History & Natural Features


East Fork State Park is home to the Little Miami River Basin, which possesses evidence of human activity dating back nearly 3,000 years ago. The Moundbuilders, specifically the Adena and Hopewell nations, occupied this area. The mound near Elklick Road is thought to have been built by the Adena. The Erie also lived here much later, though by 1655 this group had been completely wiped out by the powerful Iroquois. The area was virtually uninhabited through the remainder of the 17th century.

By the early 1800s, European Americans had begun to occupy the new state of Ohio. The new settlers were attracted to the East Fork region and began early commercial activities such as grist mills, sawmills, blacksmith shops, tanneries, and stagecoach depots.

In 1869, two gold mines operated in the vicinity. One mine was located near Elklick and consisted of a flume for washing gravel containing flakes of gold. The mine near Twin Bridges tunneled underground to reach gold deposits encased in bedrock.

Not far from the park office is the site where Reverend John Collins built a log church around 1807. Although the structure no longer stands, some of the hand-hewn timbers, secured with wooden pegs and hand-forged nails, were used to construct the existing building, “Old Bethel Church” on Elklick Road.

In the late 20the century, the area took on a new appearance due to the creation of the East Fork Reservoir in 1978. As part of the U.S. Army Corps of Engineers flood control program, William H. Harsha Lake, and the surrounding region, comprise one of southwest Ohio’s largest recreational areas. ODNR currently leases East Fork State Park from the U.S. Army Corps of Engineers.

Natural Features

Located in Clermont County, East Fork State Park is characterized by a landscape shaped by the forces of the Illinoian and Wisconsinan glaciers. The region exhibits beautiful hill country scenery and is noted for the occurrence of remnant prairie habitats. Illinoian glacial deposits are not common in Ohio, but they can be observed at East Fork and the surrounding area.

East Fork's diverse landscape includes dry-forested hills, rocky cascades, abandoned farmlands, thickly grown floodplains, marshy grasslands, and swamp forests. This diversity lends well to an abundance of plant and animal life. Woodlands are composed of beech, sugar maple, red and white oak, shagbark hickory, and wild black cherry. The swamp forests contain silver maple, American elm, sycamore, and black gum. The meadows and remnant prairies contain big bluestem grass and purple coneflower among others.

Animals of the area include eastern plains garter snake, fence lizard, red fox, deer, raccoon, Canada geese, song sparrow, eastern meadowlark, and the barn swallow.
