OROVILLE – The California Department of Water Resources (DWR) today determined use of Lake Oroville’s flood control outlet spillway (also known as the main spillway) is now unlikely this week. The weather system experienced in the Feather River basin over the weekend, while delivering an unusually high amount of precipitation for this time of year, did not meet anticipated forecasts that would have required use of the main spillway.
Inflows into the reservoir peaked on Saturday at just over 54,000 cubic feet per second (cfs). A steady outflow of 13,000 cfs from Hyatt Powerplant kept the elevation of the reservoir below 800 feet. With inflows continuing but tapering off, releases out of Hyatt Powerplant began decreasing to 10,000 cfs beginning at noon today.
The following provides the most current approximate information:
- Lake Oroville Elevation: 799.70 feet
- Inflow: 23,000 cfs
- Spillway Outflows: 0
- Hyatt Powerplant Outflow: 11,250 cfs
- Feather River Flows: 11,500 cfs
