Duane Davis is a private dam located in Princeton, Iowa, designed by the USDA NRCS in 1991 for grade stabilization purposes. This Earth dam stands at a height of 27 feet and stretches 380 feet in length, with a storage capacity of 21 acre-feet. Situated on Tr- Caleb Creek in Wayne County, Iowa, Duane Davis serves multiple functions including fire protection, stock watering, and small fish pond maintenance.

Despite its low hazard potential, Duane Davis poses a moderate risk due to its location and design. The dam's uncontrolled spillway and outlet gates contribute to its risk assessment rating of 3 out of 5. However, with no recent inspection data available, the condition assessment and emergency preparedness of Duane Davis remain unknown. It is crucial for water resource and climate enthusiasts to monitor and assess the risk management measures of this dam to ensure the safety of the surrounding community and environment.

As a part of the Rock Island District, Duane Davis falls under the jurisdiction of the USDA NRCS and has not been subject to state regulatory oversight. With David Loebsack as the designated Congressional representative, it is essential for stakeholders to work collaboratively to address any potential risks and implement necessary measures to mitigate them. With its unique design and purpose, Duane Davis serves as a significant water resource infrastructure in the region, requiring careful monitoring and maintenance to uphold its functionality and safety standards.
