About
Clarion River — Pennsylvania's Wild and Scenic Forest Stream. Through 120 miles of Pennsylvania's Allegheny National Forest, the Clarion River transitions from Class I-II meandering in open valley to the demanding Class II-III drops of Cooksburg Gorge before widening toward its confluence with the Allegheny. The middle section's 15-mile gorge represents the river's technical heart, where paddlers find the steepest gradient and most continuous whitewater. At 1200 CFS average with an optimal range of 400-2000, the Clarion runs through Clarion and Forest counties on flows substantial enough to push loaded canoes through extended wilderness stretches. Wild & Scenic designation came in 1996, protecting corridors that hosted Pennsylvania's last great log drives from the 1820s through 1900. The upper Clarion from Ridgway to Clarion town offers classic Class I-II touring water, while the lower river spreads wider and gentler as it approaches the Allegheny confluence. Cook Forest State Park anchors access and services, with Clarion River Kayak and Canoe providing outfitting.
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.
