OLDTOWN – U.S. Army Corps of Engineers’ officials at Albeni Falls Dam announced Lake Pend Oreille elevation targets for the fall drawdown that’s underway. During drawdown, only powerhouse outflows are used, the spillway gates are not used, USACE announced in a news release.
The gradual fall drawdown began Sept. 23, with the following elevation targets, as measured at Hope, Idaho: 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.
