TULE LAKE SEGREGATION CENTER
Newell townsite
National Historic Landmark 2/17/2006
Tule Lake Segregation Center was the largest and longest-lived of the ten camps built by the War Relocation Authority (WRA) to house the nearly 120,000 Japanese Americans relocated from the West Coast during World War II, pursuant to Executive Order 9066. In 1943, the facility was converted to a maximum security segregation center for evacuees deemed by the WRA to be “disloyal.” The segregation center historically comprised 7,400 acres. The National Historic Landmark encompasses the original segregation center’s Stockade, the WRA Motor Pool, the Post Engineer’s Yard and Motor Pool, and a small part of the Military Police Compound. Reclamation is a part owner of the National Historic Landmark.

EARTH FIGURES OF CALIFORNIA-ARIZONA COLORADO RIVER BASIN
"Palo Verde Circles" (Reclamation property )
Vicinity of Palo Verde Dam
National Register Thematic Nomination
Included in this nomination are a series of large prehistoric, and possibly
historic, designs created in the dark desert surface or " varnish " bordering
the Colorado River in California and Arizona. The designs were almost
all made by removal of the surface layer of darkened rock to expose a
lighter subsurface of earth material. Because of their great size
or faintness, the figures, in many instances, are best seen from the air.
The Reclamation-owned feature, known as the Palo Verde Circles, consists
of three rings. The site may have served as a meeting place.

FOLSOM POWERHOUSE

National Register 10/02/1973
National Historic Landmark 5/29/1981
The Folsom Powerhouse site contains two buildings constructed to house
hydroelectric generating equipment. When completed in 1895, the
main powerhouse represented a major advance in the generation and transmission
of electricity. For the first time, high-voltage alternating current
could be transmitted over long distances. A secondary power plant,
owned by Reclamation, was installed below the main facility in 1897.
California Department of Parks and Recreation operates the site as a historic
park.
