What this means

At 3.26 ft, Cahokia Creek at Edwardsville is below normal for mid-October.

The median for mid-October is 3.37 ft, based on 33 years of readings, so the river stage is 0.11 ft below typical. On the same day last year the reading was 4.14 ft, a difference of −0.88 ft.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 3.25 ft and 3.62 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.

What the stage means on the water

Low water means more dragging on shallow riffles and slower floats. Fish crowd into the deeper runs, and warm, low water stresses them, so play and release them quickly.
