Dd No 11b, located in Rice County, Kansas, is a local government-owned dam constructed in 2000 for the primary purpose of flood risk reduction along the Little Arkansas River. This earth dam stands at a height of 26 feet and stretches 1462 feet in length, with a storage capacity of 2097 acre-feet and a drainage area of 7.29 square miles. Despite being classified as having low hazard potential and a moderate risk assessment, the dam has not been rated for its current condition.

With a spillway width of 175 feet and maximum discharge capacity of 4492 cubic feet per second, Dd No 11b plays a crucial role in managing water flow during heavy rainfall events. The dam's strategic location and design make it a vital infrastructure for protecting surrounding areas from potential flooding. While it has not been inspected since its completion in 2000, the dam is still considered to be in operational condition.

For water resource and climate enthusiasts, Dd No 11b serves as an important example of local government efforts to mitigate flood risks and manage water resources in the face of changing climate patterns. Understanding the design and function of such dams is crucial for developing sustainable water management strategies and ensuring the safety of communities in flood-prone regions. As the climate continues to evolve, the role of structures like Dd No 11b will only become more critical in safeguarding against the impacts of extreme weather events.
