You probably have a fish/depth finder?
Looking at Google Maps (never been there), I would recommend either the Southeast portion of the lake, or a deep area close to a drop-off in the West section of the lake. Use a stocker Trout fillet for bait, Emigrant gets stocked right? Those Channels will be very used to eating them.
I would atleast use this advice if I went to the place and had a boat and little info on known whereabouts of the fish.
