Dd Iv-12 is a local government-owned dam located in Fort Scott, Kansas, designed for flood risk reduction along Mill Creek-TR. Completed in 1998, the earth dam stands at 19 feet tall and spans 1250 feet in length, with a storage capacity of 338.1 acre-feet. Despite its low hazard potential and moderate risk assessment rating, the dam has not been rated for its current condition, highlighting a potential area for further assessment and maintenance.

The dam features an uncontrolled spillway with a width of 40 feet, capable of handling a maximum discharge of 800 cubic feet per second. With its primary purpose being flood risk reduction, Dd Iv-12 plays a crucial role in protecting the surrounding Bourbon County from potential flooding events. The dam's location in a regulated state with permitting, inspection, and enforcement processes in place ensures its compliance with safety standards and regulations, contributing to its overall operational effectiveness.

As a key infrastructure within the Tulsa District of the US Army Corps of Engineers, Dd Iv-12 serves as a vital component in the region's water resource management system. With its strategic positioning and design features, the dam not only mitigates flood risks but also supports the sustainable use of water resources in the area. For water resource and climate enthusiasts, Dd Iv-12 presents an interesting case study in dam engineering and management, showcasing the intersection of infrastructure, environmental protection, and community resilience in the face of changing climate conditions.
