The Delaware Lake dam was constructed by the U.S. Army Corps of Engineers for flood control before being converted to state park management.
The park's location is a significant site for fossil hunting in limestone formations exposed along the reservoir shoreline.
Delaware Lake is periodically stocked by the Ohio Division of Wildlife to support a robust saugeye population.
The park contains a specific wildlife area that is managed to attract migratory waterfowl during spring and autumn.
The park landscape is a remnant of the glacial till plains that characterize much of central Ohio's topography.
Delaware State Park is a 1,300-acre recreational facility centered on the 1,300-acre Delaware Lake reservoir in central Ohio. The park features a sandy public swimming beach and a designated dog park area. It offers over 140 campsites equipped with electric hookups and shared shower facilities. Visitors have access to multiple boat launch ramps for motorized and non-motorized watercraft. The park land encompasses diverse habitats including open meadows and secondary-growth woodlands. Hiking trails wind through the forested sections, providing opportunities for local wildlife observation. It serves as a regional hub for fishing, specifically for saugeye, crappie, and bass. The facility is managed by the Ohio Department of Natural Resources.

Check the ODNR water quality advisories online before planning a swimming excursion, as algae blooms can impact the reservoir during late summer.
Pack insect repellent, as the proximity to the reservoir leads to significant mosquito activity during humid summer evenings.
If planning to camp, reserve sites well in advance via the Ohio State Parks reservation portal, as sites fill up months ahead during peak season.
Attempting to swim outside of the designated beach area, as the reservoir bottom can be silty and contain submerged stumps.
Campgrounds operate on a seasonal basis; some amenities are unavailable during winter months.
Leash dogs at all times unless within the designated dog park; pack out all trash to keep wildlife areas clean.
