The Tacoma-Pierce County Health Department issued a Toxic Algae Advisory for Lake Steilacoom on Tuesday, Oct. 11.

When you see a toxic algae advisory, it means the water has cyanobacteria, or blue-green algae, which can produce toxins. Add sunlight and warmer temperatures, and toxic algae can reproduce rapidly in fresh water—creating toxic algae “blooms.” Water with toxic algae can kill pets, waterfowl and other animals and cause serious illness or even death in people.

Until further notice, TPCHD says residents must:

  • Not swim or water ski in areas of scum
  • Not drink lake water
  • Keep pets and livestock away
  • Clean fish well and discard guts
  • Avoid areas of scum while boating
