Resource Abstract:
- description: Between the years 2000 and 2016, scientists and technicians from the U.S. Geological Survey (USGS) Columbia Environmental
Research Center (CERC) have collected over 400 field-days worth of acoustic Doppler current profiler (ADCP) measurements on
the Missouri and Yellowstone Rivers, primarily for the purposes of assessing physical aquatic habitat for the pallid sturgeon.
Scientists and technicians collected data using boat-mounted Teledyne Rio Grande ADCPs, which were processed using customized
scripting tools and archived in standardized formats. To assess longitudinal variability in depth and velocity distributions
along the Missouri River, as well as compare the Missouri River to its unaltered analog, the Yellowstone River, we compiled
the collected datasets into a single comma-separated value (csv) file using a series of data-processing scripts written in
Python. To allow for the comparison of measurements collected only within a specific window of flow exceedance, we conducted
geospatial analyses to attribute each ADCP measurement by a discharge from the most relevant USGS gage location (with the
most relevant gage location being the gage located between the same major tributaries as the measurement, even if it was not
the closest spatially), and assigned each measurement a flow exceedance percentile based on the relevant gage's record
between 2000 and 2016. We also conducted general quality control on the data, discarding any ADCP returns where the ADCP measured
a depth-averaged velocity greater than 3 meters per second or a depth greater than 16 meters; these values were considered
to be an approximate upper bounds for realistic values on the Missouri and Yellowstone Rivers. The presented csv file lists
individual ADCP bins for all measurements that have been archived between 2000 and 2016 by CERC scientists along with their
three-dimensional velocity components, depth-averaged velocity magnitude for a given ADCP return, average channel depth for
a given ADCP return (computed from four ADCP beams), and fields to classify the data by river location and flow exceedance.;
