Weather and Water Flow Information

Water conditions as of  8:00 am Wednesday, December 17, 2014. 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 2124.75, which is about 3 feet 3 inches below  normal maximum summer level.  Avista has begun the annual drawdown of Coeur d'Alene Lake.   Avista's goal is to have the elevation at the end of December to be at least 5 1/2 feet down from maximum summer level, or below 2122.5.

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 2123.5, which is about 4 1/2 feet below normal summer level.  We expect the water level at the bridge to slowly recede over the next month.

Spokane River below Post Falls

The flow in the Spokane River below Post Falls this morning is 4820 cfs.  The flow in the Spokane River at Spokane this morning is 4870 cfs.   We expect the flows in the river at Post Falls to stay about the same over the next week. 

Lake Spokane at the Long Lake Dam

The elevation of Lake Spokane this morning is 1535.1, which is about 10 inches below maximum.  Over the next week we expect the elevation of Lake Spokane to increase some.  NOTE:  Avista has drawn down NINE MILE Reservoir, ABOVE NINE MILE DAM, by about 6 feet to facilitate on-going construction there.   This will NOT affect the Lake Spokane (aka Long Lake) reservoir.  We expect the elevation of Nine Mile reservoir to stay at this elevation for the next few weeks.
