By midsummer, lakes are full of feed. The biggest bass gather in schools in places where choice food is easiest to catch. You want to identify these spots. First, look for dropoffs, where rocky reefs or points fall off into 15 to 25 feet of water. Smallmouths also gather along reefs to forage for crayfish, and they gang up in 10 to 15 feet of water close to weedbeds, where frogs and baitfish hide. At midday, big bass often congregate where old river channels carve into lake bottoms. Once you know where these bait-attracting features are found, you're on your way to finding large bass.
