  • If you or your child seems ill after being in water with an algal bloom, get medical attention immediately. Symptoms include loss of appetite, vomiting, diarrhea, cough, difficulty breathing, sore throat, itchy skin, or rash.
  • If your pet appears to stumble, stagger, or collapse after being in a pond, lake, or river, see a veterinarian immediately.

It is recommended that all lake users check for visual signs that an overgrowth is occurring before coming into contact with water. Visual signs of an overgrowth may include bright green, blue, discolored, and / or frothy water. If visual signs are observed, follow the above safety measures.
