What this means

Low water at Willow Creek at Opportunity: the gauge reads 3.90 ft, far below normal for mid-October.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 3.90 ft – 3.93 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The water temperature at the gauge is 44 °F.

Compared with 5 years of daily readings for this time of year. How to read levels
