ABSTRACT
Arizona, New Mexico, and Texas are illustrated in Figure 1 along with the Colorado River Basin and the Rio Grande River Basin. As previously noted, each of these three states is somewhat unique in their histories of water development and their present day management of water. A portion of these states lie in North American Deserts, the Sonoran Desert, the Great Basin Desert, the Mojave Desert and the Chihuahuan Desert as shown in Figure 2. A brief outline of the development of water in these states is given along with descriptions of some major water projects and water problems in these states.
