Health department issues toxic-algae advisory for Ohop Lake

The Tacoma-Pierce County Health Department issued a toxic algae Caution Advisory for Ohop Lake Friday after sampling the lake Sept. 7. Residents are advised to avoid areas of the lake where algae can be seen because it can pose health concerns for people and especially pets. Signs have been posted at the lake to let people know.

Residents who see algae should not swim, wade, waterski or fish and should be aware of wind changes that might push the algae elsewhere. Pets are especially at risk

Health department staff will inspect the lake again this week, and if the bloom is no longer there, the advisory will be left in place for two weeks out of caution.
