The Clam Lake Canal (sometimes called the Cadillac Canal) is a man-made 0.33 mile (0.53 km) long canal between Lake Mitchell and Lake Cadillac in Cadillac, Michigan. It was made by George A. Mitchell, the founder of the city of Cadillac (as the Village of Clam Lake), in the 1870s. The main purpose of the man-made canal was to facilitate the movement of logs to sawmills. Mitchell was a businessman, merchant, railwayman, lumber baron, and real estate developer who needed lumber to build the village, and saw the potential for further sawmill development.
