As construction got underway, the Reclamation Service established a lumber mill in the Sierra Ancha Mountains north of the Roosevelt Dam site. A local source for construction lumber was less expensive than hauling it from Mesa, 1904. (Reclamation photograph)
By 1907, construction of the Roosevelt Dam was well underway. (Reclamation photograph)
Flooding was a serious threat during Roosevelt Dam construction, 1908. (Reclamation photograph)

Canal maintenance was an on-going problem, and Government sheep were used to control weeds and grass along the canals, 1914. (Reclamation photograph)
In 1864, the U.S. Army established the Yuma Quartermaster Depot on the Arizona side of the Colorado River where a six-month supply of goods was kept at all times. This is the earliest and one of few photographs of the depot taken before 1871. (Reclamation photograph)

Sand hogs at work on the heading of the Colorado River Siphon tunnel underneath the Colorado River. A "sand hog" is a slang term for construction workers who work underground on a variety of construction projects. A bulkhead of sandbags was built at the end lower of the tunnel while excavation continue in the upper half of the tunnel. The sandbags prevented water from seeping in on the sand hogs while the arch was being drilled, 1912. (National Archives, Yuma Project Office)

Apache workers were known for their skill in building dry-laid stone walls. Without using mortar, they constructed many such retaining walls along the various roads they built. This fine example is on Fish Creek Hill on the Mesa to Roosevelt Road, known today as the Apache Trail, 1905. (Courtesy of Salt River Project)
Apache workers often brought their families to live with them. They lived in a segregated area and maintained their traditional lifestyle. Here an Apache woman brings firewood to her wickiup, a structure of bent poles covered with brush that is also covered with blankets, tarps, and hides. Note the use of large ceramic storage jars and metal pots and pans, 1911. (Reclamation photograph)

American Indians, primarily Apaches, constructed over 100 miles of roads to provide access for men, equipment, and supplies to the dam site, 1905. (Reclamation photograph)
