Sheppard, a private dam located in Union Township, Pennsylvania, serves as a recreational site along the TR South Branch Conewago Creek. Built in 1934, this earthen dam stands at a height of 23 feet and has a length of 300 feet, providing a storage capacity of 89 acre-feet. Despite its age, Sheppard has a low hazard potential and has not been rated for its condition assessment.

Managed by the Pennsylvania Department of Environmental Protection, Sheppard is regulated, permitted, inspected, and enforced by state authorities. The dam, primarily designed for recreation, has not undergone any significant modifications since its construction. It is situated within Adams County, Pennsylvania, and falls under the jurisdiction of the Baltimore District of the US Army Corps of Engineers.

Water resource and climate enthusiasts may find Sheppard an interesting case study due to its historical significance, design characteristics, and regulatory framework. As a privately owned structure with state oversight, Sheppard showcases the importance of maintaining and monitoring dams for both recreational and safety purposes in the face of changing environmental conditions and increasing water resource demands.
