River safety for paddlers

The non-negotiables

• Always wear a PFD. Most paddling deaths are drownings, and most victims weren't wearing a life jacket. Wear it — don't just carry it.
• Never paddle alone if you can help it, and always tell someone your put-in, take-out, and expected return time.
• Scout what you can't see. Get out and look before committing to any rapid, bend, or horizon line.
• Dress for the water temperature, not the air. Cold water saps strength and causes gasp reflex within seconds.

The hazards that actually kill paddlers

On flat and Class I–II water, the biggest killers aren't big rapids — they're obstacles that trap you in moving water:

• Strainers — fallen trees and brush that let water through but not you. Current pins you against them. Avoid; if swept toward one, swim aggressively away.
• Low-head dams — “drowning machines.” The recirculating hydraulic below them traps swimmers and boats. Portage every dam; never run one.
• Cold water — even in summer, spring-fed and dam-release rivers can be dangerously cold.
• Foot entrapment — never stand up in moving water above knee depth; a foot caught between rocks with current pushing you over is deadly.

Learn to recognize these before you go. See the hazards guide.

When not to paddle

• When the river is high, muddy, or rising — high water is faster, colder, pushier, and full of debris. Our “high–caution” and “dangerous” verdicts exist for exactly this.
• When a storm is forecast or upstream — flash floods can raise a river feet in minutes.
• When the water is too cold and you don't have proper layers.
• When you're unsure. The river will be there next week.

Before every trip

• Check today's gauge reading and the weather — upstream too.
• Check with a local outfitter; they know the river far better than any website.
• Confirm your take-out and know the hazards in between.
• Pack: PFD, whistle, water, sun protection, a way to call for help, and dry layers.
