There is a Historical Marker in the Day Use Area that recounts the story's of "Frontier Violence During the War of 1812" and "English-Allied Indian Attack's ".  An attack took place within a mile of the dam site following the removal of the Piqua Indians from their tribal home area. The indians first attack the home of the Frederick Zimmer family, and their neighbor Martin Rufferner, killing everyone. Several days later four more pioneers were killed while defending the home of the James Copus family, including Rev. James Copus. As you drive S on 603 watch for the sign directing you to a historical monument erected to the memory of those settlers and soilders who were killed. In 2006 a new fence was erected around the momuent, a photo is included in the photo section on this site. Members of the Copus family have held an annual reunion in this picninc area for years. Tradition holds that Johnny Appleseed raced throughout the area warning others following the attacks.  In 2004 the Johnny Appleseed Heritage Center opened near by; the original production is no longer presented, check with the tourism number for their offerings.
