Listed by state and station name, not upstream-to-downstream order. County, coordinates and measurement types come from our USGS station catalog; availability can change.

PUT THE READINGS IN CONTEXT

Use the right station, not just the river name.

Gauge height uses a station-specific reference and is not the river’s depth everywhere. Local rainfall, tributaries, tides and dam operations can affect readings differently. Open the individual gauge for its charts and available historical context.

These observations are not a flood warning or a recreation safety rating. Check official warnings, closures and local guidance before acting.
