Rainbows, kokanee, and them pesky northern pikeminnow is what's up there. On opening day, the catch average was 2.0 trout per person at Swift (not very big though-11 inchers or so). I have heard good reports from a neighbor and others that Merwin is producing fat kokanee up to 15 inches for trollers at about 40 feet. Haven't heard much about Yale. I don't know if the campgrounds are open up there yet though, I don't think they are?
