Rip Currents can also occur in waters adjacent to seawalls, artificial reefs, and erosion control structures. 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.
