Lauro, located in Santa Barbara, California, is a federal-owned Earth dam completed in 1951 with a primary purpose of water supply. Standing at a height of 137 feet and stretching 540 feet in length, it holds a maximum storage capacity of 855 acre-feet and covers a surface area of 26 acres. The dam's hydraulic height is 102 feet, with an uncontrolled spillway width of 3 feet, and a maximum discharge rate of 86 cubic feet per second.

Despite being marked as having a high hazard potential, Lauro has a moderate risk assessment rating. The dam underwent modifications in 2006 to enhance its seismic resilience. The Bureau of Reclamation oversees the operations, inspections, and regulatory aspects of the dam. It is situated along Diablo Creek and is managed by the Los Angeles District. With its critical role in water supply, Lauro represents a significant infrastructure asset in the region.

Ensuring the safety and maintenance of Lauro is essential for water resource management in the area. Although its condition assessment is currently not available, regular inspections and emergency preparedness measures are in place. The presence of reliable agencies like the Bureau of Reclamation underscores the commitment to safeguarding this vital water supply structure. As climate change impacts water resources, the resilience of dams like Lauro becomes increasingly crucial in securing water availability for communities in California.
