The fish are spread through the entire system. I personally like fishing the upper river where it is a challenge to catch fish. You can catch the fish by drifting with or without a bobber, and spinners are working to. Behind Taco Time in Pendleton is a very good hole, in Pendleton. The river is a shallow with a few deep holes. 2600+ fish in the system now. 1100 in 11 days came in. It is stacked. good luck, i am taking my brother out this evening. Have to go, good luck and i am sorry i can not be much more help at this time. Steve
