Gerot Dam, located in Louisa County, Iowa, is a privately owned structure designed by USDA NRCS for the primary purpose of grade stabilization along the Tr- Iowa River. Completed in 1999, this earth dam stands at a height of 28 feet and stretches 210 feet in length, with a storage capacity of 22 acre-feet. Despite its low hazard potential and moderate risk assessment rating, the dam is currently not rated in terms of condition assessment, and no emergency action plan (EAP) has been prepared or updated.

Managed by the Natural Resources Conservation Service, Gerot Dam serves as a vital component in controlling the flow of water and protecting the surrounding area from potential flooding. Its uncontrolled spillway type and soil foundation ensure the stability of the structure, while its location in Columbus Junction contributes to the overall water resource management in the region. With a drainage area of 0.06 square miles and a surface area of 2 acres, this dam plays a crucial role in maintaining the ecological balance and water quality of the Iowa River.

Although Gerot Dam has not been subject to recent inspections or assessments, its presence as a grade stabilization structure underscores the importance of sustainable water resource management in the face of changing climate conditions. As a key component in the overall water infrastructure of Louisa County, this dam serves as a reminder of the critical role that such structures play in ensuring the safety and resilience of communities in the region.
