Mellot Dam, located in Elliott, Iowa, is a privately owned earth dam completed in 1961 for fire protection, stock, and small fish pond purposes. It stands at a height of 27 feet and spans 490 feet in length, with a storage capacity of 69 acre-feet. Situated on TR-COE Creek in Montgomery County, this dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement.

Despite its low hazard potential and moderate risk assessment, Mellot Dam has not been rated for its current condition. However, its location in a rural area with a small drainage area of 0.43 square miles suggests a relatively low risk of downstream flooding. The dam's uncontrolled spillway type and lack of outlet gates may pose challenges in managing water discharge during periods of heavy rainfall, but overall, Mellot Dam serves its primary purposes effectively for the surrounding community.

Owned by a private entity and designed by the USDA NRCS, Mellot Dam exemplifies a local effort to provide essential water resources for fire protection and agricultural activities. Its construction reflects a historical commitment to water management in Iowa, contributing to the conservation of natural resources and enhancing the resilience of the region's water infrastructure. As climate change impacts continue to affect water availability and quality, dams like Mellot play a crucial role in sustaining local ecosystems and supporting agricultural sustainability in the face of evolving environmental challenges.
