Health Advisory at Pattison Lake

This advisory has been lifted.

There is currently a health advisory for blue-green algae toxicity on Pattison Lake. 

Residents and lake users are advised to:
  •         Avoid recreational contact with the lake.
  •         Keep pets out of the water.  
  •         If fishing, catch and release is the safest practice.

Preliminary results from a water sample collected on August 21 from a site off Atchinson Drive on the south basin of the lake show that the toxin, microcystin, is above the recreational advisory limit of 6 µg/L. The preliminary result reported is 16 µg/L.   

Thurston County Environmental Health requests that Pattison Lake volunteers post advisory signs at your community areas.  Thurston County Environmental Health will post signs at the public launch, and will monitor the lake weekly while the bloom is present. 

If you have questions, contact Cathy Hansen at (360) 867-2645.
