Dd No 109, also known as Middle Creek WS Joint District No 62, is a local government-owned dam located in Elmdale, Kansas. Managed by the Kansas Department of Agriculture, this dam serves the primary purpose of flood risk reduction along Wildcat Creek-TR. Built with an earth core and buttress design, Dd No 109 stands at a height of 42 feet and has a storage capacity of 422 acre-feet.

With a low hazard potential and a moderate risk assessment rating, Dd No 109 plays a crucial role in protecting the surrounding area from potential flooding events. Despite its age and lack of recent inspection data, this dam remains a vital piece of infrastructure in the Chase County water resource management system. As climate change continues to impact water resources, the importance of maintaining and monitoring structures like Dd No 109 becomes increasingly apparent for the resilience of local communities.
