Van Hall Dam, located in Marion, Iowa, was completed in 1996 and serves multiple purposes including fire protection, stock, and small fish pond management. The dam, with a height of 40 feet and a length of 413 feet, holds a storage capacity of 69 acre-feet, with a normal storage level of 52 acre-feet. It is primarily owned and regulated by private entities, with oversight from the Iowa Department of Natural Resources.

The dam, designed by NRCS, is classified as an earth dam with a low hazard potential. The risk assessment for the dam is rated as moderate, indicating a need for ongoing monitoring and management measures. The spillway is uncontrolled, and the dam is inspected, permitted, and enforced by state agencies. The location of Van Hall Dam at the Red Rock Reservoir in Iowa makes it a crucial structure for water resource management in the area.

Despite its low hazard potential, the moderate risk assessment for Van Hall Dam highlights the importance of continued monitoring and maintenance to ensure the safety and functionality of the structure. As a key element for fire protection and water management in the region, the dam plays a vital role in preserving water resources and mitigating potential climate-related risks in the area. Enthusiasts of water resources and climate change will find Van Hall Dam to be a significant case study in sustainable infrastructure management and resilience planning.
