Home                     Diamond Lake, Cassopolis, Michigan

Diamond Lake is located in southwest lower Michigan, in nearly the center of Cass County. It is situated southeast of the village, and county seat, Cassopolis. Four different townships intersect in its waters; Calvin, Jefferson, LaGrange, and Penn. The lake is 1,078 acres in size, 60% of the lake is less than 10 feet deep, and is 64 feet at its deepest. Most of its shoreline is lined with over 900 homes and cottages, including an occupied island of about 43 acres in the center of the lake, accessible to island residents by the privately owned ferry during the summer months. There is one marina on its shores, and one public boat launch. Click on for map and driving directions.
