Explorations for Water Supplies on the Public Domain, I960

By Wm. S. Eisenlohr, Jr., and others

ABSTRACT

In making reconnaissancesfor water supplies on the public 

domain as part of the Soil and Moisture Conservation Program of the Department of the Interior, the Geological Survey obtains information on the availability of water that is 

useful for other purposes or in other areas. This report contains the information thus collected during the calendar year 

1960 in 46 areas scattered throughout 8 Western States. 

The accompanying tables list the sites of wells investigated, existing wells, springs, and wells drilled in 1960 as 

a result of investigations in that or previous years.

INTRODUCTION

This report summarizes the explorations 

for water, for use by stock grazing on the 

public domain,that were made in eight Western States (fig. 1) in 1960 as part of the Soil 

and Moisture Conservation Program of the 

Department of the Interior. Explorations 

made in previous years as part of this program are being summarized by areas for 

publication as water-supply papers.

The investigations on which this report is 

based were made for other bureaus of the 

Department of the Interior. They were concerned with finding water within a specified 

area and resulted in detailed recommendations on how to develop the needed water 

supply. The recommendations made are beyond the scope of this report, but some information of general interest on the availability of water was usually obtained in each 

investigation. The purpose of this report is 

to present the useful information obtained 

during the calendar year 1960.

The reconnaissances for water supplies 

rarely covered more than a few days in any 

area. Thus the geologic information given is 

usually very general and should be used with 

caution when inferring conditions at any distance from the site being described. The

places where water has already been found is 

important information when looking for new 

sources of water. For this reason, known 

sources of water, such as wells and springs, 

are listed for the areas investigated. Almost 

equally important are known failures to find 

water, if adequate information about the venture is available. In the tables of well and 

spring locations for each State, arranged by 

grazing district, are given in order: the sites 

investigated, existing wells, known springs, 

and finally wells drilled in 1960 as part of 

the Soil and Moisture Conservation Program. 

This information is presented as a guide to 

others faced with the problem of obtaining 

water supplies in these parts of the arid 

West.

The report was prepared by Wm.S. Eisenlohr, Jr., who supervised the writing of the 

contributions by the authors named.

SOIL AND MOISTURE CONSERVATION PROGRAM

By K. R. MELIN

Under the Soil and Moisture Conservation 

Program of the Department of the Interior, 

the Geological Survey conducts investigations 

and research to provide basic information 

needed in all facets of conservation of lands 

administered by the Department. The conservation program, in abroad sense, includes 

the protection of the land to achieve optimum 

production of forage as well as to retard 

downstream damage resulting from floods, 

such as channel cutting or deposition of sediment eroded from upland areas.

For the most part, the lands considered in 

this report are arid or semiarid, and the 

vegetation they bear is generally sparse. 

Nevertheless, despite their relatively low 

unit forage production, the lands traditionally
EXPLORATIONS FOR WATER SUPPLIES ON THE PUBLIC DOMAIN, 1960

have been used for grazing, and because of 

the great extent of lands involved, this use 

has formed and continues to form an impor^ 

tant part of the economy of several Western 

States.

Owing to the sparse cover of vegetation as 

well as to the inherent erodibility of the soils 

in many areas, grazing must be managed 

carefully to prevent permanent deterioration 

of the forage, as well as to prevent erosion, 

which will occur when concentrations of livestock are such that vegetation is depleted, 

soil is compacted, and stock-trails become 

intrenched. A very important aid to management is proper spacing of water supplies. 

The required spacing differs from one area 

to another depending upon distribution of forage and character of terrain. Economic fac - 

tors, such as the cost of water development 

in relation to the forage crop, must also be 

considered by the land-administration agencies.

In many localities water supplies about 2 

miles apart are desirable, but in others wider 

spacing generally will suffice. On the other 

hand, in areas where forage production is increased by mechanical treatments of the 

land, even closer spacing of water supplies 

may be advantageous. Generally, however, 

these objectives in range-water development 

have been achieved on only a relatively small 

part of the lands of the Department of the 

Interior. Consequently, the program of stockwater development is expected to continue together with installation of other conservation 

practices. To furnish basic information necessary for such development, additional investigations will be made and reports pre - 

pared by the Geological Survey.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 1

The Bureau of Land Management Grazing 

District 1 comprises parts of Mohave and 

Coconino Counties. Explorations for water in 

1960 were made in the Virgin Mountains area 

(1, fig. 1) where three well sites were selected. Recommendations for stock-water 

sources were based on field examinations by 

the author.

Well sites 1 3 (table 1) were examined in 

the area east and southeast of the Virgin 

Mountains in October.

Site 1 is adjacent to Tom and Cull Wash, an 

ephemeral stream that flows in a channel 

underlain to considerable depth by unconsolidated alluvium. Runoff from the drainage 

basin upstream from the site should provide 

adequate recharge to maintain perennial underflow in the alluvium of the wash. The 

estimated depth to water is based on the inferred thickness of alluvium at the site.

Site 2 is near Cedar Wash in the outcrop 

area of the Shinarump Member of the Chinle 

Formation of Late Triassic age. In this area 

the Shinarump Member is largely sandstone 

with some lenses of conglomerate. Records 

of test holes drilled previously in this immediate area show that water can be found in 

these rocks at a depth of about 40 feet.

The terrain at site 3 is similar to that at 

Jacobs Well (El, table 1), which is about 9 

miles north of site 3, and obtains water from 

unconsolidated sediments deposited in Grand 

Wash trough at the southeast end of the Virgin 

Mountains; A second well (E2, table 1) about 

4 miles southeast of the site also obtains 

water from the alluvial fill in Grand Wash 

trough. The estimated depth to water at site 

3 is based on the depth to water at these wells 

with appropriate compensations for differences in elevation and probable differences 

in the configuration of the bedrock floor of 

Grand Wash trough.

Water in this area is reported to be of good 

quality for both stock and domestic use.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 2

Bureau of Land Management Grazing Dis - 

trict 2 comprises parts of Mohave and 

Yavapai Counties. Explorations for water in 

1960 were made in 2 areas where 10 well sites 

were located. Recommendations for stockwater sources were based on field examinations by the author.

Yucca area

An area east of Yucca (2, fig. 1) on the 

west slopes of the Hualpai and McCracken
ARIZONA

Mountains was examined in January to determine the prospects of developing stock-water 

supplies at nine well sites selected by the 

Bureau of Land Management. Both mountain 

ranges are composed largely of granite and 

granitic gneiss of low permeability. Small 

springs or seeps issue locally where the bedrock is sufficiently fractured to intercept 

surface flows, but predictable occurrences of 

ground water are limited mainly to local underflow in the coarse, unconsolidated alluvial 

deposits that underlie the larger washes. 

Several comparatively shallow wells have 

been dug or drilled into these channel deposits 

to tap the ground water, but commonly these 

wells are seasonal rather than perennial 

sources of water.

All but one of the proposed sites (5-12, table 

1) are in washes where wells or springs, 

either upstream or downstream from the 

sites, attest to the occurrence of underflow in 

the channel alluvium. The other site (4, table 

1) is underlain by impermeable granitic bedrock, and therefore, drilling was not recommended.

Water in this area is reported to be of suitable quality for both stock and domestic use.

Kingman area

In June, well site 13 (table 1) near the Bureau 

of Land Management's warehouse compound 

about 2 miles southwest of Kingman (3, fig. 1) 

was examined to determine if water could be 

obtained that would be suitable for both ware - 

house and livestock use.

An outcrop of granitic rock immediately 

south of the compound indicates impermeable 

bedrock at shallow depth beneath the warehouse area. About a half mile north and 

northwest of the compound, volcanic rocks of 

both rhyolitic and basaltic composition crop 

out to form steep cliffs. The area between 

these cliffs and the outcrop of granitic rock 

is covered by alluvium and volcanic debris of 

undetermined thickness below which may lie 

either granitic or volcanic rocks. As wells in 

the vicinity of Kingman (E9 Ell, table 1) 

prove that water suitable in quality for the 

intended use can be obtained from the volcanic 

rocks, the most promising location for a well 

appears to be in the proximity of the outcrop 

of volcanic rocks.

BUREAU OF LAND MANAGEMENT GRAZING t 1SFRICT 3

The Bureau of Land Management Grazing 

District 3 comprises parts of Maricopa, 

Yuma, Pima, Final, and Yavapai Counties. 

Explorations for water in 1960 were made in 

two areas where three well sites were located. 

Recommendations for stock-water sources 

were based on field examinations by the author.

Wickenburg area

Well sites 14 15 (table 1) were examined 

in the vicinity of Wickenburg (4, fig. 1) in 

September.

The geologic and topographic settings of 

the two sites, No. 14 in the Vulture Mountains 

about 10 miles southwest of Wickenburg, and 

No. 15 immediately west of a basalt hill 

known locally as Funeral Mountain about 10 

miles south of Wickenburg, are similar. Both 

sites are underlain by alluvium in unnamed 

washes whose drainage areas are considered 

to be large enough to supply underflow beneath the sites throughout the greater part of 

the year. The estimated depths to water of 

suitable quality are based on the inferred 

thickness of alluvium at the sites.

Table Top Mountain area

A broad alluvial fan deposit that extends 

southwestward from Table Top Mountain into 

Vekol Valley (5, fig. 1) was examined in 

September to determine the occurrence of 

ground water. Three basalt hills protrude 

from the deposit near the head of the fan. The 

alinement of these bedrock outcrops in a 

northwest direction suggests local faulting as 

the probable cause of the present bedrock relief. If a well is drilled southwest of the basalt hills over what is inferred to be the 

downdropped block, the well should not reach 

bedrock above the level of the local water 

table as indicated by the static water level in 

a well (E12, table 1) near Vekol Wash. Consequently, there can be little doubt of finding 

water in this part of the fan. If, however, a 

well is drilled northeast of the basalt hills 

near the head of the fan, it may reach bedrock 

at shallow depth. Water may be found at the 

contact of the alluvium and bedrock or in the 

volcanic rocks that are believed to underlie 

this part of the fan, but there is some risk of 

obtaining a dry hole.

CALIFORNIA

Owing to the favorable conditions of recharge at the upper part of the fan and the 

large size of the recharge area, prospects of 

finding water of suitable' quality for stock 

use are generally favorable anywhere on the 

fan deposit. Therefore, a specific well site 

was not selected.

CALIFORNIA

By C T. SNYDER

BUREAU OF LAND MANAGEMENT BAKERSFIELD 

GRAZING DISTRICT

Bakersfield Grazing District extends from 

San Bernardino County on the south to Mono 

County on the north and includes intervening 

counties in southern and eastern California. 

Explorations for water in 1960 were made in 

four areas where one spring and three well 

sites were examined. Recommendations for 

the development of stock water in these areas 

were based on fieldwork by the author and a 

report by Gilbert (1941).

Ivanpah Valley

Ivanpah Valley (1, fig. 1) was visited in 

mid-February. Well site 1 (table 2) was selected for drilling on the alluvial fan at the 

head of an unnamed tributary to Ivanpah Valley. This site, centrally located on the alluvial fan, was recommended for drilling to 

explore the alluvium for ground water that 

may be moving westward from the slopes of 

the New York Mountains toward Ivanpah Valley. No wells have been drilled into this alluvial fan, but wells drilled into similar fans 

elsewhere are usually successful. Water has 

also been found in the valley fill of Ivanpah 

Valley.

Old Dad Mountain area

The investigation in Old Dad Mountain area 

was made to determine the feasibility of developing a potential spring (SI, table 2) along 

an unnamed dry wash east of Old Dad Mountain (2, fig. 1). This area is called Burro 

Holes because wild burros dig into the sand 

for water that is moving as underflow through 

the alluvium about 2 feet below the surface. 

One such hole, still containing water, was 

found during the examination. A well drilled 

into the alluvium of the stream channel also 

contained water, but a well drilled into the 

bedrock on the south bank of the wash was

dry despite the fact that the wells are only a 

few yards apart. It was concluded that the 

underflow in the wash could be developed as 

a spring for stock water.

Piute Valley

In Piute Valley a site (2, table 2) was selected for exploratory drilling on the alluvial 

fan of an unnamed wash that flows eastward 

from the Piute Range to Piute Wash (3, fig. 1). 

The alluvial fan is fairly small and overlies 

east ward-dipping beds of basalt and bedded 

tuff of Tertiary age, but is in the area where 

water is needed near the foot of the mountains. The Piute Mountains west of the site 

are an uplifted fault block of eastward-dipping 

volcanic and pyroclastic rocks. Water may 

occur in the alluvial fan or in permeable 

parts of the underlying beds. No wells or 

springs are known to occur nearby, but the 

material in the alluvial fans and the underlying beds are potentially water bearing. As 

no other sources of water are available, exploratory drilling here seems to be justified.

Mono Lake area

The Mono Lake area (4, fig. 1) was visited 

in June, and well site 3 (table 2) was selected 

near the head of an alluvium-filled basin in 

the Cowtrack Mountains about Smiles southeast of Mono Lake. The geology of the area 

has been mapped by Gilbert (1941). The only 

place where it appears that a successful well 

could be drilled is in a basin that has been 

formed by erosion and faulting of the Tertiary and Quaternary volcanic rocks of the 

surrounding mountains. The rocks exposed 

there are dense and appear to be non water 

bearing so that the best chance for obtaining 

water would be the alluvium. No wells or 

springs have been reported in the area nearby. The alluvium appears to be sufficiently 

permeable to permit rapid infiltration of 

precipitation, as there are no signs of an alluvial fan nor of dry stream channels in the 

basin. There is a large risk, however, that 

no water can be obtained at this site.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 8

The Bureau of Land Management Grazing 

District 8 comprises parts of Saguache, Rio 

Grande, Conejos, and Alamosa Counties. Explorations for water in 1960 were made in 

northwestern San Luis Valley (l,fig. 1) where 

two well sites (Dl, D2,table 3) were located. 

Wells were drilled at these sites, but drilling 

was stopped at Dl before the estimated depth 

to water was reached. Recommendations for 

stock-water sources were based on field examinations by the author and a report by 

Powell (1958).

The area lies on each side of U.S. Highway 

285 from 5 miles east of Saguache to 7 miles 

north of Villagrove. The western boundary 

is the bedrock hills that rise abruptly from 

the gently sloping alluvial valley fill, and the 

eastern boundary is the extent of public 

grazing land east of Highway 285, generally 

about 2 to 4 miles.

The north end of the San Luis Valley has 

been filled to a depth of several hundred feet 

with silt, sand, gravel, and boulders derived 

from the surrounding mountains and transported and deposited by streams flowing into

the valley. This material, although poorly 

sorted and in some zones weakly cemented 

with calcium carbonate, is moderately permeable, and wells drilled below the level of 

the water table in the valley obtain adequate 

amounts of water for stock and domestic use. 

Many irrigation wells of high yield have been 

developed in this material in the central part 

of the valley.

The ground-water reservoir is recharged 

by perennial streams such as San Luis and 

Kerber Creeks, and by numerous small ephemeral streams. Its surface is probably 

parallel to the valley floor as in the central 

part of the valley (Powell, 1958). Wells 

drilled on alluvial fans at the mouths of ephemeral streams may obtain water at elevations somewhat above the regional water 

table.

Wells El and E2 (table 3) drilled into fractured igneous rock and volcanic ash beds, 

indicate that the zone of saturation extends 

from the valley fill into the surrounding bedrock.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 2

By M.C VAN LEWEN

The Bureau of Land Management Grazing 

District 2 comprises all of Garfield, McCone, 

and Dawson Counties and parts of Rosebud, 

Custer, and Prairie Counties. Explorations 

for water in 1960 were made in 3 areas (2 4, 

fig. 1) where 11 well sites were located. Information is given on one well drilled as a 

result of recommendations made in 1960. 

Recommendations for stock-water sources 

were based on field examinations by C. E. 

Sloan and the author and on reports by Perry 

(1934, 1935), Dobbin and Erdman (1955), and 

Collier and Knechtel (1939).

Areas near Van Norman, Garfield County 

(1 3, table 4), near Weldon, McCone County 

(4, D2, table 4), and between Rock Springs and 

DeGrand, Prairie and Custer Counties (5 9, 

E6, table 4) were examined to select sites for 

wells. Although these areas are widely separated geographically, all are underlain by

the Fort Union Formation of Paleocene age, 

and thus ground water occurs under similar 

conditions.

In eastern Montana the Fort Union Formation consists, from the base upward, of the 

Tullock, Lebo Shale, and Tongue River Members.

The Tullock Member averages about 250 

feet in thickness and is predominantly dark 

clay shale, with lesser amounts of sandy 

shale and crossbedded sandstone. A few thin 

coal beds occur in the member. The Tullock 

contains enough permeable sandstone that a 

well drilled to a moderate depth has an excellent chance of obtaining adequate water 

suitable for stock use.

The Lebo Shale Member, which consists of 

about 300 feet of very dark clay shale and 

carbonaceous shale, contains some lenses 

and pockets of gray to buff crossbedded sandstone, but because these lenses are randomly 

distributed and make up only a small part of 

the total thickness of the Lebo Shale Member, 

there is some risk that a well drilled into
8 EXPLORATIONS FOR WATER SUPPLIES ON THE PUBLIC DOMAIN, 1960

this member will not obtain water. However, 

most wells drilled into the Lebo Shale Member in the areas under consideration have 

been successful.

The Tongue River Member consists of intercalated beds of dark-gray to light-yellow 

shale, sandy shale, and sandstone. It is a 

very reliable aquifer that in this part of 

Montana it ranges in thickness from about 

700 feet near Weldon (Collier and Knechtel, 

1939) to about 1,200 feet near Mildred (Perry, 

1935). However, because sandstones of this 

member grade laterally into sandy shale and 

shale, commonly in a short distance, it is 

difficult to predict closely the depth to water.

In each of the areas examined, water in the 

Fort Union Formation is under artesian pressure, and a rise of water in a drilled well, 

often a substantial part of the total depth, 

may be expected. Water obtained from the 

Tongue River Member generally contains less 

dissolved solids than does water from either 

the Tullock or Lebo Shale Member. So far 

as is known all water produced by wells tapping the Fort Union Formation is suitable for 

stock use.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 3

By M. C. VAN LEWEN

The Bureau of Land Management Grazing 

District 3 comprises all of Fallon and Carter 

Counties and parts of Prairie, Custer, and 

Powder River Counties. Explorations for 

water in 1960 were made in the Mildred area 

(5, fig. 1) where six well sites (10 15, table 4) 

were examined. Recommendations for stockwater sources were based on field examinations by C. E. Sloan and the author and reports by Perry (1935) and Dobbin and Larsen 

(1936).

The six well sites are grouped around the 

community of Mildred. All but the Severson 

site (15) are immediately underlain by gently 

folded beds of the Fort Union Formation of 

Paleocene age whose water-bearing characteristics are discussed under Grazing District 2.

The Severson site is near the crest of the 

Cedar Creek anticline and is underlain by 

more than 1,000 feet of the Pierre Shale of 

Late Cretaceous age, which in this area does

not yield adequate amounts of water suitable 

for stock use. In general, the prospects are 

unfavorable for the development of stock water from drilled wells near the crest of Cedar 

Creek anticline, which extends from Baker to 

Glendive. Water supplies may be developed, 

however, on the flanks of the anticline from 

wells drilled into sandstones in the Fox Hills 

and Hell Creek Formations both of Late Cretaceous age.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 4

By M J. KING

The Bureau of Land Management Grazing 

District 4 occupies part of Carbon County. 

Explorations for water in 1960 were made in 

3 areas where 10 well sites were examined. 

Information was obtained on three wells (D3 

D5, table 4) that were drilled as a result of 

recommendations made in and before 1960. 

Recommendations for stock-water sources 

were based on field examinations and study 

of the "Geologic Map of Montana" (Rose, 

Andrews, and Witkind, 1955) by the author.

Belfry area

Two well sites were selected in the moderately dissected upland area southwest of 

Belfry (6, fig. 1). Both sites are in ephemeral-stream valleys that are incised in interbedded sandstone and shale of the Fort Union 

Formation. The stream valleys commonly 

are sinuous, following neither the dip nor the 

strike of the beds. Consequently, sandstone 

beds that underlie dip slopes in one valley 

reach may be truncated and drained at some 

downstream point where the valley is incised 

across the dipping beds.

Except near the drainage divides where the 

slopes are steep and the opportunity for recharge to potential aquifers is limited, wells 

should yield suitable supplies of water for 

stock use. The depth to water may be expected to range considerably from one part 

of the area to another depending on the local 

stratigraphy and the balance between groundwater recharge and drainage as determined 

by the topography. At site 16 (table 4) the 

beds dip in the opposite direction from the 

land surface. Sandstone beds underlying the 

site should not be drained below the level 

where they crop out in the channel downstream from the site. This corresponds to a
MONTANA

drilling depth of about 75 feet. Site 17 (table 

4), however, is on a dissected dip-slope surface that, when traced southeastward along 

the strike of the beds, ends abruptly against 

the valley of the Clarks Fork Yellowstone 

River. Very likely, therefore, permeable 

beds underlying the site are drained to about 

the river level, which corresponds to a drilling depth of 220 feet.

Elk Basin area

Four well locations selected by the Bureau 

of Land Management were examined in October to determine the prospects of finding 

water. The locations under consideration (7, 

fig. 1) are on the northeast flank of Elk Basin 

anticline where most streams flow in strike 

valleys cut in shale one side steep, the other 

a dip-slope surface generally underlain by 

sandstone. Thus potential aquifers in the 

form of sandstone beds of Mesozoic and Tertiary age can be reached at comparatively 

shallow depths in most of the strike valleys. 

The drilling program to date shows the average depth to water on the valley floors to be 

less than 150 feet. The depth to water increases with increasing distance up the valley sides and very likely is excessive near 

the drainage divides. Yields of existing wells 

seldom exceed 20 gpm, and no wells yield 

water that is not suitable for stock use.

Sites 18 20 (table 4) are in strike valleys 

underlain by potential aquifers so that prospects of completing stock-water wells at 

these locations are believed to be good to excellent. Site 21 (table 4), however, is on the 

high surface of Polecat Bench about 2 miles 

southeast of the point where the thick sandstone bed that underlies the site crops out in 

the bottom of Hunter Creek canyon. The absence of a spring in the canyon at the outcrop 

indicates that the inferred aquifer may be 

drained in the vicinity of the site. Therefore, 

there is some risk of obtaining a dry hole.

Pry or Mountain area

To determine the prospects of finding water 

in the proximity of three locations (22, 23, 25, 

table 4) selected by the Bureau of Land Management, an examination was made of the 

foothills area along the south and west sides 

of Big Pryor Mountain (8, fig. 1).

Near site 23 (table 4) the beds have been 

truncated by an old, erosional surface into

which canyons are again becoming deeply incised. As the dip of the beds is in the same 

direction, but at a greater angle than the slope 

of the land surface,progressively older formations are exposed toward the mountain 

front. Consequently, runoff from the mountain crosses the outcrop areas of formations 

underlying the site, thus affording an excellent opportunity for recharge to beds capable 

of transmitting water. Despite the opportunity for recharge, however, drilling was not 

recommended as the site is underlain to a 

depth of more than a thousand feet by shale 

and limestone beds of Paleozoic age that are 

not considered to be water-bearing. An alternate site (24,table 4) was selected farther 

west where water can be obtained from the 

Tensleep Sandstone of P ennsyIvanian and 

Early Permian age. The depth to water and 

pumping lift are based on data from wells E17 

and D5 (table 4).

Site 22 (table 4) is on the east side of a 

strike valley eroded insouthwestward dipping 

beds of Jurassic age. In most respects the 

setting is like that at site 24 (table 4) except 

that the inferred aquifer is sandstone in the 

Sundance Formation of Late Jurassic age. 

The main difference is that beds underlying 

the site are not recharged directly by runoff 

from the mountain because they are truncated 

around the margins of Black Butte dome, a 

small upwarp that lies between the site and 

the mountain front. In the absence of any 

wells or springs in the strike valley under 

consideration, the occurrence and depth to 

water can only be inferred.

Site 25 (table 4) is near the axis of Gypsum 

Creek syncline at the south end of Big Pryor 

Mountain. The site is underlain by interbedded sandstone and shale of the Chugwater 

Formation of Triassic age. A spring (S4, 

table 4) issues from a sandstone bed in the 

Chugwater Formation about half a mile northeast of and at a higher altitude than the site. 

It is virtually assured that water will be 

found in this sandstone bed at the site at 

about the estimated depth. The water will be 

high in mineral content, but like that of the 

spring, it should be suitable for watering 

stock.

BUREAU OF LAND MANAGEMENT ELKO GRAZING 

DISTRICT

The Elko Grazing District includes all of 

Elko County and parts of Eureka and Lander 

Counties. Explorations for water in 1960 were 

made in four widely scattered areas where 

four well sites were examined. Information 

on wells drilled as a result of recommendations in 1960 or previous years (wells D4 and 

D5) is given in table 5. Recommendations for 

stock-water sources were based on field examinations by the author and F. F. Zdenek of 

the Geological Survey and reports by Hains, 

Van Sickle, and Ryals (1949),and Granger and 

others (1957).

Wendover area

The valley northwest of Wendover (3, fig. 1) 

was visited in September, and well site Dl 

(table 5) was selected on the flank of the 

Toana Mountains. The location considered to 

be the most favorable for exploratory drilling 

was high up on the valley edge in the mouth 

of a small embayment, known locally as 

Morris Basin. Alluvium from the basin has 

accumulated here, being held in placeby relic 

terraces left by the Pleistocene Lake Bonneville. It was anticipated that water might be 

moving out of the mountains eastward toward 

the alluvium-filled valley. This site was subsequently drilled and abandoned after 90 feet

of alluvium overlying bedrock was found 

to be non-water-bearing.

Salmon Falls River area

Salmon Falls River area (2, fig. 1) was 

visited in September by F.F. Zdenek who selected site 1 (table 5) along a dry wash that 

is tributary to the Salmon Falls River. In 

this area the river occupies a fault-formed 

valley that has been filled with fluvial and 

lacustrine deposits that are part of the Hum - 

boldt Formation of (Miocene and Pliocene (?)) 

Tertiary age. In places Quaternary alluvial 

deposits overlie the Humboldt Formation. 

These formations are almost everywhere 

permeable and are aquifers in nearby areas. 

Zdenek visited well E2 (table 5) which had 

water at a reported depth of 87 feet. Differences in elevation between this well and the 

proposed site make it appear that drilling 

may have to be continued to a depth of 600 

feet unless shallower permeable beds are 

discovered.

Susie Creek Valley

Susie Creek Valley (4, fig. 1) was visited in 

September, and well site D2 (table 5) was located in a narrow, tributary valley about a 

mile east of Susie Creek. Susie Creek and 

its tributaries have trenched the Humboldt 

Formation exposing several hundred feet of 

lacustrine sediments, largely silt and clay, 

interbedded with thick accumulations of water-laid volcanic ash. The Humboldt Formation is widely distributed in northeastern 

Nevada and is usually water bearing at or 

slightly above the level of the master stream. 

A well was drilled at the selected location, 

and water was reached at 65 feet, which is 

slightly above the level of Susie Creek.

Boulder Valley

The Boulder Valley area (1, fig. 1) was visited in June, and well site D3 (table 5) was 

selected on the valley floor to replace well 

El which was dry. Boulder Valley appears 

to have been formed by a meander of the 

Humboldt River that cut northward into the 

Tuscarora Mountains. This valley and the 

valley of the Humboldt River are filled with 

a continuous body of saturated alluvium. 

After the examination in June the well was 

drilled and an adequate supply of water obtained from an aquifer whose top is at a 

depth of 146 feet.
14 EXPLORATIONS FOR WATER SUPPLIES ON THE PUBLIC DOMAIN, 1960

BUREAU OF LAND MANAGEMENT PYRAMID GRAZING 

DISTRICT

The Pyramid Grazing District includes all 

of Humboldt County and parts of Pershing and 

Washoe Counties. Explorations for water in 

1960 were made in four rather widely spaced 

areas and eight well sites were examined. 

Information on five wells drilled as a result 

cf recommendations made in 1960 and previous years is given in table 5. Recommendations for stock-water sources were based 

on field examinations by the author and F. F. 

Zdenek of the Geological Survey and a report 

by Peter son (written communication, 1945).

Quinn River Valley

Quinn River Valley (7, fig. 1) was visited 

first in July and later in November and four 

well sites (4, D6, D7, and D9, table 5) were 

selected for drilling into the valley alluvium. 

Quinn River Valley is a sprawling downdropped valley surrounded by mountains. 

The valley alluvium is hundreds to thousands 

of feet thick in the valley center and a few 

tens of feet thick on the valley margins. Alluvial fans form a transition zone between 

the mountains and the valley. Older rocks of 

the down-dropped block underlie the valley 

fill. Unless it contains thick bodies of clay 

or silt the valley fill usually is permeable 

and contains ground water that moves from 

the mountains toward the valley center. Permeability throughout the valley fill is not uniform as the formation is a heterogeneous 

mixture with layers of coarse (permeable) 

material interbedded with the impermeable, 

fine-grained, sediments. The geology and hydrology of Quinn River Valley are characteristic of most valleys of the Pyramid Grazing 

District. Ground water occurs at varying 

depths in the valley fill of Quinn River Valley 

and most wells attempted in the valley have 

been successful except where there is shallow bedrock. Three wells, D6, D7, and D9, 

have been drilled to date (May 1961). Of 

these, the well at site D9 had water at 75 feet 

and the drilling at sites D6 and D7 has been 

temporarily suspended.

Desert Valley

Desert Valley (8, fig. 1) is an alluviumfilled valley that is parallel to and just west 

of Quinn River Valley. Unlike Quinn River 

Valley where the river flows down the length

of the valley Desert Valley is crossed by 

the Quinn River from east to west. This 

valley was visited in July and well site D8 

(table 5) was selected on its northern edge. 

Ground water is moving through the valley 

fill from the mountains toward the Quinn 

River, and well site D8, selected on this 

basis, was drilled in the fall of 1960. Water 

came into the well at a depth of 52 feet but 

stands in the coinpleted well at a depth of 30 

feet below ground surface.

Trinity Range

The Trinity Range (10, fig. 1), a system of 

low hills west of Lovelock, was visited in 

July and well site D10 (table 5) was selected 

for drilling into the alluvium along a dry 

wash. In the area examined,the Quaternary 

alluvium of the streambed overlies Tertiary 

basalt flows with interbedded layers of tuff. 

These formations are water bearing in other 

areas, and exploratory drilling here was believed to be justified on the dual basis of 

potential aquifers and need for water. The 

well was drilled in a nearby canyon having a 

similar geologic setting and was abandoned, 

dry, at 390 feet.

Black Rock Desert

The Black Rock Desert area was visited in 

July and two widely separated well sites (2, 

3, table 5) were examined. Site 2 was selected at a location along an unnamed dry 

stream channel in the mountains east of the 

Black Rock Desert. The alluvium of the 

stream channel is a narrow thread of permeable material underlain by generally impermeable bedrock. The channel, extending 

several miles north of the proposed site, 

may have water moving as underflow toward 

Black Rock Desert. Water is found in similar conditions in many places throughout the 

the surrounding valleys and may logically be 

expected here.

Site 3 was selected on the edge of Black 

Rock Desert about 25 miles northwest of site 

2. This part of the desert is an embayment 

north of the main desert and west of the 

Black Rock Range. It is an alluvial-filled 

basin with alluvial fans around the valley 

edge. Water should occur at a shallow depth 

either in the alluvial fan or in the underlying 

valley fill.

BUREAU OF LAND MANAGEMENT VALE GRAZING 

DISTRICT

The Vale Grazing District includes all of 

Malheur County. Explorations for water in 

1960 were made in four areas where seven 

well sites were examined. Information on 

seven wells drilled as a result of recommendations made in 1960 and previous years is 

given in table 6. Recommendations for stockwater sources were based on a field examination by the author and on a report by Baldwin 

(1959).

Rattlesnake Creek area

This area (l,fig. 1) was visited in September 1959 and in July 1960, and two well sites 

(1, Dl, table 6) were selected. Site Dl is on 

a sagebrush-covered flat near the edge of 

Rattlesnake Creek and beside a dry stream 

channel coming from the east. Rattlesnake 

Creek occupies an alluvium-filled valley that 

has been cut in flat-lying older rocks. The 

alluvium is a widespread but fairly thin deposit, largely restricted to the valley bottom, 

and underlain by a sequence of Tertiary volcanic rocks and lacustrine sediments. These 

rocks, consisting of tuffaceous silt stone and 

sandstone with interbedded basalt flows, occur over much of the area east and south of 

U.S. Highway 95. Their water-bearing properties are not well established, but in other 

areas similar rocks are known to be permeable and will yield enough water for stock. 

Water occurs as underflow in the alluvium of 

Rattlesnake Creek, usually less than 1 foot 

below the surface. Wells El and E2 (table 6) 

are in this alluvium. It was concluded that 

water was moving from the southeast and 

east toward Rattlesnake Creek. A well was 

drilled at site Dl and water was reached at a 

depth of 295 feet.

Site 1 is on the south edge of the valley 

about 5 miles southwest of site Dl where a 

well drilled into the alluvium (of the same 

valley) should be successful.

East side of the Owyhee River

This area (2, fig. 1) was visited in July 1960 

and three locations (2 4, table 6) were examined. The area east of the Owyhee River 

between sites 2 and 3 is underlain by flatlying beds of lava and volcanic ash that have 

been deposited over older volcanic rock that 

has been tentatively identified as rhyolite. 

The flat-lying beds above the rhyolite are 

permeable and carry water at or below the 

level of the river. The rhyolite is exposed 

only at scattered locations in the canyon 

walls. It is believed that the flat-lying beds 

were deposited over an old land surface of 

moderate relief, which had been formed on 

the rhyolite. The ryholite is usually massive 

and is not known to be water bearing. Limited occurrences of Quaternary alluvium are 

found on top of the flat-lying beds of lava and 

volcanic ash. These bodies of alluvium are 

small and may or may not contain water. 

Site 2 was recommended for exploratory 

drilling into beds underlying a lava-capped 

plateau between the Owyhee River and Jordon 

Creek. A well drilled here probably will be 

successful unless the rhyolite is above river 

level, in which case the chances for obtaining 

water are small. The estimated drilling 

depth is 400 to 500 feet.

Sites 3 and 4 are on a lava-capped plateau 

east of the Owyhee River Canyon. A large 

body of rhyolite is exposed in the canyon 

where the river has cut through several hundred feet of the non-water-bearing material. 

Site 3 was rejected because the rhyolite exposed in the canyon nearby very likely extends under this site. Moreover, the total 

drilling depth to river level, about 1,200 feet, 

is prohibitive. Site 4 was selected as a place 

to explore the shallow alluvial fill of a small 

closed basin lying just east of the Owyhee 

Canyon. No other well sites appear feasible 

so exploratory drilling at this location may 

be justified. The alluvial fill here probably 

is not thick. Deeper drilling into the rocks 

underlying the alluvium is not justified.

18 EXPLORATIONS FOR WATER SUPPLIES ON THE PUBLIC DOMAIN. 1960

(table 6) lies beside an unnamed tributary of 

Oregon Canyon Creek. This part of the Quinn 

River Valley is filled with alluvium that contains water at a fairly shallow depth as shown 

by two nearby wells (E3, E4, table 6) in both 

of which water stands at less than 10 feet 

below ground surface. Water probably is 

moving southward through the alluvium from 

the mountains toward Quinn River Valley.

Whitehorse Ranch basin

Well site 6 (table 6) is in a small closed 

basin known informally as the Whitehorse 

Ranch basin (4, fig. 1). This basin has no 

known outlet to nearby valleys. The valley 

has been filled with a considerable thickness 

of alluvium. Surface water enters the basin 

from hills to the south and southeast through 

a well-defined drainage system, but most of 

it goes into the ground near the southern 

edge of the valley where the valley floor is 

covered with sand dunes that absorb water 

rapidly. Water should be found here at less 

than 100 feet below the surface.

BUREAU OF LAND MANAGEMENT PRINEVILLE 

GRAZING DISTRICT

ThePrineville Grazing District comprises 

parts of Crook, Deschutes, and Lake Countiea 

Explorations for water were made in October 

1960 for 12 well sites (table 6). Recommendations for stock-water sources were based 

on a field examination by F.F. Zdenek of the 

Geological Survey and reports by Baldwin 

(1959),Bowman1 , Lowry2 ,and Russell(1905).

Dry River valley area

The Dry River valley area in central 

Oregon was visited by Zdenek in October, at 

which time seven well sites were examined 

near Hampton and five were examined near 

Millican. Geologically this part of central 

Oregon is a transition zone wherein the rocks 

of the Columbia Plateau are broken by faults 

of the Great Basin type. Rocks underlying 

the area consist of basaltic and andesitic 

lava flows with interbedded tuff and agglomeate. Locally alluvium has accumulated in 

some of the fault-enclosed valleys. Continuity of the volcanic formations has been interrupted by numerous high-angle normal

and Deschutes County,Oregon: Oregon State College, unpublished 

masters thesis.

faults that have a northwest ward trend across 

the area. Water has been obtained by digging 

or drilling wells into the surficial alluvium 

and deeper drilling into but not through the 

underlying beds of lava and volcanic ash. 

Marked differences in depth to water between 

neighboring wells both of which are drilled 

to water in the volcanic rocks are commonplace; differences as great as 200 feet have 

been reported. These differences are caused 

by faults offsetting the water-bearing beds. 

It is possible that water may occur in the 

alluvium at sites 8 13 in the Hampton area 

and at sites 14, 15, and 17 in the Millican 

area. If water does not occur near the base 

of the alluvium, the possibility still remains 

that water may be found at depth in the volcanic rocks.

UTAH

By CHARLES E. SLOAN

Grazing Districts 6 and 9 are in San Juan 

and Grand Counties, Utah, respectively. Exploration for water in 1960 was made in five 

areas where nine well sites were located. 

Recommendations for stock-water sources 

were based on field examinations by the 

author and M. C. Van Lewen.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 6

The Bluff area

The Bluff area (1, fig. 1) is north of the 

San Juan River in the vicinity of the town of 

Bluff and extends from Butler Wash on the 

west to Recapture Creek on the east. Sites 

1 and 2 (table 7) were selected on Bluff Bench, 

a mesa underlain by the Bluff Sandstone that 

extends from Cottonwood Creek to Recapture 

Creek. Sites 3 and 4 were selected on Tank 

Mesa, a counterpart of Bluff Bench, that extends from Butler Wash to Cottonwood Creek. 

The formations in this general area dip 

gently eastward from Comb Ridge monocline
UTAH 19

toward the Sage Plains down warp. Springs 

of low discharge (S1-S3, table 7) occur in 

most of the canyons that dissect the mesa 

indicating that there is a thin body of perched 

ground water in the basal part of the Bluff 

Sandstone of Late Jurassic age. The underlying Summerville Formation of Late Jurassic age is a relatively impermeable barrier that retards or prevents the downward 

movement of ground water.

Lime Ridge area

The Lime Ridge area (2, fig. 1) is in the 

rugged canyon country north of the San Juan 

River between Comb Wash and Lime Creek. 

Water is needed (site 5, table 7) on an anticline more than a thousand feet above the 

level of the nearby San Juan River. In addition to the unfavorable topographic and structural setting of the site, the general area is 

under lain to a considerable depth by the relatively impermeable Cutler (Permian age) and 

Rico (Pennsylvanian and Permian(?) age) 

Formations. Electric and radioactivity logs

show no indication of water-bearing beds to 

a depth of about 1,500 feet.

Red House area

The Red House area (3, fig. 1) is near the 

head of Steer Gulch at the northern end of 

Grand Gulch Plateau where the broad plateau 

surface abuts the higher surface of Red House 

Mesa. Well-site 6 (table 7) was selected 

on the plateau surface just north of Clay Hills 

Road in a small erosional reentrant in the 

mesa.

Grand Gulch Plateau is underlain by the 

Cedar Mesa Sandstone Member of the Cutler 

Formation, which locally reaches an estimated thickness of 900 feet. Three small 

springs (S4 S6, table 7) issue above a shale 

parting in the sandstone at the head of Grand 

Gulch and are interpreted as an indication of 

perched water. Electric and radioactivity

logs from the Southern Union Oil Co. Federal 

No. 1 oil test well in sec. 22, T. 38 S., R. 16 E., 

also suggest that water may be obtained from 

this perched zone in the Cedar Mesa Sandstone Member. This zone would be reached 

at the proposed site at a depth of about 475 

feet.

Harts Point area

Harts Point (4, fig. 1) is a high, elongate, 

northwest trending finger of land between the 

canyons of Harts Draw and Indian Creek 

about 15 miles east of the confluence of the 

Colorado and the Green Rivers. Harts Point 

is immediately underlain by the Navajo Sandstone which dips about 1° NE toward Harts 

Draw. The Navajo Sandstone (Triassic(?) and 

(Jurassic) in txirn is underlain by shale of the 

Kayenta Formation (Late Triassic) that is a 

barrier to the downward movement of ground 

water. Springs (S7 and S8, table 7) in Harts 

Draw on the downdip side of the point, and 

well (El) on Harts Point, indicate locally 

perched water in the lower part of the Navajo 

Sandstone. Well site 7 was located so as to 

tap this water-bearing zone.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 9

The area examined (5, fig. 1) is at the north 

end of Dome Plateau about 6 miles west of 

Dewey Bridge where Utah Highway 128 

crosses the Colorado River. The site proposed by the Bureau of Land Management (8, 

table 7) is on the north flank of a large domal 

structure in what is considered a very unfavorable geologic and topographic setting. 

Therefore, an alternate site (9) was selected 

about li miles southwest of site 8 near the 

axis of a syncline that separates the larger 

structure from the comparatively small Yellow Cat dome. Site 9 is both topographically 

and stratigraphically lower than site 8 so 

that chances are much better that water will 

be found at comparatively shallow depth in 

the lower part of the Entrada Sandstone of 

Late Jurassic age.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 2

By M. C. VAN LEWEN

The Bureau of Land Management Grazing 

District 2 comprises parts of Fremont and 

Natrona Counties. Explorations for water in 

1960 were made in 2 areas where 11 well 

sites were located. Information on eight 

wells, drilled as a result of recommendations made in 1960 and previous years, is 

given in table 8. Recommendations for stockwater sources were based on field examinations by the author and R. W. Lichty and on 

reports by Thompson, Troyer, White, and 

Pipiringos (1950), Thompson and White (1954), 

and Tourtelot (1953).

Government Draw area

Well sites 1, Dl, and D2 (table 8) east of 

Lander are near the drainage divide that separates Government Draw and Beaver Creek 

(1, fig. 1). This area is underlain by, in descending order, the Wind River (Eocene), 

Fort Union (Paleocene), and Mesaverde (Late 

Cretaceous) Formations and the Cody Shale 

(Late Cretaceous). These formations all 

strike northwestward and dip northeastward. 

An angular unconformity exists between the 

Wind River Formation, which dips 2° 3°, and 

the Fort Union Formation, which dips 12° 

14°. Angular unconformities of about 2° occur between the Fort Union and Mesaverde 

Formations, and between the Mesaverde Formation and the Cody Shale. All these formations contain permeable beds that, if saturated, will yield water to wells.

Although there are two stock-water wells 

in the area (El, E2) that obtain water from the 

Wind River Formation and from the Cody 

Shale, the results of drilling at sites Dl and 

D2 indicate that wells drilled on or near the 

drainage divide may not obtain an adequate 

yield. A much better place for developing 

successful wells is in the Wind River Formation on the broad surface that dips northeastward to Beaver Creek. Future wells should 

be drilled at least half a mile, and preferably 

a mile, northeast of the drainage divide in 

order to obtain a yield adequate for stock 

needs.
22 EXPLORATIONS FOR WATER SUPPLIES ON THE PUBLIC DOMAIN, 1960

Shoshone-Moneta area

Well sites 2, 3, and D3-D8 (table 8) in the 

northern part of the Wind River basin (2, fig. 

1) are underlain by the Wind River Formation, which consists of pockets and lenses of 

sandstone erratically distributed throughout 

a thickness of several thousand feet of multicolored shale. Because the lithology of this 

formation changes radically within short distances, it is generally not possible to predict 

closely the required drilling depth at a particular location. The results of drilling at six 

of the above sites (D3 D8) show that, if several wells are to be drilled, the total footage 

drilled will be reasonably close to the total 

estimated footage.

Water found at shallow depth in this area is 

frequently of poorer quality than water found 

at greater depth. Where this happens, the 

water obtained at shallow depth is usually 

cased off and drilling is continued until water 

of better quality is obtained. Water in the 

Wind River Formation in this area is commonly under artesian pressure.

BUREAU OF LAND MANAGEMENT GRAZING DISTRICT 

4 and 5

By M. C. VAN LEWEN

The Bureau of Land Management Grazing 

Districts 4 and 5 comprise parts of Sweet - 

water, Lincoln, Uinta, and Sublette Counties. 

Explorations for water in 1960 were made in 

the Bridger Basin (3, fig. 1) part of which is 

in the northern part of District 4 and the remainder of which is in District 5, where 36 

well sites were located. Information is given 

on 7 wells drilled as a result of recommendations made in 1960. Recommendations for 

stock-water sources were based on field examinations by the author and R. W. Lichty 

and on reports by Bradley (1926, 1959), Donovan (1950), and Gordon and others (1960).

The well sites (4-29, D9-D18, table 8) examined are all in the northern half of the 

Bridger Basin. Ground water occurs under 

sufficiently similar conditions throughout the 

area bounded by the Wind River Mountains on 

the northeast, Steamboat and Essex Mountains 

on the southeast, the township line between 

Townships 21 and 22 north on the south, and 

the Wyoming Range on the west that it may 

be described as a unit. Bedrock in this area

consists of indurated sediments of the Wasatch, Green River, and Bridger Formations 

all Eocene age that were deposited in and 

along the margins of the ancient Green River 

Lake. Bradley (1926) and Donovan (1950) described the depositional environment that resulted in the intertonguing of the Wasatch and 

Green River Formations. Gordon and others 

(1960) describe the occurrence and quality of 

water in the northern Bridger Basin.

Both the uppermost part of the Green River 

Formation and the overlying Bridger Formation consist of interbedded standstone and 

shale, and these units contain many more 

permeable beds than does the main body of 

the Green River Formation. An analysis of 

driller's logs of numerous wells drilled in 

the Little Colorado Desert west of Farson 

between Sandy Creek and the Green River 

permits some generalizations of the lithology 

and water-bearing properties of the formations. Rocks found near the axis of the basin 

are not readily correlated with exposures 

along the margin of the basin. Sandstone 

beds are generally not continuous from one 

well to another only a few miles away. 

Yields in excess of 40 gpm have been obtained from the Bridger Formation and from 

the upper part of the Green River Formation from wells along the major ephemeral 

streams tapping these horizons. Wells in upland areas away from the stream valleys, 

however, obtain only small yields from these 

same stratigraphic horizons. To obtain 

yields in excess of 20 gpm in these parts of 

the area, it is generally necessary to drill 

much deeper, probably to a tongue of the 

Wasatch Formation.

Along the east and west margins and 

throughout the northern part of the northern 

Bridger Basin the Wasatch Formation is recharged by perennial surface streams, so 

that stock-water wells of adequate yield are 

usually obtained at a depth of less than 200 

feet. A few wells drilled into the Wasatch 

Formation on the mesa south of Pinedale indicate that small amounts of water may be 

obtained at elevations considerably above the 

level of the nearby New Fork and Green 

Rivers.

Water in^the Wasatch, Green River, and 

Bridger Formations is-Ordinarily under artesian pressure, and some flowing wells 

have been developed. All water obtained
WYOMING 23

from these formations in this area is suitable 

for stock use.

BUREAU OF LAND MANAGEMENT GBAZING DISTRICT 6

By CHARLES E. SLOAN

Bureau of Land Management Grazing District 6 comprises parts of Johnson and Natrona Counties and scattered land utilization 

tracts in eastern Wyoming and adjacent 

States. Exploration for water in 1960 was 

made in three areas where six well sites 

were chosen, one of which was drilled in 1960. 

Recommendations for stock-water sources 

were based on field examinations by the 

author.

Alkali Creek area

Two well sites (30 and D19, table 8) were 

selected in August in the Alkali Creek area 

(4, fig. 1) near Arminto in the eastern part 

of the Wind River Basin. Both sites are underlain by the Wind River Formation of Eocene age, which has accumulated to considerable thickness in a deep, northwestward 

trending synclinal trough that separates Cedar Ridge on the southwest from Arminto anticline on the northeast. The Wind River 

Formation locally consists of interbedded 

shale, siltstone, sandstone, and conglomerate 

of fluvial and lacustrine origin. Both sites 

were chosen on the basis of three wells (ESSES?) that obtain water at a comparatively 

shallow depth from sandstone lenses in the 

Wind River Formation within a few miles of 

the sites. However, the well drilled at the 

Donlin 1 site (D19) penetrated only "blue clay" 

to a depth of 300 feet where drilling was discontinued. Thus, the distribution of sandstone 

lenses in the Wind River Formation appears 

to be erratic and not locally predictable. Successful completion of wells in this area involves an element of risk, therefore, as water 

can be found only in permeable sandstone 

lenses below the local level of saturation.

Bonnidee area

Well site 31 near the head of Curtis Draw 

in the southern part of the Powder River 

Basin (5, fig. 1) was examined in August. The 

site is about 4 miles west of the Powder River 

and 250 feet higher. Westward dipping, interbedded sandstone, siltstone, shale, and coal 

of the Wasatch Formation crop out in the

slopes between the site and the river and underlie this general area to a depth of several 

thousand feet.

Well ESS, about half a mile east of the site, 

indicates that permeable beds occur locally 

within the Wasatch Formation, and that below 

the level of the Powder River these beds 

should be water bearing.

Williams Draw area

Three well sites (32 34,table 8) were examined in August in the Williams Draw area 

(6, fig. 1) which is immediately east of the 

Powder River in the central part of the Powder River basin. The Wasatch Formation, 

consisting largely of interbedded sandstone, 

siltstone, shale, and coal, underlies the area 

to a depth of several thousand feet. Data 

from wells E39 E41 indicate that the Powder 

River reflects the general level of saturation 

in the Wasatch Formation. Thus, successful 

well completion depends on penetrating a 

permeable zone below this level. Owing to 

the dip of the beds and the confining effect of 

the shales, the water apparently is under 

artesian pressure throughout the area.
