This river seems a bit much if you're just starting up. I highly recommend visiting your nearby
Junction City Pond since they've been stocking it for months, and will get a few more truckloads this year, and you can bring your kayak or pontoon.
Here's a
Power Bait rig that most anyone at the pond would be happy to help you set up. If you're on your kayak, feel free to go crazy with spinners or a fly.
Again, do not try going in the McKenzie without a professional guide. You will get trapped in a current and drown. The pond, less of a chance of that, and you can take your kayak out (wear a life vest).
