The U.S. Geological Survey (USGS), in cooperation with the Grand Valley Drainage District and the Colorado Water Conservation Board, conducted a loading analysis for selected constituents and tributaries to the Colorado River in the Grand Valley, western Colorado, using data from 1991 to 2018, to characterize concentrations, stream loading, and load reductions for Escherichia coli, total recoverable iron, and dissolved selenium for stream segments on the State of Colorado 303(d) list of impaired waters. Escherichia coli, total recoverable iron, and dissolved selenium concentrations and streamflow data were compiled from the Water Quality Portal (WQP). The data were submitted to the WQP by the USGS, Colorado Department...

This dataset contains cross-section surveys of the Gunnison River at Colorado Department of Transportation bridges I-04-K and I-03-A, western Colorado, 2016–17. The surveys were performed using a combination of: Trimble R8 Real-Time Kinematic Global Navigation Satellite System (RTK-GNSS) receiver, a USGS bridge crane with sounding weights, and optical levels. During surveys performed in 2016, a base was established at each bridge using the RTK-GNSS equipment. Subsequent surveys of channel geometry were performed using optical levels for ground surface observations above the water line and sounding weights for streambed observations below the water line, referenced to the base established in 2016. Streambed elevations...
