Field measurements of water depth from the American River, California, November 5-7, 2018 Field measurements of water depth were acquired from a reach of the upper American River in California, November 5-7, 2018, to support research on mapping chinook salmon spawning locations (redds) via remote sensing. 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 S5 acoustic Doppler current profiler (ADCP) deployed...
