Yes, Jumbo perch are biting just about anywhere these days it seems. The deeper structure say 20-30 feet seems to be holding the better numbers. The perch are really concentrated in areas and they are dandies. Yesterday we boated 50-75 perch that were all over the 11 inch mark, man mix that in with some 30-40 walleyes and thats a pretty good day of Mid-July fishing.
