Good to hear you got out there Griz! LOZ is a tuff nut to crack, I admit that whole hardheartedly. But, once you find you a brush pile you can bet they are on it. Between LOZ and Truman and Stockton and Pomme reports I think the average depth the fish are found in is around the 20 + foot mark of total water depth, and in some areas deeper with the fish suspended up in the 12-18 foot range. So that will give you an idea of where to look.
2 weeks ago I fished about 4 hours in water at about 20 foot on LOZ and they were up in the 15 foot range of water. Never got on a good number of them, and caught several small ones, but when you caught a legal fish it was healthy and heavy.
Bugman will steer you right. Good luck out there bud.
