Whitewater safety

Check the flow before you run

Know your skill ceiling
Pick runs comfortably below your ceiling. Cold-water and big-water runs raise the consequences of any mistake.
Wear the right gear
Helmet, PFD, drysuit / wetsuit when water is below 60°F. Throw bag, knife, and whistle on your person, not in the boat.
Scout, set safety, and run with a team
Scout new rapids on foot, set safety with throw bags above the consequence pool, and run with at least one other competent paddler.
Respect the river
Strainers, undercuts, low-head dams, and wood can kill at any class rating. When in doubt, portage.
