I caught that fish just below Bonneville. We launched out of "The Fisheries" launch ($10), and trolled no. 3 spinners behind flashers. Pretty much what everyone is doing there right now. We had 5 take downs with 5 anglers. Only one was landed. Mine.
I do not know how fishing has been up river, but I am still seeing lots of boats fishing in front of the mouth of The Deschutes, Klickitat, and White Salmon rivers. The boats must be there for a reason. I am guessing there are still numbers of fish around.
