In 2012 Saginaw Bay Muck Was Poop


This post was originally published in 2012. It’s one of the most viewed and searched for on ThumbWind.  With the recent budget cuts announced for the EPA by the current administration it’s feared that the Great Lakes and Saginaw Bay will once again experience muck and fecal encrusted beaches.

We were trying to think of a tactful headline for this piece but decided cut to the chase. Huron County lake front owners have known for years that the declining water quality in Saginaw Bay is due to two factors. 1) Outdated and failing septic tanks and overflow from Bay City. 2) Concentrated Animal Feeding Operations CAFOs. Now we have actual experts that confirmed local suspicions of what exactly is in the muck that has been appearing on beaches.

At the 2012 Saginaw Bay Watershed Conference held at Saginaw Valley State University, Marc Werhougstraete, a Michigan State University Department of Fisheries and Wildlife research assistant, said muck means sewage and fecal matter are likely present.

The blue green muck is composed of different types of algae, macrophytes and decomposing organic matter that varies from season to season. In research Werhougstraete conducted at the Bay City State Recreation Area, he found both human and bovine feces (poop) in the muck.

Basically if you see the muck on the beach, think “poop”. Don’t go into the water and don’t let your kids play in the wet sand. “To reduce risk of contracting illness”, said Werhougstraete,  “avoid contact with muck, wash hands when in contact with it and do not submerge your head in the water.”

Common muck management, such as raking, also can release the pathogens from the muck. People cleaning beaches should do so in the morning, when the beaches are less busy and the sun can kill bacteria, Werhougstraete said.

The algae and muck have gotten so bad in recent years it now compares with the situation Lake Erie faced in the 1960s. NASA released pictures shot from the space station that showed the full algae bloom in 2011.

ThumbWind.com is Tracking MUCK Incidents on the Great Lakes


If your beach is awash with fowl smelling green or grey MUCK we want to know about it. We will be tracking MUCK sightings throughout the 2012 summer season and tracking the MUCK flotsam to present to the Lake Huron lake Management Plan (LaMP). LaMP is an organization of USEPA and NGOs, non-profits that focus specifically on Great Lakes water quality. Please fill out the form below.

MSU Microbiologist Confirms Animal & Human Waste in Lake Huron


Bad Axe, Huron County, Michigan – The Huron Daily Tribune reports that during the Huron County Board of Commissioners meeting a report was highlighted by Dr. David Swenson from Michigan State University. Joan Rose,a MSU microbiologist has determined the bacteria in the lake are from both animal and human waste,” said Swenson. “The animal waste is from runoff from area farms and there’s no acceptable reason to have it getting into the lake because there are technologies available to take care of that.”

The news comes just has tourist season begins in the Upper Thumb. This report comes on the heels of earlier story’s at ThumbWind of Algae Blooms that can be seen from space and the problem of muck in Saginaw Bay.
