Located in Tuolumne, California, the Quartz dam is a crucial piece of infrastructure designed for water supply purposes, including flood risk reduction, irrigation, and water supply. Completed in 1978, this earth dam stands at a height of 104 feet with a hydraulic height of 100 feet, providing a storage capacity of 1500 acre-feet. The dam's primary purpose is to ensure a reliable water supply for the surrounding area, particularly during periods of drought or increased demand.

Managed by a public utility, the Quartz dam is regulated by the California Department of Water Resources (DWR) and falls under the jurisdiction of the Safety of Dams program. With a low hazard potential and a satisfactory condition assessment, the dam is regularly inspected to ensure its structural integrity and safety. The last inspection in February 2021 confirmed its satisfactory condition, highlighting the importance of ongoing monitoring and maintenance to prevent any potential risks or failures.

As climate change continues to impact water resources and weather patterns, the role of dams like Quartz in managing water supply and mitigating flood risks becomes increasingly significant. With a focus on sustainability and resilience, ensuring the proper maintenance and regulation of these essential structures is crucial for safeguarding water resources and infrastructure in the face of a changing climate.
