The easiest way I’ve found to get a bead on deep fish is to see them aggressively surface feeding on baitfish. Over the years, I’ve come up with a few ways to catch these fish once they go down, which is inevitable. They may stay up for ten minutes or ten seconds, but when they dive, a minnow-colored bucktail jig or blade bait are good choices because they have action on the fall, and that’s when they’ll get hit. Whenever I encounter this situation, my hope is to find the school on the surface more than once throughout the summer, and to that end I’ll keep checking. Sometimes—but rarely—you can luck into a deep spot that produces with some level of consistency. What keeps them there could be any number of things from deep structure that touches the thermocline to a remote deep current, but if you find repeat action, there is something attracting them. Since it’s often hard to pinpoint whether or not the fish you found are just passing through a deep area or will set up there again and again, catch as many as you can when you find them. Deep water often produces heavyweights.
