Hardin Dam, located in Taylor County, Iowa, is a privately owned structure designed by the USDA NRCS for fire protection, stock, or small fish pond purposes. Completed in 1982, this earth dam stands at 24 feet in height and spans a length of 650 feet, with a maximum storage capacity of 170 acre-feet. The dam's primary purpose is to provide water resources for fire protection and livestock, serving as a crucial water management tool in the area.

Managed by the Iowa Department of Natural Resources, Hardin Dam is regulated and inspected for safety and compliance with state regulations. With a low hazard potential and a moderate risk assessment rating, the dam plays a significant role in mitigating potential risks associated with water resource management in the region. Despite its low hazard potential, the dam's condition is not currently rated, highlighting the need for ongoing monitoring and maintenance to ensure its continued safety and effectiveness in water resource management.

Hardin Dam's location on T-Daugherty Creek, along with its uncontrolled spillway type and soil foundation, contributes to its function as a critical infrastructure for water management in the area. As a point of interest for water resource and climate enthusiasts, the dam's history, design, and purpose offer valuable insights into the importance of sustainable water management practices and the role of dams in supporting local ecosystems and communities.
