Ulmer Dam
May 7, 2024
Ulmer Dam, located in Hutchinson, South Dakota, along a tributary of the James River, is a privately owned structure that has been in operation since its completion in 1975. Managed by the Natural Resources Conservation Service, this earth dam stands at 31 feet in height and spans a length of 310 feet, providing a storage capacity of 108 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Ulmer Dam is a crucial component of water resource management in the region.
Despite lacking detailed information on its primary purpose and specific design features, Ulmer Dam plays a significant role in regulating and safeguarding the surrounding area. With state oversight and regulatory agencies ensuring its compliance with safety standards, the dam is equipped to handle a maximum discharge of 3,793 cubic feet per second. While its emergency action plan status and risk assessment remain undisclosed, the dam's strategic location and functionality make it a key asset for water resource and climate enthusiasts interested in the region's hydrological infrastructure.
As a part of the St. Paul District under the US Army Corps of Engineers, Ulmer Dam contributes to the overall water management efforts in South Dakota, serving as a vital resource for irrigation, flood control, and environmental conservation. With its modest size and capacity, the dam may not attract widespread attention, but its role in maintaining water supply reliability and protecting downstream communities underscores its importance in the broader context of water resource management and climate resilience.
