What this means

At 10.15 m, the Salmon River at Castaway is below normal for mid-October.

That puts it 0.19 m below the median of 10.34 m for mid-October, based on 16 years of readings. A year ago it stood at 10.01 m (+0.14 m).

The level is falling, down 0.01 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 10.04 m and 10.17 m.

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