Michigan trying new approaches against invasive crayfish

By Elinor Epperson

Researchers are exploring new techniques to remove an invasive crayfish from Michigan waters. The Michigan Department of Natural Resources has been fighting an invasion of red swamp crayfish since they first appeared in the state in 2017. Aggressive attempts to trap and remove the crustacean haven’t worked. Kathleen Quebedeaux, a fisheries biologist with the DNR, said eradicating the invader will require a variety of approaches. “In order to have a more efficient means of achieving eradication, we need other tools in our toolbox,” she said.

Community input sought for cleaned-up lakes, shorelines

It’s taken over 30 years and $80 million to restore Muskegon Lake and a few nearby smaller bodies of water.

Decades of pollution and rapid urbanization created ecological problems so severe that the lake was designated a “Great Lakes Area of Concern” by the U.S. and Canada in 1987.

Old Lake Michigan shipwreck visible again after burial under sand

Look fast or you may miss an elusive 170-year-old sunken schooner off the coast of Baileys Harbor, Wisconsin.

The mostly intact shipwreck, which was added to the National Register of Historic Places in early April, isn’t always visible, even though it’s in very shallow waters, said Tamara Thomsen, a Wisconsin Historical Society maritime archaeologist.

Covering watershed policy and identity

The Mississippi River Basin and the Great Lakes-St. Lawrence River Basin supply freshwater and drain wastewater for millions of people.

Two of the largest watersheds in the U.S., they span state and political boundaries. 

An underappreciated lake that’s great

Sitting at 26 miles long and 24 miles wide with nearly one-third of the sport fishing catch annually in the Great Lakes region, Lake St. Clair should be a household name.
