Used to do it on one of the more southern kawartha lakes until it turned into a free for all, basically the area was fished out. I tried it on the lake I live on once and did okay, but could never repeat it. I'm talking crappie. Perch can be found in schools along weed lines, just have to find a nice day to be able to work it properly. Temp is mid to low 50's if not less.
