Allen- Ewing Dam, located in Wayne County, Iowa, is a privately owned earth dam with a primary purpose of fire protection, stock, or small fish pond. Completed in 1999 by the USDA NRCS, this dam stands at a height of 35 feet and stretches 632 feet in length, with a storage capacity of 54 acre-feet. Situated in the Rathbun Reservoir area, the dam plays a crucial role in regulating water flow from the TR- West Jackson Creek, helping to manage the drainage area of 0.05 square miles.

Despite being classified as having a low hazard potential, Allen- Ewing Dam is subject to state regulation and inspection by the Iowa DNR. The dam has not been rated for its condition assessment, but it is considered to have a moderate risk level. While the dam does not have a formal Emergency Action Plan (EAP) in place, it meets regulatory guidelines and has emergency contacts on file. With its uncontrolled spillway type and stone core structure, Allen- Ewing Dam serves as a vital component in the water resource management of the area, ensuring the safety and sustainability of the surrounding environment.

For water resource and climate enthusiasts, Allen- Ewing Dam presents an intriguing case study in dam engineering and management. Its location in an ecologically significant area, combined with its role in fire protection and stock pond maintenance, underscores the intersection between human infrastructure and natural ecosystems. With its low hazard potential and moderate risk assessment, the dam poses interesting questions about risk management and emergency preparedness in the face of changing climate patterns. As we continue to grapple with water resource challenges, Allen- Ewing Dam stands as a testament to the importance of sustainable water management practices in safeguarding our environment for future generations.
