Hernandez Reservoir, located in San Benito, California, is a crucial water supply source for the region. Owned by the local government, the dam was completed in 1962 and stands at a height of 124 feet, with a storage capacity of 18,000 acre-feet. The reservoir serves multiple purposes including irrigation, recreation, and water supply, drawing water from the San Benito River.

Maintained and regulated by the California Department of Water Resources, Hernandez Reservoir has a high hazard potential but is currently assessed as being in satisfactory condition. Regular inspections are conducted, with the last assessment in September 2017, and emergency preparedness plans are in place. The dam's location in a high-risk area underscores the importance of proper management and maintenance to ensure the safety and sustainability of the water resource for the surrounding community.

With its impressive hydraulic height of 105.5 feet and a surface area of 590 acres, Hernandez Reservoir is a significant feature in the local landscape. The dam plays a critical role in managing water resources, particularly in times of drought or increased demand. As climate change continues to impact water availability and quality, the importance of maintaining and monitoring reservoirs like Hernandez becomes even more pronounced for safeguarding the region's water supply and resilience to future challenges.
