Williams Dam, located in Los Gatos, California, is a gravity type dam built in 1895 with a height of 69 feet and a storage capacity of 160 acre-feet on the Los Gatos Creek. Managed by a Public Utility, the dam serves the primary purpose of water supply for the region. The dam is regulated by the California Department of Water Resources and is subject to regular inspections, with the last assessment in September 2020 showing satisfactory condition and low hazard potential.

Despite its age, Williams Dam continues to play a vital role in water resource management in Santa Clara County. With a drainage area of 5.7 square miles and a surface area of 3 acres, the dam contributes to the water supply needs of the surrounding area. In the event of an emergency, the dam is equipped with an Emergency Action Plan to ensure public safety and has designated emergency contacts to coordinate response efforts.

Located in a region susceptible to droughts and increasingly unpredictable weather patterns due to climate change, the maintenance and monitoring of Williams Dam are crucial for ensuring water security in the area. As a key infrastructure for water supply, the dam's continued operation and adherence to safety regulations are essential for mitigating risks and adapting to the challenges posed by a changing climate.
