Didymo found in Upper Manistee River


The Michigan departments of Environment has confirmed a report of didymo, aka “rock snot”alga, in a stretch of the Upper Manistee River. The Manistee River finding marks the first detection of didymo blooms in the Lower Peninsula. In 2015, extensive mats of didymo were found on the Michigan side of the St. Marys River near Sault Ste. Marie in the Upper Peninsula.

“We’re taking this very seriously,” said Bill Keiper, an aquatic biologist with the Michigan Department of Environment, Great Lakes and Energy. “Our sense is it could invade any cold water stream we have in the state.”
