Isu Dam, located in Ames, Iowa, along the Skunk River, was completed in 1958 for the primary purposes of fire protection, stock, and small fish pond. This earth dam, designed by USDA NRCS, stands at a height of 37 feet and stretches 460 feet in length, with a storage capacity of 170 acre-feet. Although it is classified as having a low hazard potential, the dam is regulated, permitted, inspected, and enforced by the Iowa DNR, ensuring its safe operation and maintenance.

With a moderate risk assessment rating, Isu Dam has not been rated for its condition assessment. Despite this, the dam's location in Story County holds significance for water resource and climate enthusiasts, as it plays a vital role in managing water resources and supporting local ecosystems. The dam's controlled release through an uncontrolled spillway helps mitigate flood risks and provides valuable water storage for agricultural and environmental purposes.

As a key structure in the Rock Island District, Isu Dam serves as a critical element in the region's water management infrastructure. Its historical significance, coupled with its ongoing role in protecting the local community and supporting diverse water uses, makes Isu Dam a fascinating subject for those interested in water resource management and climate resilience efforts in Iowa.
