If you are caught in surging water
Any moving water can be dangerous. If you are caught in the water and swept off your feet, remember the following:
Drop any items that can weigh you down.
Stay calm, lie on your back, and keep your feet up and pointed downstream to avoid rocks and foot entrapment.
Swim on your back with the current and then diagonally across the stream until you reach the shore.
Do not attempt to stand up until you are in shallow, slow-moving water.
If you get trapped on an island, stay there and signal for help.
