Mc Aninch Dam, located in Warren County, Iowa, is a privately owned structure designed by the USDA NRCS and regulated by the Iowa DNR. Completed in 1981, this earth dam stands at 27 feet tall and stretches 350 feet in length, serving primarily for fire protection, stock, or small fish pond purposes. With a maximum storage capacity of 80 acre-feet and a surface area of 4.8 acres, the dam sits on the TR- Middle R. river/stream, contributing to flood control and water resource management in the area.

Despite its low hazard potential, Mc Aninch Dam poses moderate risk, emphasizing the importance of regular inspections and adherence to safety guidelines. While the condition assessment remains unrated and certain emergency preparedness measures are lacking, the dam plays a crucial role in water conservation and management efforts in the region. As a key feature of the Red Rock Reservoir area, the dam's impact on the local ecosystem and water supply underscores the need for continued monitoring and maintenance to ensure its long-term viability and safety for both human and environmental interests.

With its uncontrolled spillway and soil foundation, Mc Aninch Dam represents a vital piece of infrastructure for the community, supporting agricultural activities, wildlife habitats, and recreational opportunities. As climate change brings about more frequent and intense weather events, the dam's role in mitigating flood risks and preserving water resources becomes increasingly significant. By staying vigilant in its upkeep and management, Mc Aninch Dam stands as a testament to the intersection of human ingenuity and environmental stewardship in safeguarding our waterways for future generations.
