If you end up being swept down a river you need to Survival Swim using the Whitewater Position.
To Survival Swim using the Whitewater Position:
• Float on your back
• Face downstream with your feet and toes just at the surface
• Have your arms by your side free to scull if required
• Keep your head up
• Turn your hips slightly to one side so that if you bump over rocks your butt cheeks hit the rocks, not your tailbone.
When you see a place to get out of the river plan early to:
• Propel yourself toward the exit point with your arms
• Change to swimming or side swimming strongly to get over the eddy line and reach the river bank.
