The Swim You Didn't Plan For
No matter how skilled you are, time on whitewater means swimming eventually. Capsizing in serious rapids is a high-stakes situation — but it is survivable when you know what to do. Understanding how to manage your body, read moving water, and signal to rescuers can make every second count.
Immediate Actions: The First Three Seconds
When you come out of your boat, the first moments are critical. Your priorities in order:
- Get to the surface. Push off the riverbed if shallow, or let your PFD do its work in deeper water.
- Orient yourself. Identify where you are relative to the rapid and what lies downstream.
- Hold onto your paddle if possible — but never at the expense of your safety. Let it go if it's pulling you into danger.
- Decide: boat or swim? Holding your kayak provides flotation. In a calm pool, stay with the boat. In a serious rapid with no one to rescue you, sometimes getting to shore is more important.
The Defensive Swimming Position
In moving water, default to the defensive position unless you are actively trying to reach shore:
- Roll onto your back, face downstream
- Feet up and pointing downstream — this protects your legs from rock strikes
- Hips near the surface — use your arms to stay buoyant and steer
- Keep your head up to read what's coming
Never stand up in fast-moving water above knee depth — your foot can become entrapped between rocks, and the current will push you over, creating a deadly foot entrapment situation.
The Aggressive Swimming Position
When you need to reach an eddy, a rescue line, or shore, switch to the aggressive position:
- Roll onto your front
- Use a strong front crawl stroke
- Angle your body toward the target — don't fight the current directly, ferry across it at an angle
- Look up frequently to maintain awareness
The transition between defensive and aggressive positions is a practiced skill. Work on it in controlled conditions before you need it in the wild.
Reading the River While Swimming
Your ability to read water from eye level is different from reading it from a kayak. Know these features:
- Eddies: Calm water behind obstacles — your targets for self-rescue. Swim aggressively toward them.
- Hydraulics (holes): Aerated, recirculating water below drops — avoid at all costs. The foam pile traps swimmers. If caught, tuck into a ball, let the current take you to the bottom, and kick toward the downstream exit.
- Strainers: Partially submerged obstacles that let water through but not swimmers — extremely dangerous. Swim aggressively away from them. If impact is unavoidable, climb up and over aggressively.
- Pillows: Water banking up against a rock — generally push you around rather than into the rock.
Signaling to Your Group
If you are swimming and your group is nearby, use standard signals:
- Fist raised above head: "I'm okay, don't throw yet"
- Arm waving: "I need help now"
- Tapping your head: "Throw a rope"
Learn these before the trip, and ensure your entire group knows them.
Practice Makes Prepared
The best way to handle a swim in big water is to have swum in small water many times before. Practice:
- Defensive and aggressive swimming in Class II–III water
- Catching eddies while swimming
- Catching throw bags from shore
- Self-rescue techniques: re-entering a kayak, holding the boat while swimming
Swiftwater rescue courses taught by certified instructors are invaluable. Many paddling clubs offer them, and they are well worth the investment before any serious expedition.
