This depth compares with the maximum depths of 750 feet (229 m) in Lake Huron and 923 feet (281 m) in Lake Michigan. Although the Straits create a pronounced bottleneck in the contours of the shoreline and a major constriction in the local bathymetry , defining two distinct basins, they are still deep and wide enough to allow the free exchange ...
Lake Michigan (/ ˈ m ɪ ʃ ɪ ɡ ən / ⓘ MISH-ig-ən) is one of the five Great Lakes of North America.It is the second-largest of the Great Lakes by volume [5] (1,180 cu mi; 4,900 km 3) and depth (923 ft; 281 m) after Lake Superior and the third-largest by surface area (22,405 sq mi; 58,030 km 2), after Lake Superior and Lake Huron.
The main strait is 3 + 1 ⁄ 2 miles (5.6 kilometers) wide with a maximum depth of 295 feet (90 meters; 49 fathoms), [2] and connects the Great Lakes of Lake Michigan and Lake Huron. Given the large size and configuration of the straits, hydrologically, the two connected lakes are one body of water, studied as Lake Michigan–Huron.
The shipping channels pass on opposite sides of Neebish Island in the St Marys River. The waterway allows passage from the Atlantic Ocean to the inland port of Duluth on Lake Superior, a distance of 2,340 miles (3,770 km) and to Chicago, on Lake Michigan, at 2,250 miles (3,620 km). [3]
The Great Lakes Basin consists of the Great Lakes and the surrounding lands of the states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin in the United States, and the province of Ontario in Canada, whose direct surface runoff and watersheds form a large drainage basin that feeds into the lakes.

In 2022, researchers with the National Oceanic and Atmospheric Administration surveyed Lake Michigan with sonar inside the Wisconsin Shipwreck Coast National Marine Sanctuary, an area known as the ...
Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward.
