Located in Mt. Sterling, Iowa, Wheaton Dam is a privately owned structure designed by the USDA NRCS to address flood risk reduction along the TR-Fox River. This earth dam stands at a height of 27 feet with a length of 450 feet, offering a storage capacity of 91 acre-feet and serving multiple purposes such as debris control and grade stabilization in addition to flood risk reduction. The dam's spillway, with a width of 12 feet, is uncontrolled, and the overall hazard potential is rated as low.

Managed by the Iowa Department of Natural Resources, Wheaton Dam is situated in Davis County and falls under the regulatory jurisdiction of the state. While the dam's condition assessment is currently not rated, it poses a moderate risk level of 3, prompting the need for ongoing risk management measures. With a drainage area of 0.4 square miles and a surface area of 4 acres, Wheaton Dam plays a crucial role in safeguarding the surrounding area from potential flooding events. Despite not being operated by the US Army Corps of Engineers, the dam's strategic location and design highlight its significance in water resource management and climate resilience efforts.
