The Department of Water Resource said it will release more water into the main spillway at Lake Oroville as early as Friday. The DWR said it would increase outflows through the Hyatt Powerplant , as it anticipates ongoing wet weather, rising lake levels, and increased runoff inflows into the reservoirs. The DWR said it will continue to optimize water storage in Lake Oroville to support environmental and water delivery this summer while allowing for carryover water storage into next year.
