What this means

Low water at Missouri River below Greenwood: the gauge reads 23.29 ft, below normal for mid-October.

The median for mid-October is 26.36 ft, based on 29 years of readings, so the river stage is 3.07 ft below typical. It is 6.71 ft below the flood stage of 30.00 ft. On the same day last year the reading was 25.14 ft, a difference of −1.85 ft.

It is still going down, by 0.58 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 22.38 ft – 26.22 ft.

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