Dozark Dam, located in Arion, Iowa, along the TR-Boyer River, was completed in 1977 and is privately owned. Designed by USDA NRCS, the earth dam stands at a height of 32 feet and spans 405 feet in length, with a storage capacity of 79 acre-feet and a surface area of 5.3 acres. The dam primarily serves the purposes of fire protection, stock, and a small fish pond, with low hazard potential and a moderate risk assessment rating.

Managed by the Iowa Department of Natural Resources, Dozark Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and compliance with regulations. The dam's spillway is uncontrolled, and it has a drainage area of 0.31 square miles. While the condition assessment is currently not rated, the risk management measures are in place to address any potential hazards associated with the dam. The dam is considered to have a moderate risk level, and emergency action plans have been prepared to mitigate any potential risks effectively.

For water resource and climate enthusiasts, Dozark Dam offers a fascinating glimpse into the intersection of human infrastructure and natural resources. With its vital role in fire protection and water storage, as well as its location on the TR-Boyer River, the dam serves as a critical component of the local ecosystem. As efforts continue to monitor and maintain the dam's safety, it stands as a testament to the importance of responsible water resource management in the face of changing climates and environmental challenges.
