  • Grassy Island: Detroit River International Wildlife Refuge
    U.S. Fish & Wildlife Service Grassy Island: Detroit River International Wildlife Refuge Frequently Asked Questions Where is Grassy Island? Grassy Island is located in the Detroit River, approximately 10 miles downstream from downtown Detroit, just east of the City of Wyandotte, west of Fighting Island (Ontario, Canada), and north of Grosse Ile. How did it become contaminated and what is the extent? Originally, Grassy Island was a large shoal area with a few low-lying islands. The U.S. Army Corps’ of Engineers (USACE) built dikes around 72 acres of this area to create a disposal location for sediments dredged primarily from the Rouge River. From 1959 through 1987, the USACE disposed of over three million cubic yards of dredged sediments on Grassy Island. There are 28 contaminants in the soil that exceed state and federal guidelines and criteria, including heavy metals (e.g. mercury and lead), polychlorinated biphenyls, and polynuclear aromatic hydrocarbons (e.g. oil and grease components). What is the role of the U.S. Fish and Wildlife Service? Grassy Island is owned by the U.S. Fish and Wildlife Service (Service), has been part of our Refuge system since 1961, and is now part of the Detroit River International Wildlife Refuge (DRIWR). As the island’s owner, the Service is authorized to be the lead agency for conducting investigations and response activities. The Service is also responsible for making final clean up decisions with Michigan Department of Environmental Quality (MDEQ) concurrence. The Service is committed to meeting our cleanup responsibilities in a manner that results in Grassy Island meeting some DRIWR purpose and broad goals.

The event drew an audience of approximately 60 attendees and speakers. The purpose of the forum was to review what was known and unknown about Grassy Island, receive public input, clarify roles and responsibilities of the parties involved, and to develop a list of short-term actions that would complete the investigative phase and move forward in a coordinated fashion amongst the partners toward the goal of restoring Grassy Island. To receive more information about Grassy Island, go to: http://www.fws.gov/midwest/grassyisland This discussion record contains summaries of the key discussions and conclusions from the presentations, panel discussions, and public comments regarding Grassy Island. Grassy Island Forum Report December 1, 2005; Wyandotte, MI PRESENTATIONS: An Historical Perspective of Grassy Island Dr. Bruce Manny, U.S. Geological Survey (USGS) Grassy Island appears on a 1796 map of Detroit River and was called “Ile Maricageuse” (Marshy Island). The first known use of Grassy Island was for commercial fishing purposes. An 1873 fisheries report indicates that spawning whitefish were seined in on the island, producing 45,000 adult whitefish per season. In the late 1800s, the U.S. Coast Guard installed navigational lights (lighted towers) near the island for ships down bound in the Fighting Island Channel The U.S.
