With a hydraulic height of 12 feet and a structural height of 19 feet, this dam stands at 15 feet tall and stretches 234 feet in length. The pond has a normal storage capacity of 43 acre-feet and a maximum storage capacity of 68 acre-feet, covering a surface area of 13 acres and draining an area of 40 acres.
Despite its historical significance, Allendale Pond is currently assessed as being in poor condition with a low hazard potential. The last inspection in May 2018 revealed the need for improvements, and the dam is not under any state permitting or enforcement regulations. While the pond does have an emergency action plan, its effectiveness and adherence to guidelines are unclear. The risk assessment and management measures for this water resource are also lacking, indicating a need for further attention to ensure the safety and sustainability of Allendale Pond for both the environment and surrounding communities.
