What this means

Low water at Missouri River at Yankton: the gauge reads 10.14 ft, far below normal for mid-October.

The median for mid-October is 14.20 ft, based on 29 years of readings, so the river stage is 4.06 ft below typical. It is 9.86 ft below the flood stage of 20.00 ft. On the same day last year the reading was 10.29 ft, a difference of −0.15 ft.

It is still going down, by 0.04 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 10.02 ft – 10.47 ft.

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

How we check values

Each reading is stored as published. We hold back values that jump faster than physically plausible and show the measurement time with every value.
