Pond 1a, located in Benton, Tennessee, is a privately owned earth dam completed in 2016 with a primary purpose listed as "Other". The dam stands at a structural height of 41 feet and a hydraulic height of 35 feet, creating a storage capacity of 305 acre-feet. With a surface area of 17.5 acres and a drainage area of 0.04 square miles, Pond 1a plays a crucial role in managing water resources in the region.

Managed by the Tennessee Safe Dams Program, Pond 1a has a significant hazard potential but is currently in satisfactory condition, as indicated by the latest inspection in May 2020. Despite being an uncontrolled spillway type, the dam's risk assessment is moderate. As a vital infrastructure for water resource management, Pond 1a's design by Schnabel Engineering and its compliance with state regulations ensure its operational efficiency and safety, making it an essential asset for climate and water resource enthusiasts to monitor and study in the region.

The dam's location near the Tribhunting Creek and its association with the Nashville District of the USACE highlight the interconnectedness of water resources and climate dynamics in the area. With a strong emphasis on risk management and regulatory compliance, Pond 1a serves as a model for sustainable water resource management in Tennessee. Its role in flood control, water storage, and environmental protection makes it a focal point for researchers and enthusiasts interested in the intersection of water resources and climate resilience.
