Summary
These data were compiled to evaluate the effects of low steady weekend flows on emergent aquatic insects during the first year of experimental Bug Flows below Glen Canyon Dam (2018) and recreation in Glen Canyon in the second year of Bug Flows (2019). Bug Flows are experimental flows that were released from Glen Canyon Dam in 2018 and 2019. The flows consist of low steady flows on weekends and have the goal of increasing aquatic insect production. These data were compiled for an outreach article providing Citizen Scientists with an update on ongoing research evaluating the effects of Bug Flows. Midge and caddisfly data were collected by Citizen Scientists using light traps. Angler data were collected under a paired sampling design [...]
Summary
These data were compiled to evaluate the effects of low steady weekend flows on emergent aquatic insects during the first year of experimental Bug Flows below Glen Canyon Dam (2018) and recreation in Glen Canyon in the second year of Bug Flows (2019). Bug Flows are experimental flows that were released from Glen Canyon Dam in 2018 and 2019. The flows consist of low steady flows on weekends and have the goal of increasing aquatic insect production. These data were compiled for an outreach article providing Citizen Scientists with an update on ongoing research evaluating the effects of Bug Flows. Midge and caddisfly data were collected by Citizen Scientists using light traps. Angler data were collected under a paired sampling design wherein each angler fished both Friday and Saturday and/or Sunday and Monday in June and August of 2019. While this data release is only a subset of ongoing data collection and analysis, it is important to provide outreach and progress updates to community partners engaged in Citizen Science powered research.
The purpose of the data are to provide a preliminary update on the effects of Bug Flows on aquatic insect production and recreation to the river running community in the greater Grand Canyon community. The majority of these data were collected by river runners participating in a Citizen Science project. While this data release is only a subset of ongoing data collection and analysis, it is important to provide outreach and progress updates to community partners engaged in Citizen Science powered research.
