Big Sioux River: water levels along the river

We have 17 gauges on the Big Sioux River. 2 of them read below normal for the date, and none is running high.

The gauges on this page are spread across South Dakota and Iowa. Reading the gauges in order shows how a rise or a dry spell travels downstream, usually over a day or more on a big river. Fall is often a low point for rivers after the summer, until steady rain returns.
