Coffman Dam, located in Tama, Iowa, along the TR-Iowa River, was completed in 1965 by the USDA NRCS with a primary purpose of providing fire protection and serving as a stock or small fish pond. The earth dam stands at a height of 26 feet with a length of 523 feet, offering a storage capacity of 83 acre-feet. While the dam has a low hazard potential, it is classified as having a moderate risk level, indicating the need for ongoing monitoring and management measures.

Managed by a private owner, Coffman Dam is regulated by the Iowa DNR and falls under state jurisdiction for permitting, inspection, and enforcement. The dam is designed to withstand normal operational conditions, with an uncontrolled spillway type in place. Despite not being rated for its current condition, the dam's risk level suggests a need for continuous assessment and potentially the development of an emergency action plan to mitigate any potential risks associated with its operation.

With its location in a rural area and serving multiple purposes beyond flood control, Coffman Dam provides valuable water resource management support for the local community. As water resource and climate enthusiasts, attention to the dam's structural integrity, maintenance, and risk management measures can help ensure the continued safety and efficiency of this vital infrastructure.
