Cozad Dam, located in Red Rock Reservoir in Iowa, was completed in 1959 and serves multiple purposes, including fire protection, stock, and small fish pond management. Owned privately, the dam is regulated by the Iowa Department of Natural Resources and is designed by the USDA NRCS. With a height of 36 feet and a length of 606 feet, the earth dam stands as a crucial structure for water resource management in the area.

With a storage capacity of 339 acre-feet and a surface area of 18 acres, Cozad Dam plays a vital role in managing water resources for the local community. The dam's low hazard potential and moderate risk assessment make it a reliable infrastructure for ensuring water security in the region. While the dam's condition has not been rated recently, its design and construction by the Natural Resources Conservation Service indicate a commitment to safety and efficiency in water management.

Despite its age, Cozad Dam continues to be a key component in the water infrastructure of Clarke County, Iowa. With its regulated state jurisdiction, regular inspections, and low hazard potential, the dam stands as a testament to effective water resource management. As climate change impacts water availability, structures like Cozad Dam are essential for ensuring sustainable water use for future generations.
