Madison Lake State Park is a public recreation area located 4miles east of London in the Darby Plains region of Madison County, Ohio, United States. The state park includes 106acres Madison Lake and of surrounding land.
The lake was formed in 1947 when the Madison Lake Dam was built on Deer Creek. The site was handed over to the Ohio Department of Natural Resources for use as a state park in 1950.
The park offers a boat ramp, 300feet sand beach, changing booths and restrooms, picnic areas, and shelters. A mile-long hiking trial skirts the lake's southern shore. The lake's northern end is reserved for hunting migratory game birds. The park is a popular fishing location, with bass, bluegill, crappie, and channel catfish found in the lake.
