Alum Creek Lake is located in Delaware County, Ohio, north of Columbus between I-71 and US 23.
Alum Creek flows south joining Big Walnut Creek, near Groveport in southeast Columbus, which joins the Scioto River. Alum Creek Lake was built by the U.S. Army Corps of Engineers to reduce the flood hazard along Alum and Big Walnut Creeks, the Scioto River, and along the Ohio River.
The city of Columbus shared part of the additional project cost for water supply for the metropolitan area. Other benefits of the lake project are recreation, fish and wildlife management, and downstream water quality. The majority of the park is leased to the Ohio Department of Natural Resources to operate as a State Park. The Corps of Engineers manages and operates the Visitor Center and the Below Dam Recreation Area, as well as the dam. Restrooms are located at the Visitor Center, the State Park Beach, the Lewis Center Picnic Area, Hollenback Rd. Boat Ramp and State Park Marina, State Park Campground, Horsemen’s Day Use Area/Camp, Kilbourne Fishing Access, Howard Rd. Boat Ramp, Cheshire Boat Ramp and Picnic Area, New Galena Boat Ramp, Cheshire Fishing Access, and the Below Dam Recreation Area.
