Big Dalton Dam

Big Dalton Dam is a concrete gravity structure within the Los Angeles County flood control system that regulates water flow during heavy rainfall. The structure manages runoff and is part of a larger network of water management infrastructure serving the region.

The project emerged after the Los Angeles County Flood Control District's formation in 1915 following severe floods that caused widespread regional damage. The dam construction was part of early efforts by authorities to protect communities from future flooding events.

The facility represents California's early twentieth-century infrastructure development during a period of rapid population growth and urban expansion. It shows how communities worked to protect their settlements from natural hazards.

Visitors can observe the dam structure from designated viewing areas accessible through nearby roads. The best time to visit is typically during dry weather when access roads are in good condition.

The dam is part of an extensive protection network consisting of multiple major structures spread across a large area of the region. This network demonstrates the complexity of modern water management in a densely populated area.
