Orchard Dam, is a private-owned structure located in Oconee, South Carolina. Designed by USDA NRCS and completed in 1985, this Earth-type dam serves primarily for irrigation purposes on the TR-Persimmon Branch. With a height of 37 feet and a length of 310 feet, the dam has a storage capacity of 33 acre-feet, providing essential water resources for the surrounding area.
Despite its low hazard potential, the dam's condition assessment is rated as poor, highlighting the need for maintenance and potential improvements. The last inspection in April 2017 revealed areas of concern, prompting a moderate risk assessment. The dam is regulated by the SC DHEC and undergoes regular state inspection and enforcement to ensure its structural integrity and safety.
For water resource and climate enthusiasts, H H Moore Dam presents an intriguing case study in the management of private-owned dams for irrigation purposes. Its location in a scenic area of South Carolina adds to its significance, making it a focal point for discussions on water conservation, infrastructure maintenance, and risk management in the face of changing climate conditions.
