Airborne thermal infrared imagery and longitudinal stream temperature profiles, Hat Creek, California, August 2018
A public data release by Jennifer Curtis and other USGS scientists has been published. The data release features airborne thermal infrared imagery and longitudinal stream temperature profiles and is part of a USGS study to assess spatial patterns of groundwater discharge.
Hat Creek is a tributary to the Pit River located in northeastern California. Discharge from cold-water springs contributes ~10% of the average annual flow to the Pit River, which flows into Shasta Reservoir and represents an integral component of the Central Valley Project and California’s surface-water supply. This dataset includes georeferenced high-resolution, airborne thermal infrared (TIR) imagery, a polyline shapefile of the channel centerline, and a tabular file with longitudinal stream temperature profiles for Hat Creek, California. The two aerial TIR surveys were conducted with a helicopter by NV5 Geospatial (formerly Quantum Spatial, Inc.) and are published as two raster mosaics in GeoTiff format. The TIR dataset encompasses a 64.6-km reach of Hat Creek that extends from 50 m upstream of the confluence with Lost Creek to 50 m downstream of the confluence with the Pit River. The TIR surveys were collected during the afternoon of August 24, 2018, and the morning of August 25, 2018. The intended uses of these data include, but are not limited to, assessments of thermal heterogeneity, sources of cold-water discharge, and geologic controls on surface-water and groundwater interactions within the Hat Creek basin.
