Lake St. Clair, part of the Great Lakes system, borders which state?

Lake St. Clair is situated in the Great Lakes region and is directly connected to Lake Huron to the north and the Detroit River, which flows south into Lake Erie. This makes it a crucial part of the Great Lakes system. The lake is bordered primarily by the state of Michigan.

Michigan's proximity to Lake St. Clair includes significant urban areas such as the city of Detroit, which lies just west of the lake. The lake itself serves as a natural boundary between the state of Michigan and Ontario, Canada, further emphasizing its geographical importance.

In contrast, the other states listed—Montana, Ohio, and Wisconsin—are not adjacent to Lake St. Clair. Montana is located far to the west and is not part of the Great Lakes region. Ohio is situated to the south of Lake Erie and does not border Lake St. Clair directly. Wisconsin, while it borders other Great Lakes, is also not near Lake St. Clair. Hence, Michigan is indeed the correct answer regarding which state borders Lake St. Clair.
