Paul Stumpner Trevor Violette Marc Inc 20250502 spreadsheet https://www.sciencebase.gov U.S. Geological Survey data release https://doi.org/10.5066/P9UN3IMK Moving boat (MB) acoustic Doppler current profile (ADCP) measurements collected at discrete cross-sections over an ~1.5 kilometer stretch of False River, near the San Joaquin River, CA. These data were collected on four separate days in March of 2022, and are georeferenced and depth-averaged. Side looking (SL) ADCP data was also georeferenced to provide an index for the moving boat ADCP measurements. Collectively these data sets are used to document velocity patterns from a notch in a rock barrier that was installed in False River. The velocity maps from the MB-ADCP measurements are indexed to the SL-ADCP data in order to infer velocity patterns over a larger temporal range. These indexed velocity maps are then used as a covariate for fish predation analysis. 20220222 20220330 ground condition Complete None planned False River -121.68182 -121.65264 38.06539 38.04647 ISO 19115 Topic Category biota USGS Thesaurus acoustic doppler current profiling None velocity mapping USGS Metadata Identifier USGS:64f7a6c3d34ed30c20545135 Geographic Names Information System False River, Contra Costa County, California Sacramento-San Joaquin Delta, California None.

No formal positional accuracy tests were conducted No formal positional accuracy tests were conducted Raw data MB-ADCP data was collected with WinRiver II. Data was QA/QC'ed in WinRiver II, by inspection of collection parameters and graphical inspection of data files. These data were collected, reviewed and processed in accordance to methods and standards of Mueller et al., 2013. Raw data was processed using velocity mapping toolbox (VMT) version 4.06. Repeated transects at a river cross-section were averaged into a single velocity profile for that location. Parameters used in processing with VMT. Horizontal grid spacing of 1 m, vertical grid spacing of 0.25 m, horizontal smoothing window of 3, and vertical smoothing window of 3. These methods are also outlined in Parsons et al., 2013. 20220401 SL-ADCP data was collected at the USGS gage station 11313440, False R NR Oakley CA. These data were collected in accordance with methods from Levesque and Oberg 2012. Normally the water velocity data is stored as an average for the river cross-section, every 15 minutes. For this study we wanted to examine finer temporal and spatial resolution, so we collected data at every location along the river cross-section, a total 34 bins every minute, and this data is included in the data release. 20220401 Both MB-ADCP and SL-ADCP processed data files were compiled and exported to .xlsx files using Matlab 20220401 Point Point Universal Transverse Mercator 10 0.9996 -123 0 0 0 coordinate pair 0.01 0.01 meters YYYYMMDD_#_Depth-Averaged Velocities Time, Location, Distance, and East and North Velocities Producer Defined First Row The first row contains two cells that represent time range of the measurements Producer Defined DD-MMM-YYYY hh:mm Easting [m] UTM (Universal Transverse Mercator) Easting coordinate Producer Defined 616156.45 617438.5 meters 0.01 Northing [m] UTM Northing coordinate Producer Defined 4212794.96 4213371.97 meters 0.01 Distance Along Cross-Section [m] distance along cross-section Producer Defined 0 318 meters 1 East Velocity [m/s] east component of velocity, positive values are towards the east, negative values are towards the west Producer Defined -1.61 1.8 meters per second 0.01 North Velocity [m/s] north component of velocity, positive values are towards the north, negative values are towards the south Producer Defined -1.3 1.04 meters per second 0.01 SLACDP_1minVelocities 1min data of individual bins of X-Y coordinate velocity data from the SL-ADCP.
