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...

A vented water-level logger was installed at site MC1 (N 47° 05’ 12.2”/W 122° 43’ 36.8”) and continuously measured water depth and temperature at 15-minute intervals from Nov 22, 2016 to Sept 6, 2017 (288 days). This site is tidally influenced and located 1.12 km from the mouth of McAllister Creek. Elevation (NAVD88) of the water surface above the sensor was surveyed by RTN-GPS. The offset to convert all water depth time-series data to water surface elevation (NAVD88) is -1.052 m. Water depth ranged from 0.69 to 4.88 m. Temperature ranged from 2.8 to 22.5 degrees C.

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 D1 (N 47° 05’ 37”/W 122° 43’ 17”) measured water level and current velocity at 15-minute intervals from October 14, 2016 to May 31, 2017 (175 days, excluding 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 0.44 to 4.41 m. The elevation (NAVD88) of the ADVM sensor was survey by RTN-GPS. The offset to convert all water depth time-series data to water surface elevation (NAVD88) is -0.61 m. The water temperature ranged from -0.4 to 22.7 degrees C but may have been bias during periods...

Two sensors, a vented conductivity, temperature and depth sensor (CTD) and a turbidity meter, were installed on a piling at the mouth of McAllister Creek at site MC3 (N 47° 06’ 01”/W 122° 43’ 36”) and connected to a telemetered data collection platform that was used to program, power, and log data for each sensor. Timing of the 15-minute sampling interval was synched among both sensors. The site is tidally influenced. The CTD (InSitu Aqua Troll) measured water temperature, water depth, specific conductance, and salinity from December 24, 2016 to February 17, 2017 (55 days). Water depth ranged from 0.52 to 5.49 meters. Temperature ranged from 1.1 to 9.8 degrees C. Specific conductance ranged from 5,500 to 43,100...

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 D4 (N 47° 05’ 37”/W 122° 42’ 18.7”) measured water depth and current velocity at 15-minute intervals from October 13, 2016 to May 3, 2017. This site is in a tidal channel at a levee breach where flow is tidally influenced. The water depth of the sensor ranged from 0.19 to 3.71 m and may have been lower during periods of extreme low tide. The sensor elevation was adjusted during inspection on 10/03/2017 and a correction of +0.33 m was added to water depth from 10/03/2017 to 03/13/2017. The elevation (NAVD88) of the ADVM sensor was survey by RTN-GPS. The offset to convert all...
