Big rivers are in fact exactly like small streams, structure. flow, seams, riffles, pools and runs. You need to get to know them to find the fish. There is no one spot, they change depending on season hatches and other food sources. Spend time looking. Talk to others on the river. If you want to fast track your knowledge hire a good guide and let them know exactly what you are after (not just a float or wade). Hook up with forum members for a day out. And above all spend time the water.
