benchLocated in Lake Mills on Rock Lake, Korth Lane E of County Highway S. Korth Park was purchased in 2000 to protect the water quality and fish habitat of Rock Lake. A packed limestone bicycle trail along the shore of Rock Lake connects Cedar Lane to Elm Point Road. A connecting trail to the Glacial Drumlin Trail, just to the south, was completed in 2003 on land purchased by the WIDNR. This trail connection creates a loop path around Rock Lake.
