Dd No 4-2, located in Muscotah, Kansas, is a local government-owned Earth-type dam built in 1993 for flood risk reduction purposes along the Muddy Creek-TR river/stream. Designed by GREG MAXWELL, this dam stands at a height of 32 feet with a length of 650 feet, providing a storage capacity of 177.34 acre-feet and a drainage area of 0.6 square miles. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in debris control and flood risk reduction efforts in the region.

Managed by the KS Dept. of Agriculture, Dd No 4-2 has state-regulated and permitted operations, with regular inspections and enforcement measures in place. Despite being uncontrolled, the dam has a spillway width of 40 feet to manage maximum discharges of up to 680 cubic feet per second. The dam's condition is currently not rated, with no Emergency Action Plan (EAP) in place, but its risk management measures are considered moderate.

Dd No 4-2 serves as a vital infrastructure for flood risk reduction in Jackson County, Kansas, and highlights the importance of sustainable water resource management in mitigating climate-related hazards. With its strategic location and design features, this dam exemplifies the collaborative efforts between local governments and regulatory agencies to protect communities and enhance resilience against natural disasters.
