What this means

At −0.23 ft, McCormick Creek at Mouth near Key Largo is below normal for mid-October.

The median for mid-October is 0.04 ft, based on 28 years of readings, so the river stage is 0.27 ft below typical. On the same day last year the reading was 0.47 ft, a difference of −0.70 ft.

The level is falling, down 0.04 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 −0.28 ft and 0.96 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The water temperature at the gauge is 78 °F.
