Dd No 5 (Dreyer) is a local government-owned dam located in Leroy, Kansas, designed by the USDA NRCS and regulated by the Kansas Department of Agriculture. Completed in 1986, this earth dam stands at a height of 21 feet and serves the primary purpose of flood risk reduction along the South Big Creek-TR. With a storage capacity of 280.82 acre-feet and a surface area of 11.03 acres, Dd No 5 plays a crucial role in managing water resources in the area.

Despite being classified as having a low hazard potential, Dd No 5 faces a moderate risk assessment rating due to its location and structural characteristics. The dam, with its uncontrolled spillway type and lack of outlet gates, presents a unique set of challenges for risk management. While the dam has not been rated for its condition assessment, it is essential for local authorities to regularly monitor and maintain this critical infrastructure to ensure its continued functionality and safety.

As climate change continues to impact water resources and increase the frequency of extreme weather events, the importance of well-maintained dams like Dd No 5 becomes even more pronounced. With its role in flood risk reduction and water management, this dam serves as a vital asset for the community and underscores the need for proactive risk management and emergency preparedness in the face of changing environmental conditions.
