Black Lake algae scum smelly, non-toxic

Staff writerAugust 22, 2013 

Algae scum is collecting on the north end of Black Lake, creating a smell but no toxins to date, according to the Thurston County Environmental Health Department.

Severe algae bloom has been occurring on Black Lake, according to Sue Davis of the county environmental health division. As a result, algae scum has been pushed to the north end of the lake by wind and is decomposing.

The health department takes samples weekly, but has not detected any toxins. Regardless, Davis urged those who frequent the lake to avoid swimming in areas where algae scum is on the surface or where there is so much algae in the water that they cannot see their feet while wading.

Children and pets should especially be kept away from algae areas, Davis said.
