TPWD 1954 F-4-R-1 #79: Inventory of species present in those portions of the Brazos River and tributaries lying between Possum Kingdom Lake and Lake Whitney

--- Page 1 --- STATE _ Texas PROJECT NO. F-4-R-1, dob B-6 PERIOD June 1, 1954 - May 31, 1954 Job Completion Report by Leonard D. Lamb Project Leader Robert N. Hambric Assistant Project Leader TITLE Inventory of species present in those portions of the Brazos River and tributaries lying between Possum Kingdom Lake and Lake Whitney and in- cluded in the following counties; Palo Pinto, Parker, Hood, Somervell and Johnson. OBJECTIVES To determine the distribution of species present, their relative abundance and the factors influencing their distribution. METHODS Seine stations were astablished on the Brazos and tributaries be- tween Possum Kingdom and Lake Whitney and were visited when water conditions would permit. (Figure 1). Specimens collected were preserved in 10% formalin and transport- ed bo the laboratory for identification and tabulation. These specimens have been retained for further and more detailed study should time and per- sonnel permit. Lack of chemical equipment until the last few weeks of the pro- iod prevented the determination of data pertaining to the dissolved esent in the water. RESULTS The collections from the Brazos River watershed total 882 speci- mens, representing 18 species, 12 genera and 7 families. (Table 1) The plains red shiner (Notropis lutrensis) was most abundant in the collections {58,28%}, followed by blacktail shiner, (Notropis venustus (16.67%), bluegill sunfish (Lepomis macrochirus), 8.05%, river carpsucker (Carpiodes carpio) © 44% and black stripe topminnow (Pundulus notatus) 3.51% in that order. The remaining 13 species make up a total of 8.05% of the collection. (Table 2.) This watershed is situated in both the West Cross Timbers and the Grand Prairie ecological regions but there is little difference in the type of vegetation and land use in these separate areas. The streams are largely sand and gravel bottomed with variable banks that may be shallow and sloping at one point and change abruptly to a sheer faced rock cliff many feet in height. The runoff is rapid and drouth conditions for the past three years --- Page 2 --- Qa ha kept the stream flow to a minimum in all but the Brazos where the oper- ation of the hydro-electric generators in the Possum Kingdom Dam produce a variable flow. This flow may almost fluctuate from flood stage to practi- cally no flow, depending upon the power production needs. The uncertainty of flow on the Brazos, together with the almost total absence of water in the tributary streams during the greater part of the project period made collections rather inadequate. The rains of April and May provided water for the tributaries but also filled Possum Kingdom Lake to a point where constant release of water prevented collections except in the backwater on the edge of the river. The collections show a slight difference between the ecological regions. The species collected only from the West Cross Timbers were small- mouth buffalo (Ictiobus bubalus) and ribbon shiner (Notropis fumeus) while those collected only from the Grand Prairie were; river carpsucker (Carp- iodes carpio), Texas gray redhorse (Moxostoma congestum), palid shiner (Notropis amnis), silvery minnow (Hybognathus nuchalis), yellow bullhead (Ameiurus natalis), largemouth bass (Micropterus salmoides), green sunfish (Lepomis cyanellus), spotted sunfish (Lepomis punctatus) and longear sunfish (Lepomis megalotis). The difference in species may be due to the inability to obtain an adequate sample because of water conditions. The locations from the Grand Prairie region were made in three tributary streams: Squaw Creek, Paluxy River and Fall Creek. There were no collections made from the Brazos River in this area because of the swift current and the absence of backwater. The collections from the West Cross Timbers Region were made in the backwater pools on the Brazos River since there was no water in the tributaries that could be reached. The use of rotenone was considered to be impractical since there are no accessible pools and it was considered unwise to attempt this method in a stream with considerable flow. Data collected from a representative station is included in the following data sheet and is typical of the data col_ected from all the stations. SUMMARY l. Collections were established on the Brazos River and tributar- s between Possum Kingdom Lake and Lake Whitney for the purpose of collec- es ing date regarding the species present. et 5 2. A total of 822 specimens representing 18 species, 12 genera and 7 families were collected. plains red shiner (5%.28%), blacktail shiner (16.67%), bluegill sunfish (8.05%), river carpsucker (5.44%) and blackstripe topminnow (3.51%). 3. Five gpecies made up 91.95% of the total collection. They were: - h, This watershed is located in two ecological regions. The upper part is in the West Cross Timbers and the lower portion is in the Grand Prairie. There is little difference in the vegetation types and type of land use found in the two regions. 5. Drouth conditions plus the uncertainty of releases of water from the dam at Possum Kingdom Lake prevent adequate sampling of the watershed and cause variations in type of collections made. --- Page 3 --- FISE CARD ry Coll.
