Key numbers

Highest on record: 92.90 ftAugust 24, 1955

Staying safe in high water

Flood stage is only the first threshold. Above it the National Weather Service sets moderate and major flood stages, and the forecast crest tells you which of those the river is expected to reach.

Upstream gauges on the same river usually show a rise first, which is a useful early warning.
