This dataset contains base-flow recession time constant (tau) contours that are interpreted from tau values calculated at streamgages in the Niobrara National Scenic River study area. The contours were created by interpolating the calculated tau values using geostatistical kriging methods. 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, and (2) in the development of regional low-flow regression equations. The Geostatistical Analyst tools in ArcGIS Pro...

The High Plains aquifer extends from approximately 32 to 44 degrees north latitude and 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital dataset consists of a raster of water-level changes for the High Plains aquifer, predevelopment (about 1950) to 2019. It was created using water-level measurements from 2,741 wells measured in both the predevelopment period (about 1950) and in 2019, the latest available static water level measured in 2015 to 2018 from 71 wells in New Mexico and using other published information on water-level change in areas with few water-level...
Digital flood-inundation polygon shapefiles 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 High Plains aquifer extends from about 32 degrees to almost 44 degrees north latitude and from about 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set is comprised of water-level measurements from 7,698 wells measured in both 2015 and 2017, which were used to map water-level changes, 2015 to 2017. The map was reviewed for consistency with the relevant data at a scale of 1:1,000,000.
This data set contains two sets of water-level contours that represent interpreted water-levels for an area between the Platte and Elkhorn Rivers just above their confluence. The contours are informed by surface-water and groundwater-level data collected during the fall of 2016 during synoptic water-level survey completed during a low-groundwater demand period and a summer 2017 synoptic water-level survey completed during a high-groundwater demand period. The additional data and interpretations provided with this data set and the larger data release are intended to inform water managers of the effect flow conditions on groundwater movement and interaction with surface-water above the confluence of the lower Platte...

This data set contains two sets of measured water-level data collected in an area between the Platte and Elkhorn Rivers just above their confluence. Surface-water and groundwater-level data were collected during the fall of 2016 during synoptic water-level survey completed during a low-groundwater demand period and a summer 2017 synoptic water-level survey completed during a high-groundwater demand period. The elevations of surface-water features were surveyed with a rover receiver using a real-time network, 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...
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. The magnitude of tau indicates the degree of hydraulic conductivity of the stream to the groundwater system. Larger tau values indicate a stronger dependence on the groundwater system for streamflows, a smaller base-flow recession value indicates that the stream is not as dependent on the groundwater system for streamflows. 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...

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)...
