With a dam height of 10 feet and a length of 100 feet, this earth dam provides a storage capacity of 4950 acre-feet, ensuring a normal storage level of 2750 acre-feet for the surrounding community. The dam's spillway, with a width of 13 feet, is designed as uncontrolled, allowing for efficient discharge during times of excess water flow.
Maintained by the NHDES Dam Bureau, the dam's condition assessment in 2015 deemed it satisfactory, with a significant hazard potential due to its location and storage capacity. Despite this, the risk assessment categorizes it as moderate, with a clear emergency action plan (EAP) in place. The dam is inspected every four years, with the last inspection conducted in October 2019. With its important role in water resource management and recreational activities, the Big Island Pond Walter Stickney Dam remains a vital asset in the region, ensuring both safety and enjoyment for all who benefit from its presence.
