Correlation of flows at pairs of streamgages were evaluated using a Spearman’s rho correlation coefficient to better identify gages that can be used as index gages to estimate daily flow at ungaged stream sites in West Virginia. Correlation maps were developed for each candidate index streamgage using ordinary kriging, and have been compiled as grids. Sets of grids were developed for correlation of daily flows of streamgages on unregulated streams in and near (within 50 miles of) West Virginia that were operated during the 1930-2011 water years for: (1) complete water years for the entire period of record (1930-2011), (2) October-December for the entire period of record, (3) January-March for the entire period of record, (4) April-June for the entire period of record, (5) July-September for the entire period of record, (6) complete water years for 1963-1969, (7) complete water years for 1970-1979, and (8) complete water years for 1992-2011.

From the site: "A reference map of the total intensity magnetic field of the earth in gammas published by the WV Geological and Economic Survey in 1978.

In May/June 2007, two hardcopy map sheets of the 1978 Aeromagnetic Map of West Virginia were scanned at 300 dpi 8-bit color by the WV GIS Technical Center. The scanned TIFs were converted to index color mode, and resampled to 150 dpi. The map sections were then mosaicked together and georeferenced to a 15-minute Longitude/Latitude grid."

The mapped area boundary, flood inundation extents, and depth rasters were created to provide an estimated extent of flood inundation along the Cherry River within the communities of Richwood and Fenwick, West Virginia. These geospatial data include the following items: 1. cherry_bnd; shapefile containing the polygon showing the mapped area boundary for the Cherry River flood maps, 2. cherry_hwm; shapefile containing high-water mark points, 3. polygon_cherry_hwm; shapefile containing mapped extent of flood inundation, derived from the water-surface elevation surveyed at high-water marks, 4. depth_hwm; raster file for the flood depths derived from the water-surface elevation surveyed at high-water marks, 5. polygon_cherry_dem; shapefile containing mapped extent of flood inundation, derived from the height above ground recorded at high-water marks and the digital elevation model (DEM) raster, 6. depth_dem; raster file for the flood depths derived from the height above ground recorded at high-water marks and the digital elevation model raster. The upstream and downstream mapped area extent is limited to the upstream-most and downstream-most high-water mark locations. In areas of uncertainty of flood extent, the mapped area boundary is lined up with the flood inundation polygon extent. The mapped area boundary polygon was used to extract the final flood inundation polygon and depth raster from the water-surface elevation raster file. Depth raster files were created using the "Topo to Raster" tool in ArcMap (ESRI, 2012). For this study two sets of inundation layers were generated for each reach. One raster file showing flood depths, "depth_hwm", was created by using high-water mark water-surface elevation values on the land surface and a digital elevation model. However, differences in elevation between the surveyed water-surface elevation values at HWM’s and the land-surface elevation from the digital elevation model data provided uncertainty in the inundation extent of the generated layers. Often times elevation differences of +/- 20 feet were noticed between the surveyed elevation from a HWM on the land surface and the digital elevation model land-surface elevation. Due to these elevation differences, we incorporated a second method of interpolating the water-surface layer. The recorded height above ground value from the surveyed HWM was added to the digital elevation model land-surface elevation at that point. This created a new water-surface elevation value to be used with the “Topo to Raster” interpolation method to create a second depth raster, "depth_dem". Both sets of inundation layers are provided.

From the site: “A Digital Raster Graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) topographic map. An unclipped scanned image includes all marginal information, while a clipped or seamless scanned image clips off the collar information. DRGs may be used as a source or background layer in a geographic information system, as a means to perform quality assurance on other digital products, and as a source for the collection and revision of digital line graph data. The DRGs also can be merged with other digital data (e.g., digital elevation model or digital orthophotoquad data), to produce a hybrid digital file.

The output resolution of a DRG varies from 250 to 500 dots per inch. The horizontal positional accuracy of the DRG matches the accuracy of the published source map. To be consistent with other USGS digital data, the image is cast on the UTM projection, and therefore, will not always be consistent with the credit note on the image collar. Only the area inside the map neatline is georeferenced, so minor distortion of the text may occur in the map collar. Refer to the scanned map collar or online Map List for the currentness of the DRG.”

The database for the geologic map of the Frederick 30 x 60 quadrangle covers the distinct geologic provinces and sections of the central Appalachian region that are defined by unique bedrock and resulting landforms. From west to east, the provinces include the Great Valley section of the Valley and Ridge province, the Blue Ridge province, and the Piedmont province; in the extreme southeastern corner, a small part of the Coastal Plain province is present. The Piedmont province is divided into several sections; from west to east, they are the Frederick Valley synclinorium, the Culpeper and Gettysburg basins, the Sugarloaf Mountain anticlinorium, the Westminster terrane, and the Potomac terrane. The Blue Ridge province contains Mesoproterozoic (1 billion years old, or 1 Ga) paragneiss and granitic gneisses that are intruded by a swarm of Neoproterozoic (570 million years old, or 570 Ma) metadiabase and metarhyolite dikes. Unconformably overlying the gneisses are Neoproterozoic metasedimentary rocks and metavolcanic rocks associated with the dikes. The Mesoproterozoic gneisses were deformed and metamorphosed during the Grenville orogeny. Subsequently, the Neoproterozoic metasedimentary and metavolcanic rocks accumulated during a continental rifting event (Rankin, 1976). Clastic metasedimentary rocks of the newly formed continental margin were deposited paraconformably upon the Neoproterozoic rocks. To the east, Neoproterozoic and early Paleozoic metasedimentary and metavolcanic rocks were deposited on the margin of the rifted continent. These rocks underlie the Sugarloaf Mountain anticlinorium and Westminster and Potomac terranes. As the rifted continental margin stabilized and became a passive margin during the early Paleozoic, carbonate rocks were deposited on the broad continental shelf. Those carbonate rocks are now exposed in the Great Valley section and the Frederick Valley synclinorium. The early Paleozoic carbonate platform became unstable in response to the Ordovician Taconian orogeny. Deformation associated with this tectonic event is recorded in rocks of the Piedmont province to the east. These rocks, which are now part of the Potomac terrane, were thrust westward onto rocks of the Westminster terrane; next, rocks of the Westminster terrane were thrust onto rocks now exposed in the Sugarloaf Mountain anticlinorium and Frederick Valley synclinorium (Drake and others, 1989; Southworth, 1996). The early Paleozoic sea eventually closed up and disappeared during the continental collision of tectonic plates during the late Paleozoic Alleghanian orogeny. The Alleghanian orogeny transported all of the rocks within the map area westward along the North Mountain thrust fault, which is exposed immediately northwest of the quadrangle. The Alleghanian orogeny produced numerous thrust faults and folds in the rock and regional-scale folds that help define the geologic provinces. The Massanutten synclinorium underlies the Great Valley section, the Blue Ridge-South Mountain anticlinorium underlies the Blue Ridge province, and the Frederick Valley synclinorium and Sugarloaf Mountain anticlinorium underlie the western Piedmont province. Tens of millions of years after the Alleghanian orogeny, early Mesozoic continental rifting formed the Culpeper and Gettysburg basins, which once were connected to form a large down-faulted basin filled with sediments that eroded from the adjacent Blue Ridge and Piedmont highlands. Continued rifting resulted in igneous intrusions and extrusive volcanic rock at about 200 Ma, and eventually led to the opening of the Atlantic Ocean to the east. Sediments eroded from the Appalachian highlands were deposited by river systems and transgressing seas and now form the Coastal Plain province.

This map shows high-resolution (1 meter) land cover in the EPA Region 3, covering the parts of West Virginia, Virginia, and Pennsylvania outside of the Chesapeake Bay Watershed. It contains the following classes: Water, Tree Canopy, Scrub\Shrub, Low Vegetation, Barren, Impervious Structures, Other Impervious, Impervious Roads, Tree Canopy Over Impervious Structures, Tree Canopy Over Other Impervious, and Tree Canopy Over Impervious Roads. Using object-based image analysis mapping techniques, it was mapped from a combination of remote-sensing imagery and GIS datasets, including LiDAR, multispectral imagery, and thematic layers (e.g., roads, building footprints). Draft output was then manually reviewed and edited to eliminate obvious errors of omission and commission. The classification scheme closely follows a similar mapping effort for the Chesapeake Bay Watershed; together, maps from the two projects cover the entirety of the EPA Region 3 states. One difference between the projects, however, is that tidal wetlands were mapped in the Chesapeake Bay effort, included as the class Emergent Wetlands, but not in the EPA Region 3 zones outside of the watershed. The map is considered current as of 2020 for West Virginia, 2021 for Virginia, and 2022 for Pennsylvania.
