Green Acres Dam, located in Audubon, Iowa, along the TR-East Nishnabotna River, was completed in 1969 by the USDA NRCS. This private dam serves multiple purposes, including fire protection and providing a small fish pond for stock. Standing at 25 feet tall and 492 feet long, the earth dam has a storage capacity of 74 acre-feet, with a surface area of 3 acres and a drainage area of 0.3 square miles.

The dam, regulated by the Iowa DNR, has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk level, the dam has not been inspected recently, and emergency preparedness measures such as an Emergency Action Plan (EAP) are not in place. With a spillway type of "Uncontrolled," the dam is designed to handle maximum discharges, although specific details about outlet gates or locks are not provided. Overall, Green Acres Dam presents an opportunity for further assessment and potential improvements to ensure its long-term safety and functionality for the surrounding area.

For water resource and climate enthusiasts, Green Acres Dam offers a fascinating case study in private dam ownership and management. With its unique location and design features, the dam serves as a vital resource for fire protection and aquatic life support in the region. However, the lack of recent inspections and emergency preparedness measures highlight the importance of ongoing monitoring and maintenance to ensure the dam's continued effectiveness. As climate change impacts water resources, understanding the role of dams like Green Acres in local ecosystems becomes increasingly crucial for sustainable water management practices.
