What this means

Low water at Don River at Todmorden: the gauge reads 12.12 m, below normal for mid-October.

The median for mid-October is 12.15 m, based on 19 years of readings, so the water level is 0.02 m below typical.

It is still going down, by 0.05 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 12.10 m – 12.94 m.

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