Located in Harding, South Dakota, the Barn dam stands as a testament to the region's commitment to water resource management and climate resilience. Completed in 1946, this earth dam sits on the Tributary South Fork Grand River, providing crucial water storage capacity for the area. With a height of 20 feet and a length of 735 feet, the dam has a maximum storage capacity of 90 acre-feet, supporting irrigation and flood control efforts in the region.

Managed by the South Dakota Department of Environment and Natural Resources (DENR), the Barn dam is classified as low hazard potential with a current condition assessment of "Not Rated." While the dam is regularly inspected and maintained by state authorities, its emergency action plan (EAP) status is currently unspecified. As climate change continues to impact water resources, the importance of infrastructure like the Barn dam in ensuring water security for South Dakota cannot be understated.

With Congressman Dusty Johnson representing the area in the U.S. House of Representatives, the Barn dam serves as a critical piece of the local water resource management puzzle. As enthusiasts of water resources and climate resilience, the Barn dam stands as a symbol of the ongoing efforts to safeguard vital water supplies in the face of a changing climate.
