Bathymetric and Water Velocity Data on the Upper St. Croix River Between Riverside and St. Croix Falls, Wisconsin, May 3–10, 2022
From May 3–10, 2022, bathymetric and water velocity data were collected on the St. Croix River between Riverside and St. Croix Falls, Wisconsin. Bathymetry and water velocity data were collected at 2 transects for 102 cross sections over the approximately 120-kilometer (km) survey reach. Longitudinal profile bathymetry transects were also collected between each cross section. These data were collected with a Teledyne RD Instruments RiverRay acoustic Doppler current profiler (ADCP) and georeferenced using two Trimble R10 Global Navigation Satellite System (GNSS) receivers (R10). Due to field site constraints (poor cell service and long distances of travel), R10 data could not be collected using a real-time network survey or real time kinematic survey. Data were collected using a post-processed kinematic (PPK) method where one base R10 was set over a known benchmark to collect static data from the beginning to the end of the survey. The other rover R10 in the boat collected raw, continuous data at a 1-second interval. The data from both the base and rover R10s were post-processed using Trimble Business Center software version 5.80 to achieve centimeter-level accuracy. The raw ADCP data were post-processed using the Velocity Mapping Toolbox (VMT) version 4.09 (Parsons and others, 2013) and the corrected GNSS data, including water surface elevations at the time of survey were merged with VMT bathymetry output files.
