The 7-acre (2.8 ha) island is administered locally by Grosse Ile Township.
Added in 2002, Calf Island was one of the newer additions to the Detroit River International Wildlife Refuge.
Under the refuge, the Michigan Department of Natural Resources and Ontario Ministry of Natural Resources identifies more than 29 species of waterfowl and 65 kinds of fish that make their home in and around the waters of Calf Island.
The island often serves as a nesting location for a small number of herons.
