  Lake Oroville Operations With warm temperatures here to stay in Northern California, runoff into Lake Oroville from snowmelt has significantly dwindled with outflows currently exceeding inflows. The Department of Water Resources (DWR) continues to meet water delivery and environmental requirements while optimizing water storage to allow for carryover storage into next year. Releases from Oroville Dam’s main spillway ceased in May with water being routed through the Hyatt Powerplant for power generation. When the main spillway is not in use, water may still be seen on the main spillway outlet as the seals on the eight radial gates are not designed to be watertight. The gate seals do not play a role in the structural integrity of the gates, which continue to operate as intended. Visitors to Oroville Dam may also notice minor amounts of water flowing from drains built into the emergency spillway. This is normal and expected given the emergency spillway design. The dam and emergency spillway continue to operate as intended. The information below reflects current reservoir level estimates. Forecasts can change quickly and may affect the estimates provided.
As the largest storage facility in the State Water Project, Lake Oroville helps provide water to 27 million Californians and 750,000 acres of farmland, while providing flood protection to downstream communities along with environmental and recreation benefits.

Below the Oroville Dam, the Thermalito Afterbay and the Feather River offer additional excellent fishing opportunities. Upstream migrating fish totals through the Feather River Fish Monitoring Station between January 1 and June 13 are:
Current Lake Operations Lake Oroville is at 895 feet elevation and storage is approximately 3.47 million acre-feet (MAF), which is 98 percent of its total capacity and 127 percent of the historical average. Feather River flows are at 1,200 cfs through the City of Oroville with 3,300 cfs being released from the Thermalito Afterbay River Outlet (Outlet) for a total Feather River release of 4,500 cfs downstream. DWR continues to assess Feather River releases daily. The public can track precipitation, snow, reservoir levels and more at the California Data Exchange Center.
