Interpolated groundwater-levels, western Sarpy County, eastern Nebraska This dataset is a file of contour lines representing the estimated altitude of the water table in western Sarpy County. This dataset was developed as part of a cooperative study between the Papillion-Missouri River Natural Resources District (PMRNRD) and USGS which began in 2017. The goal of this study was to develop a hydrogeologic visualization model of western Sarpy County using GeoScene3D. In 2016, the PMRNRD contracted airborne electromagnetic surveys (AEM) of the area to be completed to better understand the stratigraphy and hydrogeology of the western Sarpy County area. The PMRNRD determined that they wanted to incorporate the AEM data into a visualization tool that would allow PMRNRD staff to easily interact...

Niobrara River suspended-sediment and bed-sediment data collected during hydroelectric dam flush near Spencer, Nebr., October through November, 2014 In the fall of 2014 (October-November) the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers collected sediment samples (suspended and bed material) at several sites on the Niobrara River in Nebraska near the Spencer Dam prior to, during, and immediately after a sediment-flushing event. Suspended-sediment samples were analyzed for sediment concentration and percent finer than sand. Bed sediment samples were analyzed for particle-size distribution using standard classes by sieve analysis. In addition, a Sequoia LISST Streamside particle-size analyzer (PSA) was deployed during the first week of the flush; this unit collected suspended-sediment concentration and grain-size data. Sampled sites...

Estimated altitude of the top of the Pennsylvanian-age units in western Sarpy County, Nebraska This dataset includes a grid raster and contour line file representing the estimated altitude of the top of the Pennsylvanian-age units in western Sarpy County, Nebraska. This dataset was developed as part of a cooperative study between the PMRNRD and USGS which began in 2017. The goal of this study was to develop a hydrogeologic visualization model of western Sarpy County using GeoScene3D.

Datasets of altitude of the top of the Dakota Sandstone, top of the Pennsylvanian-age units, and water-level in western Sarpy County, Nebraska This Data Release is comprised of datasets used for the development of a hydrogeologic visualization model for western Sarpy County. Additional documentation on model development can be found in the associated Scientific Investigations Report. In 2016, the Papillion-Missouri River Natural Resources District (PMRNRD) contracted airborne electromagnetic surveys (AEM) of the area to be completed to better understand the stratigraphy and hydrogeology of the western Sarpy County area. The PMRNRD determined that they wanted to incorporate the AEM data into a visualization tool that would allow PMRNRD staff to easily interact with the AEM data and integrate it with other hydrogeologic and groundwater-quality data.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
