Summary

This dataset includes a georeferenced mosaic of high-resolution, aerial thermal infrared (TIR) images of the lower Elkhorn River, Nebraska, presented as a gridded (raster) image in GeoTiff format as well as a reach centerline of the lower Elkhorn River within the TIR imagery boundary. 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 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. The reach centerline was manually digitized within [...]

Purpose

Aerial thermal infrared (TIR) imagery was collected during a low groundwater demand period in December of 2017 to assess the spatial variability of the lower Elkhorn River. A reach centerline was manually digitized in a GIS in order to extract temperature data from the TIR imagery. Temperature data were plotted against distance along the centerline to create a downstream temperature profile which was used to interpret groundwater discharge patterns. The additional data and interpretations are intended to inform water managers of the affect flow conditions on groundwater movement and interaction with surface-water above the confluence of the lower Platte and Elkhorn Rivers.
