Mill Creek No 1 Dam, located in Incline Village, Nevada, is a vital infrastructure managed by the local government for flood risk reduction along Mill Creek-OS. The dam, primarily constructed of earth and stone materials, stands at a height of 23 feet with a hydraulic height of 19 feet, offering a storage capacity of 2.4 acre-feet. Despite its fair condition assessment, the dam is categorized as having a high hazard potential, prompting regular inspections and enforcement by the Nevada Department of Water Resources.

Although the dam has an uncontrolled spillway type and a maximum discharge of 5 cubic feet per second, it plays a critical role in mitigating flood risks in the Washoe County region. With a moderate risk assessment rating of 3, the dam is closely monitored for any potential hazards or structural issues. The emergency action plan, last revised in August 2021, ensures that the necessary measures are in place to protect downstream communities in case of a dam failure, highlighting the importance of proactive risk management in water resource and climate conservation efforts within the area.
