Its stone core and soil foundation contribute to its structural integrity, while the dam's 569-foot length and 8-acre surface area provide ample protection for the surrounding area. Despite its low hazard potential, the dam is equipped with a 235 cubic feet per second maximum discharge capacity to manage excess water flow during heavy rainfall events.
