title: Spatial data set of mapped water-level changes in the High Plains aquifer, predevelopment (about 1950) to 2017 and 2015 to 2017

description: The High Plains aquifer underlies 111.8 million acres (about 175,000 square miles) in parts of eight States&mdash;Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Water-level declines began in parts of the High Plains aquifer soon after the beginning of substantial irrigation with groundwater in the aquifer area  (about 1950). This data release contains the data used to map water-level changes and change in recoverable water in storage in the High Plains aquifer from predevelopment (about 1950) to 2017 and from 2015 to 2017. This study was funded by the USGS Groundwater and Streamflow Information Program.

title: Datasets of depth to water, spring 2016, 2018, and 2020, and spring-to-spring water-level change 2016-18, 2018-20, and 2016-20, Mississippi River Valley alluvial aquifer

description: This data release consists of 4 data sets--rasters of generalized depth to water in the Mississippi River Valley alluvial aquifer (MRVA) in spring 2016, 2018, and 2020 and a point file of the wells with water-level measurements used to create the depth to water rasters and, for each well with applicable data, the values of water-level change from spring 2016 to spring 2018, spring 2018 to spring 2020, and spring 2016 to spring 2020. The MRVA underlies parts of seven states, including Arkansas, Illinois, Kentucky, Louisiana, Missouri, Mississippi, and Tennessee These data sets were created to characterize the depth to water in the MRVA and the value of water-level change at each well with the applicable data. These data sets can be used to facilitate understanding of the MRVA and to assist in further analysis of other MRVA data, as for example, water quality results.

title: Datasets used to map the base-flow recession time constants in the Niobrara National Scenic River in Nebraska, 2016-18

description: The base flow recession time constant (tau) is a hydrologic index that characterizes the ability of a ground-water system to supply flow to a stream draining from that system. Tau and other correlated hydrologic indices have been used as explanatory variables to greatly improve the predictive power of low-flow regression equations. Tau can also be used as an indicator of streamflow dependence on groundwater inflow to the channel. Tau values were calculated for 10 streamgages in the Niobrara National Scenic River study area. The calculated tau values were then used to create a kriged map. Kriging is a geostatistical method that can be used to determine optimal weights for measurements at sampled locations (streamgages) for the estimation of values at unsampled locations (ungaged sites). The kriged tau map could be used (1) as the basis for identifying areas with different hydrologic responsiveness, with differing potential to demonstrate the effects of management changes and (2) in the development of regional low-flow regression equations. The Geostatistical Analyst tools in ArcGIS Pro version 2.5.2 (Environmental Systems Research Institute, 2012) were used to create the kriged tau map and perform cross validation to determine the root mean square error (RMSE) of the tau map.

title: MODFLOW-One-Water model used to support the Central Platte Natural Resources District Groundwater Management Plan

description: An integrated hydrologic-flow model, called the Central Platte Integrated Hydrologic Model, was constructed using the MODFLOW-One-Water Hydrologic Model code with the Newton solver. This code integrates climate, landscape, surface water, and groundwater-flow processes in a fully coupled approach. This study provided the Central Platte Natural Resources District (CPNRD) with an advanced numerical modeling tool to assist with the update of their Groundwater Management Plan by providing them information on modeled future GW levels under different climate scenarios and management practices. This tool will allow the CPNRD to evaluate other scenarios as management changes in the future. A predevelopment model simulated steady-state hydrologic conditions prior to April 30, 1895 and a development period model discretized into 610 stress periods simulated transient hydrologic conditions from May 1, 1895, to December 31, 2016, using 170 biannual stress periods from 1895 to 1980, and monthly stress periods from May 1, 1980 to December 31, 2016. The calibrated Central Platte Integrated Hydrologic Model was used to simulate the effects of eight different potential future climate and irrigation pumping conditions from January 1, 2019, to December 31, 2049. This USGS data release contains all of the input and output files for the simulations. The user should first open the readme.txt file for descriptions on how to download this model archive and what files are contained in each .7z file.

title: Datasets of altitude of the top of the Dakota Sandstone, top of the Pennsylvanian-age units, and water-level in western Sarpy County, Nebraska

description: 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. The completed Geoscene3D project was assembled to allow Papio-Missouri River Natural Resources District managers to visualize the groundwater systems and associated water-quality results in Sarpy County and enable them to make more informed groundwater resource-planning decisions in the future.

title: Flood-inundation geospatial datasets for 14.8 miles of the Little and Big Papillion Creeks in Omaha, Nebraska, 2023

description: Digital flood-inundation map libraries for two reaches that comprise 14.8 miles of the Little and Big Papillion Creeks in Omaha, Nebraska were created by the U.S. Geological Survey (USGS) in cooperation with the Papio-Missouri River Natural Resource District. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgages Little Papillion Creek at Irvington, Nebr. (station 06610750), Little Papillion Creek at Ak-Sar-Ben at Omaha, Nebr. (station 06610765), and Big Papillion Creek at Q Street at Omaha, Nebr. (station 06610770). Near-real-time stages at these streamgages may be obtained from the USGS National Water Information System database at https://doi.org/10.5066/F7P55KJN or from the National Weather Service Advanced Hydrologic Prediction Service at https://water.weather.gov/ahps/. Flood profiles were computed using hydraulic models for two different stream reaches that comprised 14.8 miles of stream length of the Little and Big Papillion Creeks in Omaha. The models were calibrated by adjusting roughness coefficients to best represent the current (2022) stage-streamflow relation at the streamgages within the study reach. The hydraulic models were then used to compute water-surface profiles at 1-foot (ft) stage intervals at selected stage ranges to represent various flooding scenarios at the streamgages in the reach. The simulated water-surface profiles then were combined using a geographic information system with a digital elevation model, which had a 10-ft grid to delineate the area flooded and water depths at each stage. Along with the inundated area maps, polygon shapefiles of areas behind the levees were created to display the uncertainty of these areas if a levee breach were to occur. These 'areas of uncertainty' files have '_breach' appended to the file names in the data release. The availability of these maps, along with information regarding current stage from USGS streamgages, 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: Flood inundation geospatial datasets for Papillion Creek near Offutt Air Force Base, Nebraska

description: Digital flood-inundation maps for an 8-mile reach of the Papillion Creek near Offutt Air Force Base, were created by the U.S. Geological Survey (USGS) in cooperation with the U.S. Air Force, Offutt Air Force Base. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgages on the Papillion Creek at Fort Crook, Nebr. (station 06610795) and Papillion Creek at Harlan Lewis Road near La Platte, Nebr. (station 06610798). Near-real-time stages at these streamgages may be obtained from the USGS National Water Information System web interface at https://doi.org/10.5066/F7P55KJN or from the National Weather Service Advanced Hydrologic Prediction Service 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 (2021) stage-discharge relation at the Papillion Creek at Fort Crook, Nebr, streamgage. The hydraulic model then was used to compute 157 water-surface profiles for scenarios where combination of stage values in 1-foot (ft) stage intervals, that ranged between 27 and 39 ft at the Papillion Creek at Fort Crook streamgage and 13.9 and 30.9 ft at the Papillion Creek at Harlan Lewis Road streamgage as referenced to the local datum. The simulated water-surface profiles then were combined with a geographic information system (GIS) digital elevation model (DEM) with a 3.281-ft grid to delineate polygon shapefiles, and depth grids of inundated areas. Along with the inundated area maps, polygon shapefiles and depth grids of areas behind the levees were created to display the uncertainty of these areas, if a levee breech were to occur. These 'areas of uncertainty' files have '_breach' and '_breachgrid' appended to the file names in the data release. The availability of these maps, along with 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 postflood recovery efforts.

title: Water-surface and groundwater-level elevations on and near Offutt Air Force Base, Nebraska, summer 2020 and spring 2021

description: This data set contains two sets of measured water-level data collected on and near Offutt Air Force Base near Bellevue, Nebraska. Surface-water and groundwater-level data were collected for two synoptic water-level surveys completed in late summer of 2020 and in spring 2021. The elevations of surface-water features were surveyed with a rover receiver using a real-time network (RTN), where the rover receiver receives real-time position corrections from a central server through a mobile wireless-fidelity (Wi-Fi) hotspot linked to the rover receiver. Data collection procedures ensured that positions and elevations achieved a U.S. Geological Survey (USGS) Level-III survey accuracy and surveyed surface-water elevations were within 0.25 ft of published benchmarks included in the survey. Groundwater level data were collected from monitoring wells screened in the Quaternary-age deposits. During the late summer 2020 synoptic water-level survey, the elevation of the measured wells were surveyed using the RTN approach to achieve a Level-III survey accuracy. The additional data and interpretations provided with this data set and the larger data release are intended to inform stormwater managers of the effect of streamflow of the Missouri River and local climatic conditions on drainage and groundwater movement on and near Offutt Air Force Base.

title: MODFLOW models for the simulation of groundwater-flow dynamics in the U.S. Northern High Plains driven by multi-model estimates of surficial aquifer recharge.

description: There is a growing interest in incorporating higher-resolution groundwater modeling within the framework of large-scale land surface models (LSMs), including new processes such as three- dimensional flow, variable soil saturation, and surface water/groundwater interactions. Conversely, complex groundwater models (e.g., the U.S. Geological Survey Groundwater-Flow Model, MODFLOW) often use simpler representations of land surface dynamics (e.g., surface vegetation, evapotranspiration, recharge) and may benefit from higher process fidelity and temporal resolutions in these inputs. This study investigates the potential of improving groundwater representation in LSMs and land surface dynamics in MODFLOW through coupling LSMs to MODFLOW. Groundwater simulations build on an existing and well-calibrated MODFLOW model of the U.S. Northern High Plains aquifer, a hydrologically complex basin under the dual impacts of conversion of native vegetation to intense irrigated agricultural fields and climate change. As a first stage of this work, simulated groundwater recharge from four different land models are used to drive MODFLOW groundwater simulations. Results show relatively large discrepancies between recharge estimates among simulations. Forcing MODFLOW using recharge simulated by some of the LSMs in place of a simple water balance model marginally improves MODFLOW groundwater simulation. Further, our results support the efficacy of coupling LSMs to a sophisticated groundwater model such as MODFLOW. The coupling results in significant improvements in prediction of groundwater levels through correction of skewness and reduction of bias. This modeling effort seeks to identify the best compromise between comprehensive land surface processes from global LSMs and advanced representation of groundwater from regional models.

title: Environmental DNA of selected terrestrial vertebrates and bacteria detected in the Platte River near Ashland, Nebraska 2019-22

description: Water samples from the Platte River were collected and analyzed for environmental DNA (eDNA). The U.S. Geological Survey (USGS) Nebraska Water Science Center (NEWSC) collected samples monthly from November 2019 to September 2022 at the Platte River near Ashland, Nebraska (USGS: 06801000). The USGS, in cooperation with the City of Lincoln, collected these samples. Water from the Platte River was collected as a series of weighted bottle subsamples that were taken from equal width increments across the river and composited into a sterilized 1-liter bottle. An aliquot of this composited sample was extracted using a sterile syringe and then filtered by the USGS NEWSC staff using filters provided by Jonah Ventures. These filters were frozen and shipped to Jonah Ventures Laboratory in Boulder, Colorado. Any eDNA associated with 6 vertebrates (bovine, human, poultry, swine, canine, or sheep) or the Escherichia Coli bacteria were then extracted from the filter and processed using quantitative polymerase chain reaction (qPCR). These qPCR assays were chosen to identify and quantify the relative amount of eDNA for these different species that are present in the river near Ashland, Nebraska. Midway through the study effort (August 2021), a new preservative was included in the analytical method which may have introduced a step trend in some of the qPCR results. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
