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.
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 ...
Topographic maps display elevation above ground and are complementary to bathymetric charts. 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 ...

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.
North of the peninsula, warm water from Green Bay flows into Lake Michigan on the surface, while at the same time, cold lakewater enters Green Bay deep underneath. [12] In a study looking at fish stomach contents, walleye were found to eat between 5-6% and lake whitefish and yellow perch over the course of a year. However, south of Chambers ...
Due to environmental contamination, a portion of the river was designated a Great Lakes Area of Concern (AOC) under the Great Lakes Water Quality Agreement of 1987. The designated site includes the lowermost 1.7-mile (2.7 km) portion of the Manistique River downstream of a dam in the city of Manistique, as well as the Manistique harbor at the mouth of the river on Lake Michigan.
