Lake Michigan

About

Lake Michigan is the third-largest of the Great Lakes and the only one entirely within the United States. It spans 307 miles long and 118 miles wide, with a surface area of 22,404 square miles. The lake is connected to Lake Huron via the Straits of Mackinac, maintaining water level equilibrium between them. Its maximum depth is 923 feet, found in the Chippewa Basin. Lake Michigan supports diverse marine life, including native species like lake trout and introduced species such as coho salmon. The lake's ecosystem is rich, hosting boreal forests and coastal fens in the north and dry sand prairies in the south. It provides habitat for numerous species and supports significant fishing industries. Economically, Lake Michigan is crucial for regional commerce, handling large quantities of iron ore, coal, and limestone. Its shoreline offers extensive recreational opportunities, including beaches and marinas, contributing to a thriving tourism industry. However, it faces challenges like pollution and invasive species, necessitating conservation efforts to protect its ecological balance.
