Located in Jerauld County, South Dakota, the Dwyer dam is a privately owned structure that serves multiple important functions for the surrounding area. Completed in 1966, this earth dam stands at a height of 33 feet and has a storage capacity of 80 acre-feet, with a normal storage level of 55 acre-feet. The dam is situated on the TR James River and is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets all necessary safety and environmental standards.

Despite being classified as a low-hazard potential structure, the condition of the Dwyer dam has not been rated in recent assessments. This raises questions about the current state of the dam and whether any maintenance or upgrades may be needed to ensure its continued functionality. Given its importance for water resource management in the area, it is crucial for stakeholders to stay informed about the dam's condition and any potential risks associated with it. As climate change continues to impact water resources, ensuring the safety and efficiency of structures like the Dwyer dam is more vital than ever.

With a maximum discharge capacity of 100 cubic feet per second, the Dwyer dam plays a key role in flood control and water supply management in the region. As such, it is essential for local authorities and private owners to work together to maintain and monitor the dam effectively. By staying proactive in their approach to dam safety and management, they can help mitigate potential risks and ensure the long-term sustainability of this important water resource infrastructure in South Dakota.
