PENNSYLVANIA FLOW REPORT

Last Updated: January 2, 2026

Pennsylvania's waterways are experiencing varied streamflow conditions, with a number of rivers and streams marking significant declines in their flow rates. Enthusiasts and communities along the Susquehanna, Delaware, and Allegheny Rivers should note that streamflow levels are generally below normal, with the Susquehanna River at Harrisburg flowing at 38,500 cfs, 17% below the norm, and the Allegheny River at Franklin registering 25,700 cfs, 44.38% above average, highlighting the most significant variance across the state. Such low streamflows across other regions, like the Lackawaxen River at Hawley showing a flow of 332 cfs, 63.85% below normal, may impact recreational activities and ecosystems. Conversely, the above-average flow in the Allegheny River could hint at potential for high-water events if trends continue or precipitation increases.

Whitewater enthusiasts, particularly, should heed the current gage height of the Youghiogheny River at Ohiopyle, a popular location for rafting, which shows a level of 1.99 feet, indicating lower than usual conditions that could affect the whitewater experience. Cities and towns near these rivers, including Harrisburg, Scranton, and Franklin, may experience varying impacts, from potential water supply stresses to effects on riverine habitats. Additionally, watershed areas for the Susquehanna, Delaware, and Allegheny rivers might face ecological shifts if these streamflow trends persist. Overall, Pennsylvania's rivers exhibit a complex and dynamic pattern of streamflow, with significant implications for recreation, water resource management, and natural habitats across the state.
