Ninemile is a historically significant earth dam located on Nine Mile Creek in Gunnison, Utah. Built in 1900 for irrigation purposes, it stands at a structural height of 55 feet and has a hydraulic height of 46 feet. With a storage capacity of 4,300 acre-feet and a drainage area of 4 square miles, Ninemile plays a vital role in water resource management in the region.

Managed by the Utah Division of Water Rights, Ninemile is regulated, inspected, and enforced to ensure its safe operation. Despite being classified as having a high hazard potential, the dam is currently in fair condition, with the last inspection conducted in July 2020. The dam's emergency action plan status and risk assessment measures are yet to be determined, highlighting the importance of proactive risk management for this critical infrastructure.

Located within the jurisdiction of the Los Angeles District of the US Army Corps of Engineers, Ninemile serves as a reminder of the intersection between water resource management and climate resilience. As climate change continues to impact water availability and quality, the maintenance and upkeep of dams like Ninemile are essential for ensuring sustainable water use and mitigating potential risks to surrounding communities and ecosystems.
