What this means

Low water at San Antonio River at Goliad: the gauge reads 3.54 ft, below normal for mid-October.

That puts it 0.71 ft below the median of 4.25 ft for mid-October, based on 33 years of readings. It is 21.46 ft below the flood stage of 25.00 ft. A year ago it stood at 3.00 ft (+0.54 ft).

It is still going down, by 0.33 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The sensor also reports a water temperature of 69 °F.
