Jab Completion Report State of TEXAS Project No: F-huRw6 Name: Fisheries Investigation and Survexs of the Waters of Region -B. Jet No: Bm25 Title: Basic Survey and Inventory of Those Portions of the Brazos River Watershed, Including the Leonz Bosgue, Nolan and J Navasota Rivers Situated in Palo Pinto, Parkerz Erath, Johnson, Hoodz Somervell, Coryell, McLennanz Hill, Robertsonz and Leon Counties. This survey to exclude Lakes Possum Kingdomz Whitney and Waco. Period Covered: November 1, 1958 - October 31, 1959 Abstract: Twenty collection stations were established on the Brazos River Watershed situated Tithin the counties that make up Region h-B: Fifteen seine collections were made along Jith seven gill net and one rotenone collection, A total of 3,890 fish specimens representing 10 families, 13 genera and 2h species was taken: The streams that make up this portion of the Brazos River Watershed are generally clear with the exception of the leon and Navasota Rivers, The Brazos, Bosqne, and Nolan Rivers have sand, gravel, and rock bottoms while the Navasota and Leon have clay bottomso Chemical analyses of the Brazos River water were made by the United States Geological Survey at stations established below the Possum Kingdom and Whitney Dams: Data from these stations do not indicate that the chemical content of the water is a limiting factor in fish productiono Little aquatic vegetation is to be found in these streams because of the scouring effect of floods caused by heavy rains on the watershed: Objectives: To gather fundamental data on the above waters in regard to their physical, chemical and biological aspects: To determine the distribution of fish species present, their relative abundance and the ecological factors influencing their distribution: Techniques: Fish were collected at 20 stations on the watershed (Plate 1}. Seine collections were made with minnow seines at 15 of these stations, while gill net collections were made at 7 stations: One rotenone collection was made, The fish taken by minnow seine were preserved in 10 percent formalin and trans— ported to the laboratory for identification and enumeration. Specimens taken by gill net were identified in the field where lengths and weights were recorded. The United States Geological Survey made the monthly analyses of Brazos River water available for this report. Analyses were made at two points in the area. These points were below the Possum Kingdom Dam and below the Whitney Dam. These reports were examined to determine any factors that might influence fish life. History: A survey of the Brazos River, between Possum Kingdom Dam and Lake Whitney, to— gether with the Bosque River and the Leon River in Comanche, Hamilton and Coryell Counties was attempted_in 1953 and 195h. The results of this survey were reported in thuRwl, JOb B-6. The drouth conditions at that time reduced the rainfall to a point where only a few streams contained water. The water was reduced to small pools except in the Brazos where power production at the Possum Kingdom Dam resulted in an intermit— tent flow. Physical Characteristics: The Brazos River leaves Possum Kingdom Lake in a broad stream that has a sand and gravel bottom interspersed with boulders. This type of bottom gradually changes until the bottom is largely sand. The banks are alternately steep rock cliffs and shallow sloping sand or clay banks. The upper part of the watershed is generally clear but as the stream progresses toward the Gulf oerexico more silt is acquired until the water becomes murky. This is not a muddy stream except for a short period following heavy rains. The Bosque River is much like the Brazos in that it is essentially a clear stream. The bottom is largely gravel and sand with numerous stretches of rock hardpan. The Basque flows into the Brazos at waco where a dam impounds Lake waco for a municipal water supply (Plate 1). The Leon River is a narrow, fairly deep stream that flows through cultivated lands and is generally murky becoming muddy after rains and clearing rather slowly. This stream flows into the Little River which then joins the Brazos near Hearne, Robertson County, Texas. A dam near the juncture of the Leon with Cowhouse Creek forms the Belton Reservoir, a large impoundment (Plate 1). The Nolan River drains the farmland of Johnson County and flows into the Brazos at the upper end of Lake Whitney. This stream is muddy after rains but clears rather quickly since the lower part is send bottomed and flows through land that is largely used for grazing. The margins vary from shallow, sloping, grass covered clay banks to high rocky cliffs with the former predominating. Entering the Brazos River near Navasota, Texas, is the Navasota River. This is a narrow, fairly deep stream that flows through Limestone County and drains parts of Freestone, Robertson and Leon Counties. This stream is generally murky as it flows through clay soils that are intensively cultivated and picks up much silt with each rain. A dam, at Mexia, near the upper end of the Navasota forms Ft. Parker State Park Lake which has a fairly low dam from which water is released to provide a municipal water supply for the town of Groesbeck. Chemical Characteristics: The United States Geological Survey has established sampling stations on the Brazos below the Possum Kingdom Dam and the Whitney Dam. Water samples from these stations are analyzed monthly and the results made available for this report. (Tables 5 and 6). There is some variation in the chemical composition of the water in the Brazos River at the two sample stations but these are not excessive. The water below the Possum Kingdom Dam generally contains more parts-perwmillion of each element or compound than the water below the Whitney Dam. This difference is not believed to be sufficient to have an appreciative effect on the fish present. The Brazos River watershed is not subject to heavy industrial or sewage pollution in the area covered by this survey. Waco is the largest city in this area and no pollution has been noted or reported from this source, since the construction of a new sewage disposal plant some years ago. There is some saltwater from oil operations as well as from natural salt deposits but the majority of these are located above Possum Kingdom Lake and probably account for the majority of the difference in the chemical analysis of water from the two sampling stations. Aquatic Plants: There is little or no aquatic vegetation in this watershed since these streams re subject to the securing effect of intense floods. The flooding together with the release of water from the dams on the Brazos and Leon Rivers tend to prevent the growth of the large aquatic plants. Those streams that are less subject to flooding tend to be murky during a great portion of the year which tends to prevent the growth of all types of aquatic vegetation. Results of Fish Collections: Seining collections were made at 15 stations, gill net collections were made at 7 stations, and one rotenone collection was made (Table h). The results of these collections are given in Tables 2 and 3. A total of 3,890 fish specimens representing 2% species and 13 genera were taken (Table l). Seine collections took 2,093 specimens of 9 genera and 1h species. Gill nets accounted for 1,160 specimens of 12 genera and 19 species. The single rotenone collection took 637 specimens representing 6 genera and 8 species. ANNOTATED CHECKLIST Lepisosteidae (gar) Lepisosteus productus: The spotted gar was collected at four of the seven gill net stations. They appear to bother the fisherman more than they do the game fish. They are blamed for acts that are difficult to prove. They steal baits from his hook but little proof has been offered as to their damage to the game fish population. Lepisosteus osseus: The longnose gar is often called the needle gar or fish gar and is thought by many fishermen to be responsible for lowered populations and poor take of game fish. This species appeared in five of the seven gill net collections and like the spotted gar appears to be blamed for misdeeds that have not been proven. Clupeidae (shad) Dorosoma cepedianum: The gizzard shad was taken in four net and four seine collections but were sufficiently numerous in those to contribute 1,797 specimens to the total specimens taken. This number was further augmented by #00 which were taken in the rotenone collection for a total of 2,197 or 56.5 percent. This species inhabits the majority of the watershed but is more prevalent in lakes and in the deeper pools of the stream. Catostomidae (suckers and buffalo fish) Ictiobus bubalus: Smallmouth buffalo are found throughout the watershed but during this survey they were taken at only four net stations. 'This is the most prominent of the commercial species in this area and supports the contract netting in Lakes Waco, Whitney, Possum Kingdom and Ft. Parker. Carpiodes carpio: The carpsucker is found in the same waters as the buffalo but has little value from a commercial or food standpoint. This species is quite prolific and, when present in large numbers, tends to crowd out the more desirable fish. Their value as forage appears to be limited to the short period when they are small. Cyprinidae (shiners and minnows) Cyprinus carpio: The carp is widely distributed in the Brazos River and its tributes ries. This species is badly underrated by the angler and when properly prepared is an excellent table fish. Carp were taken at three gill net stations and 10 were taken in the rotenone collection. The carp is considered to be one of the better baits for flathead catfish and is suitable for pond culture. Notropis venustus: The spottail shiner was taken at 8 seine stations and is one of the most prominent of the bait and forage species. Notropis lutrensis: The red shiner or redhorse Shiner is the most widely distributed of the forage species. It was present in all but two of the seine collections. This species is sought after by minnow dealers and finds a ready sale. Its color and ability to live on the hook, as bait, makes the red shiner a favorite with the angler. Notropis volucelluss The mimic shiner was taken at only one seine station. This was in the Newasota River below Ft. Parker Dam. The species is of little significance since they are small and, on the basis of seining collections made during the study, does not appear to be very widely distributed. Ameiuridae (freshwater catfishes) lctalurus punctatus: Channel catfish appeared in all of gill net collections but were not taken in any of the seine samples. They are present in the streams and appear to stay in the deeper pools making them difficult to take with seines. This is the most popular of the commercial species and supports a large trotline fishery in the lower part of the Brazos River. Bait fishermen prize the channel catfish highly as a food and sport fish. They are distributed throughout the streams of the watershed. Ictalurus males: The black bullhead is of little importance in the majority of the Brazos watershed. It was taken in only two seine collections and one net collection. Ictalurus natalis: Yellow'bullheads were taken at two gill net stations and appear to be of little importance. None were taken in seine samples. Gyprinodontidae (killifishes and topminnows) Fundulus notatus: Blackstripe topminnows have been observed in much of the Brazos watershed but were taken at only two seine stations. They have little value as a forage or bait species. Fundulus kansae: The plains killifish was taken at only one seine station. This was a shallow, rockmbottom riffle in the Palnxy River, near Glen Rose. Poeciliidae (mosquito fishes) Gambusia affinis: This species is found in all parts of the watershed despite the fact that mosquito fish were collected at only six of the seine stations. The gambusia is of little value as a forage species and seldom if ever used as a bait minnow. The value of this species appears to be in the field of mosquito control. Aquatic insect larvae occupy a high place in the food items consumed by them. Serranidae (basses) Roccus chrysops: The white bass was introduced into the Brazos watershed after the construction of Possum Kingdom Lake and has become well established. This species if found in abundance below the Possum Kingdom and Lake Whitney Dams. They were not taken in seine samples and appeared in only three net samples despite the fact that many are taken by hook and line. White bass are important to the fishery of the region since .hey may be taken on a variety of baits at almost any time during the year. A possible disadvantage lies in their reproductive capacity which, under favorable conditions, allows them to become overabundant. They are of value as a control on gissard shad which appears to be the main source of food for adult white bass. Centrarchidae (black basses and sunfishes) Micropterus salmoides: largemouth black bass are the most popular of the sport fishes in the Brazos watershed. They attract artificial lure and natural bait fishermen alike. This species is known to be present in all parts of the watershed but were absent from a majority of the collections. The float fishing that is done along the Brazos River is due almost entirely to the presence of largemouth bass in the rocky pools between Possum Kingdom Dam and the upper end of Lake Whitney. Lepomis cyanellusz The green sunfish is locally known as the goggle-eye and is cone sidered one of the favorite targets of the fly fisherman. This species is known to inhabit the entire watershed despite the fact that they were taken at only one seine and two gill net stations. Lepomis microlthuss Redear sunfish are among the fish most desired by the worm fisherman. This species is game and takes flies or natural baits readily. They tend to congregate in certain areas of lakes and streams which allows the fisherman to continue to make good catches once he locates the bed. The-redesr:is not so prolific as some of the other sunfishes and is not so likely to overpopulate the area. Lepomis macrochirusg Bluegill sunfish have long been considered the summer companion of the small boy. They are very prolific and almost permanently hungry. This species takes worms, flies and insects with equal favor. They may be taken in great numbers at almost any time during the warmer months. They do serve as food for other more desirable fish, but their rate of reproduction is so high that they tInd to over populate and crowd out the more desirable species. The bluegill is found in all parts of the watershed and was taken in all but five of the seine and net samples, and were the second most abundant species in the rotenone collection. Lepomis humilis: Orangespotted sunfish were found at only one collection station on the Brazos River watershed. This is a small species and appears to be of little ime portance except as a forage fish in locations where the population is sufficiently dense to be of value. Lepomis auritus: The yellowbelly sunfish has been introduced by fish hatcheries into almost all the lakes and streams of the Brazos watershed. It is not so prolific as the bluegill and attains a larger size than the longeer and, despite the small size of the mouth, it is readily taken on flies. In recent years the yellowbelly sunfish has come to occupy a prominent place in the catch of the worm and fly fisherman of the area where it is often confused with both the bluegill and longear. Lepomis megalotis: Longear sunfish are found in all parts of the Brazos watershed but were collected at only two net stations. This highly colored sunfish rises readily to small flies but seldom attains sufficient size to be of interest to the fisherman. Their value as a forage fish is offset by their prolific reproduction which tends to overcrowd an area. Pomoxis annularis: White crappie are found throughout the watershed. They were taken at 5 net stations and at only one seine station. Crappie are taken from the deeper pools throughout the watershed and are abundant in the majority of the lakes. Sciaenidae (croskers and drums) Aplodinotus grunniens: The freshwater drum is present throughout the watershed but was collected in only one seine sample and three gill net samples. This species is generally small and is not important in the fishery. The larger specimens are usuw ally taken from the lakes but in the lower portion of the Brazos an occasional large drum is caught.
