Water Flow Information
Updated Monday through Friday (except holidays)
Water conditions as of Friday, January 30, 2026. 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 2123.30, which is about 4 feet 8 inches below normal maximum summer level. Coeur d'Alene 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 a small amount over the weekend because of warm temperatures and melting snow.
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 2120.5, which is about 7 feet 4 inches below normal summer level. We expect the level of the water above the dam to stay about the same 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 5000 cfs, with about 100 cfs flowing in the North Channel and about 4900 cfs flowing in the South Channel. Flows in the river below Post Falls dam will increase a small amount over the weekend into next week. The flow in the Spokane River at Spokane this morning is about 6000 cfs. Flows at Spokane will increase over the weekend into next week.
Lake Spokane at the Long Lake Dam
The elevation of Lake Spokane at the Long Lake dam is 1535.7, which is at normal fall level. Lake Spokane should stay near this level until mid-February. If a drawdown of Lake Spokane is to occur this year, it won't happen until mid to late February.
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.
