About

From Pittsburg through New Hampshire's remote upper valley to the Vermont border, the Connecticut River flows 270 miles through Grafton and Coos counties at an average 6,200 CFS. The upper section from Pittsburg to Lancaster cuts through moose country — true backcountry paddling with minimal development. Below Lancaster, the river enters pastoral farmland around Dartmouth College territory near Hanover, then continues south through Class I-II water past covered bridges to Charlestown. Optimal flows run 2,000 to 10,000 CFS on gauge 01138500, giving paddlers a wide window for planning trips. The Connecticut River National Blueway designation protects the corridor, while the Silvio O. Conte National Fish and Wildlife Refuge manages critical habitat along the watershed. North Star Canoe Rentals operates on this section for paddlers without their own boats.

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.
