What this means

At 6.55 ft, the Lake Moultrie Tailrace Canal at Moncks Corner is below normal for mid-October.

That puts it 0.36 ft below the median of 6.91 ft for mid-October, based on 25 years of readings. A year ago it stood at 7.25 ft (−0.70 ft).

The level is falling, down 0.83 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 4.49 ft and 9.03 ft.

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 70 °F.
