Constructed in 1955 by the Natural Resources Conservation Service, this Earth-type dam stands at a height of 20 feet and has a length of 450 feet. With a storage capacity of 70 acre-feet and a maximum discharge of 1080 cubic feet per second, Jones serves as a vital water resource for the region.

Despite being rated as having a low hazard potential and not having a current condition assessment, Jones is regulated and permitted by the South Dakota Department of Environment and Natural Resources. The dam undergoes regular inspections, with state enforcement and permitting processes in place to ensure its safety and compliance with regulations. While the dam has not been modified in recent years, it remains a crucial infrastructure for water management in the area.

Jones plays a crucial role in water resource management in South Dakota, providing storage for 35 acre-feet of water and serving as a key piece of infrastructure for flood control and water supply. With its strategic location and well-maintained structure, Jones continues to contribute to the region's resilience to climate challenges and ensures the sustainable use of water resources for years to come.
