Summary

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 were interpolated [...]
