Whitewater safety
- Check the flow before you run
- Use the linked-gauge card and Regional Flow panel above. Class ratings change with flow -- a Class III at low water can become Class IV+ at high water.
- 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.
