USGS provisional observation · station 01576000
Stage is the water height relative to this station’s local gauge datum. It is not the elevation above sea level and not a river-wide depth.
USGS publishes a current stage at this station, but the daily mean series needed for this chart was not returned. Follow the source link for its available graphs.
Daily mean values, when USGS supplies them, are separate from the latest instantaneous reading above.
USGS continuous readings can be revised. This page provides a dated snapshot of parameter 00065 (gage height). It does not apply a flood-stage label, predict future levels, or determine whether a route or property is safe.
