Site numbers, station names, drainage areas and record start dates come from the USGS Water Data API for each gauge; “Daily record since” is the first daily value Flowcast received from USGS, which can differ from the station's official period of record. Flow is the latest USGS reading (provisional) and the status compares it with that gauge's own history for the date. Site-number links go to the USGS page for the gauge.

Data from the U.S. Geological Survey (USGS). Readings are provisional and subject to revision. Flowcast statuses are automated comparisons with each gauge's own history, not safety ratings or fishing reports. Check local conditions, weather, regulations and closures before you go. Rivers can change quickly.
