Hargus Lake was created by the construction of a dam on Hargus Creek specifically to serve as a recreational water source.
The park is named after A.W. Marion, who served as the first director of the Ohio Department of Natural Resources.
The hiking trails feature varied elevation changes that showcase the transition between Ohio's glacial till plains and unglaciated Appalachian foothills.
The lake is frequently stocked with saugeye, largemouth bass, bluegill, and channel catfish.
A.W. Marion State Park is centered around the 146-acre Hargus Lake, a popular destination for anglers and non-motorized boaters. The park spans 319 acres of secondary forest and rolling terrain in Pickaway County. Visitors have access to roughly 7 miles of hiking trails that wind through wooded ravines and meadows. The park permits seasonal hunting in designated areas and provides public access to the lake via a boat launch. Facilities include multiple picnic shelters and a primitive campground. It serves as a regional hub for birdwatchers observing both waterfowl and migratory songbirds. The park is managed by the Ohio Department of Natural Resources.
