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 ...
Topographic maps display elevation above ground and are complementary to bathymetric charts. Bathymeric 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 ...
Depths which have been measured are indicated by the numbers shown on the chart. Depths on charts published in most parts of the world use metres. Older charts, as well as those published by the United States government, may use feet or fathoms. Depth contour lines show the shape of underwater relief. Coloured areas of the sea emphasise shallow ...
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
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.
Crystal Lake, the largest lake of this name in Michigan, is located near Lake Michigan in Benzie County about 25 miles (40 km) southwest of Traverse City and about 2 miles (3.2 km) northeast of Frankfort at . It measures approximately 2.5 by 8 miles (4.0 by 12.9 km), and has a maximum depth of 165 feet (50 m).
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). The lake contains 11,590 acre-feet (14,300,000 m 3), a volume of water that would cover 18 square miles (47 km ...
