The perch seem to be just about anywhere on the lake, I was getting them deep around 44 feet but that was the deepest water around on a big mud flat, Heard guys doing well over at sand mesa and trout bay. For the ling not sure we caught one during the derby but it came through where we were catching the perch. I know others that have been catching the perch in 22 feet or less. I have had most my flags in 5 feet or 44 feet of water nothing in between, but have not been out since the derby. If you want to just catch a bunch of perch stop by bass lake on the west side of the lake and drill until you find out where they are, just no live bait on this lake but always a good day for the kids to jig a bunch up.
