Donald Bills
Don joined the USGS Arizona Water Science Center in 1978 and is currently a Scientist Emeritus.
Donald Bills is a Scientist Emeritus with over 34 years of experience in basic data programs and projects studying the surface water, groundwater, and water chemistry of Northern Arizona and the western US. Don’s recent works include regional groundwater flow and contaminate hydrology (uranium and trace metals) of the Grand Canyon watershed, geohydrology of large regional flow systems in Northern Arizona, and groundwater-resources assessment and development support for Tribal Lands in Northern Arizona.
Don’s special interests are in large regional groundwater-flow systems and regional springs. Don has an interest in borehole and surface geophysics.
Professional Experience
In 2009, Don was appointed to a national team developing observation well and streamflow-gaging station abandonment guidelines for the American Reinvestment and Recovery Act.
In 2011, Don was selected as a team member for the Energy and Minerals Mission Area Strategic Science Planning Team.
Education and Certifications
BS, Physical Science, California State University-Chico, 1976.

Electrical resistance sensors record spring flow timing, Grand Canyon, Arizona
Springs along the south rim of the Grand Canyon, Arizona, are important ecological and cultural resources in Grand Canyon National Park and are discharge points for regional and local aquifers of the Coconino Plateau. This study evaluated the applicability of electrical resistance (ER) sensors for measuring diffuse, low-stage (

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 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

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

When the blue-green waters turn red: Historical flooding in Havasu Creek, Arizona
Havasu Creek, the second largest tributary of the Colorado River in Grand Canyon National Park, attracts numerous visitors each year owing to its spectacular scenery. Perennial streamflow seldom exceeds 2 cubic meters per second (m3/s), but supports important stands of riparian vegetation, forms unique travertine pools, and spills over spectacular waterfalls. Havasu Canyon is home to the Havasupai

Shallow subsurface temperatures and some estimates of heat flow from the Colorado Plateau of northeastern Arizona
Temperature data to depths of a few hundred meters were obtained from 29 wells in northeastern Arizona; 12 in the region surrounding the San Francisco Volcanic Field, 8 in the Black Mesa area, and 9 in the south-central Colorado Plateau which includes the White Mountains. Although there was evidence for local hydrologic disturbances in many temperature profiles, most wells provided an estimate of

Maps Showing Ground-Water Conditions in the San Francisco Peaks Area, Coconino County, Arizona - 1979
INTRODUCTION
The San Francisco Peaks area includes about 2,300 mi2, of which about 500 mi2 is in the Navajo Indian Reservation, in north-central Arizona. Ground-water development has been slight except for the public-supply wells for Flagstaff and domestic wells in Fort Valley, Pitman Valley, and the area west of Elden Mountain. The public water supply for Flagstaff is primarily from Upper Lake
