DWR today announced that use of the Lake Oroville main spillway is unlikely this week. 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.
As of noon on April 7, 2018 -- Lake Oroville elevation is 796 feet, inflow is 50,000 cfs, spillway outflow is 0, Hyatt Powerplant outflow is 13,000 cfs, and Feather River flows are approximately 13,750 cfs.
As of noon on April 6, 2018 -- Lake Oroville elevation is 792.55 feet, inflow is 12,700 cfs, spillway outflow is 0, Hyatt Powerplant outflow is 13,000 cfs, and Feather River flows are approximately 13,750 cfs.
As of noon on April 5, 2018 -- Lake Oroville elevation is 793.20 feet, inflow is 8,000 cfs, spillway outflow is 0, Hyatt Powerplant outflow is 13,000 cfs, and Feather River flows are approximately 13,750 cfs.
Hyatt Powerplant outflows are increasing to 13,000 cfs at 1pm. As of noon on April 4, 2018 -- Lake Oroville elevation is 794.04 feet, inflow is 9,000 cfs, spillway outflow is 0, Hyatt Powerplant outflow is 9,500 cfs, and Feather River flows are 10,000 cfs.
DWR today announced awarding $85.8 million in grants for groundwater sustainability projects that directly benefit severely disadvantaged communities.
Forecasted storms expected in the Feather River basin this weekend may require using Lake Oroville’s flood control outlet spillway (also known as the main spillway) this week or next.
Today’s snow survey by the California Cooperative Snow Surveys Program indicates that water content in the statewide mountain snowpack increased from 23 percent of the March 1 average to 52 percent of today’s historical average. The early-April snow survey is the most important for water supply forecasting because the snowpack is normally at its pe ...
The underground secant pile cutoff wall was completed on March 7, 2018 and crews are placing roller-compacted concrete for the emergency spillway splashpad.
As part of ongoing work to improve California’s preparedness for dry conditions and better adapt to climate change, DWR has released results of a study examining Southern California tree-ring data, and the centuries-long story the tree-rings reveal.
