What this means

At 2.47 ft, the Tongue R below Brandenberg bridge near Ashland MT is far below normal for late October.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 2.42 ft and 2.53 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 56 °F.
