What is the largest lake entirely within the United States? Lake Michigan is the largest lake wholly within the United States by surface area.

Lake Michigan is one of North America’s five Great Lakes and has a surface area of about 22,400 square miles, or 58,000 square kilometres. It is bordered by Illinois, Indiana, Michigan, and Wisconsin, making it the only Great Lake located entirely inside one country. Major shoreline cities include Chicago, Milwaukee, and Green Bay.

Lake Michigan is about 307 miles long and reaches a maximum depth of roughly 923 feet. It connects to Lake Huron through the Straits of Mackinac. Because the two lakes have the same water level and are connected by a deep channel, scientists sometimes discuss them as one hydrological system, Lake Michigan–Huron.

The common trap is Lake Superior, which is larger overall but shared by the United States and Canada. Lake Huron is also larger than Michigan by surface area and crosses the international border. Lake Michigan therefore wins the specific “entirely within the United States” category, not the overall Great Lakes contest.
