Dd No 111 is a local government-owned dam located in Lawrence, Kansas, designed by Speaker & King in 1988 for the primary purpose of flood risk reduction along Elk Creek. This earth dam stands at 37 feet high and spans 635 feet in length, with a storage capacity of 394 acre-feet and a drainage area of 1.28 square miles. Its spillway, with a width of 45 feet, is of the uncontrolled type, and the dam has a low hazard potential rating.

With a moderate risk assessment score of 3, Dd No 111 is regulated, inspected, permitted, and enforced by the Kansas Department of Agriculture. Despite not having a condition assessment rating, the dam is operational and serves its purpose effectively. It has not undergone any modifications or inspections in recent years, but its emergency action plan status and adherence to guidelines are unclear. Overall, Dd No 111 plays a crucial role in mitigating flood risks in the area and ensuring the safety of the surrounding communities.
