Invertebrate data (2012-2021) from the Colorado River in Grand Canyon and flow data (1921-2021) from the Lees Ferry gage (09380000) on the Colorado River near Page, AZ These data were compiled for an outreach article published in the Boatman's Quarterly Review, which is a magazine published by Grand Canyon River Guides Association. The objectives of our study was to describe the outcomes of the 2018-2020 Bug Flows experiment to a general audience. These data represent 10 years (2012-2021) of invertebrate data and 100 years (1921-2021) of flow data. These data were collected from the Colorado River in Glen Canyon National Recreation Area and Grand Canyon National Park. These data were collected by recreational river runners through a community science effort where we provided river runners with light trapping equipment to sample emergent aquatic insects each night of their expeditions....

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... Categories: Data; Tags: Aquatic Biology, Colorado River, Ecology, Geography, Glen Canyon, All tags...
