Hamilton County State Fish and Wildlife Area, also known as Dolan Lake, is located about 8 miles southeast of McLeansboro off Route 14.

Dolan Lake is the main attraction of the park. The earthen dam was constructed in 1962 and the lake was filled shortly thereafter. The 75-acre lake has 3 miles of shoreline and a maximum depth of 18 feet. The lake contains largemouth bass, bluegill, sunfish, crappie, channel catfish and bullheads. A launching ramp is available. Motors are limited to 10 HP.
