The Channel has great shore fishing if you don't want to take the boat out. Fly fishing and gear fishing. Big Carp willing to take flies, large Pikeminnows and some seriously big Trout! The Trout get huge! Ive seen some of the biggest trout of my life in there. It's hard to catch them tho, Ive only ever hooked one giant. If you walk on the platform on the dam and look down into the river, you can see them in there, right under the dam. They usually hang out in a group of 2-5, a few small ones then usually a really big one in the middle. They are very selective so its tough to trick them. Kokanee are in there as well as bass. The Kokanee feed on dries before dark, so its pretty easy to pick them off. They aren't that big (10 inches). The Carp hang out in the current and will pick off leaches and I have even gotten them on dries. Just a great river to fish when you have some time to spare, usually really rewarding.
Here a video of what it looks like, I found it on Youtube. The water is high right now, as expected, but still very fishable. This guys having some fun with the Pikeminnows. Look what one of them spits out of it#s mouth!
