ABSTRACT
A total of 152 gill nets were set and 39 seining
collections were made to collect 9,023 specimens of
fish representing 31 species from the Clear Fork of
the Brazos River and its watershed. Desirable game
fish populations were found to be exceedingly scarce
in the river but more abundant in lakes on the water-
shed. Redhorse shiners (Notropis lutrensis) and
stunted sunfish were found to be the most numerous
species in the river while gizzard shad (Dorosoma
cepedianum), channel catfish (Ictalurus punctatus),
and small white crappie (Pomoxis annularis) were
found to be very prevalent in the lakes on the
watershed. The principal fisheries problems were,
in general, found to be excessive populations of
gizzard shad, river carpsucker (Carpiodes carpio)
and stunted crappie and sunfish and widespread
salt water pollution emitting from oil wells, which
has apparently reduced considerably, or completely
eliminated game fish populations in several local~
ities.

Job No. B=16 Title: Basic Survey and Inventory of Species
as Well as Their Distribution in the
Clear Fork of the Brazos River in Region
3-B, Texas
Period Covered: April 16, 1958 - March 31, 1960
OBJECTIVES
To gather fundamental data on the above waters in regard to their physical,
chemical, and biological aspects and to determine the distribution of the species
present, their relative abundance: and the ecological factors influencing their
distribution.
PROCEDURE
The Clear Fork of the Brazos River and its watershed was divided into upper
and lower regions on the basis of its physical and botanical aspects. All physi-
Cal, chemical and biological data were organized and analyzed in relation to the
location from which they were collected. A total of 152 nets were set and 39
seining collections were made on the complete watershed. Of this total 134 netting
collections and 32 seining collections were made in the region designated as the
upper watershed and 18 netting collections and 7 seining collections were made in
the region designated as the lower watershed. A greater number of netting and
seining collections were made in the upper region than in the lower region because
in the upper region there were more lakes to set nets in and more water suitable
for seining. Altogether there were 29 seining collections taken from the river, 5
seining collections taken from tributaries to the river and 5 seining collections
taken from lakes on the watershed. There were 12 netting collections taken from
the river and 140 nets were set in lakes on the watershed. Netting was impossible
in the river's tributaries due to shallow water and narrow creek beds. Some of
the netting collections from lakes were obtained in conjunction with other Dingell-
Johnson work.
The nets used were experimental type gill nets, 125 feet long and & feet deep
with five 25-foot sections of webbing ranging from l-inch to 3-inch square mesh.
Five types of seines were employed in making seine collections. They included
a 12' X k* commonsense seine, a 20' X 6° commonsense seine, a 30' X 6' bag seine
with ¢-inch mesh, a nylon straight seine measuring 50' X 6! with +-inch mesh, and
a nylon straight seine measuring 100' X 6' with $-inch mesh.
--- Page 4 ---
Specimens collected by seining were taken to the laboratory for identification
and study. Samples of each species were preserved in 4 10 percent formalin solution.
Specimens collected by netting were examined in the field for stomach contents and
sexual development and were weighed and measured in order to obtain growth and
condition information. All data collected was recorded on fish collections forms
in the field and later combined and tabulated in the office.
Temperature, pH, and turbidity was recorded at every third station. Water
samples were also collected but it was found that reasonably extensive water analyses
data were available by combining records obtained from the Texas Board of Water
Engineers, the Texas Health Department and the United States Geological Survey.
Physical and botanical observations were also made at various netting and seining
localities during the course of the survey.
No rotenone treatment of pools was attempted on the river or tributaries
because of flowing water or the danger of flowing water in case of rain. It was
feared that this flowing water would cause fish eradication on private property where
permission had not been obtained to conduct such work.
FINDINGS
Although the division of the Clear Fork of the Brazos River into upper and
lower regions was done on the basis of the physical and botanical characteristics
found in each region, the exact line that was selected to divide the two areas.
had to be chosen in a more or less arbitrary manner. No sharp line of topographical
change exists, although there is a definite change in the topography and ecological
aspects of the upper and lower regions. The most logical place to divide the water-
shed was found to be at the Leuders Dam which is located almost on the county line
between Jones and Shackelford Counties. This line extends upward between Haskell
and Throckmorton Counties and downward between Taylor and Callahan Counties. Using
these county lines as a division point between the upper and lower watershed of the
Clear Fork of the Brazos River, Haskell, Jones, Taylor, Fisher, Nolan, and Scurry
Counties are in the upper region. Throckmorton, Shackelford, Callahan, Young,
Stephens, and Eastland Counties are in the lower region.
Physical Characteristics
Upper watershed ~ The Clear Fork of the Brazos River arises in the south-
eastern part of Scurry County from a series of small springs which flow sporadically
and only in periods of heavy moisture. The river in this area is actually more
like a creek, dry much of the time with shallow banks and a narrow bed. Permian
red soils prevail in this area and much ef the land is in cultivation. When the
river flows in this area, it usually contains much red and brown colloidal sus-~
pension. As the stream progresses through Fisher and Jones Counties a muitituce
of creeks, many of which arise in Nolan and Taylor Counties, are added to the water-
shed. This additional drainage area tends to create a more permanent stream, with
wider banks and greater flow in the eastern part of the upper Clear Fork of the
Brazos River watershed. This terrain is also for the most part flat cultivated land
but contains more rolling pasture in the eastern areas. At Nugent, which is the
eastern extremity of the upper region, average annual runoff figures for a period
of 30.6 years equalled 91,770 acre feet. The minimum flow recorded during this
period was 7,830 acre feet and the maximum flow recorded was 518,000 acre feet.
--- Page 5 ---
Lower watershed = The Clear Fork of the Brazos River below the Leuders Dam
is a wider, deeper stream bed that often contains flowing water. The stream bed is
primarily packed sand with limestone projections and there are many large trees
along the banks. The water in this region is usually very clear and the stream is
more deserving of its name as it continues further east. The vegetative cover on
the black and gray soils of this region, the permanence of water, and the presence
of many farm tanks and ponds are probably the main reasons for the less turbid waters
of the area. The terrain in the lower watershed consists mainly of undulating
pasture, and ranching is the chief land use. At Fort Griffin, near the eastern
extremity of the lower region, the average annual runoff figures for a period of 30.8
years equalled 173,300 acre-feet. The minimum flow recorded during this period was
6,370 acre feet and the maximum flow recorded was 711,000 acre-feet.
Aquatic and Shoreline Vegetation
Upper watershed - Aquatic vegetation in the upper region is limited to various
forms of algae and a few patches of bulrushes (Scirpus ), which are located near the
eastern extremity, above the Leuders Dam. Shoreline vegetation is likewise limited.
Mesquite is common and willows, hackberries, chinaberries and pecans are widely
scattered at various iocations along the upper watershed. Sunflowers, and various
weeds and grasses are the principal shoreline vegetative types.
Lower watershed - Besides various types of algae, the principal types of aquatic
vegetation in the lower region appear to be muskgrass (Chara) and coontail (Cerato-
phyllum ). The shoreline supports a profuse vegetation with larger mesquites, pecans,
hackberries, chinaberries, post oaks, and willows being the more common trees.
Various grasses, vines, and brambles are also abundant.
Pollution and Water Quality
Because pollution and bad water quality occur in scattered areas in the water-
shed, according tc where sources of pollution exist, no attempt will be made to give
the results of this investigation according to upper or lower regions. The primary
sources of pollution were found to be cil wells. Salt water escaping from these
weils and invading the sub-surface water supply or flowing directly out of the
ground appears to be the pollutant most seriously affecting the aquatic environment.
Chlorides were found to be present up to 43,800 p.p.m. in one artesian spring on
the banks of California Cresk. California Creek, which is the main tributary of
the Clear Fork of the Brazos River, and the river itself were the only places where
water quality and pollution data was obtained. This water quality data was obtained
from the Texas Board of Water Engineers, the Texas Health Department, and the United
States Geological Survey. Other areas where salt-water pollution was found to exist
included the Clear Fork near Roby and near Eliasville, and the Old Hamlin City Lake.
Old Hamlin City Lake is apparently devoid of all fish except for some very
salt tolerant species. It has been stocked several times with-bass and catfish
from the state hatcheries, but evidently these fish have not survived.
Effluents going into the river near Leuders have been found to be primarily
the washings from a limestone quarry and may even be beneficial to certain species.
The largest shad found in any locality along the river were collected near the point
where the effluent was being discharged.
--- Page 6 ---
Figures ay through 50 give a more complete account of the water quality of
the Clear Fork of the Brazos River. Insufficient dissolved oxygen was not common
and appeared to be a minor fishery problem. The pH values ranged from 7.1 to 8.4,
while 7.7 was the average reading. For more specific and complete water quality
information, the reader is referred to the above named figures.
Fish Populations
The results of the netting and seining collections can best be given in the
following annotated species list and the fishery charts included in this report.
An index to all charts, maps, and pictures is included in this report immediately
preceeding the fishery charts. Figure 10 gives a complete summation of seining
results, while Figure 39 gives a complete summation of netting results. Fishery
information pertaining to more specific areas of the Clear Fork of the Brazos River
watershed can be located by referring to the included index. A total of 9,023
specimens of 31 species were collected. These 31 species represented 11 families
and 20 genera.
Annotated Species List; ~-
Lepisosteidae (gars)
Lepisosteus osseus (longnose gar). This species is very dominant in some
sections of the lower part of the Clear Fork of the Brazos River. Some stretches
of stream in the lower area have apparently been practically denuded of small fish
by this species. The gars in those sections were observed to be rather poor and on
the average, weighed only one pound. In one particular netting location in the
lower river, gars were so active and perhaps so ravenous that there were approximately
20 of them in the gill net before the survey crew had it completely set out. There
were no gar taken in the upper reaches of the watershed and none collected from
lakes in either regions. Thus, considering the whole river, its tributaries, and
the lakes on the watershed, gar accounted for only 2.45 percent of the total fish
netted.
Clupeidae (herrings)
Dorosoma cepedianum (gizzard shad}. This species was aboundant in both
netting and seining collections composing 9.42 percent of the total seining sample
and 23.95 percent of the total netting sample. This was the highest percentage,
by number, of any species taken by netting. The river, itself, was particularly
heavily infested with this species, with over 35 percent of the fish taken from
the river being shad. They were large averaging over 10 ounces, while the shad
taken from the lakes averaged only 2.5 ounces.
Catostomidae (suckers and buffalofishes)
Ictiobus bubalus (smallmouth buffalo). Most netting stations in the river
yielded this species, but they were not as prevalent in the lakes. This species has
a high commercial value and is netted commercially in Lake Fort Phantom Hill. The
difficulty of access and netting in the holes in the river, where the majority of
this species exist, prevents a more wide-scale commercial utilization of these fish
--- Page 7 ---
from the Clear Fork of the Brazos.
Carpiodes carpio (river carpsucker). This is the dominant sucker in nearly
all West Texas waters. They were taken both by net and seine and were widely dis-
tributed throughout the watershed. The presence of this species constitutes a
serious fishery problem in some lakes on the Clear Fork of the Brazos River drainage,
especially since no utilization of the species by either man or fish has been ob-
served. .
Cyprinidae (shiners and minnows)
Cyprinus carpio (carp). This species is sub-dominant to the river carpsucker
but does constitute a fishery problem in lakes where it occurs. Carp have more
utility than river carpsuckers and they are becoming more and more fished for in
many West Texas lakes because of their large size, tremendous strength, and willingness
to fight when caught. ,
Notemigonus crysoleucas (golden shiner). Although this species was taken by
net and seine, it was taken only from lakes. It is not believed to be native in
the Clear Fork of the Brazos River, or its watershed, but is known to have been
introduced as a forage fish by the state fish hatcheries,
Notropis lutrensis (redhorse shiner). This is the dominant shiner in the Clear
Fork of the Brazos River and its tributaries. They constituted over 44 percent of
the fish taken by seining for the whole watershed. These minnows are particularly
abundant in the sporadic, intermittent streams of the upper part of the Clear Fork.
Notropis volucellus (mimic shiner). Only nine specimans of this species were
collected from the complete watershed. They were collected from a number of different
types of habitats, but were always in very much of a minority. Five were collected
from lakes and four were collected from the river and they were taken from both the
upper and lower watersheds.
Notropis buchanani (ghédst shiner). Only two specimens of this species were
collected. These collections indicated that the fish prefers running, muddy waters.
Pimephales vigilax (parrot minnow). Nearly all of the 149 individuals of
this species collected were taken in the bigger waters of the middle and lower
reaches of the river. Some localities in the lower river were saturated with these
minnows. While taking a collection from the Pitt Taylor Ranch, in the lower river,
thousands of these minnows were observed trying to swim up stream into the water
pouring over a small dam.
Pimephales promelas (fathead minnow). This species was found in abundance in
the upper reaches of the river and appears to be dominant over the parrot minnow
in this area while the trend is apparently reversed in the lower river.
Ameiuridae (freshwater catfishes)
Ictalurus punctatus (channel catfish). Only occasional specimens of this fish
were obtained by seining and netting in the river and its tributaries. The species
was very abundant in netting collections taken from the lakes and composed almost
23 percent of the number and almost 4% percent of the weight of the total netting
--- Page 8 ---
sample. This fish is very much sought after by West Texas anglers and is frequently
stocked from the state fish hatcheries.
Ictalurus melas (black bullhead). This species was taken by net and seine
from both the river and the lakes. It appears to be more abundant in some of the
smaller lakes, which apparently have no flathead catfish, than in any other waters.
Ictalurus natalis (yellow bullhead). This species appears to be more prevalent
in the river than in the lakes and was very much outnumbered in the fish collections
taken from the lakes by the black bullhead.
Pylodictus olivaris (flathead catfish). This very desirable food fish is much
sought after by anglers and apparently serves as an effective bullhead control in
lakes where it occurs. Only four specimens of this species were collected, but this
is attributed to a fault in the means of sampling (ie. the small meshes of the nets
used are not effective in capturing this species) and to the probability that these
fish lie on the bottom in a lethargic state for long periods of time. These fish are
known to be taken by anglers in several of the lakes on the Clear Fork of the Brazos
River watershed where they were not taken in the fish collections.
Cyprinodontidae (killifishes and topminnows )
Fundulus notatus (blackstripe topminnow). The only locality in which this
topminnow was seined was a tributary of the lower part of the river.
Fundulus kansae (plains killifish). This species was collected from the Old
Hamlin City Lake which contains large amounts of chlorides which are believed to be
the results of nearby oil wells. The killifish was not taken from any other locality.
Cyprinodon rubrofluviatilis (Red River pupfish). This species appears to be
the dominant fish in the Old Hamlin City Lake where the water is too salty for most
other species and was collected only from this locality.
Poecilliidae (mosquitofishes)
Gambusia affinis (mosquitofish). The mosquitofish is common in backwater
sloughs and quiet pools throughout the watershed. They were the second most common
fish in the seining collections, and are considered to be very desirable to man
because of their practice of eating mosquitos.
Serranidae (basses)
Rocecus chrysops (white bass). This species is not indigenous to the Clear
Fork, but has been introduced in some of the lakes on the watershed. Although
not many of these fish were collected, Fort Phantom Hill Lake is known to have a
large population.
Centrarchidae (black basses and sunfishes)
Micropterus salmoides (largemouth bass). The evasive nature of these fish
makes them difficult to capture in nets and seines. It is therefore difficult to
arrive at an accurate estimate of their occurrence. The data collected would
--- Page 9 ---
indicate, however, that they are much more common in some of the lakes than they
are in the river.
Chaenobryttus gulosus (warmouth bass). One fish of this species was taken
from Lake Daniels on the lower Clear Fork watershed. These fish are often stocked
by the state fish hatcheries.
Lepomis cyanellus (green sunfish). This sunfish is common throughout the
watershed and is a desirable species to the angler when it attains a reasonable size.
However, very few of these sunfish collected were large enough to be fished for and
some individuals, only 2-inches long, were full grow, sexually ripe, fish.
Lepomis microlophus (redear sunfish). This is one sunfish that generally
attains a desirable size in West Texas waters. Only a few individuals of this species
were collected. These were probably present because of hatchery stocking and very
likely not native to the stream.
Lepomis macrochirus (bluegill). This is the dominant sunfish in the Clear
Fork of the Brazos drainage and was abundant both in lakes and in the river. None
of these fish were of a desirable size, probably due to overpopulation. Some
individuals were sexually mature at a length of two inches.
Lepomis humilis (orangespotted sunfish). Even under ideal conditions these
sunfish do not attain a very desirable size, and all of the individuals collected
from the Clear Fork were extremely small. This species is apparently subordinate to
the other native sunfish.
Lepomis megalotis (longear sunfish). This is one of the more dominant sunfish
species in the Clear Fork. They appear to prefer running stream areas, but were
very abundant in the upper reaches of the river whether the water was running or
was standing in pools. These fish, like the other species of sunfish, appeared
to be stunted. ,
Pomoxis annularis (white crappie). Practically all the bigger waters of the
Clear Fork and its watershed contained white crappie. They were particularly
abundant in the lakes. However, not many were collected that were a desirable size.
Pomoxis nigromaculatus (black crappie). Two specimens of this species were
taken from Lake Sweetwater. They were very large crappie and in very good condition.
It is nearly certain, however, that these fish were stocked in that reservoir and
are not indigenous to the watershed.
Percidae (perches and darters )
Percina caprodes (logperch}. This apparently unimportant species was collected
only from Lake Trammell on the Clear Fork of the Brazos River watershed. Since
this fish is hard to collect by seining, it is possible that this was present in
some of the other seining localities but missed,
Sciaenidae (croakers, drum, and weakfishes)
Aplodinotus grunniens (freshwater drum). This species was taken from only
--- Page 10 ---
two lakes on the watershed. These fish are apparently hard to sample by the use of
seines and gill nets as very few have been collected in lakes that are thought to
have relatively high populations.

%* This chart was compiled on an arbitrary basis with the following factors
taken into consideration.
(1) percent of each species represented in the total seining collections
from the upper or lower watersheds
(2) the number of locations where the species was collected
** (1) consideration must be given to the fact that some species are more
difficult to collect by seining than are others when analyzing the
data herein given
(2) consideration must be given to the fact that the shallow waters of
the upper watershed was more conducive to seining than were the deep
waters of the lower watershed and for that reason some species may
have not been collected in the lower watershed that were, in reality,
present.
(3) consideration must be given to the fact that the Clear Fork of the
Brazos River's watershed was divided into upper and lower regions on
a sharp line selected on a more or less arbitrary basis and that, in
reality, the physical, chemical, and biological characteristics of
the upper and lower regions overlap.
