Upland Basin, located in San Bernardino, California, is a local government-owned structure designed for flood risk reduction. This Earth-type dam, completed in 2008, stands at a height of 19.8 feet with a hydraulic height of 15.5 feet. With a storage capacity of 362 acre-feet and a surface area of 27.9 acres, Upland Basin plays a crucial role in mitigating flood hazards in the region.

Managed by the California Department of Water Resources (DWR) and regulated by the Safety of Dams agency, Upland Basin has been deemed to have a high hazard potential. However, its condition assessment as of September 2017 was reported as satisfactory. Regular inspections and a comprehensive Emergency Action Plan (EAP) are in place to ensure the safety and functionality of the dam. In the event of an emergency, the local government is prepared to respond effectively, as demonstrated by the last EAP revision in December 2020.

For water resource and climate enthusiasts, Upland Basin serves as a significant infrastructure for flood risk management in the region. Its strategic location and design make it a vital component in safeguarding communities from potential inundation events. With ongoing regulatory oversight and maintenance efforts, Upland Basin stands as a testament to proactive risk management in the face of changing environmental conditions.
