St. Clair River
About
Between Lake Huron and Lake Erie, 60 miles of connecting waters flow at 198,402 CFS average with optimal range from 99,200 to 297,600 CFS — massive volume that defines this as a Great Lakes shipping channel rather than a conventional paddling river. The St. Clair carries Designated Water Trail status with municipal support for recreational access. The Island Loop Route and Blueways of St. Clair provide marked paddling corridors through waters dominated by commercial shipping traffic. USGS gauge 04159130 tracks the enormous flows that connect two of the Great Lakes.
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.
