BASIC GROUND-WATER DATA OF THE WILLCOX BASIN, GRAHAM AND COCHISE COUNTIES, ARIWNA

By S. G, Brown, H. H. Schumann, L. R. Kister, and P. W. Johnson

Introduction

In July 1959 the U. S. Geological Survey in cooperation with the

State Land Department, Obed M. Lassen, Commissioner, began an investi­

gation of the geology and ground-water resourcea of the Willcox basin as a

part of the overall investigation of the ground-water resources of Arf:!:ona.

This report is a summary of the basic data collected as they relate to the

water resources of the area, Figure 1 is a map of Arizona showing the lo­

cation and extent of the area investigated.

The purpose of this report is to make avsilable basic ground-water

data that are useful in planning and studying water-resources development

and to supplement a report that will be published later,

The data were collected chiefly during the period 1945 to 19S0.

Most of the well data, logs, well diScharges, and reported drawdowns were

obtained from well-registration forms of the Arizona State Land Depart­

ment. Drill cuttings for laboratory analysis were obtained through the co­

operation of the drillers working in the area. Water-level measurements

have been made by the U, S, Geological Survey more or less regularly since

1946, but some water-level records extend back to 1942,

Acknowledgments

Well owners and operators in the area have been cooperative in fur­

nishing information. Much supplemental information Was obtained from

pump companies and well drillers operating inthe Wilkox area. Mr. Carmy

G. Page, CountyAgriclllturalAgent, Willcox, supplied estimates of irrigated

acreage that were especially useful in computing irrigation pumpage. Mr.

Samuel F. Turner, consulting engineer, Phoenix, Ariz., and the mayor and

council of the city of Willcox granted access to data gathered byMr. Turner

during an investigation made for the city. :Mr. Gene Anderson and Mr. S.

B. Evans of the consulting firm of Gene Anderson, civil engineers, Tucson,

Ariz., allowed the use of data collected by them during a water-supply in­

vestigation for a housing development near Ash Creek School. Mr. Leonard

C. Halpenny of the Water Development Corp. and Mr. W. B. Loving, man­

ager of the Arizona Electric Power Cooperative, allowed access to data

collected during an investigation for water to supply a thermoelectric plant

near Cochise.

Work in the Willcox basin was begun under the immedIate direction

of L. A. Heindl, former acting district geologist, and continued under P.

E. Dennis, present district geologist of the GroundWater Branch in Arizona.

Substantial contributions, including most of the basic-data collection, were

madebypersonnel or the Arizona district. Those deserving special mention

are E. K. Morse, C. S. English, T. W. O'Brien, R. L. Thompson, and J.

T. Hollander. N. B. Carmony aided in the chemical analyses of the water

samples, G. S. Smith, W. D. Potts, and F. H. Rascop drafted the illus­

trations'. Mrs. Ruth Blubaugh and Mrs. Carol Jenkins typed the tables and

manuscript,

Well-Numbering System

The well numbers used by the Geological Survey in Arl:wna are in

accordance with the Bureau of Land Management's system of land subdivi­

sion. The land survey in Arizona is based on the GUa and Salt RIVer base

Hne and meridian, which divide the State into four quadrants (fig. 2l. These

quadrants are designated counterclockwlee by the capital letters A, B, C,

and D. All land north and east of the point of origin is in A quadrant, that

north and weet in B quadrant, that south and west in C quadrant, and that

south and east in 0 quadrant. The first digit of a well number indicates the

township, the second the range, and the third the section in which the well

is situated. The lowercase letters a, b, c, and d, after the section number,

indicate the well location within the section. The first letter denotes a par­

ticular ISO-acre tract, the second the 40-acre tract, and the third the 10-

acre tract (fig. 2). These letters also are assigned in a counterclockwise

direction, beginning in the northeast quarter. If the location is known with­

in a IO-acre tract, three lowercase leiters are shown in the well number.

In the example shown. well number {D-4-5}19caa designates the well as

being in the NE-l/4NE-I/4SW-t/4 sec. 19, T. 4 S .• R. 5 E. Where there

is more than one well within a IO-acre tract, consecutive numbers beginning

with 1 are added as suffixes.

Use of Tables and Maps

Included in this report are Well tables, drillers' logs, chemical a­

nalyses, well-location maps, water-table maps. and hydrographs, which are

discussed separately in numerIcal order.

Table 1. --Most of the wells included in this table are those con­

sidered to be representatiVe. Not every well Is included, nor would includ­

ing data on every well add little more than bulk to the report. Some wells are

included!n table 1 because the depth to water has been measured regularly,

although other well data are meager or are not available. Table 1 is cross­

referenced with tables 2, 3, and 4 as explained below. Wells lisled in table

1 are located on figure 3.

Table 1 includes the well location number, the date the well was

completed to the depth shown, and the casing and perforation record, if avail­

able. The firsl water levels sho .... n are those reported by the owners or
