Stay clear of these areas if you are an inexperienced swimmer. Parents and guardians must keep a constant watch on small children and non-swimmers in their care. It takes only a few seconds of inattention for a drowning to occur. In the early summer, when water temperatures are still cool, hypothermia is a serious risk to bathers. Swimmers can rapidly lose vital body heat and become mentally and physically impaired.
Water quality can change rapidly.
Storms and the resulting run-off from rivers and streams can temporally contaminate the lake. Most lifeguarded beaches are routinely monitored for water quality. Watch for posted signs indicating water quality, or check with a lifeguard or beach manager if in doubt. Consumption of alcoholic beverages can impair judgement and increase the risk of drowning. Swimming and alcohol are a deadly mix.
