These data represent reproductive ecology characteristics for 4 species of mature female turtles captured at Elephant Butte Reservoir on the Rio Grande River in New Mexico, during two field survey periods in June 2012 and 2013. Data were collected on female reproductive ecology including clutch size, egg size, timing of egg production, and the percentage of reproductive females using X-radiography. The purpose of these data are to add to the deficient information on the reproductive ecology of four turtle species at the Elephant Butte Reservoir on the Rio Grande and Black River in New Mexico. Data contained in this worksheet were analyzed to determine clutch and egg sizes for four native species of turtles (Apalone...
Small-bodied, riverine minnows that historically characterized fish assemblages of Great Plains rivers in North America have declined because of river fragmentation, dewatering, river channel degradation, river salinization and nonnative species introductions. The Pecos bluntnose shiner Notropis simus pecosensis, a member of this guild, persists in one segment of the Pecos River, New Mexico, USA. We characterized habitat associations for the species at two spatial scales. In general, N. s. pecosensis associated with fluvial habitats, but velocity association depended on body size, with larger individuals using swifter habitats. All N. s. pecosensis associated with relatively low depths (3–51 cm), which were most...

This part of the data release contains historical streamflow data compiled from the literature and evaporation loss estimates used in the streamflow gain loss equation. These digital data accompany Houston, N.A., Thomas, J.V., Ging, P.B., Teeple, A.P., Pedraza, D.E., and Wallace, D.S., 2019, Pecos River Basin Salinity Assessment, Santa Rosa Lake, New Mexico to the Confluence of the Pecos River and the Rio Grande, Texas,2015: U.S. Geological Survey Scientific Investigations Report 2019-5071, https://doi.org/10.3133/sir20195071.

This Data Release contains various types of hydrologic and geologic data from the Pecos River Basin during1900–2015, including water-quality data compiled and synthesized from various sources (including data from water-quality samples collected by the USGS in 2015 from 26 sites), streamflow gain-loss data collected by the USGS in 2015 and historical streamflow gain-loss data compiled from the literature, the horizontal extent of and depth to the base of the 16 geologic and hydrogeologic units that underlie the study area, and geospatial data collected by the USGS. The data were used to complete a detailed salinity assessment of the Pecos River from Santa Rosa Lake, New Mexico to the Confluence of the Pecos River...

Our approach will include sampling a wide range of habitats and environmental conditions throughout the middle and lower Pecos River basin, across an 18 month time-span to account for seasonal and phenological events. We will utilize a suite of univariate and multivariate statistical techniques to relate occurrence and density of golden alga to environmental factors and other co-occurring organisms. The proposed research will benefit managers of the Pecos River, of its associated reservoirs and unique habitats (sinkholes on the Bottomless Lakes State Park and Bitter Lakes National Wildlife Refuge), and of its resident aquatic biota by identifying specific water quality attributes that promote golden alga bloom development...

This part of the Data Release contains the water-quality data compiled and synthesized from various sources(including data from water-quality samples collected by the USGS in 2015 from 26 sites). This collection includes three main tables that contain (1) the list of site locations that water-quality data were collected, and information about those sites, such as the spatial coordinates of a well (Site_information); (2)the list of samples that were collected, and information about those samples, such as the date the sample was collected (Sample_information); and (3) the results of the measured constituent, and information about the result such as amount of concentration measured in a constituent(Water_quality_results)....

REPORT PROJECT BACKGROUND: Golden alga (Prymnesium parvum) is a harmful algal species that is primarily found in marine ecosystems but is also present and invasive in brackish inland waters. The first documented bloom of golden alga in the United States occurred in the Pecos River in 1985. This species has since invaded other water bodies in the Pecos River basin (e.g. sinkhole habitats, reservoirs) and has been reported in at least 23 U.S. states. Toxins produced by golden alga can be lethal to fishes, bivalves, crayfish, and gilled amphibians. The ecological and economical impacts of golden alga blooms have been severe. Recent research suggests that the frequency and severity of golden alga blooms will increase...

This part of the data release contains geospatial data collected and compiled during the Pecos River Basin salinity assessment of the Pecos River Basin from Santa Rosa Lake in New Mexico to the confluence of the Pecos River and the Rio Grande in Texas. Raster representations of horizontal extent, and depth below land surface to the base of sixteen Quaternary through Permian aged geologic units that underlie the Pecos River Basin are provided in image format. These units include: the San Andres Limestone; the Artesia Group which includes the Grayburg, Queen, Seven Rivers, Yates, and Tansill Formations; Capitan Limestone; Castile, Salado, and Rustler Formations; the Dewey Lake Redbeds; the Dockum Group (divided into...

This part of the data release contains the geospatial data collected by the USGS during the Pecos River salinity assessment. The data includes a feature class of the study area boundary and the Pecos River Basin boundary, the picks that were used to develop the depth to the base of the 16 geologic units, a feature class of springs, seeps and sinkholes compiled in the study area, a feature class of the USGS streamflow-gaging stations locations in the study area, a feature class of the locations of the saltwater disposal wells in the study area, and a feature class of areas of interest with respect to salinity. These digital data accompany Houston, N.A., Thomas, J.V., Ging, P.B., Teeple, A.P., Pedraza, D.E., and...
