Scientists and engineers are working together to design a clean-up plan for Michigan’s Upper Trenton Channel, where high concentrations of historic pollutants pose a threat to aquatic life and public health. The process began about a year ago with a feasibility study. In January, local residents had a chance to weigh-in on an early draft of the plan. And in the coming years, this Great Lakes Legacy Act project could remove or cap around 240,000 cubic yards of contaminated sediment.  
 
Just as important as the clean-up effort itself, is ensuring that local communities and other key stakeholders understand the project and its goals. But before they can begin public outreach, project partners have to understand and appreciate the role the channel and nearby Detroit River play in the communities. 
 
That is where IISG’s social scientist Caitie McCoy and her interns Erika Lower and Mark Krupa come in. The three were in Michigan earlier this month to conduct a needs assessment that will help the project team tailor outreach products and messaging to those who use and visit the river.
 
They interviewed around 35 people with diverse backgrounds—everyone from area residents to city planners to members of boating associations—to learn more about their perceptions of the channel and river. The final results of the study won’t be available for a few months, but the interviews have already given Caitie, Erika, and Mark a better understanding of the interests and concerns surrounding this popular recreation site.
 
“One interesting thing we learned was that the safety of the channel and river during dredging is of prime importance to the community,” said Caitie. “This is a fast flowing channel, and we will need to explain the science and engineering behind what keeps stirred up sediment from flowing downstream during the project—in terms that everyone can understand.”
 


An impromptu trip on the channel also gave Caitie, Erika, and Mark deeper insight into how the community uses the channel and river. The trip—which set off bright and early on the 16th—was led by the Wyandotte Rowing Club. Later that night, the group took to the water once again with one of the residents they interviewed.  
 
Similar studies for the Sheboygan River and St. Louis River Areas of Concern have already helped shape outreach efforts there and allowed project partners to gauge changes in community perceptions at the end of a clean-up project.
 
The Upper Trenton Channel, which sits about 20 miles south of Detroit, is part of the Detroit River AOC. Project partners include Michigan Sea Grant, Friends of the Detroit River, the Detroit River Public Advisory Council, the Michigan Department of Environmental Quality, the Michigan Department of Community Health, and the U.S. EPA.

Looking for a fun way to teach about marine debris? Check out Me and Debry, which is a whimsical, 30‑minute, audience‑participation play created for @UWiscSeaGrant. It helps students explore what marine debris is, why it matters, and how we can make a difference in the Great Lakes.The full script (English) and participation scripts (English, Spanish, and Hmong) are free to use, along with marketing materials for performances.Bring learning to life and start a conversation about litter in our waters!Check it out at the link in bio.#TeachingTuesday
Do you work or live along the Great Lakes coasts? Watch our newly released video series collection, containing several short videos that overview the range of coastal protection options in the Great Lakes, including:- Natural processes in the Great Lakes- Hard coastal protection structures and how they interact with/alter natural processes- Nature-based coastal solutions in the Great Lakes, ranging from green to gray approachesFind our two new video series at the link in bio.
Located in Washington, D.C., the Sea Grant Knauss Fellowship provides a unique educational and professional experience to graduate students who have an interest in ocean, coastal and Great Lakes resources, and in the national policy decisions affecting those resources. This is a one-year fellowship open to any student, regardless of citizenship, who is enrolled toward a degree in a graduate or professional program on the day of the deadline.Students enrolled at an Illinois or Indiana university or college should submit their applications through Illinois-Indiana Sea Grant by emailing Angela Archer at amcbride@purdue.edu. Students in surrounding states without a Sea Grant program should contact the National Sea Grant College Program at oar.sg.fellows@noaa.gov for a referral. Application deadline: June 3, 2026.To learn more about the fellowship, visit the link in bio.
