Im surprised no one has mentioned plunking, especially for the winter.
When it's cold and you dont feel like doin' a lot of casting, just plunk!
Here's how you rig with a spreader-- 15 lb main line, goes to a spreader with the strongest knot you know. 3.5 ft Leader-12 lb line with a spin n glow, 2 6mm beads, and a size 2 or 1 hook. Toss on some eggs or shrimp.
For the dropper end, enough weight to hold the whole rig down. 6 oz is enough for most rivers. Don't cast too far, fish hold near the bank during winter when the water is dirty
If you dont have spreaders, thread a barrel swivel onto your mainline. After the swivel, slide on a 6-8 mm bead. On the end, tie on another swivel. Tie your dropper line to the swivel on the end. Tie your leader with the spin n glow to other.
Dropper line lengths depend on the type of river bed. Boulders call for longer ones. Pebbles call for smaller. For the clackamas and willamette, 16 inch droppers should do fine.
Cast out 15 feet or so, then go wait in your car!
