When capsized and floating on your back in swift river current?

If you find yourself capsized and floating on your back in a swift river current, it's crucial to stay calm and keep your feet up to avoid obstacles underwater. Position your body at a slight angle to the current to help guide you toward the riverbank. Use your arms to gently steer yourself if necessary, and try to look for a safe exit point. If you're unable to swim to safety, conserve energy and wait for help while keeping your head above water.
