Rio De Bayamon below Lago De Cidra Dam water level

What this means

The Rio De Bayamon below Lago De Cidra Dam is running far below normal at 5.59 ft.

That puts it 2.44 ft below the median of 8.03 ft for mid-October, based on 21 years of readings. It is 9.41 ft below the flood stage of 15.00 ft. A year ago it stood at 5.73 ft (−0.14 ft).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 5.53 ft and 5.73 ft.

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