PENNSYLVANIA FLOW REPORT

Last Updated: January 1, 2026

Pennsylvania's rivers and streams are currently experiencing varied streamflow conditions across the state, with many waterways reporting below-normal flow levels. For water enthusiasts and those monitoring river health, it's important to note that significant rivers such as the Susquehanna, Delaware, Allegheny, and Lehigh are showing reduced streamflows. The Susquehanna River at Towanda, for instance, reports a flow of 16,400 cubic feet per second (cfs), which is 15.73% below normal, with a gage height of 3.89 feet. Meanwhile, the Delaware River at Port Jervis exhibits a flow of 1,690 cfs, dropping by 67.2% from what is considered normal, and the Allegheny River at Franklin holds a streamflow of 32,800 cfs, above the normal by 44.38%. These deviations indicate potential implications for ecosystems, recreation, and water supply management.

Specifically, the Lehigh River near Bethlehem is flowing at 1,140 cfs, which is a significant 71.64% below the norm, affecting popular whitewater trails in the area. Conversely, the Allegheny River at Kinzua Dam is flowing higher than usual at 11,700 cfs, which is 33.82% above normal. Cities like Pittsburgh, Harrisburg, and Scranton may also experience the effects of these trends in water levels. In particular, the Schuylkill River running through Philadelphia shows a drastically reduced flow rate at 915 cfs, 80.04% below typical levels, with a gage height of 6.02 feet. These numbers point to the possibility of flow droughts in some areas and potential flooding in others, necessitating vigilance among river communities and those who use these waterways for recreation and livelihood.
