Summit Reservoir, located in San Francisco, California, is a critical offstream water supply infrastructure owned by the local government and regulated by the Department of Water Resources (DWR) for safety and enforcement. This Earth dam stands at 38.5 feet high with a hydraulic height of 37.25 feet, providing a storage capacity of 43 acre-feet. The reservoir serves as a primary water source for the city, ensuring water security for its residents.

Despite its vital role in water supply, Summit Reservoir poses a high hazard potential and has been assessed to be in fair condition as of July 2018. Regular inspections are conducted, with the last one taking place in July 2019, to ensure the dam's structural integrity and safety standards are upheld. While the reservoir meets regulatory guidelines, contingency plans such as an Emergency Action Plan (EAP) and risk management measures are yet to be fully documented and updated.

Enthusiasts interested in water resource management and climate resilience would find Summit Reservoir to be a crucial piece of infrastructure in San Francisco's water supply network. With its strategic location and role in ensuring water security, ongoing monitoring and maintenance efforts are essential to sustainably manage this critical water resource in the face of changing climate conditions.
