Water Flow Information
Water conditions as of Wednesday, September 18, 2019. Please be aware that water conditions can change drastically any time depending upon weather and dam operations.
Coeur d'Alene Lake
The elevation of Coeur d'Alene Lake this morning is 2127.28. We expect the elevation of CDA Lake to decrease over the next week as Avista continues its annual drawdown. Target elevation for the end of September is one foot below full summer pool or about 2127.0.
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 2127.04. We expect the level of the water above the dam to slowly decrease due to the drawdown of CDA Lake.
Spokane River below Post Falls
The flow in the Spokane River below Post Falls this morning is about 1160 cfs, of which about 1010 cfs is flowing in the South Channel and about 150 cfs is flowing in the North Channel. The flow in the Spokane River at Spokane this morning is about 1370 cfs. Over the next week we expect flows in the river to stay about the same.
Lake Spokane at the Long Lake Dam
The elevation of Lake Spokane at the Long Lake dam is 1535.6 which is at summer elevation. We expect the elevation of Lake Spokane to stay about the same until late December. The reservoir behind Nine Mile dam will be drawn down 12 feet September 21 until mid-November. However, the Nine Mile drawdown will have no effect on the Lake Spokane reservoir behind Long Lake dam.
It is important to remember that water levels could change drastically due to a variety of factors such as weather or equipment problems at the Post Falls dam. So stay alert to signs of such changes and always exercise the highest level of personal caution when using the waterways. If you need any additional information, feel free to call (509) 495-4283.
