That stands out in fall, when many rivers are usually near their lowest.

High water: what to watch for
Fast water is stronger than it looks. Even shallow water across a road can move a car, and riverbanks can be undercut and give way without warning.
Upstream gauges on the same river usually show a rise first, which is a useful early warning.
