== History ==
{{Further|Lake Chicago|Lake Algonquin|Lake Chippewa|Nipissing Great Lakes}}

Some of the most well-studied early human inhabitants of the Lake Michigan region were the [[Hopewell tradition|Hopewell Native Americans]]. Their culture declined after 800 AD, when, for the following few hundred years, the region was the home of peoples known as the [[Woodland period|Late Woodland Native Americans]]. In the early 17th century, when Western European explorers made their first forays into the region, they encountered descendants of the Late Woodland Native Americans, mainly the historic [[Ojibwe]], [[Menominee]], [[Noquet]], [[Sauk people|Sauk]], [[Meskwaki]], [[Ho-Chunk]], [[Miami people|Miami]], [[Odawa]] and [[Potawatomi]] peoples. The [[French people|French]] explorer [[Jean Nicolet]] is believed to have been the first European to reach Lake Michigan, possibly in 1634 or 1638.<ref>{{harvnb|Bogue|1985|pp=7–13}}</ref> In the earliest European maps of the region, the name of '''Lake Illinois''' has been found (named for the [[Illinois Confederation]] of tribes),<ref>{{Cite web |title=1733d4 |url=http://www.libs.uga.edu/darchive/hargrett/maps/1733d4.jpg |url-status=dead |archive-url=https://web.archive.org/web/20210507211114/https://www.libs.uga.edu/darchive/hargrett/maps/1733d4.jpg |archive-date=May 7, 2021 |access-date=November 6, 2004}}</ref> in addition to that of "Michigan". During the 1640s and 1650s, the [[Beaver Wars]] (over the [[North American fur trade|fur trade]] with the European colonies), initiated by the [[Iroquois]], forced a massive demographic-shift, as their western neighbors fled the violence. The Iroquois sought refuge to the west and north of Lake Michigan.<ref>{{cite book |first=Richard |last=White |author-link=Richard White (historian) |title=The Middle Ground: Indians, Empires, and Republics in the Great Lakes Region, 1650–1815 |url={{google books|fHLfiOZVzmMC|plainurl=yes}} |series=Cambridge studies in North American Indian history |publisher=Cambridge University Press |date=2011 |orig-year=1991 |edition=Twentieth Anniversary |isbn=978-1-107-00562-4 }}</ref>

The Straits of Mackinac were an important Native American travel corridor and fur-trade route. Located on the southern side of the straits sits the town of [[Mackinaw City, Michigan]], the site of [[Fort Michilimackinac]] (a reconstructed French fort founded in 1715); on the northern side is [[St. Ignace, Michigan]], site of a French Catholic mission to the Indians (founded in 1671). In 1673, [[Jacques Marquette]], [[Louis Jolliet]], and their crew of five [[Métis]] [[voyageurs]] followed Lake Michigan to Green Bay and up the [[Fox River (Green Bay tributary)|Fox River]], [[Fox–Wisconsin Waterway|nearly to its headwaters]], in their search for the [[Mississippi River]]. By the late 18th century, the eastern portions of the straits were controlled by [[Fort Mackinac]] on [[Mackinac Island]], a [[Colonial history of the United States|British colonial]] and early [[United States Armed Forces|American military]] base and fur trade center, founded in 1781.<ref>{{cite web|title=Colonial Fort Michilimackinac|url=http://www.mightymac.org/michilimackinac.htm|website=Mighty Mac|access-date=July 6, 2014|archive-date=November 27, 2020|archive-url=https://web.archive.org/web/20201127013927/http://www.mightymac.org/michilimackinac.htm|url-status=live}}</ref>

With the advent of European exploration into the area in the late 17th century, Lake Michigan became used as part of a line of waterways leading from the [[Saint Lawrence River]] to the Mississippi River and thence to the [[Gulf of Mexico]].<ref>{{harvnb|Bogue|1985|pp=14–16}}</ref> French [[coureurs des bois]] and voyageurs established small ports and trading communities, such as Green Bay, on the lake during the late 17th and early 18th centuries.<ref>{{harvnb|Shelak|2003|p=3}}</ref> In the 19th century, Lake Michigan was integral to the development of [[Chicago]] and the [[Midwestern United States]] west of the lake. For example, 90% of the grain shipped from Chicago traveled by ships east over Lake Michigan during the [[Wiktionary: antebellum|antebellum]] years. The volume rarely fell below 50% after the [[American Civil War|Civil War]] even with the [[Rail transportation in the United States|major expansion of railroad shipping]].<ref>{{cite book|last=Cronon|first=William|title=Nature's Metropolis: Chicago and the Great West|year=1991|publisher=W.

The first person to reach the deep bottom of Lake Michigan was [[J. Val Klump]], a scientist at the [[University of Wisconsin–Milwaukee]] in 1985. Klump reached the bottom via [[submersible]] as part of a research expedition.<ref>{{cite journal|title=Variations in Sediment Accumulation Rates and the Flux of Labile Organic Matter in Eastern Lake Superior Basins |year=1989 |journal=[[The Journal of Great Lakes Research]] |bibcode=1989JGLR...15..104K |url=http://loracsevents.com/dev/iaglr/dev/jglr/db/view_contents.php?pub_id=965&mode=view&table=yes&topic_id=30&mode=topic_section&volume=15&issue=1 |archive-url=https://archive.today/20121203024023/http://loracsevents.com/dev/iaglr/dev/jglr/db/view_contents.php?pub_id=965&mode=view&table=yes&topic_id=30&mode=topic_section&volume=15&issue=1 |url-status=usurped |archive-date=December 3, 2012 |access-date=August 9, 2009 |last1=Klump |first1=J.

== Hydrology ==
{{Anchor|Geography}}

The [[Milwaukee Reef]], running under Lake Michigan from a point between Milwaukee and Racine to a point between Grand Haven and Muskegon, divides the lake into northern and southern basins. Each basin has a clockwise flow of water, deriving from rivers and winds. Prevailing westerly winds tend to move the surface water toward the east, producing a moderating effect on the climate of western Michigan. There is a mean difference in summer water temperatures of 5 to 10 degrees Fahrenheit (2 to 5 degrees Celsius) between the Wisconsin and Michigan shores.<ref name="hilton">{{harvnb|Hilton|2002|pp=3–5}}</ref>

Hydrologically Michigan and Huron are the same body of water (sometimes called [[Lake Michigan-Huron]]) but are normally considered distinct. Counted together, it is the largest body of fresh water in the world by surface area. The [[Mackinac Bridge]] is generally considered the dividing line between them. The main inflow to Lake Michigan from Lake Superior, through Lake Huron, is controlled by the locks operated by the bi-national [[International Joint Commission|Lake Superior Board of Control]].<ref>{{Cite news |last=Briscoe |first=Tony |date=July 13, 2018 |title=What happens when Lake Superior has too much water? |language=en-US |work=Chicago Tribune |url=http://www.chicagotribune.com/news/ct-met-lake-michigan-superior-water-levels-20180709-story.html |access-date=July 15, 2018 |archive-date=June 26, 2021 |archive-url=https://web.archive.org/web/20210626121817/https://www.chicagotribune.com/news/ct-met-lake-michigan-superior-water-levels-20180709-story.html |url-status=live }}</ref>

=== Connection to other water bodies ===
In the mid 20th century, construction of the [[Saint Lawrence Seaway]] and [[Great Lakes Waterway]] opened the Great Lakes to ocean-going vessels. But the wider ocean-going container ships that were developed later do not fit through the locks on these routes, which limits shipping on the lakes. [[Lake freighter]]s are used on the lakes that are too large to pass the locks and enter the ocean. Despite their vast size, large sections of the Great Lakes freeze in winter, interrupting most shipping. Some icebreakers ply the lakes.

Lake Michigan is connected by the [[Illinois Waterway]] to the [[Gulf of Mexico]] via the [[Illinois River]] and the Mississippi River. Commercial tug-and-barge traffic on these waterways is heavy. Pleasure boats can enter or exit the Great Lakes by way of the [[Erie Canal]] and Hudson River in New York. The Erie Canal connects to the Great Lakes at the east end of [[Lake Erie]] (at [[Buffalo, New York]]) and at the south side of [[Lake Ontario]] (at [[Oswego, New York]]).

=== Water level ===
The lake fluctuates from month to month with the highest lake levels typically occurring in summer. The normal high-water mark is {{convert|2.00|ft|m}} above datum (''{{convert|577.5|ft|m|abbr=on}}''). In October 1986, Lakes Michigan and Huron reached their highest level at {{convert|5.92|ft|m}} above datum.<ref name="COE-2009">Monthly bulletin of Lake Levels for The Great Lakes; September 2009; U.S. Army Corps of Engineers, Detroit District</ref> The monthly average high-water records were broken for several months in a row in 2020.<ref name="armymilGreatLakesData">{{Cite web|date=February 3, 2021|title=Great Lakes Water Level Data|url=https://www.lre.usace.army.mil/Missions/Great-Lakes-Information/Great-Lakes-Information-2/Water-Level-Data/|access-date=February 9, 2021|archive-date=May 27, 2021|archive-url=https://web.archive.org/web/20210527020105/https://www.lre.usace.army.mil/Missions/Great-Lakes-Information/Great-Lakes-Information-2/Water-Level-Data/|url-status=dead}}</ref>

===Drinking water===
[[File:Grand Traverse Bay from Elk Rapids.jpg|thumb|[[Grand Traverse Bay]], a large bay of Lake Michigan in Michigan's [[Lower Peninsula of Michigan|Lower Peninsula]], from the community of [[Elk Rapids, Michigan|Elk Rapids]]]]
Lake Michigan, like the other Great Lakes, supplies drinking water to millions of people in bordering areas.

The Great Lakes are collectively administered by the [[Conference of Great Lakes and St. Lawrence Governors and Premiers]], intergovernmental organization led by the governing chief executives of the Canadian provinces of [[Ontario]] and [[Québec]], and by the governors of the U.S. states of [[Illinois]], [[Indiana]], [[Michigan]], [[Minnesota]], [[New York (state)|New York]], [[Ohio]], [[Pennsylvania]], and [[Wisconsin]]. The Conference came into force, in December 2008, with the enactment of laws in all of the states and the two provinces, and the enactment of a United States federal law.

Environmental problems can still plague the lake. [[Steel mill]]s and refineries operate near the Indiana shoreline. The ''[[Chicago Tribune]]'' reported that [[BP]] is a major polluter, dumping thousands of pounds of raw [[sludge]] into the lake every day from its [[Whiting, Indiana]], oil refinery.<ref>{{cite news |last=Hawthorne |first=Michael |date=July 15, 2007 |title=BP gets break on dumping in lake |newspaper=Chicago Tribune |url=https://www.chicagotribune.com/chi-pollute_15jul15-story.html |access-date=October 14, 2020 |archive-date=June 22, 2021 |archive-url=https://web.archive.org/web/20210622010856/https://www.chicagotribune.com/chi-pollute_15jul15-story.html |url-status=live }}</ref> In March 2014 BP's Whiting refinery was responsible for spilling more than {{convert|1600|USgal|L}} of oil into the lake.<ref>{{cite news |last=Hawthorne |first=Michael |date=March 28, 2014 |title=BP raises estimate of Lake Michigan oil spill |newspaper=Chicago Tribune |url=https://www.chicagotribune.com/news/ct-xpm-2014-03-28-chi-bp-oil-spill-lake-michigan-20140327-story.html |access-date=October 14, 2020 |archive-date=November 17, 2020 |archive-url=https://web.archive.org/web/20201117003355/https://www.chicagotribune.com/news/ct-xpm-2014-03-28-chi-bp-oil-spill-lake-michigan-20140327-story.html |url-status=live }}</ref>

=== Beaches ===
[[File:Gfp-indiana-dunes-national-lakeshore-lake-michigan-lakeshore.jpg|thumb|View of Lake Michigan from [[Indiana Dunes National Park]]]]
Lake Michigan has many beaches. The region is often referred to as the "[[Third Coast]]"<ref>{{cite web |title=NOAA Great Lakes Region |url=http://www.regions.noaa.gov/great-lakes/index.php/regional-statistics/ |access-date=September 15, 2015 |publisher=[[NOAA]] |archive-date=April 21, 2021 |archive-url=https://web.archive.org/web/20210421111440/https://www.regions.noaa.gov/great-lakes/index.php/regional-statistics/ |url-status=live }}</ref> of the United States, after those of the [[Atlantic Ocean]] and the [[Pacific Ocean]]. The sand is often soft and off-white, known as "[[singing sand]]s" because of the squeaking noise (caused by high [[quartz]] content) it emits when walked upon. Some beaches have sand dunes covered in green [[Ammophila breviligulata|beach grass]] and [[Prunus pumila|sand cherries]], and the water is usually clear and cool, between {{convert|55|and|80|F|C}},<ref>{{cite web|title=Michigan Sea Grant Coastwatch|url=http://www.coastwatch.msu.edu/twomichigans.html |url-status=dead |archive-url=https://web.archive.org/web/20100212190032/http://coastwatch.msu.edu/twomichigans.html |archive-date=February 12, 2010 |access-date=January 14, 2010 |publisher=Coastwatch.msu.edu}}</ref> even in the late summer months. However, because prevailing westerly winds tend to move the surface water toward the east, there is a flow of warmer water to the Michigan shore in the summer.<ref name="hilton" />

The sand dunes located on the east shore of Lake Michigan are the largest freshwater dune system in the world. In multiple locations along the shoreline, the dunes rise several hundred feet above the lake surface. Large dune formations can be seen in many state parks, national forests and national parks along the Indiana and Michigan shoreline. Some of the most expansive and unique dune formations can be found at [[Indiana Dunes National Park]], [[Saugatuck Dunes State Park]], [[Warren Dunes State Park]], [[Hoffmaster State Park]], [[Silver Lake State Park (Michigan)|Silver Lake State Park]], [[Ludington State Park]], and [[Sleeping Bear Dunes National Lakeshore]]. Small dune formations can be found on the western shore of Lake Michigan at [[Illinois Beach State Park]], and moderate-sized dune formations can be found in [[Kohler-Andrae State Park]] and [[Point Beach State Forest]] in Wisconsin. A large dune formation can be found in [[Whitefish Dunes State Park]] in Wisconsin in the [[Door Peninsula]]. Lake Michigan beaches in [[Northern Michigan]] are the only place in the world, aside from a few inland lakes in that region, where [[Petoskey stone]]s, the Michigan state stone, can be found.<ref>Wolgamott, K. (May 17, 2018). "Where to Find Petoskey Stones in Michigan." Retrieved from https://www.michigan.org/article/trip-idea/where-find-petoskey-stones-michigan {{Webarchive|url=https://web.archive.org/web/20210624222145/https://www.michigan.org/article/trip-idea/where-find-petoskey-stones-michigan |date=June 24, 2021 }}</ref>

The beaches of the western coast and the northernmost part of the east coast are often rocky, with some sandy beaches. The southern and eastern beaches are typically sandy and dune-covered. This is partly because of the prevailing winds from the west (which also cause thick layers of ice to build on the eastern shore in winter). The Chicago city waterfront has been developed for parks, [[List of beaches in Chicago|beaches]], harbors and marinas, and residential developments connected by the [[Chicago Lakefront Trail]]. Where there are no beaches or marinas, stone or concrete revetments protect the shoreline from erosion. The Chicago lakefront is accessible for about {{convert|24|mi|km}} between the city's southern and northern limits along the lake.

=== Cities ===
[[File:Lake Michigan Watershed.png|thumb|Lake Michigan basin]]
Twelve million people live along Lake Michigan's shores, mainly in the [[Chicago]] and [[Milwaukee]] metropolitan areas. The economy of many communities in [[northern Michigan]] and [[Door County, Wisconsin]], is supported by [[tourism]], with large seasonal populations attracted by Lake Michigan.<ref>{{Cite web |url=http://www.miseagrant.umich.edu/explore/coastal-communities/economic-vitality-and-the-great-lakes/ |title=Economic Vitality and the Great Lakes &#124; Michigan Sea Grant |access-date=February 3, 2018 |archive-url=https://web.archive.org/web/20171219144458/http://www.miseagrant.umich.edu/explore/coastal-communities/economic-vitality-and-the-great-lakes/ |archive-date=December 19, 2017 |url-status=dead }}</ref> Many seasonal residents have summer homes along the waterfront and return to other homes for the winter.

=== Fishing ===
[[File:Milwaukee Public Museum Group, Lake Fisheries (NBY 23833).jpg|thumb|Lake fisheries postcard produced for the Milwaukee Public Museum, the backside identifies the fishermen as using a pound net.]]Lake Michigan is home to a small variety of fish species and other organisms. It was originally home to [[lake whitefish]], [[lake trout]], [[yellow perch]], [[panfish]], [[largemouth bass]], [[smallmouth bass]] and [[bowfin]], as well as some species of [[catfish]]. As a result of improvements to the [[Welland Canal]] in 1918, an invasion of [[sea lamprey]]s and [[Overfishing|overharvesting]], there has been a decline in native lake trout populations, ultimately causing an increase in the population of another invasive species, the [[alewife (fish)|alewife]]. As a result, salmonids, including various strains of [[brown trout]], steelhead ([[rainbow trout]]), [[coho salmon|coho]] and [[chinook salmon]], were introduced as predators in order to decrease the wildlife population. This program was so successful that the introduced population of trout and salmon exploded, resulting in the creation of a large sport fishery for these introduced species. Lake Michigan is now stocked annually with steelhead, brown trout, and coho and chinook salmon, which have also begun natural reproduction in some Lake Michigan tributaries. However, several introduced invasive species, such as lampreys, [[round goby]], [[zebra mussel]]s and [[quagga mussel]]s, continue to cause major changes in [[water clarity]] and fertility, resulting in knock-on changes to Lake Michigan's ecosystem, threatening the vitality of native fish populations.

Fisheries in inland waters of the United States are small compared to marine fisheries. The largest fisheries are the landings from the Great Lakes, worth about $14&nbsp;million in 2001.<ref name="NMFS 2001">[[NOAA]]/[[NMFS]]: (2001) [http://www.st.nmfs.gov/st1/fus/fus03/index.html Fisheries of the United States, 2003] {{webarchive|url=https://web.archive.org/web/20070810195334/http://www.st.nmfs.gov/st1/fus/fus03/index.html |date=August 10, 2007 }}</ref> Michigan's commercial fishery today consists mainly of 150 tribe-licensed commercial fishing operations through the Chippewa-Ottawa Resource Authority and tribes belonging to the Great Lakes Indian Fish and Wildlife Commission, which harvest 50 percent of the Great Lakes commercial catch in Michigan waters, and 45 state-licensed commercial fishing enterprises.<ref name=miseagrant7jan2013>{{cite report |url=http://www.miseagrant.umich.edu/files/2013/01/07-701-fs-whitefish-marketing.pdf |title=Michigan Commercial Fisheries Marketing and Product Development |publisher=University of Michigan Sea Grant |location=Ann Arbor, Michigan |access-date=April 30, 2013 |archive-url=https://web.archive.org/web/20130412020407/http://www.miseagrant.umich.edu/files/2013/01/07-701-fs-whitefish-marketing.pdf |archive-date=April 12, 2013 |url-status=dead }}</ref> The prime commercial species is the lake whitefish. The annual harvest declined from an average of {{convert|11|e6lb|kg}} from 1981 through to 1999 to more recent annual harvests of {{convert|8|to|9.5|e6lb|kg}}. The price for lake whitefish dropped from $1.04/lb. to as low as $0.40/lb during periods of high production.<ref name=miseagrant7jan2013 />

Sports fishing includes salmon, whitefish, [[smelt (fish)|smelt]], lake trout and [[walleye]] as major catches. In the late 1960s, successful stocking programs for Pacific salmon led to the development of Lake Michigan's charter fishing industry.<ref name=miseagrant2009>{{cite report |url=http://www.miseagrant.umich.edu/downloads/fisheries/economy/Michigan-Charter-Fishing-Fact-Sheet.pdf |first=Dan |last=O'Keefe |year=2009 |title=Charter Fishing in Michigan: A Profile of Customers and Economic Impacts |publisher=University of Michigan Sea Grant |location=Ann Arbor, Michigan |access-date=April 30, 2013 |archive-date=May 13, 2017 |archive-url=https://web.archive.org/web/20170513222024/http://www.miseagrant.umich.edu/downloads/fisheries/economy/Michigan-Charter-Fishing-Fact-Sheet.pdf |url-status=live }}</ref>

=== Shipping ===
Like all of the Great Lakes, Lake Michigan is today used as a major [[mode of transport]] for bulk goods. In 2002, 162&nbsp;million net [[ton]]s of dry bulk cargo were moved via the Lakes. This was, in order of volume: iron ore, grain and [[potash]].<ref>{{Cite report|url=http://www.portdetroit.com/wp-content/uploads/2015/02/Great-Lakes-Shipping-Study-Final.pdf|title=Great Lakes Shipping Study|publisher=U.S. Department of Homeland Security|date=January 13, 2014|access-date=May 30, 2018|archive-date=November 11, 2020|archive-url=https://web.archive.org/web/20201111204840/http://www.portdetroit.com/wp-content/uploads/2015/02/Great-Lakes-Shipping-Study-Final.pdf|url-status=dead}}</ref> The iron ore and much of the stone and coal are used in the steel industry. There is also some shipping of liquid and containerized cargo, but most container vessels cannot pass the locks on the [[Saint Lawrence Seaway]] because the ships are too wide. The total amount of shipping on the lakes has been on a downward trend for several years. The [[Port of Chicago]], operated by the [[Illinois International Port District]], has grain (14&nbsp;million bushels) and bulk liquid (800,000 barrels) storage facilities along [[Lake Calumet]]. The central element of the Port District, [[Calumet Harbor]], is maintained by the [[U.S. Army Corps of Engineers]].<ref>U.S. Army Corps of Engineers (November 2007).

=== Ferries ===
[[File:SS Badger CloseUP.png|alt=The SS Badger departing Manitowoc for Ludington|thumb|SS ''Badger'' operates ferry services between Manitowoc and Ludington]]
Two passenger and vehicle ferries operate ferry services across Lake Michigan, both connecting Wisconsin on the western shore with Michigan on the east. From May to October, the historic steamship, {{SS|Badger}}, operates daily between Manitowoc, Wisconsin, and Ludington, Michigan,<ref>{{Cite web |title=Schedule and Fares |url=http://www.ssbadger.com/schedule-fares/ |access-date=April 1, 2018 |publisher=SS Badger |archive-date=May 7, 2021 |archive-url=https://web.archive.org/web/20210507040819/https://www.ssbadger.com/schedule-fares/ |url-status=live }}</ref> connecting [[U.S. Route 10|U.S. Highway 10]] between the two cities. The ''[[Lake Express]]'', established in 2004, carries passengers and vehicles across the lake between Milwaukee, Wisconsin, and Muskegon, Michigan.

=== Tourism and recreation ===
Tourism and recreation are major industries on all of the Great Lakes. A few small cruise ships operate on Lake Michigan, including a couple of sailing ships. Many other water sports are practiced on the lakes, such as yachting, sea kayaking, diving, kitesurfing and lake surfing. [[Great Lakes passenger steamers]] have been operating since the mid-19th century. Several ferries currently operate on the Great Lakes to carry passengers to various islands, including [[Beaver Island (Lake Michigan)|Beaver Island]] and [[Bois Blanc Island (Michigan)]]. Currently, two car ferry services traverse Lake Michigan from around April to November: the SS Badger, a steamer from Ludington, Michigan, to Manitowoc, Wisconsin, and the [[Lake Express]], a high speed catamaran from Milwaukee to Muskegon, Michigan.
