Number 7 is a private earth dam located in Pima, Arizona, with a height of 189 feet and a length of 15,441 feet. The dam serves the primary purpose of storing tailings, with a maximum storage capacity of 306,000 acre-feet. Despite being privately owned and not regulated by the state, Number 7 poses a high hazard potential, indicating the potential for significant damage and loss in the event of a failure.

Managed by the Mine Safety and Health Administration, Number 7 has not undergone a recent condition assessment, leaving its current state unknown. With no Emergency Action Plan in place or updated emergency contacts, the dam lacks crucial preparedness measures for potential incidents. The absence of risk assessment and management measures further highlight the need for increased monitoring and maintenance to ensure the safety and integrity of the structure for surrounding communities and the environment.

For water resource and climate enthusiasts, Number 7 presents a significant case study in the importance of proper dam management and regulation. As a high hazard dam with unknown condition assessment and emergency preparedness, it underscores the potential risks associated with aging infrastructure and the critical need for proactive monitoring and maintenance to prevent catastrophic failures and protect water resources and ecosystems.
