Bathymetric surveys of the Colorado River collected between CO-131 State Bridge and Colorado River Road (Catamount) bridge, July 24-26, 2023

Bathymetric and topographic surveys were collected along an approximately 24-kilometer reach of the Colorado River beginning at CO-131 State Bridge and extending downstream to the USGS streamgage located near the Colorado River Road (Catamount) bridge. The surveys were collected using real-time kinematic Global Navigation Satellite System (GNSS) receivers by USGS personnel from July 24 through July 26, 2023, using a combination of sonar and wading techniques. The wading surveys include point data that are provided as comma-delimited text files of northing, easting, elevation, and code. The sonar surveys include point data that are provided as comma-delimited text files of northing, easting, bed elevation, water-surface elevation, and depth. All spatial data are referenced horizontally to the North American Datum of 1983 (2011) and vertically to the North American Vertical Datum of 1988 (NAVD88). Grid coordinates are projected in Universal Transverse Mercator Zone 13 North and are represented in units of meters.
