only fished LOZ couple times, but that lake like any lake can be a bummer to figure out, just keep doing what your doing, but one thing I have learned fishing in the cool mounts is fish are more shallow in the am and a little deeper in the afternoon, we been finding fish in 11ft.of water or less, some on brush some just scattered out on the flats next to a creek channel. I just been trolling arround looking for balls of shad, find the bait and the eaters will be close, seems like the crappie will move in and out of deep water so if they are not deep look shallow, I have and often caught them up in 2 ft. of water casting to the bank, they would be right on the grass looking for the snails,worms,and small shad, you can watch the grass wiggle and pitch a jig and bam, so keep looking and reading.
