GLM estimates of (A) length vs. site by year for ERT, WRT, and Percichthys trucha, the latter with sites not differentiated (factor not present in its final model), (B) SMI vs. site by year for WRT and P. trucha, and (C) length vs. depth by site for P. trucha and SMI vs. origin of rainbow trout (escaped/wild). Bars and ribbons represent 95% confidence intervals. Additional ticks indicate sampling depths.
