Brief Description

The remote community of Chiriaco Summit lies adjacent to the Colorado River Aqueduct and Interstate 10, approximately halfway between Palm Desert and Blythe.

The community has provided a truck stop and other motorist services since 1933 and is the location of the General Patton Memorial Museum. Community founders provided food and sanitary services to laborers during construction of the Colorado River Aqueduct and originally relied on springs for water supply. In 1986, Metropolitan and Caltrans entered into an agreement for sale of water to benefit the traveling public near Chiriaco Summit. Caltrans subsequently entered into an agreement with the owners of the motorist services facility.

In 2002, Metropolitan entered into the existing water sale contract with Caltrans and Chiriaco, a county water district formed in 2000. Caltrans was willing to assist Chiriaco in obtaining water for services at Chiriaco Summit because of the location and service available to the traveling public.
