GROUND-WATER RESOURCES OF 

ATASCOSA COUNTY, TEXAS

By R. W. SUNDSTROM and C. R. FOLLETT

ABSTRACT

Atascosa County, Tex., is underlain by water-bearing sands of Tertiary age 

that furnish water for domestic and stock supplies throughout the county, for the 

public supply of all except one of the towns and cities in the county, for irrigation 

in several localities, for drilling oil wells in the central and southern parts of the 

county, for washing glass sand in the northern part of the county, and for maintaining several lakes that are used for hunting and fishing. By far the most 

productive formation is the Carrizo sand, but supplies of considerable magnitude 

are also obtained from sands in the Mount Selman and Cook Mountain formations.

The rate of withdrawal from the Carrizo sand amounted to about 15,500 acrefeet a year in 1944-45 or an average of about 13.8 million gallons a day. This 

was about 6,000 acre-feet a year greater in 1944-45 than it was in 1929-30. Of 

the total amount of water withdrawn in 1944-45 about 6,500 acre-feet a year is 

largely wasted from uncontrolled flowing wells. If the waste of water from wells 

in the Carrizo sand were stopped, the consumption of water for useful purposes 

could be increased about 70 percent without increasing the draft on the underground reservoir.

The increase in total withdrawals from the Carrizo sand has been accompanied 

by a general decline in the artesian head between 1929-30 and 1944 ranging from 

3 to 25 feet. On the whole, the evidence shows that the artesian reservoir is not 

being overdrawn and that it will sustain a somewhat greater draft.

INTRODUCTION

Atascosa County, Tex., is underlain by water-bearing sands in 

several geologic formations. Wells in these sands furnish water for 

domestic purposes and stock throughout the county; for the public 

supply of all the towns and cities except Campbellton, which uses 

river water; for irrigation in several localities; for drilling oil wells in 

the central part of the county; for washing glass sand in the northern 

part of the county; and for maintaining several lakes that are used for 

hunting and fishing. By far the most productive formation is the 

Carrizo sand, but supplies of considerable magnitude are also obtained 

from sands in the Mount Selman and Cook Mountain formations. 

In many localities the wells in these formations flow, and much water

is wasted.

PREVIOUS INVESTIGATIONS

The geology and ground-water resources of Atascosa and Frio 

Counties were investigated during the summers of 1929 and 1930, in 

December 1931, and in June 1932 as a cooperative project between

107
108 CONTRIBUTIONS TO HYDROLOGY, 1945-47

the Engineering Experiment Station of the Texas Agricultural and 

Mechanical College, the United States Geological Survey, and the 

Texas Board of Water Engineers. The work was done by John T. 

Lonsdale, under the direction of W. N. White of the Geological 

Survey, who is in charge of ground-water investigations in Texas. 

In February 1931 a report l was released to the press giving a summary 

of the results of ground-water surveys in several counties in southwestern Texas, including the work by Lonsdale. In 1935 a detailed 

report 2 was published by the Geological Survey giving the results of 

the survey in Atascosa and Frio Counties.

PURPOSE OP THIS INVESTIGATION

Since Lonsdale's investigation was made many new wells have been 

drilled, withdrawals of ground water have increased materially, and 

artesian pressures have declined in most of the county. As a result 

of this decline, many of the irrigation farmers have become alarmed, 

particularly those who irrigate from flowing wells.

In the spring of 1944 the Atascosa County Soil Conservation District, composed of a large group of farmers, made a formal request 

to the Texas State Board of Water Engineers for further ground-water 

studies, with special reference to the increase in the development of 

ground water and the effect that it has had on the principal artesian 

reservoirs. In response to this request made through Mr. John B. 

Temple, chairman of the Conservation Board, an investigation was 

conducted by the writers in May and June 1944 and in August 1945. 

In the course of these investigations, records of 130 wells that had 

been drilled since 1929-30 were obtained, the discharge of many wells 

both flowing and pumped was measured, artesian pressures in many 

of the flowing wells were recorded, and water-level measurements 

were made in numerous wells that do not flow. Figures were compiled on the amount of land under irrigation from wells and the quantities of water used for all purposes. Samples of water were obtained 

from numerous wells and were analyzed in the chemical laboratory 

of the Geological Survey and the Texas Board of Water Engineers at 

Austin. A large part of the data thus assembled is given in the 

well records, well logs, and water-well analyses in this report.

RELATION OP THE GEOLOGY TO THE OCCURRENCE OP GROUND

WATER

The geology of Atascosa County and its relation to the occurrence 

of ground water was discussed in considerable detail by Lonsdale and 

will be reviewed only briefly here.

GROUND-WATER RESOURCES OF ATASCOSA COUNTY, TEX. 109

The rock formations exposed in the county are of Quaternary and 

Tertiary age, but rocks of Cretaceous age have been identified in 

several deep oil tests in the central and northern parts of the county. 

So far as the occurrence of usable ground water is concerned, only 

the formations of Tertiary age are important. The Quaternary stream 

and terrace deposits are thin and yield little or no water, and the 

Cretaceous rocks contain salty water. The Tertiary formations, 

named in the order of age from older to younger, are the Indio formation of the Wilcox group, Carrizo sand, Mount Selman formation, 

Cook Mountain formation, Yegua formation, and the Jackson 

formation.

Except in localities where there are notable folds or faults, the rocks 

in most places dip to the south or southeast, which is also the general 

direction in which the land surface slopes. However, the dip is 

nearly everywhere steeper than the slope of the land surface, and 

therefore successively younger formations are encountered in crossing 

the area from north to south or from northwest to southeast. Each 

formation has an outcrop area from which it extends toward the south 

or southeast below the younger formations to progressively greater 

depths below the surface. Thus the formations that appear at the 

surface in the northern part of the county occur at depths of several 

thousand feet in the southern and southeastern parts of the county. 

For example, the Carrizo sand, which is at the surface in the northern 

part of the county (see pi. 2), is found at a depth of about 4,000 feet 

near Campbellton, in the southeastern part of the county.

The structure of the rocks in Atascosa County is favorable for the 

occurrence of artesian water. The formations are composed largely 

of permeable sands interbedded with relatively impermeable clays 

and shales. The source of the water supply in the permeable sands 

is the rain that falls on their outcrop areas and seepage from streams 

that rise farther north and flow southward across these areas. A part 

of the rain and stream water penetrates to the water table in the 

outcrop areas and thence percolates slowly down the dip to greater 

and greater depths. The water, being confined in the sands between 

beds of impermeable clay or shale, is under hydrostatic pressure from 

higher levels in the outcrop areas, and in localities having an elevation 

considerably below the general level of the outcrops the pressure is 

great enough to produce artesian flow in wells.

DEVELOPMENT OF GROUND WATER

CARRIZO SAND 

IRRIGATION

The production of ground crops in the Poteet area of northern 

Atascosa County, especially vegetables and strawberries, by means 

of irrigation from wells in the Carrizo sand (see pi. 2 and well records)
110 CONTRIBUTIONS TO HYDROLOGY, 1945-47

started about 1904. It is believed that in the early days of this 

development all the wells flowed. Later many of them were equipped 

with pumps. The first irrigation well, a flowing well, was drilled at 

Poteet in 1904 before the advent of the railroad. By 1910, 10 flowing 

wells were in use, of which several were used for irrigation, and thereafter several were drilled each year until World War I, when the 

development was stopped on account of the high cost of drilling the 

wells and providing them with equipment where this was needed. 

After the war the development was resumed.

In 1929-30, 57 wells in the Carrizo sand were used for irrigation, of 

which 41 had a flow; a total of 1,350 acres was irrigated from them, and 

about 3,200 acre-feet of water (2.4 acre-feet per acre) was used. This 

is the equivalent of about 2.9 million gallons of water a day through 

the year.

As shown by the Lonsdale report, 3 most of the irrigation in 1929-30 

was in the northern part of the county near Poteet and was restricted 

generally to the lower lands in the Atascosa Kiver Valley, only a few 

wells being on higher land at some distance from the stream. Most 

of the irrigation wells were within 5 miles of Poteet.

In 1945, 108 wells in the Carrizo sand were used for irrigation in 

Atascosa County, of which 51 were flowing wells; a total of about 

3,544 acres was irrigated, and 7,900 acre-feet of water (2.2 acre-feet 

per acre) was used. This represents an average of about 7 million 

gallons of water a day throughout the year. Of the total number of 

wells in use, 98 were within a territory which still may be designated 

as the Poteet area although its former boundaries have expanded in 

all directions, the wells farthest west now. being about 10 miles from 

the town and those farthest east about 5 miles from the town (see 

pi. 2). Of the total number of acres under irrigation about 2,800 

acres are in the Poteet area.

PUBLIC, INDUSTRIAL, DOMESTIC, AND STOCK USB

Wells in the Carrizo sand furnish the public supplies of Poteet, 

North Pleasanton, and Jourdanton. The total average consumption 

by the three towns is about 125,000 gallons a day, according to the 

water superintendents. An average of 60,000 to 70,000 gallons a day 

is pumped from a well in the Carrizo sand in the northern part of 

the county for washing sand for the manufacture of glass. Oil-well 

drilling, mostly in the central part of the county, requires an estimated 

average of half a million gallons of water a day. Many of the wells 

in the Carrizo sand are used for domestic purposes and stock, but the 

total consumption is not large. However, in order to provide water 

for stock, several of the irrigation wells of large flow are allowed to

3 Lonsdale, John T., op. eit., pi. 1.
GROUND-WATER RESOURCES OF ATASCOSA' COUNTY, TEX. Ill

remain open when they are not needed for irrigation, and from some 

of them large quantities are wasted.

WASTE OF WATER

During the survey in 1944-45 all flowing wells in the Carrizo sand 

were visited, and when it was possible the flow of each well was 

measured with a current meter or weir, or with a 10-gallon container. 

Where measurements could not be made the flow was carefully estimated. Altogether, 76 flowing Carrizo wells were visited. The rate 

of flow varied from less than a gallon a minute to as much as 500 

gallons a minute (see well records, pp. 118-143). The combined flow 

from the 76 wells amounted to about 10,300 gallons a minute, the 

equivalent of 14.8 million gallons a day or 16,700 acre-feet a year. 

Of the total flow, it is estimated that an average of about 6,300 gallons 

a minute is regulated by valves and put to beneficial use for irrigation 

or other purposes. The remaining 4,000 gallons a minute (about 5.8 

million gallons a day) is mostly wasted, although some of it is used to 

supply artificial lakes for hunting and fishing or to maintain a flow in 

streams for watering stock during dry periods. These figures were 

compiled mostly from measurements made in May 1944 during a period 

when very little water was needed for irrigation and when most of the 

pumps, with which the nonflowing irrigation wells and some of the 

flowing wells are equipped, were idle. At such a time the artesian 

head in the aquifer is higher and the waste of water from the uncontrolled wells is somewhat greater than during periods of heavy 

irrigation.

TOTAL WITHDRAWALS IN 1929-30 COMPARED WITH THE TOTAL IN 1944-46

The following table gives the estimated withdrawals of water from 

the Carrizo sand in 1929-30 and in 1944-45. The figures show that 

the withdrawals were about 6,000 acre-feet, or 63 percent, greater in 

the last period than in the first one.

NET DECLINE IN ARTESIAN HEAD

In 1929-30 Lonsdale recorded the artesian head as shown by the 

shut-in pressures in 72 Carrizo wells in Atascosa County. In 1944-45 

such measurements were made in 76 Carrizo wells, of which 31 had 

been measured by Lonsdale. The table below gives the results of 

the two sets of measurements for comparison:

> Measurement made in well 244 in 1929-30 and in well 77 (about 50 feet from well 244) in 1944.

The largest decline between 1929-30 and 1944 occurred in well 244 

at Pleasanton and in well 249 about 3 miles west of Pleasanton, the 

drop in head amounting to about 25 feet. Both these wells have 

flowed unchecked for many years. Well 249 was flowing at the rate 

of 500 gallons a minute when it was measured in 1945. Well 244 had 

a flow of only 10 gallons a minute, but as the casing is in very poor 

condition the water probably is escaping into upper sands at a rate 

comparable to the flow of well 249 or greater.

Large declines of artesian pressure were observed in the Poteet 

area where the withdrawal of water is heaviest. The water levels or 

artesian pressure in 10 wells Nos. 179, 188, 196, 197, 205, 213, 218, 

226, 230, and 235 showed declines ranging from 11 to 19-feet and 

averaging 15.4 feet between 1929-30 and 1944. Two of these wells, 

Nos. 213 and 226, remeasured in 1945, showed a further decline of
GROUND-WATER RESOURCES OF ATASCOSA' COUNTY, TEX. 113

2.7 feet. In other parts of the Poteet area the decline ranged from 

3 to 10 feet between 1929-30 and 1944. In well 246, about IK miles 

east of Charlotte, the decline amounted to 12.7 feet between 1930 and 

1945. According to the owner of the well the water level was only 2 

feet below the land surface in 1918. The decline from 1918 to 1945 

was, therefore, about 21 feet. In the outcrop area of the Carrizo 

sand the water level in well 168 north of Poteet and hi well 169 north 

of Leming were, respectively, 11.2 and 10.2 feet lower in 1945 than in 

1930. The only available records of fluctuations in water levels in 

any of the wells during the intermediate years (1931 to 1943) are those 

obtained in well 62 by the owner, Mr. Cyril Hooge. These records 

give the results of 1 measurement each year in 1925, 1926, and 1937, 

14 measurements in 1938, 5 in 1940, 1 measurement in 1941, and 1 hi 

1944. The well is about 3 miles east of Poteet in an area of heavy 

withdrawal. The following table gives the fluctuation in feet above

When a well is allowed to flow, or is pumped, the artesian pressure 

(or water level) in the well drops, and a hydraulic gradient is established toward the well from all directions, the gradient taking the 

shape of an inverted cone surrounding the well. This cone spreads 

out if the discharge continues and becomes flatter with increasing 

distance from the well. If a number of wells are allowed to flow, or 

are pumped, the pressure cones tend to merge into a large depression, 

radiating out from the center of ground-water withdrawals. This is 

in accordance with the laws of hydraulics and in itself is no cause for 

alarm. A certain amount of decline in water levels or artesian pressures must occur in every area hi which ground water is developed hi 

considerable quantities. If the rate of withdrawal remains constant 

and the aquifer is not overdrawn, a state of equilibrium should be 

reached in a few years, and the decline should cease or become very 

small. On the other hand, the decline may be expected to continue 

as long as the rate of withdrawal increases. Only when the decline
114 CONTRIBUTIONS TO HYDROLOGY, 1945-47

persists year after year without a corresponding increase in the rate 

of withdrawals is there reason for apprehension. This may indicate a 

serious overdraft.

The decline of artesian pressures in the Carrizo wells of Atascosa 

County since 1929-30 has been caused in part by an increase in withdrawals from the aquifer of about 6,000 acre-feet a year, or about 63 

percent of the draft in 1929-30. The effect of this increase is modified 

if not largely canceled in the figures on net decline between 1929-30 

and 1944, shown in the table on page 112, because the seasonal withdrawals for irrigation where heavy when the measurements were made 

in 1929-30 and very light when the measurements were made in 1944. 

On the other hand, the drop m head between measurements in May 

1944 and August 1945 may have been largely the result of the greater 

seasonal draft for irrigation during the last period. Whether or not 

the decline has reached approximate equilibrium for the present rate 

of pumping cannot be determined with certainty from the data at 

hand. It appears probable, however, that some further decline in 

water levels or artesian pressures may occur if the present rate of 

withdrawals is maintained. If the withdrawals are increased the rate 

of decline will be accelerated. As a result, flowing wells in which the 

artesian head is only slightly above the ground will cease flowing and 

the pumping levels in some of the wells, which are now equipped with 

centrifugal pumps may become so low that other types of pumps will 

have to be installed. On the whole, however, the evidence tends to 

show that the artesian reservoir is not being overdrawn and that it 

would sustain a somewhat greater draft without serious depletion. 

Further observations should throw additional light on this question.

It should be pointed out that the present consumption of water 

from Carrizo wells for all useful purposes such as irrigation, public 

supply, and industrial use could be increased about 70 percent without increasing the draft on the underground reservoir if the present 

annual waste of water were stopped.

QUALITY OP WATER FROM WELLS IN THE CARRIZO SAND

The table of analyses gives the results of chemical tests of water 

from 35 wells in the Carrizo sand in which the iron, bicarbonate, 

sulfate, chloride, and total hardness in the water were determined, 

and results of more complete analyses of water from 13 wells.

MOUNT SELMAN FORMATION

IRRIGATION

Water from the Mount Selman formation is used to some extent for 

irrigation in a few scattered areas 4 to 7 miles east of Pleasanton. In 

1929-30, nine irrigation wells were reported as drawing from this
GROUND-WATER RESOURCES OF ATASCOSA COUNTY, TEX. 115

formation. Since 1930 nine new wells have been drilled but several 

of the earlier wells have been abandoned. In 1945, 13 Mount Selman 

wells were being used for irrigation, and somewhat less than 400 acres 

were irrigated from them.

PUBLIC, DOMESTIC, AND STOCK USE

Wells in sands of the Mount Selman formation furnish the public 

water supplies of Pleasanton, Coughran, and Christine. The total 

average consumption by the three towns does not exceed 80,000 gallons 

a day, according to estimates by the water superintendents. Many 

wells in sands of the Mount Selman formation are used for domestic, 

purposes and stock in the central and south-central part of the county, 

but the total consumption for these purposes is not large.

WASTE OF WATER

In May 1944 the discharge of 22 flowing wells in sands of the Mount 

Selman formation was measured. The flow of the wells ranged from 

less than a gallon a minute to as much as 100 gallons a minute. The 

total discharge of the 22 wells amounted to 714 gallons a minute 

(about a million gallons a day). Of this amount it is estimated that 

about 420 gallons a minute (0.6 million gallons a day) is largely 

wasted.

QUALITY OF WATER

The table of analyses gives the results of determinations of the 

amount of iron, bicarbonate, sulfate, chloride, and total hardness 

present in the water from 29 wells and more complete analyses of 

water from 11 other wells in sands of the Mount Selman formation.

COOK MOUNTAIN, YEGTJA, AND JACKSON FORMATIONS

Wells in the Cook Mountain, Yegua, and Jackson formations 

furnish water for domestic purposes and stock in the central and 

southern parts of the county. The total withdrawal of ground water 

from these formations in Atascosa County is relatively small. In 1944 

the water levels were measured in a few of the wells, and samples of 

water were obtained from a few of them also.

SUMMARY

The total withdrawal of ground water in Atascosa County from the 

Carrizo sand, the principal aquifer, increased from about 9,500 acrefeet a year (8.5 million gallons a day) in 1929-30 to about 15,500 

acre-feet a year (13.8 million gallons a day) in 1944^15. The amount 

used for irrigation increased during the period from 3,200 acre-feet 

a year (2.9 million gallons a day) to 7,900 acre-feet a year (7.0 million 

gallons a day.) The total annual waste of water in 1944^45 6,500
116 CONTRIBUTIONS TO HYDROLOGY, 1945-47

acre-feet (5.8 million gallons a day) was about the same as in 1929-30. 

The average waste from the individual wells was less in 1944-45, but 

the number of wells showing a waste was greater.

The increase in total withdrawals from the formation has been 

accompanied by a general decline in artesian head, the net decline 

between 1929-30 and 1944 ranging from 3 to 25 feet. Equilibrium 

probably has not yet been reached, and some further decline is to be 

expected if the present rate of withdrawals is maintained. If the 

rate of withdrawals is increased the present rate of decline will be 

accelerated. This will cause additional wells to cease flowing and 

may lower the water levels to such an extent in some of the wells 

equipped with centrifugal pumps that the pumps will not deliver water.

On the whole, the evidence tends to show that the artesian reservoir 

is not being overdrawn and that it will sustain a somewhat greater 

draft. Further observations, which are expected to be made, should 

throw additional light on this question.

If the present waste of water from wells in the Carrizo were stopped 

the present consumption of water for all useful purposes could be 

increased about 70 percent without increasing the draft on the underground reservoir. Every man who has a flowing well or pumping 

plant should realize that he and his neighbor in fact, the whole community are drawing from a common reservoir and that any depletion of this reservoir is suffered by all.

The discharge of ground water from flowing wells in the Mount 

Selman formation amounts to about 1,100 acre-feet a year the equivalent of about 1 million gallons a day. The water pumped from nonflowing wells does not add materially to this figure. The decline of 

artesian head in wells in the formation since 1929-30 has been comparatively great. This indicates that the formation cannot be expected to yield very large quantities of water. Some water is wasted 

from Mount Selman wells, but the waste is small.

The total withdrawal of ground water from the Cook Mountain, 

Yegua, and Jackson formations in Atascosa County is relatively 

small.
