Lots of Laker's in Tiber, seen them thru the spear hole and catch them on walleye rigs with tip up's all the time. Had one on two weeks ago that was an absolute pig, made four full runs on my line and the hook popped of the jaw at the bottom of the hole. I have caught several in the 10 to 17lb range, not my favorite fish to eat but if you smoke them they are tasty. Good luck!
