What this means

Low water at Snake River at Nyssa: the gauge reads 5.93 ft, far below normal for mid-October.

It is still going down, by 0.10 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 5.93 ft – 6.06 ft.

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