With plenty of melting snowpack, remember that mountain rivers and streams are cold and can be very swift! People in or near area lakes, rivers, and streams should remain cautious to the dangers of cold springtime waters. If exposed to cold waters, even experienced swimmers can lose muscle control very quickly, and any fast flowing water will make rescue difficult. Practice cold water safety techniques or avoid going into the water. Recognize the signs of hypothermia; such as shivering, cold hands and feet, poor coordination or loss of dexterity, and mental sluggishness. Alcoholic beverages can speed the onset and progression of hypothermia. Always keep a close eye on children around the water.
