title: Streambed sediment data for Missouri and Niobrara Rivers, Nebraska and South Dakota, 2015

description: Deltaic sand deposits at the head of Lewis and Clark Lake, Nebraska-South Dakota were investigated for suitability for use as a proppant feedstock resource in unconventional oil or gas production. The physical characteristics of the deposits are described in four supplemental data sets in varied file formats. First, for the direct-push cores collected at four sandbar complexes in the Missouri River delta, detailed descriptions of core lithology and texture are provided in Comma Separated Values (CSV) file format. Second, apparent resistivity results from capacitively coupled (CC) resistivity profiles collected along surface-geophysical reconnaissance lines are displayed using standardized color ramps and vertically exaggerated scales. The data are provided in PNG file format. Third, laboratory reports of sediment particle size and shape statistics are provided as PDF-formatted sheets, typically with three sheets per sample corresponding to optical particle-size analyzer (OPSA) results for (1) the washed sample, (2) the subsample sieved to retain only the dominant proppant size class (for example, API 40/70 size or 70/140 size), and (3) the same subsample after undergoing a crush-resistance test at a single stress level of 34.5 MPa (5,000 lbf/in2). These laboratory reports also include graphs showing the particle-size distributions measured by the OPSA. Fourth, photomicrographs of each sample, often but not always provided for each of the three OPSA-analyzed subsamples of each sample. For scale, each photomicrograph includes a 0.5-mm (500 micron)-diameter pencil lead within the field of view. The images are provided in JPEG file format. Images are located with the laboratory results for each sample.

title: Flood-inundation geospatial datasets for the Salamonie River at Portland, Indiana

description: Digital flood-inundation maps for a 6.5-mile reach of the Salamonie River at Portland, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science website at https://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage on the Salamonie River at Portland, Indiana (station 03324200). Near-real-time stages at this streamgage may be obtained from the USGS National Water Information System web interface at https://doi.org/10.5066/F7P55KJN or the National Weather Service Advanced Hydrologic Prediction Service (site PORI3) at https:/water.weather.gov/ahps/. Flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated using the current stage-discharge relation at the Salamonie River at Portland, Indiana, streamgage. The hydraulic model then was used to compute nine water-surface profiles for flood stages at 1-foot (ft) intervals referenced to the streamgage datum and ranging from 10.7 ft or near bankfull to 18.7 ft, which equals the highest point on the streamgage rating curve. The simulated water-surface profiles then were combined with a geographic information system digital elevation model (derived from light detection and ranging data having a 0.49-ft root mean square error and 4.9-ft horizontal resolution, resampled to a 10-ft grid) to delineate the area flooded at each stage. The availability of these maps, along with information regarding current stage from the USGS, will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures, and for postflood recovery efforts.

title: MODFLOW NWT groundwater flow model used to evaluate conditions in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming

description: A three-dimensional groundwater flow model was developed to characterize groundwater resources and the interaction of groundwater with streams and other hydrologic features in the Northern High Plains aquifer. The Northern High Plains aquifer is generally unconfined; most of the water withdrawn from the aquifer is used for irrigation. Recharge was estmated using a modified version of a previously published soil-water-balance (SWB) model and other data. SWB estimates recharge using climatic, soils, landcover data, in addition to data for groundwater withdrawals for irrigation. The SWB output was adjusted in areas where surface water is used for irrigation. The groundwater flow model results were calibrated using parameter estimation to measured groundwater levels and estimated stream base flows. The model was designed as a tool for regional evaluations of groundwater resources and of groundwater interactions with streams and other hydrologic features resulting from current or forecasted conditions. This USGS data release contains all of the input and output files for the model described in the associated model documentation report (http://dx.doi.org/10.3133/sir20165153). This data release also includes (1) MODFLOW NWT (version 1.0.9) source code, and (2) SWB source code in two formats.

title: Base of aquifer contours for the Northern High Plains aquifer

description: Several pre-existing datasets that characterize portions of the Northern High Plains aquifer base were merged together, and interpretively refined with test hole data, in order to define the entire base of the Northern High Plains aquifer. This digital dataset consists of the aquifer base altitude contours (100-foot contour interval) for the northern portion of the High Plains aquifer in the central United States. This was used as the lower boundary condition for a computer simulation model being used for a hydrologic study of the Northern High Plains

title: Water-level and aerial thermal infrared imagery data collected along the lower Platte and Elkhorn Rivers, Nebraska, 2016-2017

description: This dataset includes measured water-levels, water-level contours, aerial thermal infrared (TIR) imagery, and a stream centerline that were used to describe groundwater movement and interaction with surface water between the lower Platte and lower Elkhorn Rivers upstream of their confluence.  The study design described herein focused on understanding seasonal characteristics of groundwater movement and interaction with surface water during periods of high groundwater demand (June through August) and low groundwater demand (all other months).  Measured groundwater level and surface-water level data were collected during a low groundwater demand period in fall of 2016 and a high groundwater demand period in summer of 2017.  Two sets of water-level contours were manually digitized within a Geographic Information System (GIS) to describe groundwater movement and flow directions for the low groundwater demand period and the high groundwater demand period.  A georeferenced mosaic of high-resolution, aerial thermal infrared (TIR) images of the lower Elkhorn River, Nebraska, are presented as a gridded (raster) image in GeoTiff format.  The image is a 1.64-ft by 1.64-ft grid of corrected surface temperatures, in degrees Fahrenheit, of the lower Elkhorn River and adjacent area.  The dataset encompasses a 10-mile reach of the river, from 0.4 miles upstream from U.S. Geological Survey (USGS) streamflow-gaging station 06800500, Elkhorn River at Waterloo, Nebraska, to 1.8 miles downstream from USGS site 06800800, Elkhorn River at Q St Bridge near Venice, Nebraska.  A reach centerline was manually digitized in a GIS along the 100-mile reach.  Stream surface temperatures were extracted from the aerial TIR imagery and plotted against distance downstream to interpret groundwater discharge patterns.

title: Flood-inundation geospatial datasets for the North Platte River at Scottsbluff and Gering, Nebraska

description: Digital flood-inundation maps for an 8.8-mile reach of the North Platte River, from 1.5 miles upstream of the Highway 92 bridge to 3 miles downstream of the Highway 71 bridge, were created by the U.S. Geological Survey (USGS) in cooperation with the Cities of Scottsbluff and Gering. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science website at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage on the Platte River at Scottsbluff, Nebr. (station 06680500). Near-real-time stages at this streamgage may be obtained on the Internet from the USGS National Water Information System at https://doi.org/10.5066/F7P55KJN or from the National Weather Service Advanced Hydrologic Prediction Service (site SBRN1) at https://water.weather.gov/ahps2/. Flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated by using the current (2018) stage-discharge relation at the Platte River at Scottsbluff, Nebr., streamgage. The hydraulic model was then used to compute 10 water-surface profiles for flood stages at 1-foot (ft) intervals referenced to the streamgage datum and ranging from 9 ft, or near bankfull, to 18 ft, which exceeds the stage that corresponds to the estimated 1-percent annual exceedance probability flood (100-year recurrence interval flood). The simulated water-surface profiles were then combined with a Geographic Information System digital elevation model derived from light detection and ranging data having a 0.6-ft root mean square error and 2-ft horizontal resolution resampled to a 6-ft grid to delineate the area flooded at each water level. The availability of these maps, along with internet information regarding current stage from the USGS streamgage will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures, as well as for post flood recovery efforts.

title: Water-level and digital data for the Elkhorn and Loup River Basins groundwater flow model, Phase Three

description: The U.S. Geological Survey, in cooperation with the Lewis and Clark, Lower Elkhorn, Lower Loup, Lower Platte North, Lower Niobrara, Middle Niobrara, Upper Elkhorn, and the Upper Loup Natural Resources Districts, designed a study to refine the spatial and temporal discretization of a previously modeled area. This updated study focused on a 30,000-square-mile area of the High Plains aquifer and constructed regional groundwater-flow models to evaluate the effects of groundwater withdrawal on stream base flow in the Elkhorn and Loup River Basins, Nebraska. The model was calibrated to match groundwater-level and base-flow data from the stream-aquifer system from pre-1940 through 2010 (including predevelopment (pre-1895), early development (1895-1940), and historical development (1940 through 2010) conditions) using an automated parameter-estimation method. The calibrated model then was used to simulate hypothetical development conditions (2011 through 2060). Predicted changes to stream base flow based on simulated changes to groundwater withdrawal will aid in developing strategies for management of hydrologically connected water supplies.

title: Interpolated groundwater-level surface, spring 2017, Bazile Groundwater Management Area, northeastern Nebraska

description: This data set is a raster that represents the groundwater-level surface within the Bazile Groundwater Management Area (BGMA) in spring of 2017. This raster was created for use within the Geoscene3D program which combines airborne electromagnetic geophysical data along with supporting information for visualization and geological modeling. A water-level surface was created as input to a Geoscene3D project created covering the BGMA. The water-level surface was created using 58 water-levels measured from January to June of 2017 to represent water-level conditions prior to the onset of seasonal groundwater irrigation. The distribution of water-levels provided adequate coverage to the Bazile Groundwater Management area; however, high relief areas near Verdigre Creek and Bazile Creek are not adequately covered. In an effort to create a water-level surface map that is representative of the entire BGMA, water-level contours representing 1995 water levels first were compared to discreet spring 2017 water levels. The 1995 water-levels were published by the University of Nebraska Lincoln Conservation and Survey Division. These datasets were imported into ArcGIS as shapefiles. In general, water levels from both datasets were similar; however, two water levels from shallow wells located within the glaciated part of the BGMA were removed from the spring 2017 discrete water-level measurements. The water levels measured in each of these wells were much shallower when compared to the 1995 statewide water-level map contours, most likely because they are perched water levels representative of localized conditions, rather than the regional groundwater flow system.

title: Velocity and Bathymetric Data near Outlet Structures for the City of Omaha Water Resource Recovery Facilities on the Missouri River, 2020

description: These data sets were derived from surveys at the Missouri River and Papillion Creek Water Resource Recovery Facility outfalls on the Missouri River. Each site had three transects, one at the outfall, one 45.7 meters upstream of the outfall and one 45.7 meters downstream of the outfall. Velocity and depth data were collected using an acoustic Doppler current profiler at each transect. Elevations of water surface, bank topography, and shallow channel bed elevations were collected at each transect using survey grade Global Navigation and Satellite System instruments connected to the High Precision Real-Time Kinematic (HPRTK) correction service (https://hprtk.net). Data were processed using Velocity Mapping Toolbox: a processing and visualization suite for moving-vessel acoustic Doppler current profiler measurements, Parsons and others, 2013.  Data from the surveyed cross-section at the outfall of each site were also processed to estimate discharge during the time of the survey. The discharge during data collection at the Papillion Creek Water Resource Recovery Facility outfall was 1,005 cubic meters per second (35,500 cubic feet per second) at around 4:00 pm central standard time and at the Missouri River Water Resource Recovery Facility outfall was 1,020 cubic meters per second (36,000 cubic feet per second) at around 6:00 pm central standard time.  This data release contains two comma separated value files. The file named Missouri_River_Papillion_Creek_WRRF_BedElevations&Topopoints_UTM15M.csv contains Universal Transverse Mercator zone 15 Northing, Easting, and elevation information for all survey points including bathymetry and Global Navigation and Satellite System data and the Water Resource Recovery Facility where the data were collected. The file named Missouri_River_Papillion_Creek_WRRF_Velocity_UTM15M.csv contains velocity specific positioning data and depth averaged velocity data.

title: Niobrara River Bathymetric and Topographic Surveys to Assess Topobathymetric Lidar Accuracy, 2020

description: The Niobrara River is a National Scenic River in northern Nebraska.  The Niobrara River is characterized by a sand channel with areas of gravel and bedrock.  Bathymetric and topographic surveys were completed at five sites (Norden, Meadville, Mariaville, Spencer, and Niobrara) on the Niobrara River in August 2020. The bathymetric data were collected using Acoustic Doppler Current Profilers (ADCPs) attached to kayaks.  The ADCP data were collected on transects and between the transects following the flow of the river at each site.  Topographic data including water surface elevations were collected with survey grade Global Navigation Satellite Systems (GNSS).  A temporary reference point was established at each of the five sites on which a GNSS base station was deployed.  Eight to fourteen hours of static satellite observation data were collected over the temporary mark and submitted to the National Geodetic Survey Online Positioning Users Serve (OPUS) to get an accurate horizontal and vertical position on the temporary mark.  This corrected position for the base station was used to adjust and correct the rover data (water surface elevations and shallow streambed elevations).  Water surface elevations were applied to the data collected along each transect to give a cross-section of streambed elevation from the measured depth.  For data collected in between transect lines, a slope model was used to apply water surface elevations to the measured depths to give a longitudinal profile of streambed elevation.  At random locations with depth greater than 0.15 meters (m), light intensity measured by a LICOR LI-192 Underwater Quantum Sensor in Micro mol of photons m^-2 s^-1, Secchi depth m, and turbidity Formazin Nephelometric Unites (FNU)) were measured.  The data will be used by the Earth Resources Observation and Science Center (EROS) to evaluate topobathymetric lidar data collected with a Riegl VQ-880-G topobathymetric lidar sensor.  The Niobrara River provided environmental conditions with varying degrees of streambed type, water clarity, and depth that were useful in understanding lidar sensor performance.  Bathymetric and GNSS survey data were collected during the same day as the topobathymetric lidar data to ensure an accurate comparison because each site had a complete or partial sand streambed.  The light intensity, Secchi depth, and turbidity readings will be used to determine water clarity.  The water clarity will be used to evaluate the effectiveness of the topobathymetric lidar sensor and assess the conditions that are optimal for the topobathymetric lidar sensor use.  Two data files in comma separated values format are included: Niobrara_River_Bathymetry_GNSS_Data_2020.csv which includes streambed elevations from the ADCP and GNSS surveys and Niobrara_River_Light_Secchi_Turb_Readings_2020.csv which includes water clarity data.

title: Bathymetric and Topographic Survey of the Platte River and associated chutes near the Nebraska Army National Guard Camp Ashland Training Site, 2019-2020

description: These data are the survey results from a five-mile section of the Platte River at, and upstream of the Nebraska Army National Guard Camp Ashland Training Site including the side channel chutes on the east bank. All survey data were collected along planned transect lines that were spaced 492.125 US survey feet apart beginning near the mouth of the Elkhorn River and ending near the U.S. Highway 6 bridge. An effort was made to get complete elevation data for each transect from top of bank to top of bank. Survey grade Global Navigation and Satellite Systems (GNSS) receiving antennas connected to a real time network (RTK high precision network https://hprtk.net) were used to measure elevation along the transects, at the top of banks, along the slope of the banks, at control structures, on islands and sandbars and on the streambed in areas of the wetted channel that were wadable. GNSS data collection methods followed level 3, RTN procedures as described by (Rydlund and Densmore, 2012). An acoustic Doppler current profiler (ADCP) was used to measure streambed elevation in areas of the wetted channel that were not wadable. ADCP data were processed using Velocity Mapping Toolbox (Parsons and others, 2013) to convert measured depths to elevation. This data release contains two comma separated value files. The CSV file named PlatteRiver_GNSS_SurveyData_20200924-20210402.csv contains the GNSS survey data. The CSV file named Bathy_ADCP_final_data_SPCS.csv contains bathymetric survey data.
