Tappan Lake was created by impounding the waters of Little Stillwater Creek. Today, the lake covers 2,350 acres running from east to west. The dam is at the western edge of the lake. The Tappan Lake tailwaters are the remnants of the Little Stillwater Creek. Access to the area is provided by U.S. Route 250-36 and county Road T-280, which cross over the dam. There is a parking area at the dam. The land surrounding the lake, dam and tailwaters is owned by the Muskingum Watershed Conservancy District and is open to the public. Downstream there are signs alerting anglers to public-private property borders. Tappan Lakes tailwater cats will be found holding in the deeper pools in summer. Anglers should target pools ranging from 8 to 12 feet deep. Expect mostly flatheads with an occasional channel cat.
