Hulm, located in Ziebach, South Dakota, is a privately owned dam on the TR MOREAU river with a height of 18 feet and a length of 600 feet. Constructed in 1956 by the Natural Resources Conservation Service, this earth dam has a storage capacity of 162 acre-feet and a maximum discharge rate of 3150 cubic feet per second. Despite its low hazard potential, Hulm is regulated by the South Dakota Department of Environment and Natural Resources and undergoes regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations.

With its primary purpose unspecified, Hulm serves as a vital water resource for the region, providing storage for irrigation, livestock, and domestic water supply. The dam's normal storage capacity of 97 acre-feet supports the local ecosystem and agricultural activities in the area. While its condition assessment is currently listed as "Not Rated," Hulm's emergency action plan status, risk assessment, and hazard mitigation measures are not specified in the available data. However, its strategic location and controlled release capabilities make it an essential infrastructure for water management and climate resilience efforts in South Dakota.

Managed by private owners, Hulm plays a crucial role in water management and flood control within the St. Paul District. The dam's presence ensures water security and resource sustainability for the surrounding communities, with Dusty Johnson (R) representing the area in Congress. As climate change impacts continue to affect the region, Hulm stands as a testament to the importance of resilient water infrastructure and proactive risk management in safeguarding our water resources for future generations.
