What this means

At 15.95 ft, Pearl River Navigation Canal Lock and Dam No. 1 is far below normal for mid-October.

That puts it 23.42 ft below the median of 39.37 ft for mid-October, based on 20 years of readings. A year ago it stood at 16.09 ft (−0.14 ft).

The level is falling, down 23.34 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 15.95 ft and 39.37 ft.

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

What the stage means on the water

Low water means more dragging on shallow riffles and slower floats. Fish crowd into the deeper runs, and warm, low water stresses them, so play and release them quickly.
