The political patterns of Western water policy are best explained as cooperation among the few, or "elites". The extent of elitism is demonstrated across four eras of Western water policy, the Foundation of Elites (1880s-1920s); the Emergence of Elites (1920s-1930s); the Golden Age of concrete (1930s-1960s); and the Era of Diminishing Returns (1970s- Present). The four phases test for elitism in a three step process. First, California and Arizona water politics serve as case studies to distinguish between elite and non-elite water interests. Second, the magnitude of elite control over Western water policy is tied to the "geopolitical" importance of the Colorado River. Over time Los Angeles' interests have come to dominate water policy in the Southwest. Third, change away from elitism to a more equitable political environment is explored. Alternatives include pluralism, liberalism, and idealism. These options offer insight on how change away from elite politics might effect Western water policy in the nineties.
