SEATTLE -- U.S. Army Corps of Engineers officials at Albeni Falls Dam announce Lake Pend Oreille elevation targets for the upcoming 2025 fall drawdown.
A gradual fall drawdown is scheduled to begin Sept. 22, with the following elevation targets (as measured at Hope, Idaho):
- Hold summer pool elevation, 2,062-2,062.5 feet, through Sept. 21.
- Target 2,060-2,061 feet by Sept. 30.
- Target 2,051-2,051.5 feet no later than Nov. 15.
- Hold 2,051-2,051.5 feet elevation band until Kokanee spawning is complete, generally late December.
Fall drawdown serves multiple purposes by accommodating fall/winter Kokanee spawning and creating space for flexible winter power operations. Only powerhouse outflows are used during drawdown.
USACE and Bonneville Power Administration representatives will host an Open House Oct. 7, 5:00 p.m. – 8:00 p.m. at the Sandpoint Community Hall, Sandpoint, Idaho. The public is invited to visit with staff at their convenience to learn more about ongoing projects at the dam. Topics will include Water Management, Spillway Gate Replacement Project, Invasive Species Management and Springy Point Recreation Area.
The Army Corps operates Albeni Falls Dam as a multiple-purpose project, providing flood risk management, recreation, power generation, fish and wildlife conservation and navigation.
