Smith Dam, located in Sac County, Iowa, on the TR-Raccon River, was completed in 2015 and serves as a vital structure for flood risk reduction in the area. Owned privately, the dam stands at a height of 33 feet with a length of 290 feet, providing storage capacity of 59 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Smith Dam plays a crucial role in mitigating flood risks in the region.

Managed by the Iowa Department of Natural Resources and regulated by the state, Smith Dam undergoes regular inspections and is subject to state permitting and enforcement. Despite not having a designated spillway type or width, the dam's primary purpose remains flood risk reduction, with a normal storage capacity of 12 acre-feet. The dam's earth structure with a stone core foundation ensures its durability and effectiveness in managing water resources in the area.

Although Smith Dam does not fall under the jurisdiction of the US Army Corps of Engineers, it plays a significant role in water resource management in Iowa. With its strategic location and design focused on flood risk reduction, Smith Dam stands as a testament to the importance of sustainable water infrastructure in addressing climate challenges and protecting communities from potential water-related disasters.
