The river, which forms part of the border between the U.S. state of Michigan and the Canadian province of Ontario , flows west and south for 24 nautical miles (44 km; 28 mi) from Lake St. Clair to Lake Erie as a strait in the Great Lakes system. The river divides the metropolitan areas of Detroit , Michigan , and Windsor , Ontario —an area collectively referred to as Detroit–Windsor . The Ambassador Bridge ,

138-620: A Canadian Heritage River .  It is the only river in North America to have such dual designations. In 2001, the Wyandotte National Wildlife Refuge was absorbed into the larger Detroit River International Wildlife Refuge , a cooperative effort between the United States and Canada to preserve the area as an ecological refuge. The millions of dollars spent since that time to dredge pollutants out of

207-476: A river and a strait  — a strait being a narrow passageway connecting two large bodies of water, which is how the river earned its name from early French settlers. However, today, the Detroit River is rarely referred to as a strait, because bodies of water referred to as straits are typically much wider relative to their length. The river forms the southern portion of the waterway connecting Lake Huron to

276-568: A classical nude woman was originally installed to overlook a reflecting pool in the Grosse Pointe War Memorial . It was nicknamed "The Nude," and, in 2001, was believed to have been successfully stolen for display in some art collector's private cache.

Other fish caught by recreational fisherman include white bass , bluegill , crappie , freshwater drum , smallmouth bass , northern pike and muskie . There are over 800,000 recreation boats in Michigan, and more than half of them are regularly used on or near the Detroit River. Popular river destinations in Detroit include

690-563: Is four times longer than the Detroit River and contains most of the watershed. The only other major American tributary to the Detroit River is the much smaller Ecorse River . Tributaries on the Canadian side include Little River, Turkey Creek, and the River Canard . The discharge for the Detroit River is relatively high for a river of its size. The river's discharge averaged over the year is 5,300 m/s (190,000 cu ft/s), and

759-520: Is on the banks of the Detroit River. According to a 2004 study, 150,000 jobs and $ 13 billion in annual production depend on the river crossings connecting Detroit to Windsor. In 2004, the American trade with Ontario alone was $ 407 billion, in which 28% ($ 113.3 billion) crossed the Detroit River. There are two automobile traffic routes that completely cross the river: the Detroit–Windsor tunnel and

It is an important transportation route connecting Lake Michigan , Lake Huron , and Lake Superior to Lake Erie and eventually to Lake Ontario ,

1035-479: The North American fur trade intensified, European settlers expanded their trade westward into uncharted territories. French explorer Antoine Laumet de La Mothe, sieur de Cadillac sailed up the Detroit River on July 23, 1701. The next day, he established Fort Pontchartrain du Détroit , which developed as Detroit. The French named the river as Rivière Détroit . Détroit is French for " strait ". The river

1104-553: The St. Lawrence Seaway and the Erie Canal . When Detroit underwent rapid industrialization at the turn of the 20th century, the Detroit River became notoriously polluted and toxic. Since the late 20th century, however, a vast restoration effort has been undertaken because of the river's ecological importance. In the early 21st century, the river today has a wide variety of economic and recreational uses. There are numerous islands in

1173-632: The St. Lawrence Seaway or the Erie Canal to New York City . At the beginning of the 20th century, the automotive industry boomed, and the many manufacturers imported abundant supplies of iron ore , sand, limestone and wood. The Detroit River provides substantial revenue for the local economies. A 1991 study showed $ 20.1 million came from sales related to waterfowl hunting along the Detroit River. The same year, bird watching, photography, and other non-consumptive uses of waterfowl contributed another $ 192.8 million to Michigan's economy. Local economies benefit through boating registrations and fishing licenses. It

1587-548: The Canadian border region also assisted Blacks hoping to flee from the U.S. once the Fugitive Slave Act was strengthened in 1850. Canada also granted legal immigration status to Blacks, while Mexico did not for many years. Individuals and organizations assisted escaping slaves hoping to cross the Detroit River from the United States into Canada. The Second Baptist Church of Detroit and First Baptist Church of Amherstburg coordinated ferrying thousands of Blacks across

1656-726: The Detroit River , and much of the lower portion of the river is part of the Detroit River International Wildlife Refuge . The portion of the river in the city of Detroit has been organized into the Detroit International Riverfront and the William G. Milliken State Park and Harbor . The Detroit River is designated both an American Heritage River and a Canadian Heritage River —the only river to have this dual designation. The Detroit River flows for 28  mi (45  km ) from Lake St. Clair to Lake Erie . By definition, this classifies it as both

1725-412: The Detroit River but the term "Downriver" refers broadly to the cluster of 18 suburban communities that lie to the southwest of the city of Detroit and to the west of the Detroit River. The Detroit River contains 31 charted islands. The majority of the islands are located on the American side of the river. Many of the islands are small and uninhabited, and none are divided by the international border, as

1794-469: The Detroit River has led to a remarkable restoration, although problems remain. Today, many species of native animals that had been driven out by human development are returning to the area. The river is home to a growing number of bird species such as eagles (including reintroduced bald eagles ), ospreys , and peregrine falcons . Large numbers of lake whitefish , sturgeon , silver bass , black bass , salmon , perch , and walleye are again thriving in

Famous abolitionists and Underground Railroad conductors including George DeBaptiste and William Lambert worked individually and with these organizations to assist fleeing slaves and condemn slavery.   There was considerable transnational fluidity between the Canadian and American sides of

1932-409: The Detroit River is urbanized and, in some places, has been used for industrial purposes for more than 100 years. There has been excessive water pollution of the river from the long-term, unregulated dumping of chemicals, industrial waste, garbage, and sewage. Much of the Detroit River and its shoreline were polluted and unsafe for recreational use. Thousands of migrating birds died each year because of

2001-503: The Detroit River, and Lake Erie. Finally, a massive conservation effort was initiated to clean up the Detroit River. For years, the multi-million dollar cost of removing pollutants from the river and the political influence of nearby industries, hindered conservation efforts. In 1998, the Detroit River was designated as an American Heritage River by the US Environmental Protection Agency and in 2001 as

2070-493: The Detroit River. Sources of pollution include municipal and industrial discharges, sewer overflows, and several nonpoint source pollution (e.g., storm water runoff). These activities contaminated river sediments and water with polychlorinated biphenyls (PCBs), heavy metals (e.g., mercury), polycyclic aromatic hydrocarbons (PAHs), oil and grease. These contaminants are known to be harmful to fish and wildlife and affect recreational activities. A 2008 remedial action plan for

There are 43 AOCs in the Great Lakes Basin total, with the rest in Canada or shared by the two countries. Over 50% of the land surrounding

2415-509: The River Rouge is used for residential, industrial, and commercial purposes and development pressure continues to increase. Consequently, the river is highly polluted and was designated as a Great Lakes Area of Concern under the Great Lakes Water Quality Agreement in 1987. The designated AOC covers the entire River Rouge watershed including 48 communities that drain 466 square miles of southeastern Michigan into

2484-621: The Rouge was formed and began organizing an annual cleanup called Rouge Rescue, to raise awareness about the need to clean up the Rouge. In 1987, the entire watershed was designated a Great Lakes "area of concern" under the Great Lakes Water Quality Agreement. In 1992, a massive project called the Rouge River National Wet Weather Demonstration Project was implemented, and further cleanup measures are ongoing. The Alliance of Rouge Communities

A DMC DeLorean has also been recovered from the river. The artifacts recovered are well preserved due to the river's fresh water but low visibility makes them difficult to find. A 1940s-era bronze statue depicting

2691-482: The boundary with Dearborn. The lower branch joins less than two miles (3 km) downstream in Dearborn. The lower 1.5 miles (2.4 km) of the river south of Michigan Avenue were channelized, widened, and dredged to allow freighter access to Ford's River Rouge Plant inland factory facilities. The plant was built between 1915 and 1927. It was the first manufacturing facility for automobiles that included within

2760-515: The center of a new industry known as rum-running , smuggling liquor into the US. No bridges connected Ontario, Canada and Michigan, US, until the Ambassador Bridge was finished in 1929 and the Detroit–Windsor Tunnel in 1930. Smugglers used boats of varying sizes to transport alcohol across the river during the summer, and during the winter months, rum-runners traveled back and forth across

2829-571: The city of Detroit is directly north of the city of Windsor, Ontario . The only other location where this occurs is Fort Erie, Ontario , which lies south of several cities in Niagara County, New York . The cities and communities southwest of Detroit along the American side of the river are popularly referred to as the Downriver area, because those areas are said to be "down the river" from Detroit. Several of these communities do not border

Other communities in the lower branch watershed include Van Buren Township , Plymouth Township , Salem Township , Ypsilanti Township . Tributaries include (from downriver to upriver): The U.S.-Canada Great Lakes Water Quality Agreement defines an Area of Concern (AOC) as “geographic areas designated by

3381-562: The most accessible rivers in the state. Until recently the river was heavily polluted, and in 1969 oil on the surface caught fire. The passage of the Clean Water Act in 1972 made it unlawful to discharge any pollution from a point source into navigable waters, and the EPA's National Pollution Discharge Elimination Program was created to regulate these discharges. In 1986, a non-profit organization of concerned citizens called Friends of

3450-457: The north and Lake Erie to the south, with other portions including the St. Clair River and Lake St. Clair . The Detroit River is only 0.5–2.5 miles (0.8–4.0 km) wide.

3588-410: The oil slicks and contaminated water around the mouth of the Detroit River at Lake Erie . The river's oxygen levels were depleted to the point where fish could not inhabit its waters. Because this pollution often drained into and affected Lake Erie, the lake was considered "dead" and unable to support aquatic life. In 1961, a congressional order founded the Wyandotte National Wildlife Refuge. That began

3657-465: The plant virtually everything needed to produce the cars: blast furnaces, an open hearth mill, a steel rolling mill, a glass plant, a huge power plant, and an assembly line. During the 1930s, some 100,000 workers were employed here. The plant has been designated as a National Historic Landmark . The headwaters of the main branch rise in the southwest corner of Rochester Hills and the northeast corner of Bloomfield Township . It flows mostly south through

3726-481: The privately owned Ambassador Bridge , both of which connect Detroit, Michigan, to Windsor, Ontario.

The largest city along the Detroit River is Detroit , and most of the population along

4002-542: The river. The Detroit River and its recovery efforts were listed as a Michigan State Historic Site in 2007. A historic marker was erected along the river in a park that now serves as the Detroit River International Wildlife Refuge visitor center in the city of Trenton . The Detroit River is used for shipping and trading. The earliest use of the river for these economic activities was the shipping of furs for trade as early as

4071-580: The river. The Detroit River served as a final stop on the Underground Railroad and was the most active entry point along the United States–Canada border for fugitive slaves. Escaping slaves often chose to cross through the Detroit River rather than flee to Mexico because of the river's location near free states made it less risky than traveling through slaveholding states that border Mexico. The strong Underground Railroad networks in

4140-415: The river. Inventory documents record a total of 17 cannons and 14 have been accounted for. It is believed that the British dragged the cannons onto the frozen river so they would sink with the spring thaw, and be kept from use by the American enemy. Another seven, larger cannons may have fallen off a barge closer to Amherstburg , Ontario , and may yet be found in the river. Much of the land that surrounds

The Detroit River, Lake St. Clair , and the St. Clair River are estimated to have carried 75% of all liquor smuggled into the United States during Prohibition. Government officials were unable or unwilling to deter the flow. The rum-running industry died when prohibition was repealed in 1933 by the Twenty-first Amendment . Because of

4347-466: The two countries do not share a land border along the river. Grosse Ile is the largest and most populated of all islands, and Fighting Island is the largest Canadian island. Most islands are located in the southern portion of the river. Europeans first recorded navigating the Detroit River in the 17th century. The Iroquois traded furs with the Dutch colonists at New Amsterdam by traveling through

From 1920 to 1933, the United States (US) enforced the Prohibition era . The sale, manufacture, and transportation of alcohol for consumption were nationally banned. Detroit, as the largest city bordering Canada, where alcohol remained legal during Prohibition, became

4554-576: Was controlled by the British Empire and remained neutral in the war. The Union feared the CSA would cross the Detroit River to launch this attack. For that reason, Union forces regularly patrolled the Detroit River and the fortification at Fort Wayne improved, although it was far removed from any major combat. A Confederate plot to capture the U.S. Navy warship, USS Michigan , and liberate Confederate prisoners from Johnson Island , in western Lake Erie,

4623-684: Was known literally as the "River of the Strait". When Great Britain defeated the French in the Seven Years' War (known as the French and Indian War on the American front), it took over control of the Detroit River, as well as other French territory east of the Mississippi River. The newly formed United States claimed this territory during the American Revolution , but the British did not transfer it until 1796. During

4692-608: Was narrowly averted only after the Confederates had captured two passenger steamships. At the beginning of the 20th century, Detroit's industrialization took off on an unprecedented scale. The Detroit River became the world's busiest commercial river and in 1908 was dubbed "the Greatest Commercial Artery on Earth" by The Detroit News . In 1907, the Detroit River carried 67,292,504 tons (61 billion kg) of shipping commerce through Detroit to markets all over

4761-640: Was recovered during a July 1992 project, and the anchor was installed in the yard of the Dossin Great Lakes Museum on Belle Isle . Since the 1980s, divers have recovered a total of six 1700s-era cannons from the river. The last was found in 2011 near the Cobo Center . They are believed to have been part of the pre- War of 1812 inventory kept by the British garrison in this area. Historians believe another three cannon may still be in
