The U.S. Army Corps of Engineers hereby informs the public of the initiation process to update the Regional Master Plan for six of the locks and dams located on the Ohio River. USACE defines a Master Plan as the strategic land use document that guides the comprehensive management and development of all recreational, natural, and cultural resources throughout the life of the water resource development projects. The master plans are a vital tool produced and used by USACE to guide the responsible stewardship of USACE-administered lands and resources for the benefit of present and future generations. Master Plans do not address the specifics of regional water quality, shoreline management or water level management, nor do they include changes to operation and maintenance of project operation facilities, navigation, or hydropower functions.
