday with the basin expecting between 0.5 and 1 inch of precipitation on Tuesday, November 26. Freezing elevations will range from 4,000 to 6,500 feet enabling snow to accumulate at higher elevations. Beyond Tuesday, an unsettled pattern sets in with possible systems dropping down from the Gulf of Alaska.
Water releases from Lake Oroville are about 2,100 cfs and will vary throughout the day and week based upon power generation schedules. Water from the reservoir continues to be used locally for rice decomposition and waterfowl habitat and released to meet environmental and flow requirements in the Feather River, as well as downstream in the Sacramento-San Joaquin Delta. The scheduled releases to the high flow channel of the Feather River, downstream of the Thermalito Afterbay River Outlet, are 2,450 cfs.
