This dataset contains elevation and pebble count data for 5 new sites located at streamflow-gaging stations in the glaciated setting of Pennsylvania and southern New York. Sites were surveyed in 2016 and the elevation data represent topographic features (bankfull, thalweg, etc.) along longitudinal and cross sectional areas of stream reaches. The pebble counts were collected within each cross section. Drainage areas from StreamStats for 70 streamflow-gaging stations in Pennsylvania are also provided.

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. These data were used to update the peak flow and low flow regression equations for Pennsylvania. This dataset consists of digital elevation model rasters for each 8-digit Hydrologic Unit Code (HUC) area in Pennsylvania, one of the layer types needed to delineate watersheds within the HUC-8 areas, merged into a single dataset. The 59 HUCs represented by this dataset are 02040101, 02040102, 02040103, 02040104, 02040105, 02040106, 02040201, 02040202, 02040203, 02040205, 02050101, 02050102, 02050103, 02050104, 02050105, 02050106, 02050107, 02050201, 02050202, 02050203, 02050204, 02050205, 02050206, 02050301, 02050302, 02050303, 02050304, 02050305, 02050306, 02060002, 02060003, 02070002, 02070003, 02070004, 02070009, 04110003, 04120101, 04130002, 05010001, 05010002, 05010003, 05010004, 05010005, 05010006, 05010007, 05010008, 05010009, 05020001, 05020002, 05020003, 05020004, 05020005, 05020006, 05030101, 05030102, 05030103, 05030104, 05030105, and 05030106.

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.

This USGS Data Release includes hydrologic data compiled for selected years during the period 1990-2017 to support the development and calibration of a numerical groundwater model used to simulate groundwater flow paths at and near former and currently active military bases in Montgomery and Bucks Counties in southeastern Pennsylvania (Goode and Senior, 2020). The hydrologic data compiled for the study area include: 1) withdrawal (pumping) rates for production and other wells; 2) quarry pumping rates; 3) rates of flow discharged to streams from the National Pollution Discharge Elimination System (NPDES) sources, and 4) measured water levels in wells. The data were compiled from various sources described in the metadata for each type of data, with complete references for data sources listed in (Goode and Senior, 2020). Withdrawal (pumping) and discharge rates in the data release represent annual average rates computed as needed from data compiled from various sources. The principal time periods for compiled data include 1990's, 2010, 2013, 2016, and 2017. Some values are estimated where data were missing or not available.

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the Bedrock geology of the Evitts Creek and Patterson Creek quadrangles, Maryland, Pennsylvania, and West Virginia from the original map of de Witt and Colton, 1964. Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in the U.S. Geological Survey Bulletin 1173 with no adjustments made to any of the map data. The Description of Map Units (DMU) summarizes descriptions of the same lithostratigraphic units from adjacent maps published by the same author in the area and is expanded from the text published in the the original report. Some revisions to stratigraphic nomenclature were made to conform with modern usage. When symbolized according to the accompanying Federal Geographic Data Committee (FGDC) style file, this data release presents the geologic map as shown on the published map by de Witt. MapUnitPolys labels may be symbolized according to the accompanying FGDC Opentype Font file (FGDCGeoAge) for special geologic age characters. Surficial map data is not represented in this geodatabase. Surficial map data is not represented in this geodatabase.
