NOTE: Adjustments will be made to accommodate precipitation and to maintain as constant a water level as possible until "ice off" (usually around April 15). After "ice off," the gate will be closed to allow for a natural refill over the spillway level of 11.9 feet.

All footage is as measured on the gauge at the gatehouse.

*Adjustment: Emergency five-foot drawdown for cleanup of Resha Beach debris.

**Close gate, at the latest, on December 1, 2010 regardless of whether target depth has been reached and allow lake to refill naturally to three feet below spillway level.
