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.
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 ...
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 .
Pentwater Lake is a water body adjacent to the village of Pentwater, Michigan. Its primary inlet is the Pentwater River ; its outlet is a man-made channel flowing into Lake Michigan . Pentwater Lake has a surface area of 431 acres (174 ha), a maximum depth of 50 feet (15 m), and an average depth of 27 feet (8.2 m).
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 ...
Last summer, Lake Michigan was 10 degrees above normal, which resulted in the water taking longer to cool down in the winter. At the start of the year, only 3% of the Great Lakes were covered in ice.
The Illinois and Michigan Canal (I&M) opened in 1848. In 1900, the Chicago Sanitary and Ship Canal replaced the I&M and reversed the flow of the Chicago River so it no longer flowed into Lake Michigan. The United States Army Corps of Engineers maintains a 9-foot-deep (2.7 m) navigation channel in the waterway. [1]
