I have always found big LM were easier to catch in other BOW when it's colder-Feb./March. I didn't catch large numbers but the fish were considerably larger. As it warmed May/June the large fish just didn't bite as well. It seems in my pond that the fish have become hook shy, sometimes switching to something different they haven't seen in awhile helps. But I'm also a big believer in moon phase too. If the phase isn't right I just don't catch as many fish, if any at all.
