Pennsylvania · 20 gauges · Pennsylvania river levels

The Allegheny River is tracked by 20 USGS streamgauges in Pennsylvania. This page compares each gauge’s live water level against its official National Weather Service flood stage, refreshed every 15 minutes, so you can tell whether the Allegheny River is running normal, rising toward flood stage, or already flooding. 13 of 20 gauges have both a usable water-level reading and a published minor flood stage. Gauges without a published flood stage show water level and flow only. For nearby rivers, see all Pennsylvania river levels.
