Toxic algae in King County Lakes: Due to toxic algae blooms, Public Health recommends that humans and pets stay away from the water in King County lakes where algae is visible. Follow all posted guidance at parks at beaches. If your pet goes in or near the water at a King County lake, we recommend monitoring them for these symptoms: low energy, not eating, vomiting, diarrhea, difficulty breathing, or seizures. Symptoms will typically occur within minutes to hours after exposure. If your pet becomes ill, call your veterinarian immediately.
