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 47d 05’ 37”/W 122d 42’ 18.7”) measured water level and current velocity at 15-minute intervals from October 13, 2016 to May 3, 2017 (158 out of 202 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 0.19 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 water depth time-series data to water surface elevation (NAVD88) is -0.18 meters. The instrument temperature ranged from -0.4 to 15.9 degrees C. but may have been bias during periods of low tide due to solar heating of the instrument. Water level in the channel dropped below the elevation of the sensor during periods of low tide. The mean downstream velocity component (Vx) ranged from -0.91 to 1.07 m/s. The mean vertical velocity component (Vy) ranged from -0.20 to 0.26 m/s and signal to noise ratio ranged from 17.6 to 50.4 dB. The ADVM measured the water-velocity profile using a dynamic boundary adjustment mode allowing up to 10 velocity measurements in the water-column profile. Time-series gaps of 15-minutes or more occurred when the instrument was offline or when error thresholds were exceeded. Also at this site, a non-vented, multiparameter sonde (YSI, 600 OMS) measured water depth, water temperature, specific conductance, salinity, and turbidity at 15-minute intervals from October 12, 2016 to March 31, 2017 (123 out of 170 days, excluding missing periods). The depth ranged from 0.06 to 3.66 m. The water temperature ranged from -0.3 to 16.1 degrees C. The specific conductance ranged from 160 to 38,850 micro-siemens per centimeter (uS/cm), and 0.1 to 24.7 practical salinity units (PSU).

Multiple sensors for measuring stage (water level), water temperature, specific conductivity, turbidity and water velocity were installed at site NR2 (N 47d 04' 46.1"/W 122d 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, 2017 (190 days). Water temperature measurements ranged from 1.8 to 19.9 degrees C. Water depth of the the sensor ranged from 0.08 to 4.73 meters. Water surface elevation (NAVD88) was surveyed with RTN-GPS at the same time as water level was measured and recorded by sensors and was used to determine an offset (-0.44 m) for converting water depth to water surface elevation (NAVD88). Specific conductance measurements ranged from 48 to 43,217 microSiemens per centimeter (uS/cm) and salinity ranged from 0 to 27.81 practical salinity units (PSU). Data gaps of 15-minutes or more were reported an “NA”. Missing data from May 24, 2016 to June 1, 2016 was the result of DCP failure. The deployment pipe was hit by debris on March 16,2017 which ended the deployment. An acoustic Doppler velocity meter (ADVM, SonTek-SL 500) measured water temperature, stream velocity and signal-to-noise ratio (SNR) from May 11, 2016 to August 3, 2016 (85 days) and from September 8, 2016 to March 16, 2017 (190 days). Water temperature measurements ranged from 2.0 to 19.7 degrees C.

This U.S. Geological Survey data release consists of multiple datasets used to simulate the streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch near Rox, Nevada. Streamflow extents equal the maximum area of flow inundation and were estimated using a two-dimensional (2D) hydraulic model. The modeled extents represent baseflow and six annual exceedance probabilities simulated for the current (2021) topography and modified topography associated with possible restoration of Stuart Ranch along Meadow Valley Wash. The data release includes: 1) a zip file containing a shapefile of a polygon dataset of the streamflow-inundation extents (Stuart_streamflow_extent.shp); 2) a zip file containing all raster datasets of streamflow depth (Stuart_Depth.zip); 3) a zip file containing all raster datasets of streamflow velocity (Stuart_Velocity.zip); 4) a zip file containing all relevant files to document and run the PeakFQ flood-frequency analysis used as input into the hydraulic model (09418700_Stuart_Flood_Frequency_Archive.zip); 5) a zip file containing all relevant files to document and run the 2D Hydrological Engineering Center-River Analysis System (HEC-RAS) hydraulic model used to generate a polygon dataset of streamflow-inundation extents (Stuart_SWmodel_Archive.zip); 6) a zip file containing a raster dataset of a digital elevation model (Stuart_DEM.tif) derived from survey points; 7) a zip file containing two polygon datasets of the restoration modifications used in conjunction with the Stuart_DEM to model possible restoration conditions (Beaver_Dam_Modification.shp and SideChannels_IrrigationDig_Modifications.shp); 8) a zip file containing a point dataset of survey points (SurveyData.shp) collected from December 14, 2020 to January 11, 2024, using real-time kinematic global navigation satellite system (GNSS), static GNSS, total station (TS), manual entries, and filtered ground observations from TLS surveys; and 9) a point dataset of lidar points (Stuart_Raw_TLS.las) collected at 44 scan locations by TLS surveys.

Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; and (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD). Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers).
