Built in 1965, this earth dam stands at a height of 64 feet and stretches 445 feet in length, with a maximum storage capacity of 734 acre-feet. The dam's spillway, of uncontrolled type, boasts a width of 145 feet to handle a maximum discharge of 14,168 cubic feet per second.
Despite its critical role in flood control, the dam's condition assessment in April 2021 deemed it unsatisfactory, with a high hazard potential. The structure was last inspected in August 2021, with a recommended inspection frequency of once a year. The dam underwent structural modifications in 1996, and its emergency action plan (EAP) status is currently unknown. With a moderate risk assessment rating, the Greenbrier State Park Dam & Dike presents a complex management challenge that requires ongoing monitoring and maintenance to ensure public safety and infrastructure resilience in the face of changing climate patterns.
