It is very deep, has plenty of food and fishing pressure from May to August only. Fishing here was bad during the drought of the mid-eighties, but we were able to map out the bottom, and learn where all the deep water is. Now that it is full each summer, we try going to that deep water just to see what will happen. Nothing has so far. But we also learned where the creek-beds are that used to wind their way down the river bottom during the drought.
Big fish hang out in the troughs, and the fish-finder has repeatedly given back some huge images.
We troll, offer live bait, we hit them on top of the head with a glob of salmon eggs, and they just don't like what we're serving, evidently. They must know we are there. The big ones are hard to catch. The back country packer listed below has no website, but is excellent. They feature all day fishing trips into the Kaiser Wilderness and overnight fishing trips into the high country where ever you want to go.
