Mexican Tank, located in Yavapai, Arizona, serves as a private fish and wildlife pond with a primary purpose of providing habitat for aquatic life. Built in 1930, this earth dam structure stands at a height of 27 feet and spans 600 feet in length, holding a storage capacity of 61 acre-feet. Situated along Partridge Canyon and regulated by the Arizona Department of Water Resources, Mexican Tank boasts a surface area of 10 acres and drains an area of 4.6 square miles.

Despite its low hazard potential, Mexican Tank remains a vital resource for fire protection, livestock watering, and supporting small fish populations in the region. With a spillway width of 160 feet and uncontrolled spillway type, the tank has a moderate risk assessment rating. While the last inspection took place in 2011, the structure is deemed to be in good condition and not rated for any significant issues. As a key feature in the local ecosystem, Mexican Tank plays a crucial role in maintaining biodiversity and water availability in the arid landscape of Arizona.
