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 water-resource 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.
