Toxic algae detected in Pierce County lake, health officials say. Keep pets away
Editor’s note: The advisory was lifted Nov. 25, 2024.
Toxic algae has been detected in parts of Tanwax Lake, according to the Tacoma-Pierce County Health Department.
An advisory was issued on Friday to caution the public of the toxic algae, the health department said in a news release.
People and pets should not swim, wade, waterski or fish in areas where algae is visible as they pose health risks. There are signs posted at the lake to inform people of the advisory, the release said.
“Keep in mind as wind direction changes, the algae could move elsewhere in the lake. When in doubt, stay out!” the release said.
The lake was sampled on Oct. 15. The health department will sample the lake again next week.
Cynobacteria, mostly commonly known as toxic algae, occur naturally in lakes.
“Toxic algae can form a scum layer and look like green pea soup. They can also look streaky, be dispersed in the water column, or form clumps,” the release said.
Algae can come in different colors. They are often green, but can also be brown, red and blueish.
The toxins of toxic algae can make people, pets and animals sick, the release said. Some symptoms include muscle weakness, vomiting, diarrhea and nausea, the release said.
More information on toxic algae is available on the health department’s website.
