River levels by state

riverlvl — live river flows, gage heights and flood stage for 250 USGS gauges.

Streamflow and gage height from the U.S. Geological Survey. Flood categories, impact statements and forecasts from the NOAA / National Weather Service National Water Prediction Service. Both are public-domain sources. Readings are provisional and subject to revision.

riverlvl is not an official source and does not issue warnings. Plain-English summaries on this site are derived from the published data by rule, not written by a forecaster. For official flood warnings see weather.gov.
