In 2019, the U.S. Geological Survey, in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group, studied the magnitude and recurrence interval of streamflow needed to initiate bed movement of gravel-sized and finer sediment in a segment of the Colorado River in Colorado to better understand sediment movement and its relation to flow regimes of the river. Bed movement occurred more frequently and at lower streamflows from State Bridge to Catamount Bridge compared to the study area upstream from State Bridge. Two longitudinal hydrophone profiles were carried out at different streamflows to collect underwater acoustic data using hydrophones throughout the study area on June 6-8, 2019 (June 6-8 longitudinal...

Two stationary hydrophone systems were installed on April 23, 2019 at the above Catamount Bridge stationary hydrophone site (above Catamount Bridge site), and two were installed on...

Bed movement occurred more frequently and at lower streamflows from State Bridge to Catamount Bridge compared to the study area upstream from State Bridge. Two independent and complementary lines of evidence were collected to detect incipient bed movement. Two stationary hydrophone systems were installed on April 23, 2019 at the above...

These data were compiled to improve our understanding of bat foraging along the Colorado River in Grand Canyon. Objectives of our study were to determine whether bat activity was influenced primarily by variation in prey availability relative to other environmental or geomorphic factors. These data represent 1,428 paired samples of bat activity and insect abundance calculated as catch rates collected on 611 sampling nights at 410 sampling sites throughout a 470 km segment of river. These data were collected from April to October in 2017-2020 at recreational camps along the Colorado River in Grand Canyon between Glen Canyon Dam and Pearce Ferry. These data were collected through a U.S. Geological Survey led community...
