The dam stands at 25 feet in height and spans 1600 feet in length, providing a storage capacity of 2200 acre-feet and a maximum discharge of 6960 cubic feet per second. Its controlled spillway and slide gate outlet ensure efficient water management in times of high flow.
Despite being assessed as in fair condition during its last inspection in October 2011, SCS-Bear Hybarger Site-3 carries a significant hazard potential and a very high risk rating. The dam's condition assessment, emergency action plan, and risk management measures are areas that may require attention to enhance its resilience and safety. With a drainage area of 3.8 square miles, this dam plays a crucial role in mitigating flood events in the region and underscores the importance of proactive monitoring and maintenance to protect downstream communities and water resources.
