Field measurements of water depth were acquired from a reach of the upper Sacramento River in northern California, September 12-14, 2017, to support research on salmon habitat and geomorphic change along the Sacramento River and, more broadly, remote sensing of rivers. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the water's edge and bed elevations within the channel; depths were calculated by subtracting bed elevations from the nearest water surface elevation. For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor...

This data release includes the input topographic data sets, model parameters, and validation field measurements of flow velocity used to develop and test multidimensional hydraulic models for a reach of the upper Sacramento River in northern California. Digital elevation models (DEMs) were developed by combining water depth maps of the reach, created using spectrally-based remote sensing methods, with light detection and ranging (lidar) data on water surface and terrestrial elevations. The depth maps were derived from three imagery sources: (1) airborne hyperspectral imagery (CASI); (2) uncrewed aerial survey (UAS)-based hyperspectral imagery (Nano); and (3) multispectral satellite imagery (WV3). The methods used...

The Baca National Wildlife Refuge is located in the San Luis Valley of South-central Colorado on the western flank of the Sangre de Cristo massif, northwest of the Great Sand Dunes National Park. Wildlife managers at the refuge are tasked with protecting two fish species of special concern, the Rio Grande Chub (Gila pandora) and the Rio Grande Sucker (Catostomus plebeius). The U.S. Geological Survey (USGS) collected surface water data with Stream Temperature, Intermittency, and Conductivity (STIC) instruments deployed at the Baca NWR from 2016–2019. STIC instruments are unique for this type of investigation for the purpose of simultaneously collecting temperature data and an electrical resistance signal to determine...
