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.

 
 

Heat-Related Illnesses

Visitors should also be cautious of heat exhaustion and heat stroke. These conditions are caused by exposure to high temperatures and humidity, especially when combined with strenuous physical activity. Always stay hydrated, avoid extended exposure to the sun, and stay cool in hot conditions.

Heat exhaustion can be treated by moving to a cooler place, drinking water, and loosening clothes. However, severe heat exhaustion can lead to a heat stroke. Call 911 immediately if you suspect you or someone else may have heat stroke and move the person to a cooler place while you wait for help to arrive.
