Hydrogeologic data for the Coconino Plateau and adjacent areas, Coconino and Yavapai counties, Arizona

Abstract

Data on geology, topography, hydrology, climate, land use, and vegetation were compiled between October 2000 and September 2001 and assembled into a database for use by local and regional waterresources managers and for future water-resource investigations. The hydrologic data include information on wells, springs, streamflow, water chemistry, and water use. Limitations of the data and additional data needs also were prepared. The roughly 5,000-square-mile Coconino Plateau contains a complex regional aquifer that has become increasingly important as a source of water supply for domestic, municipal, and in-stream uses owing to population growth and development. The flow characteristics of the regional aquifer are poorly understood because the aquifer is deeply buried, which limits exploratory drilling and testing, and because the geologic structure, which controls the occurrence and movement of ground water, is complex. The study area is about 10,300 square miles and, besides containing the entire Coconino Plateau, includes parts of adjacent areas where ground water from the Coconino Plateau discharges. Selected data are presented in tabular or graphical form. All data are available in electronic form. Land-Use, Vegetation, and Water-Use Data Land-use and vegetation data can be used to evaluate runoff and evapotranspiration components of water budgets used to characterize regional hydrology. Water-use data provide information on groundwater and surface-water withdrawals that also are components in the construction of water budgets.

“…When structural deformation was minimal or absent, other wells in the C aquifer had no response to climate or pumping during the study. Bills and Flynn (2002) compiled hydrologic and geophysical data for the entire Coconino Plateau and adjacent areas. Additional data for this area were collected and analyzed by Bills and others (2007) to develop a groundwater budget and conceptual model for the combined C and Redwall-Muav aquifers.…”

“…The Coconino aquifer is the sequence of rock units between the Moenkopi Formation and the lower Supai Formation (McGavock and others, 1986;others, 2000, 2007;Bills and Flynn, 2002). The primary water producing unit is the Coconino Sandstone; however, the overlying Kaibab and Toroweap Limestones and the underlying Schnebly Hill Formation and upper and middle Supai Formations of the Supai Group can be locally major water producing units (Leake and others, 2005).…”

Groundwater, surface-water, and water-chemistry data from C-aquifer monitoring program, northeastern Arizona, 2005-11

“…C-aquifer hydrogeology and water use have been described in a number of USGS and non-USGS reports (Darton, 1910;Gregory, 1916;Harrell and Eckel, 1939;Johnson, 1962;Cooley and others, 1969;Mann, 1976Mann, , 1979Mann, , 1983Appel and Bills, 1980;McGavock and others, 1986;Bills and Flynn, 2002;others, 2000, 2007). Hart and others (2002) compiled data on the C aquifer in the LCR Basin and parts of the Verde and Salt River Basins and produced a groundwater budget and a generalized hydrogeological characterization of the C aquifer.…”
