What this means

Low water at Sf Stillaguamish River near Granite Falls: the gauge reads 3.55 ft, below normal for mid-October.

The median for mid-October is 4.97 ft, based on 11 years of readings, so the river stage is 1.42 ft below typical. On the same day last year the reading was 6.03 ft, a difference of −2.48 ft.

It is still going down, by 0.14 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 3.26 ft – 5.06 ft.

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