What this means

Low water at Redwater Creek at Wy-Sd State Line: the gauge reads 2.97 ft, far below normal for mid-October.

The median for mid-October is 3.26 ft, based on 9 years of readings, so the river stage is 0.29 ft below typical. It is 9.03 ft below the flood stage of 12.00 ft. On the same day last year the reading was 3.24 ft, a difference of −0.27 ft.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 2.87 ft – 3.00 ft.

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