Diamond D Pond Dam, also known as Beer Can Pond Dam, is a privately owned structure located in Spartanburg, South Carolina. Built in 1959 by the USDA NRCS, this earthen dam stands at a height of 25 feet and spans 210 feet in length, creating a storage capacity of 39 acre-feet for recreational use. Situated on Thompson Creek, the dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC) and is designed with an uncontrolled spillway.

Despite its low hazard potential, the dam's condition assessment in 2017 revealed poor maintenance, raising concerns about its structural integrity. The risk assessment has categorized the dam as moderate, indicating a potential need for risk management measures. With a history of irregular inspections and no emergency action plan in place, there is a call for improved maintenance and emergency preparedness to ensure the safety of the surrounding community and the ecological health of Thompson Creek. Water resource and climate enthusiasts should keep a close eye on Diamond D Pond Dam for updates on its rehabilitation and regulatory compliance.
