This ArcView shapefile contains a polygon representation of the Deadman coal zone in the Black Butte area of the Point of Rocks-Black Butte coalfield, Wyoming. This boundary is a part of the National Coal Resource Assessment of the Northern Rocky Mountain and Great Plains Fort Union Coal Resources Assessment Area. This coal zone can be shown in relation to other relevant themes of this area.

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. As part of the U.S. Geological Survey's National Water-Quality Assessment Program, an investigation of the Yellowstone River Basin study unit is being conducted to document status and trends in surface- and ground-water quality. Efficient quantification of a variety of environmental and geographic characteristics of the study unit requires a digital map of the study-unit boundary that may be processed, together with other digital...

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;...
The mapped area boundary, flood inundation extents, and depth rasters were created to provide an estimated extent of flood inundation along the Elk River within communities in Kanawha and Clay Counties, West Virginia. These geospatial data include the following items: 1. elk_bnd; shapefile containing the polygon showing the mapped area boundary for the Elk River flood maps, 2. elk_hwm; shapefile containing high-water mark points, 3. polygon_elk_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_elk_dem; shapefile...
The Nacatoch Sand in northeastern and southwestern Arkansas and the Tokio Formation in southwestern Arkansas are sources of groundwater for agricultural, domestic, industrial, and public use. Water-level altitudes measured in 51 wells completed in the Nacatoch Sand and 42 wells completed in the Tokio Formation during 2014 and 2015 were used to compile potentiometric-surface maps of the two areas. Aquifers in the Nacatoch Sand and Tokio Formation are hereafter referred to as the Nacatoch aquifer and the Tokio aquifer, respectively. Potentiometric surfaces show that groundwater in the Nacatoch aquifer flows southeast toward the Mississippi River in northeastern Arkansas. Groundwater flow direction is towards the south...
The Nacatoch Sand in northeastern and Arkansas, is sources of groundwater for agricultural, domestic, industrial, and public use Clay and Green Counties. Water-level altitudes measured in 12 wells completed in the Nacatoch Sand and were used to create a potentiometric-surface map. Potentiometric surfaces show that groundwater in the Nacatoch aquifer flows southeast toward the Mississippi River in northeastern Arkansas. This shapefile contains the generalized study area of the Northeast Nacatoch aquifer.
