About

From Sunbury through Harrisburg, the Susquehanna carries an average 24,800 CFS through 60 miles of island-studded Class I water across Northumberland and Dauphin counties. The river runs wide and forgiving at optimal flows between 5,000 and 30,000 CFS, though paddlers should check gauge 01570500 before launching — this much water moves fast when it wants to. City Island in Harrisburg creates ledges that bump the rating to Class I–II through the urban corridor, then the river begins its tidal transition toward the Chesapeake. Between the 1830s and 1900, lumber rafts ran the Great Drives down the Susquehanna, moving Pennsylvania timber to market. The river holds designation under the Pennsylvania Scenic Rivers Program and serves as part of the Captain John Smith Chesapeake National Historic Trail. The Susquehanna River Trail Association coordinates access and information for the 444-mile system.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
