Littlerock Dam

Littlerock Dam is a concrete structure that spans Little Rock Creek and holds water for the surrounding region. The structure uses a multiple arch design to store water for agricultural and residential uses in the valley below.

The dam was constructed in 1924 by engineer John S. Eastwood and was at that time the tallest structure of its kind in the world. Its innovative multi-arch design represented a breakthrough in dam engineering techniques.

The dam supported regional agricultural development by providing water supply to South Antelope Valley farmers and residents for multiple generations.

The proximity to the San Andreas fault makes this location interesting for those fascinated by geology and engineering. Visitors should expect uneven terrain and limited parking when viewing the structure from accessible vantage points.

The structure was specifically engineered to withstand conditions in a seismically active zone next to the San Andreas fault. This technical challenge made it a notable example of earthquake-resistant design in dam construction.
