The Ohio River Basin Comprehensive Reconnaissance Study is a collaborative effort between 4 Corps Districts that share the Ohio River Basin – Huntington, Nashville, Louisville and Pittsburgh, the 15 basin states and a multitude of stakeholders, project sponsors and the public. This ongoing comprehensive reconnaissance-level basin plan will feature a preliminary reinvestment plan for the existing reservoirs and local protection projects as well as identifying opportunities for additional municipal and industrial water supply, hydropower facilities and restoration of damaged ecosystems. The Reconnaissance Study will provide a pathway for resolving not only the problems faced by Corps projects but also other Federal, regional, state and local water resources problems and needs while identifying opportunities for expanded and enhanced water management through future collaborative watershed planning and decision-making.
