These raster data represent spatially distributed slope percentages in the Nevada StreamStats study area for the period of 2024.

This data release contains raster geospatial data for characterizing drainage basins in the Nevada StreamStats study area. Included are precipitation, temperature, elevation, slope, and land cover data.

This data release contains vector and raster geospatial data for delineating drainage basins in the Nevada StreamStats study area. Included are vector streamline, waterbody, and inner wall data used to hydrologically condition the digital elevation model. The hydrologically-conditioned digital elevation model, flow direction, flow accumulation, and stream delineation raster data are also included.

These vector data represent the 8-digit hydrologic unit (HU8) polygons used to define the raster processing extent in the Nevada StreamStats study area.

This dataset was produced in by the Delaware Geological survey in cooperation with the US Geological Survey and Delaware Department of Transportation for the purpose of calculating stream gage basin characteristics in preparation for the Delaware 2020 StreamStats application. These datasets are raster representations of various environmental, geological, and land use attributes within the Delaware StreamStats 2020 study area, and will be served in the Delaware StreamStats 2020 application to describe delineated watersheds. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more.

This dataset was produced in by the Delaware Geological survey in cooperation with the US Geological Survey and Delaware Department of Transportation for the purpose of delineating gage basins and performing hydrologic analysis in the Delaware 2020 StreamStats application. These datasets are raster representations of the fundamental dataset layers necessary for the functionality of StreamStats application within the Delaware StreamStats 2020 study area. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. The datasets include a study area defined by all HUC12 watersheds flowing into or out of the state of Delaware, which includes portions of HUC08 watersheds 02040202, 02040205, 02040207, 02040303, 02060002, 02060005, 02080109, 02080110, and 02080111.

The U.S. Geological Survey (USGS), in cooperation with the Louisiana Department of Transportation, prepared hydro-conditioned geographic information systems (GIS) layers for use in the Louisiana StreamStats application. These data were used within peak flow and low flow regression equations for Louisiana. This dataset consists of digital elevation model rasters for each 8-digit Hydrologic Unit Code (HUC) area in Louisiana, one of the layer types needed to delineate watersheds within the HUC-8 areas, merged into a single dataset. The 54 HUCs represented by this dataset are 03180004, 03180005, 08030100, 08040202, 08040205, 08040206, 08040207, 08040301, 08040302, 08040303, 08040304, 08040305, 08040306, 08050001, 08050002, 08050003, 08060100, 08070100, 08070201, 08070202, 08070203, 08070204, 08070205, 08070300, 08080101, 08080102, 08080103, 08080201, 08080202, 08080203, 08080204, 08080205, 08080206, 08090100, 08090201, 08090202, 08090203, 08090301, 08090302, 11140201, 11140202, 11140203, 11140204, 11140205, 11140206, 11140207, 11140208, 11140209, 11140304, 11140306, 12010002, 12010004, 12010005, and 12040201.

This dataset was produced by the U.S. Geological Survey (USGS) in cooperation with the Wyoming Water Development Office for the purpose of delineating drainage basins and performing hydrologic analysis in the Wyoming StreamStats application. The data are raster representations of the fundamental dataset layers necessary for the functionality of StreamStats application within the Wyoming StreamStats study area. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, calculate basin characteristics, and estimates of flow statistics, and more. The study boundary for data in this data release is defined by the extent of all HUC08 watersheds flowing in or out of the state of Wyoming.

This data set contains the potentiometric water-level altitude contours representing the 2009 potentiometric surface of the basin fill groundwater system of Dixie Valley, west-central Nevada.
