New Calaveras, also known as Calaveras Reservoir, is a crucial water resource infrastructure located in Sunol, California. Owned by the local government, this dam on Calaveras Creek serves as a primary water supply for the region. Completed in 2018, the earth dam stands at an impressive height of 210 feet, with a hydraulic height of 194.2 feet, providing a storage capacity of 96,850 acre-feet and covering a surface area of 1,435 acres.

The dam's high hazard potential is closely monitored through regular inspections and maintenance, with the latest assessment in October 2018 deeming its condition as satisfactory. In the event of an emergency, an Emergency Action Plan (EAP) is in place, last revised in December 2020. Despite its critical role in water supply, New Calaveras faces potential risks that necessitate ongoing risk assessment and management measures to ensure the safety and security of the surrounding communities.

With its strategic location in Alameda County and close proximity to Sacramento District, New Calaveras represents a key component of California's water infrastructure. From its impressive structural design to its significant storage capacity, this dam plays a vital role in water resource management and climate resilience efforts in the region, underscoring the importance of continued monitoring and maintenance to safeguard its integrity for the future.
