The following is a description of islands in the Detroit River. The Detroit River is a major waterway in the Great Lakes system, and it flows for 24 nautical miles (44 km; 28 mi) from Lake St. Clair south to Lake Erie. The river serves as a major shipping channel, jointly controlled by the United States and Canada, and it is a major component of the Canada–United States border. The majority of islands are on the American side of the river, which are all within Wayne County in Michigan. The Canadian islands are part of Essex County in Ontario. There are no islands in the Detroit River that are divided by the international border, as Michigan and Ontario share no land borders at any point.
Most of the islands are very small and uninhabited, and many of these islands around the southern portion of the river serve as nature reserves as part of the Detroit River International Wildlife Refuge. The largest and most populated island is Grosse Ile, and many islands are part of Grosse Ile Township. Several islands were also artificially created by canals, such as several islands within the city of Gibraltar, as well as Elizabeth Park and Zug Island.

Main article: Belle Isle Park (Michigan) |
Belle Isle (42°20′35″N 82°58′28″W / 42.34306°N 82.97444°W) is a 982-acre (3.97 km2) island in the northeastern portion of the Detroit River just north of Downtown Detroit. Belle Isle sits at an elevation of 574 feet (175 m) above sea level, and the island has also gone by several historic names.[1] It is the northernmost island in the river just downstream from Lake St. Clair. Because of the curve in the river, Belle Isle is just west of (Southbound on the river) the Canadian Peche Island, which is the easternmost and first island in the river heading South. It is the third-largest island in the river after Grosse Ile and Fighting Island. The island is within the city limits of Detroit but is administered by the Michigan Department of Natural Resources, as the island was designated as a state park named Belle Isle Park in 2014.[2] The island is connected to the mainland by the MacArthur Bridge, which carries East Grand Boulevard and connects to East Jefferson Avenue. Belle Isle has no permanent population.
The island is a very popular tourist destination that contains a number of historic structures and events. The entire island is listed as a historic district on the National Register of Historic Places and also as a Michigan State Historic Site. The island itself also contains several lakes, including the Blue Heron Lagoon, Lake Muskoday, Lake Okonoda, Lake Takoma, and several artificial canals. These lakes also contain several unnamed recursive islands (islands within an island).[3]

Beginning in the 1880s, Sugar Island became a popular resort location, and it eventually contained an amusement park and other entertainment venues. Ferry services brought guest to and from the island until the 1940s when the amusement park closed. The island soon fell into disuse and ruins. In 2012, the deserted island was purchased by the United States Fish and Wildlife Service and soon after included as a unit in the Detroit River International Wildlife Refuge. The island contains no structures, and access to the island is restricted.[42]

Main article: Bois Blanc Island (Ontario) |
Bois Blanc Island (42°05′50″N 83°07′16″W / 42.09722°N 83.12111°W), popularly known as Boblo Island, is a 274-acre (1.11 km2) island in the southeast portion of the Detroit River. It is the southernmost Canadian island in the river and is administered by the town of Amherstburg.
In 1836, the Bois Blanc Island Lighthouse and Blockhouse were constructed on the island as an aid to navigation at the mouth of the Detroit River. The island then served as a military outpost.[46] The lighthouse was decommissioned in the late 1950s, but the structures remain to this day.[47] The island is most famously known as the location for the Boblo Island Amusement Park, which operated from 1898 to 1993. Ferries services routinely brought Americans to the island from the Boblo Island Detroit Dock further upstream. The island has no bridges connecting to the mainland; local ferries continue to serve the residents that now live in upscale housing on the northside of the island. The southside, where the amusement park once stood, remains undeveloped. The island is accessible to the public.[48]
Crystal Island (42°07′21″N 83°07′17″W / 42.12250°N 83.12139°W) is an artificial island located directly across the international border from Stony Island.[6] Though it is uninhabited, it is part of the town of Amherstburg. Similar to Stony Island, it was created to provide and mark a deeper shipping lane, and the island has a very irregular shape. Crystal Island's odd shape created a pristine inlet known as Crystal Bay. The small bay is protected by the island from the river's current and pollution, thus creating an unusually calm and clear shelter. While the island itself is off limits since it serves as a nature preserve, the bay is a popular destination for boaters and fishermen.[49][50][51]

Main article: Fighting Island |
Fighting Island (42°13′18″N 83°07′12″W / 42.22167°N 83.12000°W) is the largest Canadian island in the Detroit River at 1,500 acres (6.07 km2). It is the second largest island in the river after Grosse Ile.[6] Fighting Island is administered by the town of LaSalle, but it is privately owned by the German-based BASF, which has a facility across the river in Wyandotte.
The island originally had a small indigenous population before it was purchased by the Michigan Alkali Company in 1918. The company used the island as a dumping ground for waste. The island served as a dumping ground until at least 1982. In 1989, it was reported that 80% of the island was covered in highly acidic brine waste, which also caused dust clouds to travel to nearby communities. BASF purchased the company (by then Wyandotte Chemical Company) in the early 1970s,[52] and has since done a large-scale cleanup and restoration of the island. The island remains undeveloped and serves as a growing nature refuge and educational retreat.[53][54]
Grass Island (42°13′17″N 83°06′30″W / 42.22139°N 83.10833°W) is an extremely narrow and elongated island between Fighting Island and mainland LaSalle, which administers the island.[6] The island is uninhabited and undeveloped. The island is sometimes referred to as Grassy Island, which is an American island on the exact opposite side of the river.[55]

Main article: Peche Island |
Peche Island (42°20′45″N 82°55′31″W / 42.34583°N 82.92528°W) is an 86-acre (34.8 ha) island at the very beginning of the Detroit River at Lake St. Clair. It is within the city of Windsor. It is the easternmost island in the river and is just east of Belle Isle. Peche Island was historically known by its French names Isle aux Pêcheurs (Fisherman Island) and Isle a la Pêche (Fishing Island), but it was sometimes referred to as Peach Island due to the English pronunciation.[56][57]
The island was originally privately owned and used as a lavish summer residence for Hiram Walker and later others. Later owners attempted to profit and turn the island into an amusement park and resort destination similar to Belle Isle and Boblo Island Amusement Park, but these plans never came to fruition. The island was eventually sold to the Province of Ontario and converted into a provincial park in 1974, but the island had no future plans. The City of Windsor purchased the unused island in 1999. The island has since remained undeveloped and serves as a nature preserve and city park.[57][58]
Turkey Island (42°11′09″N 83°06′48″W / 42.18583°N 83.11333°W) is a small uninhabited island just south of Fighting Island. The island is within the town of Amherstburg. The island is privately owned, inaccessible, and undeveloped.[6]
