Cross-section geometry and sediment-size distribution data from the Upper Colorado River, April 6-8, 2022

The U.S. Geological Survey collected geomorphic monitoring data in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group. This data release contains cross-section geometry and sediment-size distribution data collected from five sites on the Upper Colorado River, Colorado during April 6-8, 2022. The five sites selected for monitoring were located at the Pumphouse Recreation Area, Radium Recreation Site, State Bridge, above Catamount, and below Sweetwater Creek. A cross section was surveyed at each site using real-time kinematic Global Navigation Satellite System survey methods to document the channel geometry. All five cross sections are incorporated in this data release and presented in CSV files, with one file for each monitoring site. Pebble counts were performed at each of the five cross sections to document sediment-size distributions. All the sediment-size distribution data are presented in CSV files, with one file for each monitoring site.
