Lake Herman, located in Solano County, California, is a vital water resource managed by the local government for irrigation and water supply purposes. The dam, completed in 1905, stands at a height of 51 feet and has a storage capacity of 2,210 acre-feet. With a surface area of 110 acres, the lake serves as a key source of water for the surrounding area, drawing from Sulphur Springs Creek.

Despite its age, Lake Herman's dam is in satisfactory condition and is regularly inspected by state regulatory agencies to ensure its safety and functionality. The dam's high hazard potential necessitates a thorough emergency action plan, although specific details such as inundation maps and risk assessments are not yet available. The dam's proximity to Benecia and its role in water management highlight the critical importance of maintaining and monitoring this key infrastructure in the face of changing climate patterns and water resource demands.
