Gs Dd No D-39 is a local government-owned earth dam located in Jackson, Kansas, along the South Cedar Creek. Designed by Greg Maxwell, this dam serves as a crucial flood risk reduction structure in the area. With a height of 39.4 feet and a storage capacity of 430 acre-feet, it plays a significant role in managing water flow and protecting the surrounding communities from potential flooding events.

Managed by the Kansas Department of Agriculture, Gs Dd No D-39 has a low hazard potential and a moderate risk assessment rating. While the dam has not been rated for its condition, it is regularly inspected, permitted, and enforced by the state regulatory agency. The presence of an uncontrolled spillway with a width of 55 feet ensures effective water release during high flow events, further enhancing the dam's flood risk reduction capabilities.

Despite its simple structure and design, Gs Dd No D-39 remains a vital component of the local water resource management system. With its strategic location along the South Cedar Creek and its ability to store and release water efficiently, this dam exemplifies the importance of proactive flood risk reduction measures in mitigating the impacts of extreme weather events and ensuring the safety and well-being of the community.
