If you go down osborne road you will see a small bar where 2 parts of the river reform, a nice confluence where red springs are likely to sit. Im not sure how to get to the other side, but fishing from the Osborne road side is near impossible unless you have a giant net. There is a hells angels sticker on the No Trespassing sign so I'd probably avoid trying to go down the bank and walk across. There's also a sign that says something like, "Screw the Dog, Beware of Owner!"
In any event, go down the road to Thompson Park and walk through the trail to the right, keep going and you'll eventually see a fishermens trail across a very shallow creek. Keep going through the woods and you'll hear the river roaring, follow your nose and you'll be at one of the best steelhead spots I know. It was once referred to as Shellers, and my Grandfather spoke of this spot with reverence back in the day.
It's fast moving relatively shallow water with large boulders, similar to structure around lickman/peach road and very clear, you could Fly fish with no impediment on this bar, and I bet it would be lethal for steelhead fishing. It's the first place I'm going to on December 26th.
