Dd No 12-4 is a local government-owned dam located in Severance, Kansas, designed by Speaker & King and completed in 1984. This earth-type dam serves the primary purpose of flood risk reduction along the Wolf River-TR stream. With a height of 41 feet and a length of 500 feet, the dam has a storage capacity of 121.7 acre-feet, with a normal storage level of 60.3 acre-feet. The dam has a low hazard potential and is currently in a not rated condition assessment.

Managed by the Kansas Department of Agriculture, Dd No 12-4 is regulated, permitted, inspected, and enforced by the state authorities to ensure its safety and functionality. The dam has a spillway width of 60 feet and is classified as uncontrolled. Despite being a local-level structure, the dam plays a crucial role in mitigating flood risks in the Brown County area of Kansas. With a moderate risk level (3) identified, it is essential for ongoing risk management measures to be implemented for the continued safety and effectiveness of the dam.
