Lake Huron is one of the five Great Lakes of North America. It is shared on the north and east by the Canadian province of Ontario and on the south and west by the U.S. state of Michigan. The name of the lake is derived from early French explorers who named it for the indigenous people they knew as Huron (Wyandot) inhabiting the region. Hydrologically, Lake Huron comprises the eastern portion of Lake Michigan–Huron, having the same surface elevation as Lake Michigan, to which it is connected by the 5-mile-wide (8.0 km), 20-fathom-deep Straits of Mackinac. Combined, Lake Michigan–Huron is the largest freshwater lake by area in the world. The Huronian glaciation was named from evidence collected from Lake Huron region. The northern parts of the lake include the North Channel and Georgian Bay. Saginaw Bay is located in the southwest corner of the lake. The main inlet is the St. Marys River, and the main outlet is through the St. Clair River to Lake Erie. Lake Huron has a fairly large drainage basin covering parts of Michigan and Ontario. Water flows through Lake Huron faster than the other Great Lakes with a retention time of only 22 years.

Michigan is a state in the Great Lakes region of the Upper Midwest region of the United States. It borders Wisconsin to the northwest in the Upper Peninsula, and Indiana and Ohio to the south in the Lower Peninsula; it is also connected by Lakes Superior, Michigan, Huron, and Erie to Minnesota and Illinois, and the Canadian province of Ontario. With a population of nearly 10.12 million and an area of 96,716 sq mi (250,490 km2), Michigan is the 10th-largest state by population, the 11th-largest by area, and the largest by area east of the Mississippi River. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies. The name derives from a gallicized variant of the original Ojibwe word ᒥᓯᑲᒥ, meaning "large water" or "large lake".
