It should be pretty good, especially with the cooler spring which we've had this year.
I've never done really well out of Hicks. They stock it with trout and it gets fished out through the summer so big ones are pretty rare.
Its pretty though and good swimming.
I've found the opposite actually. There isn't enough pressure to fish the stocked catchable rainbow trout out each season. There are always fish that manage to survive for a year or two, and they get quite big too. Around 8 years ago we had a pretty mild winter, and I, as well as Nick, separately, managed to get the boat in there for a few days in February. We got into rainbows up to 20 inches, and he broke a big cutthroat trout off.
The last few years I've found it to have a higher abundance of smaller fish, especially the cutthroat trout and kokanee. I went once this spring and caught more kokanee than trout.
Back to OP's question. The best approach would be to fish close to the bottom with bait.
