What this means

At 3.80 m, the Credit River at Boston Mills is below normal for mid-October.

The level is falling, down 0.02 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 3.77 m and 3.87 m.

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