Water conditions as of 7:30 AM Thursday, October 27, 2016. Please be aware that water conditions can change drastically at any time depending upon weather and dam operations.
Coeur d'Alene Lake
The elevation of Coeur d'Alene Lake this morning is 2126.18, which is about 1 foot 10 inches below maximum summer level. We expect elevation of Coeur d'Alene Lake to stay about the same over the next couple of days. Then Avista will continue our slow Fall drawdown of the lake. By the end of November we expect the lake to be near 2124.0 or about 4 feet down from maximum summer level.
Spokane River between Coeur d'Alene Lake and the Post Falls Bridge
The following information is concerning water levels between Coeur d'Alene Lake and the Post Falls bridge. The present water level at the bridge is 2125.39. We expect the elevation of the river above the dam to continue to decrease over the next few weeks.
Spokane River below Post Falls
The flow in the Spokane River below Post Falls today is about 4330 cfs. The flow in the Spokane River at Spokane today is 4320 cfs. We expect the flow in the Spokane river below Post Falls to stay about the same over the rest of the week.
Lake Spokane at the Long Lake Dam
The elevation of Lake Spokane today is 1532.09 which is about 3 feet 11 inches below normal maximum summer level. Lake Spokane has been drawn down to provide a safety margin for workers below the spillway at Long Lake dam. The workers are modifying the spillway to prevent high levels of total dissolved gas (TDG) in the river. High levels of TDG can harm fish. The lake level will remain 1 1/2 to 6 feet down for at least several weeks. The lake may remain down through the end of the year.
