The National Water Quality Network (NWQN) for Rivers and Streams includes 113 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program (NWQP). The NWQN represents the consolidation of four historical national networks: the USGS National Water-Quality Assessment (NAWQA) Project, the USGS National Stream Quality Accounting Network (NASQAN), the National Monitoring Network (NMN), and the Hydrologic Benchmark Network (HBN). The NWQN includes 22 large river coastal sites, 41 large river inland sites, 30 wadeable stream reference sites, 10 wadeable stream urban sites, and 10 wadeable stream agricultural sites. In addition to the 113 NWQN sites, 3 large inland river monitoring sites from the USGS Cooperative Matching Funds (Co-op) program are also included in this annual water-quality reporting Web site to be consistent with previous USGS studies of nutrient transport in the Mississippi-Atchafalaya River Basin. This data release contains geo-referenced digital data and associated attributes of watershed boundaries for 113 NWQN and 3 Co-op sites. Two sites, "Wax Lake Outlet at Calumet, LA"; 07381590, and "Lower Atchafalaya River at Morgan City, LA"; 07381600, are outflow distributaries into the Gulf of Mexico. Watershed boundaries were delineated for the portion of the watersheds between "Red River near Alexandria, LA"; 07355500 and "Atchafalaya River at Melville, LA"; 07381495 to the two distributary sites respectively. Drainage area was undetermined for these two distributary sites because the main stream channel outflows into many smaller channels so that streamflow is no longer relative to the watershed area. NWQN watershed boundaries were derived from the Watershed Boundary Dataset-12-digit hydrologic units (WBD-12). The development of the WBD-12 was a coordinated effort between the United States Department of Agriculture-Natural Resources Conservation Service (USDA-NRCS), the USGS, and the Environmental Protection Agency (EPA) (U.S. Department of Agriculture-Natural Resources Conservation Service, 2012). A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Its boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream or similar surface waters. The United States is divided and sub-divided into successively smaller hydrologic units identified by a unique hydrologic unit code (HUC) consisting of two to 12 digits based on the six levels of classification in the hydrologic unit system: regions, sub-regions, accounting units, cataloging units, watersheds, and sub-watersheds. NWQN watershed boundaries were delineated by selecting all sub-watershed polygons that flow into the most downstream WBD-12 polygon in which the NWQN site is located. The WBD-12 attribute table contains 8-digit, 10-digit, and 12-digit HUCs which were used to identify which sub-watersheds flow into the watershed pour point at the NWQN site location. When the NWQN site was located above the pour point of the most downstream sub-watershed, the sub-watershed was edited to make the NWQN site the pour point of that sub-watershed. To aid editing, USGS 1:24,000 digital topographic maps were used to determine the hydrologic divide from the sub-watershed boundary to the NWQN pour point. The number of sub-watersheds which are contained within the NWQN watersheds ranged from less than one to nearly 32,000 internal sub-watersheds. Internal sub-watershed boundaries were dissolved so that a single watershed boundary was generated for each NWQN watershed. Data from this release are presented at the USGS Tracking Water Quality page: http://cida.usgs.gov/quality/rivers/home (Deacon and others, 2015). Watershed boundaries delineated for this release do not take into account non-contributing area, diversions out of the watershed, or return flows into the watershed. Delineations are based solely on contributing WBD-12 polygons with modifications done only to the watershed boundary at the NWQN site location pour point. For this reason calculated drainage areas for these delineated watersheds may not match National Water Information System (MWIS) published drainage areas (http://dx.doi.org/10.5066/F7P55KJN).

The hydrogen index (HI) is a parameter obtained from Rock-Eval data which reflects general hydrocarbon generation and maturation trends in petroleum systems. In the Mississippian Barnett Shale, the hydrogen index was used to map general boundaries between regions of oil and gas generation within the extents of the formation. Hydrogen index values were obtained via Rock-Eval analyses of Barnett Shale core samples. In this system, HI values greater than 100 represent primarily oil generation and HI values less than 100 represent primarily gas generation. Secondary gas generation is indicated by HI values less than 50. In addition, the 100 HI line was utilized to establish part of the assessment unit (AU) boundaries for the 2015 assessment of shale gas and shale oil resources of the Barnett Shale in the Bend Arch-Fort Worth Basin Province. The AU represents the fundamental boundary used in the National and Global Assessment Project for the assessment of undiscovered oil and gas resou ...

This dataset provides detailed soil mapping and associated attributes for Bedford County, Virginia, developed through the USDA's Soil Survey Geographic (SSURGO) database program. It includes georeferenced vector data and tabular attributes sourced from the National Soil Information System (NASIS). The mapping was conducted at a scale of 1:24,000 and offers information on soil composition, properties, and suitability for land use, engineering, agriculture, conservation, and recreation.

This data is shared publically on the open data hub for Bedford County, VA. Bedford County GIS is responsible for maintaining the data in the layer and to review it every 3 years. It is expected to be maintained indefinitely.

The SSURGO dataset includes:

• Polygon features representing soil map units.
• Optional special soil features (point/line) for features too small to be mapped as polygons.
• Linkages to NASIS attribute data, including physical and chemical soil properties, as well as interpretations for common land uses.
