De Louis Dam, located in Appanoose County, Iowa, is a privately owned structure primarily used for fire protection, stock watering, and as a small fish pond. Constructed in 1992 by the Soil Conservation Service (SCS), this earth dam stands at a height of 29 feet and stretches 340 feet in length. With a storage capacity of 17 acre-feet and a surface area of 1.8 acres, the dam serves the surrounding area by regulating water flow in the TR-SHOAL CREEK.

Managed by the Iowa Department of Natural Resources (DNR), the De Louis Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Although the dam has not been inspected recently, it is regulated, permitted, and inspected by the state authorities. The risk assessment for the dam is moderate, indicating the need for ongoing risk management measures to ensure its safety and functionality for the community it serves.

In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) in place. However, with its controlled spillway and overall low hazard potential, the De Louis Dam continues to play a vital role in water resource management and climate resilience efforts in the region.
