I have a lot of success catching cats and carp through the ice every winter. I usually fish areas with lots of brush along with some depth. My three usual places are Big Thompson Ponds, Barbour Ponds, and the inlet at Boyd Lake. Last year Boyd was not safe in the inlet, and duck hunters (I'm assuming that was who was shooting!) at Big Thompson ran me off. Does anyone know of good lakes with good populations of cats and carp that has underwater structure? I usually only fish the three areas listed above but am willing to explore. Most other lakes I fish during the summer doesn't offer too much underwater structure and brush.
