Christensen Dam, located in Dow City, Iowa, was completed in 1999 and stands at a height of 30 feet with a length of 306 feet. Managed by a private owner, the dam's primary purpose is to control Tr- Coon Creek's flow and provide a storage capacity of 41 acre-feet. The dam is classified as an Earth-type structure with a low hazard potential and moderate risk assessment rating.

The dam's design was overseen by the USDA NRCS, and it is regulated by the Iowa DNR, with state permitting, inspection, and enforcement in place. Despite being uncontrolled, the spillway width of the dam is 1 foot, and it covers a surface area of 2 acres within a drainage area of 0.08 square miles. The dam's condition is currently not rated, but it has not been modified since its completion and has not undergone a recent inspection.

For water resource and climate enthusiasts, Christensen Dam offers an intriguing case study in dam management and regulation. Its location in Crawford County, Iowa, showcases the importance of private ownership in water infrastructure and the collaboration between federal agencies like the USDA NRCS and state regulators like the Iowa DNR. With its moderate risk assessment and low hazard potential, the dam presents an opportunity for further study on risk management measures and emergency preparedness in the face of potential climate challenges.
