Report health concerns

If you live near a lake or visit lakes, please watch for cyanobacteria blooms. Blooms can make a lake look green and cloudy. Green, blue, or white scum, foam, or matting may form on the water’s surface, and may look like paint floating on the water.

Stay out of the water and contact the Health District at 360-728-2235 if you see a bloom or notice any of the following: 

• Large numbers of dead fish.
• Sudden or unexplained sickness or death of an animal that has just drank or swam in lake water.
• If someone enters the water and experiences skin rash, dizziness or weakness, respiratory allergy, abdominal pain, diarrhea, or vomiting.
