The U.S. Geological Survey (USGS), prepared geographic information systems (GIS) layers for use in the West Virginia StreamStats application. The Digital Elevation Model and associated data were hydrologically conditioned, which is the process of burning in single line streams at the 1:24,000 scale into a digital elevation model to produce flow direction and flow accumulation grids. This data includes geotif images for a 10 meter digital elevation model, a flow direction, and a flow accumulation raster/grid image for the WV Streamstats area. The 34 HUCs represented by this dataset are 02070001, 02070002, 02070003, 02070004, 02070005, 02070006, 02070007, 05020001, 05020002,05020003, 05020004, 05020005, 05020006, 05030101, 05030106, 05030201, 05030202, 05030203, 05050001, 05050002, 05050003, 05050004,05050005, 05050006, 05050007, 05050008, 05050009, 05070101, 05070102, 05070201, 05070202, 05070204, 05090101, and 05090102.

The U.S. Geological Survey (USGS), in cooperation with the Federal Emergency Management Agency, Pennsylvania Department of Environmental Protection, Pennsylvania Department of Transportation, and Susquehanna River Basin Commission, prepared hydro-conditioned geographic information systems (GIS) layers for use in the Pennsylvania StreamStats application.

In cooperation with the Federal Emergency Management Agency, the Pennsylvania Department of Transportation, the Pennsylvania Department of Environmental Protection, and the Susquehanna River Basin Commission, the U.S. Geological Survey (USGS) calculated over 20 different basin characteristics as part of preparing the Pennsylvania StreamStats 2020 application. These datasets are raster representations of various environmental, geological, and land use attributes within the Pennsylvania StreamStats 2020 study area, and will be served in the Pennsylvania 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.
