About

Flowing 410 miles to Long Island Sound, the Connecticut River carries an average 16,000 CFS through Hartford and Middlesex counties on its final stretch to the sea. From Hartford to Middletown, tidal freshwater creates Class I conditions with reversing currents twice daily. Below Middletown to Old Saybrook, the river opens into tidelands before meeting Long Island Sound. The Connecticut River National Blueway designation recognizes the watershed's ecological significance, while the Silvio O. Conte National Fish & Wildlife Refuge protects critical habitat along the corridor. At optimal flows between 5,000-25,000 CFS (gauge 01184000), paddlers can launch through outfitters like Hurd State Park Canoe/Kayak and Connecticut River Expeditions. The lower river runs entirely Class I-II, with tidal influence extending well upstream of the mouth.

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.
