These data are the primary data used to model rainbow trout growth in Glen Canyon. Fish growth data were collected from nighttime boat electrofishing field campaigns conducted five to six times per year in April, July, September, and January, from April 2012 through November 2021 for a total of 9798 observations of mark-recapture-based growth. Sampling was conducted in a five km reach in the lower portion of the Glen Canyon tailwater (3.7-8.9 km upstream of Lees Ferry, AZ). Two nights of sampling occurred on each trip, with the central 2-3 km of the reach sampled on both nights. After capture, fish were kept in aerated 40-L buckets and transported to a central processing location. Groups of 10-15 fish were anesthetized...
These benthic macroinvertebrate data and associated site characteristics were compiled for the purpose of exploring any relationships between large dams in the Colorado River Basin, their flow management and geographical context, and their associated downstream benthic macroinvertebrate communities. The goal of the analyses based upon these data was to understand how dam conditions, specifically hydropower fluctuations for hydropower generation ("hydropeaking") might influence the structure of benthic macroinvertebrate communities, and how this community structure may change with distance downstream from each dam. These benthic macroinvertebrate samples were collected in spring 2015 by scientists from the U.S. Geological...

This data is a compilation of fishery monitoring data collected by state agencies over several decades in tailwaters downriver of dams in Colorado, Utah, Montana, Wyoming, Idaho, New Mexico, Arizona, California, and Oregon. Specifically, the data contained herein is summary data used in four generalized linear mixed models that were developed to assess the biological and hydrologic factors that influence rainbow and brown trout recruitment and adult size in tailwaters across the western United States.

The data contained in this workbook were compiled to investigate the relationship between hydrology of the Colorado River and ecosystem metabolism parameters (i.e., primary production and ecosystem respiration). The workbook contains data exploring the link between Colorado River discharges and water velocity, which are depicted in figure 2 of the associated manuscript. The workbook also contains data pertaining to calibration of the hydraulic model used for modeling discharge and metabolism, and these data are depicted in figure 3 of the manuscript. Also contained are data pertaining to air-water gas exchange rates (k600) that were estimated from the coupled hydraulic model (from figures 4 and 5 of the manuscript)....
