The primary purpose of this dam is for recreation, offering a serene and picturesque setting for outdoor enthusiasts to enjoy.

Despite its low hazard potential, the dam is currently in poor condition, as assessed in 2017. The state-regulated facility is subject to regular inspections, with the last one conducted in May 2017. While the risk assessment indicates a moderate risk level, the dam's emergency action plan and risk management measures are not clearly outlined. With a surface area of 12 acres and a normal storage capacity of 110 acre-feet, Camp Longridge Lake is a valuable resource for the community, yet improvements in maintenance and safety protocols may be necessary to ensure its long-term viability and continued enjoyment for visitors.
