General Information

Charles Mill Dam is located on the Black Fork of the Mohican River, 10 miles east of Mansfield and 10 miles southwest of Ashland, Ohio. The lake is located in Ashland and Richland counties with the dam being located in Ashland County. Charles Mill Dam was constructed in 1935-36 and is primarily for flood control but also for recreation and fish and wildlife management.          

Charles Mill Dam is a rolled earth fill dam with an impervious, water resistant, clay core. The dam, is 48 feet high, 1,390 feet long and 20 feet wide. This flood reduction system also includes two dikes and one levee. These structures, the dam, dikes and levee, hold the water that may build up behind them from the 215 square mile drainage area the dam serves. The dam also has two spillways to handle water above the maximum the dam is designed to hold; one is built into the gate house, the other is beyond the gate house against the right abutment. There are five gates which allow the water to pass through the dam and provide control of it. During the summer months the lake is kept at about 31 feet at the dam which provides 1,350 surface acers of water.  At that level the water is backed up the Black Fork about 5.2 miles. When the dam is holding the maximum flood water it is designed to hold there would be 6,050 surface acres of water behind the dam and water would be backed up the Black Fork 19.8 miles.   

The Day Use Area below the dam is a peaceful, scenic place to picnic with grills, tables, (one is accessible), rest rooms and, in 2006, a new playground was installed.  The restrooms are open on a seasonal basis (May-September). There are open grassy areas for playing and the river nearby.  Fishing is a popular activity in this area. 

The Muskingum Watershed Conservancy District administers the recreation facilities on the lake behind the dam through their facilities at Charles Mill Lake Park. They host an annual classic car show in early Sept., for more information contact Charles Mill Lake Park Office at (419) 368-6885 or visit their web site at

Historical Info

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 Attacks."  An attack took place within a mile of the dam site following the removal of the Piqua Indians from their tribal home area. The Native Americans first attacked 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 South on 603 watch for the sign directing you to a historical monument erected to the memory of those settlers and soldiers who were killed. In 2006 a new fence was erected around the monument, a photo is included in the photo section on this site. Members of the Copus family have held an annual reunion in this picnic 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 nearby.
