 Hydrogeology (unknown)
This dataset portrays the hydrogeologic function of bedrock geology as compiled by Tim Bartos USGS. A primary goal of this work is to develop geologic map datasets with standardized structure and attribution. The database design and standards are documented in Chapter A of this series. The intent is that contiguous databases can be merged seamlessly and without any additional effort. In addition to a common database structure, the conterminous U.S. state databases (the contiguous 48 states) have been fitted to a set of standard state boundaries so that, when states are merged, they match without slivers or overlap. No attempt has been made to reconcile differences in mapping across state boundaries.

 Lakes (unknown)
The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.

 Estimated Net Annual Aquifer Recharge (1994-1998)
This dataset represents an estimated representation of net annual recharge of surficial aquifers in the Wyoming Snake/Salt River basin from natural sources. Irrigation or other man-made recharge structures are not represented. Estimated recharge is calculated using a simplistic formula based on soil type and average annual rainfall. The dataset is in raster format with 100 meter cell size. The recharge dataset was developed specifically to aid in the creation of a Wyoming ground-water vulnerability to surface contamination study conducted at the Wyoming Water Resources Center. The DRASTIC-based model requires surficial aquifer recharge as one of its parameters. For more details about this dataset, please refer to this report: Hamerlinck, J.D. and Arneson, C.S., editors, 1998, Wyoming Ground-Water Vulnerability Assessment Handbook: Volume 1.

 Aquifer Sensitivity (unknown)
This dataset represents Aquifer Sensitivity to surface contamination for Wyoming Snake/Salt River Basin at 1:100,000-scale. The purpose of this data layer is to provide citizens of Wyoming with an overview of the relative sensitivity of their surficial aquifers to contaminants applied on or near the land surface. It is intended as a regional planning and educational tool. For further information about this layer which was produced by the Wyoming Ground Water Vulnerability Mapping.
