Blue Canyon is a federally owned water supply dam located in Apache County, Arizona, near the city of Ft. Defiance. Built in 1984 by the Bureau of Indian Affairs, it serves as a crucial source of water for the surrounding area. The dam stands at a structural height of 142 feet and has a length of 380 feet, with a storage capacity of 1900 acre-feet.

Despite its importance, Blue Canyon poses a high hazard potential due to its location and design. The dam is classified as having a very high risk level, with limited information available on its current condition assessment. The last inspection was conducted in 2012, and emergency action plans are not readily available, raising concerns about the readiness and response capabilities in case of a dam failure.

With its controlled spillway and primary purpose of water supply, Blue Canyon is a critical infrastructure for managing water resources in the region. However, the lack of recent assessments and emergency preparedness highlights the need for continued monitoring and maintenance to ensure the safety and reliability of this essential dam for the community it serves.
