Korn Dam, located in Vail, Iowa, was completed in 1959 by the USDA NRCS and remains privately owned with a primary purpose of fire protection, stock, or small fish pond. This earth dam, standing at 26 feet tall and stretching 510 feet in length, serves as a vital water resource on the TR-Boyer River, providing a maximum storage capacity of 73 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition and has not undergone a recent inspection since 1964.

Managed by the Iowa DNR, Korn Dam is regulated, permitted, inspected, and enforced by the state, ensuring its safety and compliance with regulations. The dam's spillway is uncontrolled, with no outlet gates or locks present. While it currently poses a moderate risk, the dam's risk management measures and emergency preparedness plans are not well-documented, indicating a potential area for improvement in terms of ensuring the safety of downstream communities in the event of a dam failure. Water resource and climate enthusiasts may find Korn Dam's historical significance and structural features intriguing, as it continues to play a crucial role in the local ecosystem and community water supply.
