The MWCD was created in 1933 and is the largest conservancy district in Ohio, serving more than 2 million residents in an 18-county area. It manages 54,000 acres for public use, comprised of 16,000 acres of water surface at 10 lakes and 38,000 acres of land.
The Walhonding and Tuscarawas rivers meet in Coshocton in Coshocton County to form the Muskingum River, which flows south to the Ohio River at Marietta in Washington County.MWCD is the largest watershed in Ohio, covering one-fifth of the state of Ohio and provides flood reduction and water conservation benefits through a system of dams and reservoirs. Through a partnership with the U.S. Army Corps of Engineers (USACE), which owns and operates the dams in the region, the system of reservoirs and dams has prevented more than $7 billion in potential property damage and saved countless lives.
