GROUND-WATER LEVELS IN WYOMING, 1975

by 

Wilbur C. Ballance and Pamela B. Freudenthai

ABSTRACT

Ground-water levels are measured periodically in a network of about 

260 observation wells in Wyoming to record changes in ground-water 

storage. The areas of water-level observation are mostly where ground 

water is used in large quantities for irrigation or municipal purposes. 

This report contains maps showing location of observation wells and 

water-level changes from 1975 to 1976. Well history, highest and lowest 

water levels, and hydrographs for most wells are also included in this 

report.

The program of ground-water observation is conducted by the U.S. 

Geological Survey in cooperation with the Wyoming State Engineer and the 

city of Cheyenne.

INTRODUCTION

Ground-water levels are measured periodically in a network of 

observation wells in Wyoming, principally in areas where ground water is 

used for irrigation or municipal purposes. The water levels are usually 

measured in January, February, or March. However, sometimes weather 

conditions prevent reaching some wells until April. The time selected 

for measuring is when recovery of water levels from pumping effects of 

the previous irrigation season is virtually complete. These water-level 

measurements indicate changes in ground-water storage when compared T Tith 

previous measurements.

Water levels measured in about 245 wells during the first 4 months 

of 1976 were compared with measurements made during the same period in 

1975 to give the net change in water levels for this period. These net 

changes along with depth to water in 1976 are shown in tables and on 

maps. Water levels were measured periodically in about 260 wells for a 

total of about 1,000 measurements in 1975. Twenty wells were equipped 

with water-stage recorders in 1975. Hydrographs of most wells in the 

observation-well network were made using periodic measurements and tl'e 

highest water levels recorded for the first and fifteenth day of eacl" 

month for those wells equipped with water-stage recorders.

Three previous reports of ground-water levels in Wyoming were 

compiled by the U.S. Geological Survey (Ringen, 1973; Ringen, 1974; 

Ballance and Freudenthai, 1975).
PRESENTATION OF DATA

The data in this report are presented alphabetically by counties 

(fig. 1). Records of observation wells for each county are listed in a 

table, preceded by a map of each county (figs. 2-21) showing the location 

of the wells, water-level change 1975-76, and the depth to water below 

land surface in 1976. Because of the large number of wells measured in 

the Cheyenne well field, only locations for selected wells are shown on 

the map of western Laramie County.

In addition to the annual measurements, selected wells are measured 

periodically, generally at 2- to 4-month intervals, in order to show 

seasonal changes in water levels caused by precipitation and pumping. 

Following the table of annual measurements for each county are hydrographs 

for most wells for the 10-year period 1966-1975, or for the period of 

record if less than 10 years.

All water-level measurements tabulated in this report are in feet 

below land-surface datum, unless otherwise indicated. A plus sign (4) 

is used to indicate water level above land-surface datum.

Well-Numbering System

The system of numbering wells in Wyoming is based on the common 

subdivision of public lands into sections. The 40th Parallel Base Line 

and the Sixth Principal Meridian are used as a reference for most of 

Wyoming. Land subdivisions in Wyoming referenced to that base line and 

meridian are north and west of the point of origin; therefore, north and 

west are not specified in the designation for well numbers. The well 

number, in addition to designating the well, locates its position to the 

nearest 10-acre [4.05-square hectometers (hm2 )] tract in the land network. 

The first segment of the number denotes the township north of the 40th 

Parallel Base Line; the second segment denotes the range west of the 

Sixth Principal Meridian; and the third segment denotes the section. 

The fourth segment of the number, consisting of one to three lower case 

letters, denotes the 160-acre (64.8-hm2 ), 40-acre (16.2-hm2 ), and 10-acre 

(4.05-hm2 ) tracts, respectively, in which the well is situated. For 

this purpose, the section is divided into four quarters, a, b, c, 

and d, reading in a counterclockwise direction, for the northeast, 

northwest, southwest, and southeast quarters, respectively. The first 

letter of the fourth segment gives the quarter section, which is a tract 

of 160 acres (64.8 hm2 ). Similarly, the quarter section is divided into 

four 40-acre (16.2-hm2 ) tracts lettered in the same manner and the 

second letter, if present, denotes the 40-acre (16.2-hm2 ) tract. Finally, 

the 40-acre tract is divided into four 10-acre (4.05-hm2 ) tracts, and 

the third letter, if present, denotes the 10-acre (4.05-hm2 ) tract, 

(fig. 2) in Crook County is in the SE%NW%NW% sec. 18, T. 53, R. 65. If 

there is more than one well in the 10-acre tract, a numeral is added 

after the fourth segment to show that it is one of several wells assigned 

a number in that 10-acre tract.

Observation wells in Fremont County on the Wind River Indian 

Reservation are similarly located; however, they are in a land subdivision that is referenced to the Wind River Base Line and Meridian, 

as used by Morris and others (1959). Wells within this system may be in 

the northeast, northwest, southwest, or southeast quadrants of this 

base-line and meridian net. Well numbers in this land net have the 

upper-case-letter prefixes A, B, C, or D to designate the northeast, 

northwest, southwest, or southeast quadrants, respectively.

Use of Metric Units

The International System (SI) of units is being adopted for use in 

reports prepared by the Geological Survey. To assist readers of this 

report in understanding and becoming accustomed to the new system, 

measurements used in describing the well-numbering system are reported 

in English units and, in parentheses, SI or metric units. The English 

units used in this report may be converted to metric (SI) units by use 

of the following factors:

Multiply English units by

acres 0.4047

feet .3048

To obtain metric (SI) units

square hectometers (hm2 ) 

meters (m)
