Constructed in 1992 by the USDA NRCS, this earth dam stands at a height of 28 feet and spans 412 feet in length. With a storage capacity of 35 acre-feet and serving a drainage area of 0.15 square miles, this structure plays a crucial role in flood risk reduction along the TR- South Soap Creek.

Managed by the Iowa DNR, Soap Creek Watershed Site 4-54 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as having a low hazard potential, the dam's risk assessment is moderate. While the condition assessment is currently not rated, the structure's risk management measures and emergency preparedness protocols are yet to be fully documented. Overall, this site presents an intriguing case study for water resource and climate enthusiasts interested in the intersection of dam infrastructure, environmental protection, and public safety in rural Iowa.
