Rock Lake is a 1365-acre lake located in south central Wisconsin, at Lake Mills, Jefferson County, Wisconsin about 20 miles from Madison. The lake’s maximum depth is 87 feet and is fairly clear. The lake is shaped as figure eight, with several distinct areas - Bean Lake State natural area, a protected marsh, the area often covered in tall aquatic vegetation that spreads out of the water and a sandy area where boats can anchor and swimming is possible. Visitors have access to the lake from several public boat landings and public beaches. The fishermen come to the lake for panfish, largemouth bass, smallmouth bass, northern pike and walleye. The Glacial Drumlin State Trail runs across an old rail road bridge across the southern portion of the lake.
