Summary

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 River below Glen Canyon [...]

Purpose

The purpose of these data are to model the effects of river flow regime on rates of gross primary production (GPP) in the Colorado River. The majority of these data were collected as part of long term monitoring efforts on the Colorado River, however shorter-term data from the MiniDOT oxygen loggers were collected specifically to understand the effects of an experimental flow regime on GPP. These data could be used in broader meta-analyses of aquatic GPP. We also expect the rates of GPP contained in this dataset will be used to help explain aquatic insect and fish population dynamics in the same system (the Colorado River) given preliminary work that suggests the importance of food limitation and bottom-up trophic dynamics. Finally, the relationships between turbidity and light attenuation contained in this dataset could be compared to relationships in other rivers.
