What this means

At 0.71 m, the Expanse Coulee near the Mouth is below normal for mid-October.

That puts it 0.03 m below the median of 0.73 m for mid-October, based on 14 years of readings. A year ago it stood at 0.70 m as well.

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 0.69 m and 0.82 m.

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