Aerial view of the Mark Wilmer pumping plant located near Lake Havasu, Arizona. It is one of fourteen pumping plants located along the 336-mile long delivery system, lifting water 3,000 feet. An additional pump/generating plant is located off the main aqueduct at New Waddell Dam. (Reclamation photo)

During construction of the Central Arizona Project, some areas required that the water be delivered via huge concrete pipe sections, known as siphons, that could travel beneath obstructions such as roads or riverbeds. The concrete pipe sections were cast and stored as close to their eventual placement as possible.
Pipe sections were then delivered to the excavated channel using this special delivery method, dubbed "The Pipemobile."

Other areas of the Central Arizona Project required tunneling through mountains or hills.
This unusual piece of equipment, known appropriately as a "mole", was used to tunnel through mountains.

Glen Canyon Dam by Norman Rockwell (1894-1978); Oil on canvas, 51" x 77"; Glen Canyon Dam, Colorado River Storage Project, northern Arizona. Glen Canyon Dam in northern Arizona is the primary feature of the Colorado River Storage Project. Water stored behind the 710-foot high dam is used to meet obligations to the states of the Lower Colorado River Basin as outlined in the Colorado River Compact. The water is used for irrigation, power generation, municipal and industrial uses, and fish and wildlife enhancements. In addition, the dam provides a high degree of flood control along the lower Colorado River.
Norman Rockwell at Glen Canyon Dam, Arizona. Norman Rockwell is arguably one of America's most recognized artists. Born in New York, he left high school to study at the National Academy of Design and the Art Students League of New York. The cover of The Saturday Evening Post was his forum for over forty years, producing more than 400 covers for the magazine. Rockwell described himself as a "people painter," and indeed, people, common people from all walks of life were the models for most of his works. Among the most prominent subjects of Rockwell's work were Presidents Eisenhower, Kennedy, and Johnson, and world leaders including Nasser of Egypt and Nehru of India. The Norman Rockwell Museum in Stockbridge, Massachusetts has preserved a large collection of Rockwell's works. Reclamation Photo.

Now there's no trouble from gophers or water weeds, no seepage, and much less evaporation since the water travels much faster. Arizona Farmer-Ranchman, September 1969.
R. Keith Higginson, Commissioner, Bureau of Reclamation, 1977 - 1981. In 1957, Higginson earned his Bachelor of Science degree in Civil Engineering from Utah State University. His career in water management began as an engineer for water rights in the Utah State Engineer's Office from 1958 to 1965. He left Utah to direct Idaho's Department of Water Resources from 1965 to 1977. After Higginson's confirmation as Commissioner in 1977, the Bureau of Reclamation changed its name to the Water and Power Resources Service (WPRS). Other controversies of his term included defending President Jimmy Carter's "hit list" of Western water projects and initiation of policy that eventually became the Reclamation Reform Act.
