Detention Dam No Sp-6, located in El Dorado, Kansas, was completed in 1995 with the primary purpose of flood risk reduction along the East Branch Walnut River. This earth dam, designed by SCS, stands at a height of 18 feet and spans a length of 1080 feet, providing a storage capacity of 156.09 acre-feet. The dam's spillway type is uncontrolled with a width of 50 feet, serving as a crucial debris control and flood risk reduction structure in the region.

Despite being classified as having a low hazard potential, Detention Dam No Sp-6 is rated as having a moderate risk level, indicating a need for ongoing monitoring and maintenance. The dam has not been inspected since its completion in 1995, highlighting the importance of regular assessments to ensure its continued effectiveness in mitigating flood risks. With a surface area of 4.37 acres and a normal storage capacity of 14 acre-feet, this dam plays a vital role in protecting the surrounding area from potential flood events.

As a key component in the local government's flood risk reduction strategy, Detention Dam No Sp-6 serves as a critical infrastructure asset in the region. With its strategic location and design features, including an earth core and buttress structure, the dam provides essential protection against inundation from the East Branch Walnut River. Moving forward, continued monitoring and risk assessment will be essential to ensure the long-term resilience and effectiveness of this important water resource management facility.
