What this means

The Rio Tanama near Utuado is running far below normal at 3.40 ft.

That puts it 0.51 ft below the median of 3.92 ft for mid-October, based on 26 years of readings. It is 7.60 ft below the flood stage of 11.00 ft. A year ago it stood at 3.55 ft (−0.15 ft).

It has dropped 0.74 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 3.07 ft and 6.89 ft.

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