Pennsylvania River Flow Rates & Stream Gauge Data

Live USGS stream gauge data for Pennsylvania — current CFS flow rates, gauge heights, water temperatures, and wading conditions for Pennsylvania rivers and streams. Updated every 15 minutes. Know before you go.

Planning with Pennsylvania river conditions

Browse USGS monitoring stations across Pennsylvania rivers and streams. Each gauge page shows current readings plus 7, 14, and 30-day flow-rate charts with condition indicators. Compare the station name and location with your intended reach, then use the recent trend alongside the current reading. Rain, snowmelt, dams, tributaries, and the distance between stations can produce different conditions on the same river.

Pennsylvania river guides

• Allegheny River — The Allegheny is a large Pennsylvania river with extensive mapped trout and fishing-water coverage. Its size makes gauge location, access, and flow trend essential parts of trip planning.
• Penns Creek — Penns Creek is a limestone-influenced Pennsylvania trout stream with a strong hatch-fishing identity and enough flow variation that a current gauge check is worthwhile.
