Item Analysis of Instream Flows for the Lower Brazos River - Hydrology, Hydraulics, and Fish Habitat Utilization(Surface Water Resources Division, Texas Water Development Board, 2004-06) Osting, Tim; Mathews, Ray; Austin, BarneyItem Analysis of Instream Flows for the Sulphur River: Hydrology, Hydraulics and Fish Habitat Utilization(Surface Water Resources Division, Texas Water Development Board, 2004-07) Osting, Tim; Mathews, Ray; Austin, BarneyItem An Annotated Checklist of the Freshwater Fishes of Texas, with Keys to Identification of Species, 2nd Edition(Texas Academy of Science, 2008-07) Hubbs, Clark; Edwards, Robert J.; Garrett, Gary P.Forty-nine families and 268 species of fishes are known to inhabit the freshwaters of Texas. We report on the distribution and status of these fishes and provide a key to their identification. Of the native fishes originally found in Texas, five taxa, Cyprinella lutrensis blairi (Maravillas red shiner), Notropis orca (phantom shiner), N. simus simus (Rio Grande bluntnose shiner), Gambusia amistadensis (Amistad gambusia) and G. georgei (San Marcos gambusia) are apparently extinct, and four, Hybognathus amarus (Rio Grande silvery minnow), Notropis simus pecosensis (Pecos bluntnose shiner), Oncorhynchus clarki virginalis (Rio Grande cutthroat trout) and Gambusia senilis (blotched gambusia) appear to be extirpated from the state. Over 40 percent of the remaining primary freshwater species are of conservation concern and in some need of protection.Item Baseline Fish Collections - Lower Sabine River Priority Instream Flow Study(Texas Water Development Board, 2007-02-28) Sabine River Authority of Texas; Texas Commission on Environmental Quality; Texas Parks and Wildlife Department; Texas Water Development BoardPriority instream flow studies under the Texas Instream Flow Program (TIFP) were selected based on potential or planned water development projects, water rights permitting issues, and other factors. A study on the lower Sabine River was prioritized1 based on the potential for water transfers within the Sabine Basin, proposed inter-basin water transfer projects, and Federal Energy Regulatory Commission hydropower relicensing of the Toledo Bend Dam. The Lower Sabine River Priority Instream Flow Study was initiated in September 2004 with the Reconnaissance and Information Evaluation2 phase – the first step of a study under the TIFP. The purpose of the Reconnaissance and Information Evaluation phase, according to the TIFP Technical Overview, is to compile, review, and geo-reference available studies and data, identify historic and current conditions, identify significant issues and concerns, and conduct preliminary field surveys and analysis. During reconnaissance, the Sabine River Authority of Texas (SRA-TX) compiled a bibliography of information related to the Sabine River from the Toledo Bend Dam to the mouth of the Sabine River at the north end of Sabine Lake. Biological data compiled during reconnaissance included benthic macro-invertebrate and fish data sets from rapid bio-assessments of many of the main tributary streams of the Sabine River in Texas through a basin-wide effort that began in 1993 to characterize the biological community of the priority subwatersheds of the Sabine River Basin. Biological data has also been collected from the main stem of the river for specific studies but not as a basin-wide effort. Most main stem biological data is from a benthic macro-invertebrate monitoring contract with a local industry from 1989-1992 and from some Texas Commission on Environmental Quality (TCEQ) fish collection work near Anacoco Bayou in 2003. An analysis of the bibliography compiled during reconnaissance revealed a lack of recent biological data for the main stem of the lower Sabine River. In order to have a more complete biological set, a study under Texas Water Development Board (TWDB) Contract No. 0604830567 between the TWDB and the SRA-TX was funded by a TWDB Research and Planning Fund Research Grant. Collections and habitat assessments were made at eight sites beginning May 2006 through September 2006 by staff from Texas Parks and Wildlife Department, TCEQ, TWDB, and SRATX. The magnitude of the effect of Hurricane Rita and the drought of early spring 2006 on the diversity and population of species collected has not yet been assessed. Additional sampling is proposed to mitigate any seasonal or equipment bias as well as to further assess the effects of the hurricane and the drought.Item Distributional Survey and Habitat Utilization of Freshwater Mussels(Texas Water Development Board, 2008-01) Karatayev, Alexander; Burlakova, LyubovItem East Texas Mussel Survey(2007-11-09) Karatayev, Alexander; Burlakova, LyubovField surveys of freshwater mussels (family Unionidae) were conducted at 49 sites in 22 waterbodies (4 rivers, 7 reservoirs, and 11 streams) within the Red, Trinity, Neches, and Sabine drainage basins using standard qualitative and quantitative methods. Depth, dominant substrates, GPS coordinates, and water chemistry were recorded at each site. Abundant and diverse mussel beds were located in the Sulphur, Angelina, and Neches rivers. These sites can be used for future monitoring. Several waterbodies were surveyed for the first time (i.e. Cooper Reservoir, Wright Patman Reservoir, Houston County Reservoir, Striker Reservoir, and lower Sabine River tributaries). Extreme rainfall and flooding in 2007 prevented successful sampling of several sites. Mussel populations in a number of waterbodies (i.e. Sulphur River, Cooper Reservoir, Houston County Reservoir, B.A. Steinhagen Reservoir, Toledo Bend Reservoir) were severely damaged during previous droughts or drawdowns. Several sites with abundant and diverse unionid assemblages were suggested for monitoring, conservation, and recovery plans. This survey will provide data necessary for successful management and conservation of unionids in East Texas rivers and reservoirs.Item Existing Reservoir and Stream Management Recommendations - Statewide Minimum Streamflow Recommendations(Texas Parks and Wildlife Department, 1979-10-16) Bounds, Robert L.; Lyons, Barry W.Literature on assessing streamflow needs was reviewed. Recommendations from two of the methodologies described were combined to develop minimum flows needed to maintain Texas stream fisheries. These flows were 40 percent of the median monthly flows October-February and 60 percent March-September. To validate these flows, a field evaluation was conducted on the Guadalupe River below Canyon Reservoir. Results suggest that the above minimum flows are valid for Texas stream fisheries.Item Fish Species Common to Texas Major River Basins(Texas Parks and Wildlife Department, 1998) River Studies Program, Texas Parks and Wildlife DepartmentSpecies list was compiled by the TPWD - River Studies Program Personnel using Hubbs et al. (1991) and Lee et al. (1980). Feeding groups and tolerance ratings are from Linam and Kleinsasser (1998). Feeding group designations are: IF - invertivore, P - piscivore, O - omnivore, and H - herbivore. Tolerance designations are: T - tolerant, I - intolerant. Species without a tolerance designation are considered intermediate.Item Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico(US IBWC, 0000-00-00) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1950 with Maximums, Minimus, and Normals(US IBWC, 1950) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1951 with Maximums, Minimus, and Normals(US IBWC, 1951) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1952 with Maximums, Minimus, and Normals(US IBWC, 1952) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1953 with Maximums, Minimus, and Normals(US IBWC, 1953) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1954 with Maximums, Minimus, and Normals(US IBWC, 1954) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1955 with Maximums, Minimus, and Normals(US IBWC, 1955) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1956 with Maximums, Minimus, and Normals(US IBWC, 1956) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1957 with Maximums, Minimus, and Normals(US IBWC, 1957) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1958(US IBWC, 1958) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1959(US IBWC, 1959) International Boundary and Water CommissionItem Flow of the Rio Grande and Related Data: From Elephant Butte Dam, New Mexico to the Gulf of Mexico 1960(US IBWC, 1960) International Boundary and Water Commission
