Currents can be strong and drown even the best swimmer. If unsure of the conditions or your swimming ability, make sure to wear a personal floatation device. Alcohol can affect your ability to handle a canoe and swimming ability and so it is best to pick a relatively slow river if drinking and floating. Also be aware of water depth and debris when jumping into water. If fishing, be careful with hooks.
Lures caught in trees or rocks can come loose when yanked and fly at high speeds.
Some fish such as catfish have sharp barbs. Catfish have one barb on top and two on the sides. Some colder weather hazards are hypothermia and frostbite. Hypothermia occurs when the body s core temperature drops to a level where muscles and the human mind do not work as intended. This condition can be harmful or fatal if not treated by warming the body up to normal temperature.
