Resource managers will begin the fall drawdown of Lake Pend Oreille on Tuesday, Sept. 19, in keeping with the typical schedule of holding the lake at its normal pool of 2,062.5 feet until the third Sunday in September or Sept. 18 — whichever is later.
According to the Lakes Commission, “Reasonable efforts will be made to be above 2,061 feet through the fourth Sunday or Sept. 25. At that point, there will then be a gradual draft until Nov. 15, when the lake needs to be at winter pool for kokanee. Please keep in mind that during drawdown, elevations on the Pend Oreille River, especially as you get closer to the dam, can be feet lower than the lake elevation measured in Hope.”
Reaching the winter pool elevation by Nov. 15 is necessary so shoreline kokanee have the necessary depth to spawn. Though not required, winter pool of 2,051 feet has been the norm for many years. That equates to the full 11.5 feet of stored water and is lowered to this maximum level for flexible winter pool operations by the Bonneville Power Administration, which generates power in the winter by raising the lake and then releasing that water again.

Elsewhere in the panhandle, the Idaho Department of Water Resources plans to begin the fall drawdown of Priest Lake on Sunday, Oct. 1, which is about a week early, in order to accommodate planned construction on the dam scheduled to resume on Nov. 1.
The Lakes Commission advises those who need to winterize waterfront infrastructure to be aware of the early drawdown and plan accordingly.
Drawdown info, including daily release rates, should be announced on the IDWR website in the coming week: idwr.idaho.gov/streams-dams-floods/lake-management.

Meanwhile, the Lakes Commission will be meeting on Thursday, Sept. 21 from 1-4 p.m. at the West Bonner Library in Priest River (118 Main St., Priest River), where attendees will hear from U.S. Sen. Jim Risch’s office on the Columbia River Treaty, get an overview of Albeni Falls Dam operations, an update on the Priest River fishery, rural wastewater info from the Panhandle Health District, a presentation by the Idaho Department of Fish and Game on current Pack River Delta restoration work and more.
Lakes Commission meetings are open to the public. For those who wish to participate via Zoom, register at bit.ly/3sQjYV6.
