  • 22-058 Seasonal drawdown for Lucky Peak to begin Aug. 14

    BOISE, Idaho – The U.S. Army Corps of Engineers and the Bureau of Reclamation will begin gradually lowering the pool elevation of Lucky Peak Reservoir over the next two weeks to an elevation of 3,052 ft (3ft from full pool). Starting Aug. 14, the seasonal drawdown to the winter pool will begin. The lake will drop 1-3 feet a day until the winter pool elevation of approximately 2,945 feet is achieved by late September or early October, depending on future irrigation demand. As water levels decrease, recreators should be aware of boat ramp elevations as the drawdown will ultimately impact recreation.
