Mountain Dam, located in Warren County, Iowa, is a privately owned earth dam constructed in 1974 by the USDA NRCS for fire protection, stock, and small fish pond purposes. With a height of 33 feet and a length of 350 feet, this dam has a storage capacity of 34 acre-feet and covers a surface area of 3.3 acres. It is regulated by the Iowa DNR and is situated on TR-Broadhorn Creek, within the jurisdiction of the state.

Despite being classified as having a low hazard potential and a moderate risk assessment, Mountain Dam has not been rated for its condition assessment. The dam does not have an Emergency Action Plan (EAP) in place, and there is no information available on its last inspection date or inspection frequency. However, it is reassuring to note that the dam meets state regulatory standards and undergoes state permitting, inspection, and enforcement to ensure its safety and compliance with regulations. For water resource and climate enthusiasts, Mountain Dam presents an interesting case study of a privately owned dam that serves multiple purposes while being subject to state oversight and regulation.
