RAPIDS
- Generally, rapids in the BWCAW are not safe to “run”, so use the provided portages.
- Powerful currents can trap swimmers under water, or sweep them towards dangerous waterfalls.
- Fast moving water can push swimmers and boats into rocks and logs.
- Even with lifejackets on, rapids are dangerous.
WATER QUALITY
- Giardia lambia is a parasite that can cause an internal illness that will need medical attention.
- All drinking water should be treated by one of the following methods:
- 1. Bring water to a full boil for 3 to 5 minutes — then let stand until cool enough to drink.
- 2. Purify with a filter specifically designed to remove Giardia lambia.
- 3. Treat water with a chemical specifically designed to kill Giardia lambia.
FISH
- Chemicals such as mercury, PCBs, and dioxin have been found in some fish from certain waters.
- Eat more pan fish and fewer predator fish, as well as trim the skin and fat, to reduce your risk.
- Check with the Minnesota Department of Public Health for current information on limits on fish consumption at (651) 201-4911.
HYPOTHERMIA
- A low body temperature can be serious, even fatal.
- Early warning signs are uncontrolled shivering, slurred speech, bluish tinge to lips, lack of coordination, and poor concentration.
- To prevent hypothermia, layer clothing and get adequate food and water.
- To treat hypothermia, seek shelter from the wind, replace any wet clothing, and share body heat if necessary.
- Give warm fluids if the person is conscious and have them rest until thoroughly warmed.
FIRST AID/EMERGENCIES
- Each permitted group should carry a well stocked first aid kit and have group members that know how to provide first aid.
- Please note that the campsite number is painted on the latrine of most campsites. Also note the location of the lake, campsite, trail or portage on a map to help emergency people locate any seriously injured party.
- Document the extent of the injury and a basic physical description of the injured person in need.
- Send all of this information with visitors able to exit the BWCAW for help.
- Do not rely on a cell phone. Having a cell phone cannot substitute for knowing how to handle an emergency in wilderness. Many areas of the BWCAW lack cell phone coverage.
- In the event of serious injury or illness, the standard SOS call is a series of three signals of any kind, either audible or visible.
- For summoning help from an aircraft in an emergency, signal them by paddling in small circles or waving a brightly colored cloth tied to the canoe paddle.
TRAVEL
- There are no directional signs in wilderness.
- A compass and accurate map are essential.
- Most visitors prefer using Fisher or McKenzie maps which can be purchased at some Forest Service offices, area businesses and outfitters, or directly from the map companies—see page 8 for details.
- If you get lost, don’t panic. Sit down, relax, and think. Chances are that you will figure out your location in a few minutes.
- If you plan to use a Global Positioning System (GPS) for navigating, be sure you also bring a map and compass as a back up in case your GPS unit fails.
WEATHER
- Canoe close to shore. It lessens the chance of being endangered by sudden changes of weather. If a storm threatens, get off the water.
- Dress in layers and be prepared for every kind of weather situation.
- If in a lightening storm on the water, get to shore. If on land among trees of similar height, put yourself an equivalent distance between two trees. Avoid the tallest trees.
- Avoid being a bridge between an object and the ground. For example, do not lean against tent poles or trees.
- Avoid potential paths of conduction such as wet, lichen-covered rocks, cracks and crevices (wet or dry), and areas subject to the “spark gap” such as overhangs, wet ropes, and tree roots.
- If your skin tingles, or your hair stands on end, stand on a lifejacket or sleeping bag, squat low to the ground on the balls of your feet.
- Place your hands on your knees with your head between them. Make yourself the smallest target possible, and minimize your contact with the ground.
DEHYDRATION
- The body becomes dehydrated when more fluids are lost than replaced.
- Drink plenty of water.
- Signs of dehydration include headache, cold and flu symptoms, and infrequent urination.
CAMPING WITH BEARS
- Keep a clean campsite. Never eat or store food in your tent.
- Take all precautions to discourage bears from visiting your site, including hanging your food pack, as well as garbage and anything that has a strong or sweet odor (soap, toothpaste, etc.).
- Some bears overcome their fear of humans and approach campsites looking for food. This includes island sites since bears are good swimmers.
- If you do encounter a bear, most will be scared off if you make noise (shout, bang pots, or throw fist-sized rocks at the bear, etc.).
- A very persistent bear may be discouraged by spraying pepper spray into its eyes.
