An Inventory and Classification of Surface Water Resources in Grand Canyon National Park, Arizona
Brown BT, Butterfield KA, Johnson RR, Moran MS. 1979. An Inventory and Classification of Surface Water Resources in Grand Canyon National Park, Arizona. Grand Canyon, AZ
Data were gathered on the location, history, permanence, and quality of surface water resources within a 1,881 square miles area in northern Arizona. The availability of surface water was found to be primarily related to geologic structure, aquifer mechanics, and annual precipitation. The Muav Limestone is the major geologic formation in which perennial springs arise, while locally other formations may yield smaller quantities of water. Ephemeral and intermittent water sources predominate in the region, with the few perennial streams (excepting the Colorado River) being related to large perennial spring systems on both the north and south sides of the Colorado River. A classification system for surface waters in the southwestern United States is presented.
