Little Rock Creek Dam, Little Rock Creek, Littlerock, Los Angeles County, CA

Significance: When built the Littlerock Dam was the tallest reinforced concrete multiple arch dam in the world. For over fifty years it has provided water for the South Antelope Valley and contributed to the valley's economic development. /When constructed in 1922-24, the Little Rock Creek Dam was the second highest multiple arch dam in the world, second only to that built in Tirso, Italy, at the same time. The Little Rock Creek Dam was the highest reinforced concrete multiple arch dam of the period, with the Tirso Dam of masonry-reinforced concrete construction. Sited adjacent to the very active San Andreas faultline, the dam is a superlative example of the innovative and artistic design work of internationally-acknowledged engineer John S. Eastwood. The Little Rock Creek Dam has provided water for the South Antelope Valley for nearly 70 years. Little Rock Creek Dam was listed on the National Register of Historic Places in 1976.
