Sheppard Myers is a vital water resource facility located in West Manheim Township, York, Pennsylvania. Managed by the local government, this earth dam was completed in 1933 and serves the primary purpose of water supply, with a storage capacity of 1,213 acre-feet. The dam stands at 38 feet tall and spans a length of 760 feet, impounding the waters of the South Branch Conewago Creek.

Despite its critical role in water supply, Sheppard Myers poses a high hazard potential and has been rated as having poor condition. It falls under the regulatory oversight of the Pennsylvania Department of Environmental Protection, with state permitting, inspection, and enforcement in place to ensure its safety. The dam's last inspection in March 2021 revealed the need for improvement, highlighting the importance of regular monitoring and maintenance to mitigate risks and safeguard the surrounding community.

With its historical significance as a water resource infrastructure in Pennsylvania, Sheppard Myers stands as a reminder of the importance of sustainable water management practices and the ongoing need for investment in dam safety. As climate change continues to impact water resources, ensuring the resilience and functionality of structures like Sheppard Myers is crucial for mitigating risks and maintaining a reliable water supply for the region.
