With a height of 32 feet and a length of 1200 feet, this dam has a storage capacity of 2000 acre-feet and a maximum discharge of 2900 cubic feet per second. While its primary purpose is unspecified, the dam serves as a critical water resource infrastructure in the area.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Triple 7 Ranch Dam is regulated, permitted, inspected, and enforced by the state agency. Despite being rated as having a low hazard potential, the dam's condition has not been officially assessed. In case of any emergency, however, the dam does not have an Emergency Action Plan (EAP) in place, which may be a concern for stakeholders and nearby residents. With its strategic location and historical significance, Triple 7 Ranch Dam plays a vital role in water resource management and climate resilience efforts in the region.
While the dam's specific purposes and modifications over the years remain unknown, its presence on Dry Creek contributes to the overall water management infrastructure in South Dakota. As water resource and climate enthusiasts continue to monitor and assess the condition of Triple 7 Ranch Dam, collaboration between private owners, state agencies, and local communities will be essential to ensure the long-term safety and effectiveness of this important water resource structure.
