Cold Water Safety At Devil’s Lake

Cold Water Safety At Devil’s Lake

Well, the ice is off the lake here at Devil’s Lake State Park and that means people will be in a rush to get out on the water. Well, hold up there cowboy, the water is cold! Waay Cold!! So cold that if you fall out of your boat, canoe or kayak without the proper gear you could die within minutes. No, seriously!

When it comes to cold water, “risk” comes in stages. The first risk you take when hitting the water this time of year is called “Cold Shock”. Cold shock happens when your body is suddenly immersed in cold water and can kill you within 3-5 minutes.  Cold shock has been seen even in water temperatures as high as 77°F! (The water at Devil’s Lake in March & early April is between 40f & 50F) Sudden immersion in cold water can cause a gasp reflex and drowned you almost instantly. If you survive the initial hit, your body can spasm and breathing rates will increase rapidly. You may experience extreme muscular pain. You will be gasping for air. The combination of muscle spasms and rapid breathing will make swimming nearly impossible at first. During the first few moments after you find yourself in the water, you will likely put your face into or below the surface of the water whether you want to or not. It only takes an inhalation of about five ounces of water to cause drowning.  You don’t want to be in this situation.

If you manage to survive the first few seconds of cold water immersion, the clock is running. Now the risk you are facing is called “Swimming Failure”. You can expect to have anywhere from 5-30 minutes to get to safety before you simply won’t be able to swim.  There are many variables here, water temps, how you’re dressed, you’re general health, etc. Thing is, most people will go out in a boat figuring that if they do fall in, they have time to swim to shore even if it’s cold. A big mistake. You see, you ability to swim quickly deteriorates with each minute of cold water immersion. Your muscle control is slipping away and even your ability to think will wear away. Boaters who have fallen in often learn that getting back in their boats just isn’t as easy as they assumed. Often they simply decide to swim for shore. As they fight seizing muscles to swim in the cold water, they will continuously struggle for air. Their muscles will quickly weaken and feel numb.  Sometimes swimmers just never make it to shore.

All during this “Swimming Failure” stage you are slipping into hypothermia. Even if you make it to shore, you’ll still be facing hypothermia and will need to warm up quickly but correctly.  Click here for a detailed article on hypothermia from Playak.com.

Proper Paddling Gear

Park Naturalist, Sue Johansen dressed for cold water paddling.

In the world of kayaking we say, “Dress for the water, not for the air.” In the picture above, Devil’s Lake State Park’s naturalist, Sue Johansen is dressed for cold water paddling on Devil’s Lake. She is wearing a drysuit which doesn’t allow water to touch her skin through the suit. Under the drysuit, she’s wearing multiple layers of wicking, insulating materials to stay warm. She is wearing a life jacket specially designed for kayaking /canoeing in that it fits comfortably and will stay on when you fall in the water. (Those cheap orange life jackets will often just fall off when you fall in!) Keeping your hands warm and functioning is imperative to safety. To keep her hands warm, Sue is wearing thick neoprene dive gloves. She also slides her gloved hands into neoprene pogies that wrap around her paddle. Pogies reduce heat lost due to transpiration by protecting your hands from the wind. Sue’s feet are also protected by the drysuit with warm wicking socks underneath. She also wears a pair of thick neoprene boots to add more insulation (And traction on the rocks!).  Even wearing a simple hat will help you hold heat in your body.

Proper clothing doesn’t guarantee safety of course, but will increase your survival time exponentially! With proper gear you will have time to think through your situation and arrive at a good solution which may mean calling for help (If you have a dry phone or radio), getting back into your boat or swimming to shore.

So how long do you have to dress like this to really be safe on the water?  Well, how much of a risk taker are you? You definitely are facing some risk of cold water shock all year in Wisconsin’s lakes and rivers. You do need to get to know yourself as well. Hypothermia can sneak up on you even in warm conditions. Heck, when I circumnavigated Puerto Rico by sea kayak in 2007, the water temperature was around the 80 degree mark and the air was nearly 100f and still with a wind, I’d start feeling cold after hours on the water. There would be nights where I’d be on the beach in my tent, shaking while wrapped in my sleeping bag!  The risk of hypothermia is always there.

The point is, cold water is more dangerous than most people realize. After a long winter here in Wisconsin, many of us want to get on the water desperately and often take more risk than we should. Right now, it’s just too cold to be in without proper gear. And this year, the cold water will remain later into the season due to the cold spring we’ve had.  So, be careful out there. Stay safe!
