Belmont Lake is a 117-acre body of water within Barkcamp State Park in eastern Ohio. The lake, created in 1963 by damming Barkcamp Creek, is surrounded by mature woodlands and sandstone hills characteristic of the Appalachian Plateau.

Only electric motors and hand-powered vessels are permitted on the lake. A public boat launch ramp provides access, and seasonal boat tie-ups are available. The park has a kayak rental facility on site. Swimming from boats is explicitly prohibited.

The shoreline features a 700-foot beach on the east side of the lake, and multiple picnic areas around the water's edge provide tables, grills, and basic facilities. The surrounding landscape consists of second-growth forest representative of Ohio's original woodland coverage, offering paddlers views of native flora and opportunities to spot white-tailed deer, wild turkey, and various songbirds.

Anglers sharing the water with paddlers can expect to find bass, bluegill, catfish, crappie, saugeye, and trout. The lake's relatively small size makes it ideal for peaceful paddling excursions without significant powerboat traffic.

The park's name derives from its history as a logging camp where trees were stripped of their bark before milling. The surrounding area holds historical significance as early Ohio settlement territory, where conflicts between Native Americans and settlers occurred prior to the 1795 Treaty of Greenville.

Winter activities on the lake include ice fishing and ice skating when conditions permit, suggesting seasonal closure of paddling opportunities during cold months.
