Located in Pike, Pennsylvania, Decker Swamp is a state-owned recreational area built in 1951 for the primary purpose of providing leisure activities for water resource and climate enthusiasts. The dam at Decker Swamp is an earth-type structure standing at 11 feet high and stretching 720 feet in length. With a storage capacity of 958 acre-feet and a surface area of 119 acres, the reservoir formed by the dam plays a vital role in the local ecosystem by providing a habitat for various species of wildlife.

Despite its importance, Decker Swamp is currently assessed as being in poor condition, with a low hazard potential. The Pennsylvania Department of Environmental Protection oversees the regulation, inspection, and enforcement of the dam, ensuring its safety and reliability. The last inspection in July 2019 highlighted the need for maintenance and improvement to enhance the structure's resilience and sustainability. For water resource enthusiasts, Decker Swamp offers a unique opportunity to explore the intersection of human infrastructure and natural ecosystems, making it a valuable site for research and conservation efforts in the face of a changing climate.
