An Inventory of Surface Water Resources in Grand Canyon National Park, Arizona
Brown BT and Moran MS. 1979. An Inventory of Surface Water Resources in Grand Canyon National Park, Arizona
In the same folder with this report is an undated overlapping one of 12 pages, by the same authors plus K. A. Butterfield and R. R. Johnson. Data were gathered in the Grand Canyon region on the location, history, quality, and permanence of surface water resources in a 1,881 square mile study area. The availability of water was found to be closely related to geologic structure, seasonality, annual precipitation and other factors. Fifty-seven perennial water sources have been identified: 21 perennial streams and 36 perennial seeps or springs. The Muav Limestone is the major geologic formation in which perennial seeps and springs arise, although other formations may be of local importance. A preliminary classification scheme for surface water sources in the Southwest is included. Appendices, glossary, very extensive bibliography
