MACKINAC COUNTY – The LMAS District Health Department was notified by the Michigan Department of Health and Human Services that an algal bloom suspected to be blue-green algae, also known as cyanobacteria, or harmful algal blooms, was detected on the Brevort Lake near the north shore shore in Mackinac County.
Samples will be sent to the MDHHS laboratory for testing.
LMAS is recommending residents and visitors of the lake avoid water-related activities and keep pets from drinking or going in the lake water, in the area where the bloom is visible until sampling for testing is complete, or the bloom breaks up.
Advisory signs have been posted at public access points around the lake.
It is not possible to determine whether algal blooms contain harmful toxins by looking at them, so it is best to avoid contact with any body of water that is covered with algal scums, mats or significant rafts of algae on the surface.
