Opatz, C.C., Curran, C.A., Tecca A.E., and Grossman, E.E., 2019, Stage, water velocity and water quality data collected in the Lower Nisqually River, McAllister Creek and tidal channels of the Nisqually River Delta, Thurston County, Washington, February 11, 2016 to September 18, 2017: U.S. Geological Survey data release,


An upward-looking acoustic Doppler velocity meter (ADVM, SonTek SW, 3.0 MHz) located in a tidal channel of the Nisqually River Delta at site D2 (N 47d 05’ 37.2”/W 122d 42’ 56.4”) measured water level and current velocity at 15-minute intervals from February 16 to July 20, 2017 (104 of 154 days, accounting for missing periods). This site is in a tidal channel at a levee breach where flow is tidally influenced. The water depth of the sensor ranged from 0.04 to 4.63 m and may have been lower during periods of extreme low tide. The elevation (NAVD88) of the ADVM sensor was surveyed by RTN-GPS. The offset to convert all water depth time-series data to water surface elevation (NAVD88) is 0.06 meters. Instrument temperature ranged from 4.6 [...]
