What this means

At 189.89 m, the Wolf River at Highway No. 17 is below normal for mid-October.

That puts it 0.12 m below the median of 190.01 m for mid-October, based on 21 years of readings. A year ago it stood at 189.93 m (−0.04 m).

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 189.84 m and 189.93 m.

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