Elgo is a federal-owned irrigation structure located in San Carlos, Arizona, along the San Carlos River. Completed in 1979 by the Bureau of Indian Affairs, this earth dam stands at a structural height of 133 feet and spans a length of 1100 feet. With a normal storage capacity of 6000 acre-feet, Elgo serves the primary purpose of providing water for irrigation in the region.

Despite its vital role in supporting agricultural activities, Elgo poses a high hazard potential due to its age and lack of recent condition assessments. The dam is classified as having a very high risk level, emphasizing the importance of regular inspections and maintenance to ensure the safety of surrounding communities. While an Emergency Action Plan (EAP) was last revised in 2013, there is a need for updated preparedness measures to align with current guidelines and mitigate potential risks.

As water resource and climate enthusiasts, the data on Elgo highlights the critical intersection between infrastructure, water management, and risk assessment. The detailed information provided sheds light on the importance of proactive measures to safeguard dams like Elgo, ensuring sustainable water usage and mitigating the potential impact of natural disasters on local communities. It serves as a reminder of the ongoing challenges in managing water resources and the need for continuous monitoring and maintenance of crucial infrastructure in the face of changing climate conditions.
