Post Falls Dam
Post Falls Dam on the Spokane River.
Post by Hugh Imhof
This has been quite a year for unusual weather. All the rain we’ve had is increasing the flow of water into Coeur d’Alene Lake. Our federal license doesn’t permit us to let the lake go above its summer level of 2,128 ft. above sea level. So to keep that from happening we’ve been letting as much water as possible spill over the dam at Post Falls. When the river runs fast, as it is now, this causes the water level to drop in the stretch of the Spokane River upstream of the dam.

Back in April we warned river users to be extra cautious because we thought there might be a lot of unusual water levels. That has happened and some boaters have been caught with their hulls on the bottom.

If the weather cooperates the river should start to rise later this week. And even though this is an unusual year for weather, it’s normal for the river to fluctuate until around the Fourth of July, when we are typically able to close the spill gates at the dam and hold the lake level steady.

We’re looking at some ways to improve communications with river users, but please remember that conditions can change very quickly and use caution on the water.

Our website gives lots of information on conditions and two phone numbers are updated daily with a river and lake report.
