Banning Dam

Banning Dam is a gravity dam in California that stores and manages water for the region. The structure features a vertical upstream face and a stepped downstream design that helps control water flow.

Banning Dam was built between 1924 and 1926 as part of the Los Angeles Aqueduct system under William Mulholland's direction. The project marked an important development in California's water management infrastructure.

Engineers study Banning Dam's construction methods and safety protocols as a reference point for water infrastructure development in California.

The structure is well maintained through regular inspections and upkeep to ensure it functions properly. Access to the site may be limited, so check local visitor information before planning your visit.

The dam includes internal and foundation drainage systems designed to prevent water pressure from building up underneath and destabilizing the structure. These systems work quietly but are crucial for keeping the dam safe over the long term.
