Generalized hydrogeology and ground-water budget for the C Aquifer, Little Colorado River Basin and parts of the Verde and Salt River Basins, Arizona and New Mexico
The C aquifer underlies the Little Colorado River Basin and parts of the Verde and Salt River Basins and is named for the primary water-bearing rock unit of the aquifer, the Coconino Sandstone. The areal extent of this aquifer is more than 27,000 square miles. More than 1,000 well and spring sites were identified in the U.S. Geological Survey database for the C aquifer in Arizona and New Mexico. T

Investigation of the geology and hydrology of the upper and middle Verde River watershed of central Arizona: A project of the Arizona Rural Watershed Initiative
The upper and middle Verde River watershed in west-central Arizona is an area rich in natural beauty and cultural history and is an increasingly popular destination for tourists, recreationists, and permanent residents seeking its temperate climate. The diverse terrain of the region includes broad desert valleys, upland plains, forested mountain ranges, narrow canyons, and riparian areas along per

Investigation of the geology and hydrology of the Coconino Plateau of northern Arizona: a project of the Arizona Rural Watershed Initiative
The water resources of the Coconino Plateau in northern Arizona are under increasing demand as a result of development. The population of this arid region continues to grow, and the number of visitors to the many national and state parks and monuments in the region has increased annually. The sustainability, protection, and maintenance of springs and seeps and associated riparian habitat on the Co

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

Daily and seasonal variability of pH, dissolved oxygen, temperature, and specific conductance in the Colorado River between the forebay of Glen Canyon Dam and Lees Ferry, northeastern Arizona, 1998-99
The productivity of the trout fishery in the tailwater reach of the Colorado River downstream from Glen Canyon Dam depends on the productivity of lower trophic levels. Photosynthesis and respiration are basic biological processes that control productivity and alter pH and oxygen concentration. During 1998?99, data were collected to aid in the documentation of short- and long-term trends in these b

Investigation of the geology and hydrology of the Mogollon Highlands of central Arizona: a project of the Arizona Rural Watershed Initiative
The Mogollon Highlands of east central Arizona is a region of forested plateau and mountains, deep, sheerwalled canyons, and desert valleys. Known for its scenic beauty and characterized by a generally mild climate, the area, though still sparsely populated, attracts an increasing number of tourists and summer residents. Furthermore, the permanent population is expected to nearly double over the n

Hydrogeology of the regional aquifer near Flagstaff, Arizona, 1994-97
Sandstones, siltstones, and limestones that are Pennsylvanian to Permian in age underlie the southern
part of the Colorado Plateau near Flagstaff, Arizona, and contain a complex regional aquifer that has
become increasingly important as a source of water for domestic, municipal, and recreational uses.
Ground-water flow in the regional aquifer is poorly understood in this area because (1) depth of

Hydrologic data, Colorado River and major tributaries, Glen Canyon Dam to Diamond Creek, Arizona, water years 1990-95
The U.S. Geological Survey collected hydrologic data at 12 continuous-record stations along the Colorado River and its major tributaries between Glen Canyon Dam and Diamond Creek. The data were collected from October 1989 through September 1995 as part of the Bureau of Reclamation's Glen Canyon Environmental Studies. The data include daily values for streamflow discharge, suspended-sediment discha
