What this means

Low water at Rio Gurabo at Gurabo: the gauge reads 4.12 ft, far below normal for mid-October.

The median for mid-October is 5.15 ft, based on 37 years of readings, so the river stage is 1.03 ft below typical. It is 15.88 ft below the flood stage of 20.00 ft. On the same day last year the reading was 4.20 ft, a difference of −0.08 ft.

It is still going down, by 0.06 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 4.06 ft – 6.23 ft.

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