Summary

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length. First, we linked reservoir storage capacity and dam size to the warmest monthly water temperature per water year (WY) to assess the influence of low storage capacity (shallow reservoirs) on downstream water temperature. We then took results from previously published Generalized Linear Mixed Models (GLMM) that assessed the influence of physical and biological predictors (e.g., flow, trout density, reservoir metrics) on trout recruitment and adult size and added mean annual, maximum annual, and minimum [...]

Purpose

We obtained fishery monitoring data from state fishery management agencies that conduct research in tailwaters throughout the western US. These data included rainbow and brown trout adult size and the catch per kilometer of sub-adult fish (i.e., recruitment). These data were paired with physical and biological variables including water temperature, flow, reservoir attributes, and fish density to parse out the importance of water temperature relative to other variables on recruitment and the size structure of tailwater trout populations. We found that water temperature was a more important predictor of recruitment processes than adult size, but that density-dependent growth constraints could exacerbate temperature-dependent growth reductions. As such, these data and the resulting analyses could inform management of tailwater trout populations in a warmer and drier climate.
