The U.S. Geological Survey (USGS), in cooperation with the New Jersey Department of Environmental Protection (NJDEP), calculated several basin characteristics as part of the updated New Jersey StreamStats 2022 application (U.S. Geological Survey, 2022). These datasets are raster representations of various environmental, geological, and land use attributes within the New Jersey StreamStats 2022 study area; they are applied in the New Jersey 2022 application to describe delineated watersheds. This update features improvements in base elevation resolution from 10 meters to 10 feet and stream centerline hydrography from 1:24,000 to 1:2,400, as well as resampling of previously existing datasets to match the 10-foot resolution. The sixteen 8-digit Watershed Boundary Dataset Hydrologic Unit Codes (HUCs) represented by these datasets are 02020007, 02030103, 02030104, 02030105, 02040101, 02040102, 02040103, 02040104, 02040105, 02040106, 02040201, 02040202, 02040203, 02040206, 02040301, and 02040302 (U.S. Geological Survey, 2016). The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, as well as engineering and design purposes. The map-based user interface can be used to delineate drainage areas, determine basin characteristics and estimate flow statistics, including instantaneous flood discharge, monthly flow-duration, and monthly low-flow frequency statistics for ungaged streams.

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) has calculated over 25 different basin characteristics as part of preparing the West Virginia StreamStats 2021 application. These datasets are raster representations of various environmental, geological, and land use attributes within the West Virginia StreamStats 2021 study area. This study area was defined by Watershed Boundary HUC 8 digital data, and as such there is an area of about 70 square miles in the SE corner of WV is not included in these raster datasets as it drains towards Virginia. The basin characteristics data will be served in the West Virginia StreamStats 2021 application used 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 for data-collection stations and user-selected ungaged sites.
