The Arnburg Dam in Iowa, completed in 1997, serves multiple purposes including fire protection, stock watering, and creating a small fish pond. Owned privately and regulated by the Iowa Department of Natural Resources, this earth dam stands at a height of 35 feet and spans a length of 277 feet, with a storage capacity of 55 acre-feet. Located in Dallas County, the dam is situated on TR- Coal Creek and is designed by the NRCS.

With a low hazard potential and a moderate risk assessment rating, the Arnburg Dam plays a crucial role in water management in the area. While the dam has not been rated for its condition, it is regularly inspected, permitted, and enforced by the state agencies to ensure its safety and functionality. Despite its relatively small surface area of 3 acres, the dam contributes to the environmental and agricultural needs of the region, showcasing the importance of sustainable water resource management in the face of changing climate patterns.
