West Fork Big Creek Watershed Site B-51 is a vital structure located in Ringgold County, Iowa, designed by the USDA NRCS for fire protection, stock, or small fish pond purposes as well as flood risk reduction. Completed in 1992, this earthen dam stands at 24 feet in height, with a length of 415 feet, and a storage capacity of 78 acre-feet. With a low hazard potential and a moderate risk assessment rating, this site is owned by the local government and regulated by the Iowa DNR, ensuring its safety and compliance with state regulations.

Situated along the TR- West Fork Big Creek, this watershed site plays a crucial role in managing water resources in the region, with a drainage area of 0.26 square miles and a surface area of 3.6 acres. Despite not being rated for condition assessment, the dam's design and construction by the Natural Resources Conservation Service highlight its resilience and effectiveness in mitigating flood risks and protecting the surrounding environment. The presence of an uncontrolled spillway and its strategic location in a high-risk flood area make it a key asset for water resource and climate enthusiasts to monitor and study.

As part of the Rock Island District, West Fork Big Creek Watershed Site B-51's significance extends beyond its primary purposes, serving as a valuable resource for the community and wildlife. With its location in a state-regulated area and the involvement of federal agencies like the USDA NRCS, this site exemplifies collaborative efforts to manage and protect water resources in Iowa. Its history, design features, and risk assessment provide a fascinating case study for those interested in sustainable water management practices and climate resilience strategies in the Midwest.
