Hypothermia

Hypothermia is possible, especially on the river, even during the summer. Even if it is hot out, the river water can be very cold. Wear appropriate clothing, stay dry, and keep active to stay warm in cold weather. If you suspect you or someone else may have hypothermia, move to a warm, dry place to rest and replace any wet clothing with dry clothing.
