Clinton Dam in Denison, Iowa, is a privately owned structure designed by NRCS with a primary purpose of flood risk reduction. Completed in 2008, this earth dam stands at a height of 22 feet and spans 552 feet in length, providing a storage capacity of 82 acre-feet. Situated on the Trib East Boyer River, the dam serves to mitigate flooding in the area, with a hazard potential rated as low and a moderate risk assessment.

Managed by the Iowa Department of Natural Resources, Clinton Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. While the dam currently holds a condition assessment of "Not Rated" and lacks detailed emergency action plans, it plays a crucial role in protecting the surrounding Crawford County community from potential flood events. Water resource and climate enthusiasts can appreciate the vital role that Clinton Dam plays in managing water flow and reducing flood risks in the region.
