Walked up to the holding pond on the Sol Duc one time and noticed it was plugged with summer coho. Included with them were two summer run steelhead. I had some shrimp on me so I tossed one in the pond. One of the summer run tore through the silvers and engulfed it. I tossed in another and watched the second one do the same thing. Any question about summer runs feeding was answered then and there. They acted as if they were starving from being trapped in the pond.
