Caesar Creek State Park

8570 OH-73, Waynesville, OH

Waynesville, OH

A clear blue reservoir ringed by trails and a swimming beach, with an exposed spillway where anyone can pick fossils out of ancient sea-floor rock.

Caesar Creek is a clear, deep reservoir in southwestern Ohio, ringed by wooded trails and edged with a broad swimming beach, but its real fame lies in the rock below the dam. The spillway there slices through layers of stone laid down on an ancient sea floor, and it is one of the most productive and accessible fossil-collecting sites in the country, where visitors with a simple permit can pick up brachiopods, trilobites, and corals hundreds of millions of years old.

The reservoir was created in the 1970s when the Army Corps of Engineers dammed Caesar Creek for flood control, and the excavation that formed it and its emergency spillway laid bare the fossil-rich Ordovician bedrock. The result is a park that works as both an outdoor playground and an open-air geology lesson, with a pioneer village added for a taste of early Ohio history.

What Travelers Love

  • Hunting for real marine fossils in the exposed rock below the dam spillway
  • A large sandy swimming beach on a clear reservoir
  • Miles of trails for hiking, mountain biking, and horseback riding around the lake
  • The restored pioneer village that preserves early Ohio log cabins and buildings

Worth Knowing

  • Collecting fossils at the spillway requires a permit from the visitor center, and rules limit what you can take
  • The reservoir was built for flood control, so water levels change with the season and after storms
  • Wear sturdy shoes for the spillway; the rock is uneven, loose, and can be slick
  • Trails are shared by hikers, cyclists, and riders in places, so watch for horses and bikes

Learn about Caesar Creek State Park

A sea floor turned to stone

The fossils here date to the Ordovician period, roughly 450 million years ago, when the land that is now Ohio lay beneath a warm, shallow tropical sea south of the equator. The sea teemed with life, and as those creatures died their shells and skeletons settled into the mud of the sea floor, which slowly hardened into the limestone and shale you can crack open at the spillway today.

The most common finds are brachiopods, small clam-like shellfish, along with the fanned columns of crinoids, colonial corals, snails, and, prized above all, trilobites, the segmented armored creatures that crawled the ancient sea bottom. Because the layers were exposed by the dam's construction and continue to weather out, the spillway keeps yielding fresh fossils, and a permit and a few rules keep the collecting sustainable.

Building the reservoir

Caesar Creek State Park exists because of flood control. After destructive floods, the Army Corps of Engineers dammed the creek in the 1970s to hold back high water and protect the towns downstream along the Little Miami River. The dam created the reservoir, and the state built the surrounding park for recreation.

The name reaches back to local legend. Caesar Creek is said to be named for an enslaved man called Caesar who, according to tradition, was captured by the Shawnee, adopted into the tribe, and given the creek valley as his hunting ground. The story is part of the folklore of a valley that was Shawnee and Miami homeland before American settlement pushed those nations westward, and their descendant nations continue today, largely in Oklahoma.

The pioneer village and Quaker country

Within the park stands Caesar Creek Pioneer Village, a cluster of early Ohio log cabins, barns, and a covered bridge gathered and preserved to show how the first settlers lived. Several of the structures were moved here to save them, and volunteers keep the heritage crafts and traditions of the frontier era alive on the site.

The surrounding countryside was heavily settled by Quakers, who founded the nearby village of Waynesville and other communities and who opposed slavery, making this stretch of Ohio a corridor of the Underground Railroad. Waynesville today is famous for its antique shops and its autumn sauerkraut festival, a taste of the region's old agricultural and craft roots.

The lake, trails, and seasons

The reservoir is the summer heart of the park, with a large sandy beach, boating, and fishing for bass, crappie, and other species in the clear water. Trails circle the lake and thread the surrounding woods and prairie plantings, open to hikers, mountain bikers, and horseback riders, and the wetlands and fields draw deer, waterfowl, herons, and songbirds.

Spring and fall are prime for fossil hunting and hiking, with mild air and, in fall, color across the hardwood hills. Summer fills the beach and boat ramps, and winter empties the park to a quiet, stark beauty, though the exposed spillway can be cold and slick and water levels run low. Because the lake is drawn down for flood control, its edges shift through the seasons.
