Dd No 103 is a local government-owned flood risk reduction structure located in Dexter, Kansas along Turkey Creek. Designed by Norman L. Roelfs, P.E., this earth dam stands at a height of 48.3 feet and has a length of 1800 feet. Completed in 1983, it provides a storage capacity of 2376.2 acre-feet and serves the primary purpose of flood risk reduction for the surrounding area.

Managed by the Kansas Department of Agriculture, Dd No 103 is regulated, permitted, inspected, and enforced by the state to ensure its structural integrity and safety. Despite being classified with a low hazard potential, the dam is rated as moderate risk level 3 due to its age and condition assessment being not rated. With a spillway width of 120 feet and uncontrolled spillway type, the structure has not been modified in recent years and does not have outlet gates.

Although Dd No 103 has not been assessed for emergency action preparedness or guideline compliance, it remains a crucial infrastructure for managing flood risk in Cowley County, Kansas. As water resource and climate enthusiasts, it is important to monitor and support the maintenance and upkeep of such structures to protect communities and ecosystems from the impacts of extreme weather events and flooding.
