Mill Pond, located in Navajo, Arizona, is a privately owned irrigation reservoir that was completed in 1996. With a dam height of 30 feet and a storage capacity of 4400 acre-feet, this earth dam serves the primary purpose of irrigation and also other purposes. The reservoir covers a surface area of 260 acres and has a drainage area of 3.7 square miles, with a maximum discharge capacity of 1140 cubic feet per second.

Managed by the Arizona Department of Water Resources and regulated by the state, Mill Pond has a low hazard potential and a moderate risk assessment rating. Despite not being currently rated for condition assessment, the dam undergoes inspections every 5 years to ensure its safety and integrity. The spillway, with a width of 10 feet, is uncontrolled, allowing for excess water to safely flow out of the reservoir during periods of high inflow.

Enthusiasts of water resources and climate will find Mill Pond to be a unique and essential component of the irrigation infrastructure in the area. Its strategic location in Zeniff, Arizona, and its role in supporting agricultural activities make it a vital resource for the community. With its moderate risk assessment and regular inspections, Mill Pond stands as a reliable and effective water management structure in the region.
