This private dam, designed by Pharr Engineering, is an earth dam with a buttress core type, standing at 34 feet in height with a hydraulic height of 25 feet. The dam has a storage capacity of 63 acre-feet and a normal storage of 24 acre-feet, serving a drainage area of 89 square miles.
Despite being state-regulated and inspected, the dam is classified with a low hazard potential and a moderate risk assessment. With an uncontrolled spillway and outlet gates, the dam's condition remains unrated as of the last inspection in October 2016. Even though the dam meets guidelines and has not experienced any emergency situations, water resource and climate enthusiasts may find interest in the risk management measures and potential enhancements that could further ensure the safety and efficiency of Brook Hollow Lake Dam for the surrounding community and environment.
