Maria, a private dam located in Tracy, California, stands as a crucial water resource structure for irrigation and water supply purposes. Completed in 2003, this earth dam reaches a height of 48 feet and has a storage capacity of 277 acre-feet. With a significant hazard potential but a satisfactory condition assessment, Maria is regulated by the California Department of Water Resources (DWR) and undergoes regular inspections to ensure safety and compliance.

Situated on an unnamed stream in San Joaquin County, Maria plays a vital role in water management within the region. Owned privately, this dam is subject to state jurisdiction and enforcement, with the primary purpose of supplying water for agricultural and domestic use. Despite its high hazard potential, the structure has been deemed satisfactory in its condition assessment, indicating a commitment to maintaining its integrity and safety for the surrounding community.

With its proximity to the San Francisco District of the US Army Corps of Engineers, Maria serves as a critical infrastructure contributing to the water supply and irrigation needs of the area. Despite the potential risks associated with its high hazard classification, the dam's state-regulated status, regular inspections, and satisfactory condition assessment underscore its importance in ensuring water security and resource management in the region.
