U.S. Army Corps of Engineers’ officials at Albeni Falls Dam announce Lake Pend Oreille elevation targets for the upcoming fall drawdown. During drawdown, only powerhouse outflows are used, the spillway gates are not used.
A gradual fall drawdown is scheduled to begin Sept. 23, with the following elevation targets (as measured at Hope, Idaho):
- Hold summer pool elevation, 2,061.75-2,062.25 feet, through Sept. 22.
- Target 2,060-2,061 feet by Sept. 30.
- Target 2,051-2,051.5 feet no later than Nov. 15, 2024.
- 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.
USACE representatives will host a public meeting Oct. 7, 2024, 6:00 p.m. - 8:00 p.m. at Ponderay Event Center, Ponderay, Idaho. Topics to discuss include dam operations and the latest status of the Albeni Falls Dam Spillway Gate repair and replacement project.
