This water resource infrastructure is primarily used for irrigation and water supply purposes, with a dam height of 41 feet and a hydraulic height of 36 feet. Completed in 1965, the reservoir has a storage capacity of 94 acre-feet and covers a surface area of 9 acres, serving the surrounding area with water from Tr L Green Horn Creek.
Managed by the California Department of Water Resources and regulated for safety by the Safety of Dams agency, Loma Rica Airport has a high hazard potential but has been assessed as satisfactory in condition. Regular inspections are conducted, with the last assessment completed in September 2017. Despite its age, the facility meets state permitting and enforcement requirements, ensuring that it continues to provide vital water resources to the community. In the event of an emergency, an Emergency Action Plan is in place, last revised in January 2019.
With its strategic location and critical role in water supply management, Loma Rica Airport remains a key asset for the region. The dam's design and construction as an earth structure have stood the test of time, demonstrating the resilience and reliability of this essential infrastructure. As climate change impacts water resources, facilities like Loma Rica Airport will play an increasingly important role in ensuring sustainable and secure water supplies for the future.
