This young orange grove near Camelback Mountain is located on desert soil and receives water from the Arizona Canal. John Wesley Powell's idea to classify lands by their resources was an attempt to ensure that lands with good soil conditions were made available for cultivation. These lands offered a better chance for success by farmers. Land classification eventually became a requirement by the U.S. Reclamation Service (and later the Bureau of Reclamation) for new irrigation projects. (Reclamation photograph)
Flooding on the Salt River created havoc for farmers as well as the Santa Fe Railroad. Floods damaged head gates, washed away diversion dams, and silted-in canals. Scenes like this ultimately led to the request for Federal assistance to build a dam on the Salt. 1905. (U.S. Reclamation Service)
Several miles east of Phoenix, formerly cultivated land has returned to desert. A lateral, visible in the foreground, lies useless because of a lack of water. Droughts, floods, and erratic river flows would plague Salt River Valley farmers until a dam was built to tame the river and some formal organization formed to promote equitable water management, 1902.
