Ok try going for the shallows first, if you don't catch anything there should be signs the fish are there, like them scattering off or something of the sort. Then go the the deep water, if they aren't there either try the middle depth. The whole time switch lures often, but preferably fish the faster baits (like a TT) to find some fish or slowly move a glide through there to find followers (250 is a great option). At first in those water depths hit the most common things, like points, secondary points, and ledges or drop offs. If you can't find them in those basic spots try finding what the fish are relating to, weather it be wood, grass, or pads and fish that pattern hard. Try running spots of similar stuff if the bite dies down in a given area. Once you find them slowly dissect the water with a slow moving bait, like a hudd or a hard gill fished slow. I can't wait to see what you catch!!!
