A vented conductivity, temperature and depth sensor (CTD, InSitu Aqua Troll) was installed at site NR1 (N 47° 04’ 16.1”/W 122° 42’ 15.5”) and continuously measured water temperature, water depth, specific conductance, and salinity at 15-minute intervals from February 11, 2016 to July 18, 2016 (159 days). The sensor was replaced with a vented water-level logger (InSitu Level Troll) on July 19, 2016 and deployed until March 19, 2018 (608 days). The site is tidally influenced and located approximately 4.1 km upstream from the mouth of the Nisqually River and within the tidal prism. The elevation (NAVD88) of the top of the deployment pipe was surveyed by RTN-GPS. Tape-down measurements from the top of the pipe to the...

An upward-looking acoustic Doppler velocity meter (ADVM; Sontek XR, 1.5 MHz) was deployed in McAllister Creek at site MC2 (N 47° 05’ 43”/W 122° 43’ 38”) and continuously recorded water velocity, temperature and water level at 5-minute intervals from September 26, 2016 to October 14, 2016 (18 days), and at 15-minute intervals from December 2, 2016 to May 25, 2017 (174 days) except for the period of March 6 – 11, 2017 when the sensor was removed for maintenance and battery replacement. The site is tidally influenced and located approximately 0.7 km upstream from the mouth of McAllister Creek. The measurement averaging interval for the ADVM was 60 s. The blanking distance was set at 0.5 m and the cell end was set at...

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.

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...

Discharge and suspended sediment data were collected from October 2016 to Febuary 2017 at the NR0 site. Data was collected immediately down stream of Old Pacific Hwy SE bridge during a bridge measurement and approximately 100 meters below bridge for a boat measurement. Data collection from the bridge has been ongoing since 1968 but data collection from a boat was first attempted October 21, 2016 during this data collection series. Suspended sediment sample and discrete discharge data at this site are available at: https://waterdata.usgs.gov/wa/nwis/inventory/?site_no=12090240&agency_cd=USGS&. A summary of suspended-sediment sample data are provided with this data release in the file NR0_SSC_summary.csv.

Multiple sensors for measuring stage (water level), water temperature, specific conductivity, turbidity and water velocity were installed at site NR2 (N 47° 04' 46.1"/W 122° 42' 30.2"), located approximately 3.1 km upstream from the mouth of the Nisqually River and within the tidal prism. The sensors were connected to a cell-phone telemetered, data collection platform (DCP) used to program and power each sensor as well as synchronize the timing of 15-minute measurement intervals. A vented conductivity, temperature and depth sensor (CTD, InSitu Aqua Troll) measured water temperature, water depth, specific conductance, and salinity from May 11, 2016 to August 3, 2016 (85 days) and from September 8, 2016 to March 16,...

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...

GPS horizontal and vertical position data were collected on the Nisqually River, McAllister Creek and Nisqually River Delta to survey in water surface, instrumentation and delta structures for to reference North American Vertical Datum 1988 (NAVD88). These data are housed in .csv file named “Nisqually GPS Data” and are sorted by date and time. The position data are grouped by data collection methods Point and Topo. Point method collected position data for 180 seconds and was used to survey surface water and instrumentation elevation. Topo method collected position point data for 1 second and was used for surveying delta bathymetry elevation. Data were collected using the available RTN-GPS network provided by the...
