    People should avoid swimming and high-speed water activities, such as water skiing or power boating, in areas where blooms are identified. Children and pets are at increased risk for exposure because of their size and level of activity. People who bring their pets to Detroit Lake for recreation activities should take special precautions to keep them from drinking from or swimming in the lake. Drinking water from the lake is especially dangerous. Cyanotoxins cannot be removed by boiling, filtering or treating water with camping-style filters.
