 The names of the two lakes were changed in 1903, with Little Clam Lake renamed as Lake Cadillac (for the renamed community) and Big Clam Lake as Lake Mitchell, in honor of William W. Mitchell, the nephew and business partner of George A. Mitchell.Following the passing of the lumber era the lake became a regional tourist destination.William Mitchell State Park, popular with campers, now occupies the west shore of the lake, adjacent to the canal.
