Lehigh Gorge State Park · Francis E. Walter Dam Recreation Releases

Pennsylvania's best whitewater east of the Yough — the Lehigh Gorge delivers 26 miles of Class II–IV rapids through a dramatic 1,000-foot-deep gorge in Lehigh Gorge State Park. A 26-mile rail-trail parallels the river the entire length, creating Pennsylvania's finest paddle-and-bike combination. Best on dam releases from Francis E. Walter Reservoir.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and trip sections may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level. If you spot an error, use the Improve This River button at the top of the page — your local knowledge is what makes this atlas accurate.
