Water Flow Information
Updated Monday through Friday (except holidays)
Water conditions as of Thursday, December 18, 2025. 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 2128.51, which is about 6 inches above normal maximum summer level. Lake elevation is now at its natural level as water flowing out of the lake is limited by the natural outlet restriction. Post Falls dam will pass whatever water flows out of the Coeur d'Alene Lake. We expect the elevation of Coeur d'Alene Lake to increase some over the next few days as more storms hit north Idaho and Inland Empire. We expect Coeur d'Alene to peak at about 2129.5 or 1 1/2 feet above normal summer level.
Spokane River between Coeur d'Alene Lake and the Post Falls Bridge
The following information concerns the water levels in the Spokane River above Post Falls Dam. The present water level at the Spokane Street Bridge above Post Falls Dam is 2121.78, which is about 6 feet 1 inch below normal summer level. We expect the level of the water above the dam to increase some over the next week.
Spokane River below Post Falls
All the gates at the Post Falls dam are wide open this morning. The flow in the Spokane River below Post Falls this morning is about 20000 cfs, with about 13550 cfs flowing in the North Channel and about 6450 cfs flowing in the South Channel. Flows in the river below Post Falls dam will increase over the next few days. The flow in the Spokane River at Spokane this morning is about 18500 cfs. Flows at Spokane will increase over the next few days.
Lake Spokane at the Long Lake Dam
The elevation of Lake Spokane at the Long Lake dam is 1535.0, which is a few inches below normal fall level. Lake Spokane should stay near this level or a few inches higher until mid to late January.
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 or (509) 495-4573.
