Dd No M-9, located in Ottawa, Kansas, is a crucial flood risk reduction structure managed by the local government with oversight from the Kansas Department of Agriculture. This earth dam, completed in 1987, stands at a height of 21.5 feet and spans 790 feet in length, offering protection to the surrounding area from potential flooding events. With a storage capacity of 147.8 acre-feet and a surface area of 2.87 acres, Dd No M-9 plays a vital role in managing water flow along Mud Creek-TR.

Despite its importance, Dd No M-9 has been assessed as being in poor condition, with a high hazard potential. The dam lacks outlet gates and operates with an uncontrolled spillway, contributing to its risk profile. Regular inspections are conducted every three years, with the last inspection taking place in January 2020. As climate change continues to impact weather patterns and increase the frequency of extreme events, the maintenance and upkeep of structures like Dd No M-9 become even more critical to ensure the safety and protection of the local community.

Efforts to address the dam's condition and potential risks are ongoing, with a moderate risk assessment score of 3 highlighting the need for continued monitoring and management. As water resource and climate enthusiasts, staying informed about the status of Dd No M-9 and similar structures is key to understanding the intersection of water management, infrastructure resilience, and climate adaptation in the face of a changing environment.
