These data represent capture histories for humpback chub (Gila cypha) that spawn in the Little Colorado River (LCR) from 2009-2017. Capture histories pertain to size class (<150mm total length [TL], 150-199mm TL, 200-249mm TL, and >250mm TL) and spatial location (the juvenile chub monitoring [JCM] reach in the Colorado River [63.4-65.0 river miles downstream of Lees Ferry], lower LCR [0-13.56 km upstream of Colorado River confluence], and upper LCR [13.57-17.9 km upstream of Colorado River confluence]).

Point shapefile of Wind Turbine locations in Wyoming as of December 2010. Turbine location and attribute data extracted from the FAA Obstruction Evaluation Database (https://oeaaa.faa.gov/oeaaa/external/portal.jsp). The FAA requires evaluation of any wind turbine (or structure) over 200ft. Therfore any wind turbine under 200ft would not be included in this data layer. In 2008 the FAA put a focus on wind turbines creating region categories specifically for wind turbines. With this, records for wind turbines before 2008 are less inclusive. The FAA database provides no determination of Wind Turbines that have been built and Wind Turbines that are still in planning stages. Therefore this layer includes Wind Turbines...

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth,...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
