Arrasmith Dam, located in Buffalo County, Nebraska along the South Loup River, stands as a crucial structure for flood risk reduction in the region. Built in 1960, this earth dam with a height of 21.8 feet and a length of 470 feet provides essential protection to the surrounding area, with a normal storage capacity of 30.2 acre-feet and a maximum discharge capability of 920 cubic feet per second. The dam, designed by USDA NRCS, serves as a testament to the collaboration between private owners and government agencies to ensure the safety and resilience of the local community.

Managed by the Nebraska Department of Natural Resources, Arrasmith Dam is subject to state regulation, inspection, and enforcement to maintain its structural integrity and operational effectiveness. While the dam's condition was last assessed in 2014 and deemed "Not Rated," its importance in mitigating flood risks remains paramount. With its strategic location and design, the dam contributes to the overall water resource management efforts in the area, highlighting the critical role of such infrastructure in adapting to changing climate patterns and safeguarding communities from natural disasters.

As water resource and climate enthusiasts, understanding the significance of Arrasmith Dam goes beyond its physical attributes. It symbolizes the intersection of engineering, conservation, and public safety, demonstrating how human ingenuity can harmonize with natural landscapes to create sustainable solutions for water management. By recognizing the value of structures like Arrasmith Dam and advocating for their continued maintenance and improvement, we can enhance our resilience to climate challenges and build a more secure future for generations to come.
