Algae Blooms

Researchers still don't know much about didymo or "rock snot," a microscopic algae that can bloom into thick, slimy mats on rivers.

Researchers are projecting the cyanobacterial bloom in the western basin of Lake Erie won’t be as bad as last year.

Harmful algal blooms may leave lakes with a bright green or oily surface... it’s caused by an overgrowth of toxic cyanobacteria. Climate change is projected to increase blooms and expand their presence across Michigan.

An invasive species that threatens rivers and streams has been spotted in the Boardman River, near Traverse City.It’s called “didymo,” but it also has an unappetizing nickname: Rock snot.

A new resource is available for Michigan residents and visitors to be more aware of toxic algal blooms on lakes.

The discovery marks the first time didymo has been found in the lower peninsula.
