Each year the United States Army Corps of Engineers releases a schedule for the draw down of Lake Tulloch to winter levels. The fall drawdown schedule for Tulloch Reservoir is provided below. The reservoir will generally be managed to the target elevation range, however some variation may occur due to large local inflow during rain events or facility and operational constraints. Beginning in spring the lake level will be increased.
The Copper Cove Association continues to work with our United States Congressman and Calaveras and Tuolumne County Supervisors to insure our lake level continues to be stable and not impacted by some of the schemes of the California State Water Board.
