The dam stands at 22 feet high and has a storage capacity of 70 acre-feet, with a normal storage level of 55 acre-feet. It spans a length of 280 feet and is classified as an earth dam, serving as a critical component in regulating a tributary of the Cheyenne River.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Streeter Dam is subject to state regulations for permitting, inspection, and enforcement. With a significant hazard potential, the dam's condition assessment is currently listed as "Not Rated," highlighting the importance of continued monitoring and maintenance to ensure its structural integrity and public safety. While the dam has not been modified in recent years and lacks certain emergency preparedness measures, such as an Emergency Action Plan (EAP) and inundation maps, its presence underscores the importance of sustainable water resource management in the region.
Despite its age, Streeter Dam remains a vital infrastructure for water storage and regulation in the area, playing a crucial role in flood control and irrigation. As climate change impacts continue to affect water resources, the dam's significance in mitigating potential risks and ensuring water security for the surrounding community becomes increasingly apparent. With the involvement of state regulators and local representatives, efforts to assess and address the dam's condition and emergency preparedness measures will be essential to its continued functionality and resilience in the face of changing environmental conditions.
