Perdue Dam, located in Red Oak, Iowa, along the TR-East Nishnabotna River, was completed in 1998 and serves multiple purposes including fire protection, stock water supply, and small fish pond management. Owned privately, the dam was designed by the USDA NRCS and stands at a height of 28 feet with a length of 320 feet. The dam has a storage capacity of 17 acre-feet and covers a surface area of 2 acres, serving a drainage area of 0.29 square miles.

With a low hazard potential and a moderate risk assessment rating, Perdue Dam is classified as an earth dam built on soil foundations. The dam features an uncontrolled spillway and has not been modified since its completion. While the condition assessment is currently marked as "Not Rated," the dam's risk management measures and emergency action plan status are unknown. The dam is not regulated by the state and does not have an established inspection, enforcement, or permitting process, making it crucial for private owners to monitor the structure's integrity and safety proactively.
