Dd No 45, located in Marysville, Kansas, is a local government-owned dam designed by CES Group, PA primarily for flood risk reduction along the Horseshoe Creek-TR. Completed in 2012, this earth dam stands at 33 feet high with a hydraulic height of 21 feet and a length of 663 feet, providing a storage capacity of 110 acre-feet and a maximum discharge of 566 cubic feet per second. Despite its low hazard potential and moderate risk assessment, the dam's condition is currently not rated, highlighting the need for regular inspections and risk management measures to ensure its continued effectiveness in flood control.

The dam, with its uncontrolled spillway and buttress core type, serves as a critical infrastructure in the region, protecting surrounding areas from potential flooding events. Its location in Marshall County, Kansas, underscores its importance in managing water resources and climate-related risks in the area. With a surface area of 6 acres and a drainage area of 0.34 square miles, Dd No 45 plays a vital role in safeguarding the community against the impacts of extreme weather events and ensuring the resilience of the local water supply.

As a key component in the flood risk reduction strategy for the region, Dd No 45 serves as a testament to the collaborative efforts of local government agencies and designers in addressing the challenges posed by climate change. With its construction aimed at mitigating potential flood hazards and protecting the community from water-related disasters, the dam underscores the critical role of infrastructure in ensuring the sustainable management of water resources and enhancing climate resilience in the face of evolving environmental conditions.
