These data were compiled to model the effects of flow regime and bed grain size distributions on rates of gross primary production (GPP) in the Colorado River below Glen Canyon Dam, AZ, USA. The objectives of our study were to quantify daily and weekly scale effects of an experimental flow regime on GPP in the Colorado River. The experimental flow was conducted at Glen Canyon Dam from May-August in 2018, 2019, and 2020 and contrasted steady-low flows on weekend days with business-as-usual hydropeaking flows during weekdays. This data release only contains data through 2019. These data represent daily-scale estimates of GPP, discharge, turbidity, water depth, and canyon shading for eleven reaches on the Colorado...

These data were compiled to describe population reproductive structure of rainbow trout in the Colorado River downstream of Glen Canyon Dam, Arizona. Objective(s) of our study were to describe the population on reproductive structure of the rainbow trout population in Glen Canyon on the Colorado River and evaluate the accuracy of nonlethal methods (manual expression and ultrasonography) for assigning sex and reproductive phase. These data represent samples collected in 3 sampling trips fall in October to November 2018, February 2019, and April 2019. These data were collected in Glen Canyon, from Glen Canyon Dam to Lees Ferry on the Colorado River. Specifically, we sampled three reaches within Glen Canyon to represent...
