Set in both the arid lands of Arizona and the political backdrop of Washington, D.C., iVision in the Deserti documents the life and career of longtime Arizona senator, Carl Hayden. One of the most powerful figures in the United States Congress, Hayden's public service career, centered on water and its distribution, is inseparable from the history of the West and the development of arid lands. pElected to the House of Representatives in 1911, Hayden began a fifty-seven-year career in the U.S. Congress, serving as a Democratic House Representative for fifteen years and then as a Senator from 1927 to 1969. pThe issues of the development of the Colorado River occupied the majority of Hayden's congressional work. The authorization of the Central Arizona Project CAP in 1968, at the end of the senator's long career, highlights all of Hayden's efforts concerning this lifestream of the Southwest, making possible the distribution of water to the growing urban areas of Phoenix and Tucson.
