Llano del Rio was a commune (or "colony") located in what is now Llano, California, east of Palmdale in the Antelope Valley, Los Angeles County. The colony was devised by lawyer and socialist politician Job Harriman after he had failed his bid to become the mayor of Los Angeles in 1911. The colony's land was acquired in 1913 and it was formally launched on May 1, 1914.
The Llano del Rio Colony settled in the southern edge of the Mojave Desert along Highway 138 near what is now 165th Street East, in the alluvial plain that spread out to the north from the San Gabriel Mountains. The colony took advantage of water from Big Rock Creek, an intermittent stream that flowed from the San Gabriel Mountains. Several structures were constructed using local granite boulders and lumber, including a hotel, meeting house, and water storage tank. There was also a small open aqueduct made of granite cobbles and cement. The remnants of the built features are still visible at the site.
During 1918, the colony was abandoned. Llano del Rio turned out to be too far from other settlements to develop a sustaining economy, and the water supply from Big Rock Creek proved to be unreliable. Some of the settlers, approximately 60 families in all, relocated to form New Llano, Louisiana.[2]
