Cooley is a Federal-owned recreational dam located in Navajo, Arizona, along the Corduroy Creek. Built in 1963 by the Bureau of Indian Affairs, this Earth-type dam stands at a structural height of 39 feet and has a length of 250 feet, providing a storage capacity of 175 acre-feet. Despite its primary purpose for recreation, Cooley is classified as having a high hazard potential, with a very high risk assessment rating of 1.

Managed by the Bureau of Indian Affairs, Cooley does not have state regulation or permitting, but undergoes inspections every 5 years. The dam's spillway type is controlled, and it is situated within the Los Angeles District jurisdiction. While the condition assessment is currently unavailable, the Emergency Action Plan was last revised in 2011, indicating a proactive approach to safety measures. For water resource and climate enthusiasts, Cooley presents an intriguing case study of a Federal-owned dam with high hazard potential and significant risk management considerations.
