The Tacoma-Pierce County Health Department issued a toxic algae advisory for Lake Steilacoom Aug. 29, 2017. That means there are areas of the lake with algae that are unsafe for people and pets.

The advisory means people and pets should avoid areas of the lake where algae is present.

  • Keep children and pets away from areas with algae
  • Do not swim, wade, water ski, or fish in areas with algae

You can easily identify a toxic algae bloom because of its unusual color or appearance in the water. Usually a bloom makes the lake surface look like pea soup or green paint, but sometimes the bloom may be a different color (bluish or brownish). Wind and rain can greatly change the amount and location of algae in the lake.

Swallowing lake water containing algae or prolonged skin contact with the algae may result in illness, such as muscle weakness, vomiting, diarrhea, and/or nausea. Anyone who swallows water containing large amounts of algae should seek immediate medical attention.

The risk to pets is much greater than the risk to people. Pets have smaller body sizes and are more likely to drink water containing a heavy concentration of algae. If a pet ingests a large amount of algae and is showing signs such as vomiting, lethargy, disorientation, or seizures, take it to a veterinarian as soon as possible.

Runoff from fertilizers, animal and human waste reach our lakes and contribute to algae growth. Reducing the use of fertilizers, properly maintaining septic systems, and properly disposing of pet waste helps improve water quality in lakes, streams, groundwater, and Puget Sound.
