our water temps here are in the low 50's and we are finding them on ledges 10-15 feet down in 30 feet or so, yesterday I caught them 5 feet down in 17 feet of water. but the water is really muddy so once it starts to clear they will go back down. I would try mid to deep. just rig your poles to vary your depth. once you catch a few you will know what depth they are.
