About

Black Canyon Water Trail runs 109 miles below Hoover Dam at flows averaging 13,546 CFS, with optimal paddling between 6,800 and 20,300 CFS according to gauge 09421500. The Bureau of Reclamation manages this designated water trail through the Colorado's controlled releases, creating predictable conditions from Eldorado Canyon down to Avi Resort. Dam-controlled flows eliminate the seasonal extremes that once defined this stretch, replacing them with steady, cold water releases that maintain year-round paddling opportunities. The trail designation provides structured access through what would otherwise be a challenging stretch to navigate independently, with coordination required through Bureau of Reclamation protocols.

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.
