The Hazard of Cold Water Boating

 

The National Weather Service in Caribou, Maine urges extreme caution when boating, canoeing, or kayaking during the spring, when water temperatures typically remain dangerously cold in the event of a capsize.

After a long Maine winter, thoughts naturally turn toward warm weather recreational activities. The first warm days of spring often attract boaters and other recreational enthusiasts to the many beautiful lakes, rivers, and streams across the state.

Those venturing out area lakes and rivers need to be aware of the dangers posed by cold water temperatures. On pleasantly warm and dry days in May, it is easy to overlook the fact that the temperature of the water much more slowly than air temperature. Rivers are often still affected by runoff from melting snow. Lakes continue to up-well cold water from below until a temperature of 39°F has been reached. Then they increase in temperature slowly based on the amount of days and sunshine, near surface air temperature, and the size of the body of water.  Water temperatures can still be in the 30s and 40s well into the month of May.

Immersion in cold water can become life threatening very quickly. Should your craft capsize, hypothermia in waters with temperatures in the upper 30s and 40s can occur in just a matter of minutes. Since water conducts body heat away up to 26 times faster than air of the same temperature, the cold water rapidly causes extremities to become numb, weakening the ability of muscles to work effectively. Tragically, two young men lost their lives in Aroostook County last year, drowning in the very cold water temperatures in May.  

Consider postponing water recreation activities until later in the spring when water temperatures have had time to warm. However, if you are determined to go out on the water, proper preparation is essential. Follow these tips:

  1. Make sure your boat is in good condition.
  2. Check the weather forecast before you leave.
  3. Always tell someone where you are going and when you expect to return.
  4. Dress in several layers of clothing. A diver’s wet suit offers the best protection against cold. If you do not have a wet suit, wool clothing is the next best option.
  5. Always wear a life jacket!

Safe boating is no accident! Please take the time to think safety first and plan appropriately for weather and water conditions before heading out on lakes, rivers, and streams. Visit these links for more information.
