Fig. 2. Comparison of movement of 100 NFS virtual emigrants [A] and 100 passive particles [B] released 700 m upstream of Lower Granite Dam. Virtual emigrant and particle tracks are yellow. Note the pattern of behavior changes as the virtual fish approach the dam (inset plot in [A]). Upstream of the dam, the default behavior B 0 dominates, but the other behaviors become more dominant as the hydrodynamic environment becomes more complex near the dam (inset to [A]).
