Heeren Dam, located in Dumont, Iowa, is a privately owned earth dam built in 1969 by the USDA NRCS. The dam's primary purpose is for fire protection, stock, or as a small fish pond. It stands at a height of 20 feet and stretches 700 feet in length, with a storage capacity of 70 acre-feet. The dam is situated on the TR-Hargrave Creek, within the jurisdiction of the Iowa DNR, and is regulated, permitted, inspected, and enforced by the state.

With a low hazard potential and a moderate risk assessment rating of 3, Heeren Dam has not been formally rated for its condition assessment. It does not have an emergency action plan in place or updated inundation maps. Despite these limitations, the dam continues to serve its intended purposes effectively and plays a key role in water resource management in the area. For water resource and climate enthusiasts, Heeren Dam offers a fascinating case study in the intersection of private ownership, state regulation, and the importance of infrastructure for fire protection and ecological conservation.
