About

From Birmingham's suburban fringe through remote Bibb County bottomlands, the Cahaba River runs 194 miles to its confluence with the Alabama River. At 1,800 CFS average flow (optimal 500–3,000), this Class I–III system transitions from urban paddle trails around Trussville through the Cahaba lily shoals of Shelby County to the protected corridors of Cahaba River National Wildlife Refuge, established in 2002. The middle section through Shelby County holds the river's signature feature — rocky shoals where endangered Cahaba lilies bloom in late spring and early summer. Below that, the lower Cahaba through Bibb County offers remote paddling through floodplain forests before joining the Alabama River. Alabama designated it a state scenic river, and USGS gauge 02423500 tracks flows that can swing dramatically with seasonal rains. Cahaba Canoe Launch provides shuttle services for multi-day trips through the protected sections.

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.
