The flood control spillway flows remain at 0 cubic feet per second (cfs). Inflows are approximately
15,000 to 20,000 cfs which has resulted in the lake rising from 845.6 feet to 848.3 feet elevation in the
last 24 hours. Flows to meet fishery requirements are being met by releases through the Thermalito
Diversion Dam and Thermalito Afterbay River Outlet. The total flow to the Feather River remains at
2500 cfs.
Contractors continue to remove sediment and debris below the spillway. This operation will continue
24 hours per day. Approximately 168,000 cubic yards of material have been removed from the debris
pile to date.
To prepare Hyatt Powerplant for operation, reconfiguration of the powerlines connecting the plant to
the grid was completed. Work continues on the area below the emergency spillway, access roads,
and various eroded areas created by emergency spillway runoff. Rock benches and check dams are
being constructed to slow water and reduce erosion should the emergency spillway be required for
use again.

City of Oroville. California State Parks Rangers are providing roving patrols due to a large number of
contacts in the closed area.
