The second, to largest LMB I've ever caught, I caught while living in North Idaho, in the middle of winter. I was trout fishing a small lake's outlet stream........ fast moving water, 2-3 feet deep, over a rocky bottom.
It was cold, (below freezing out and snowing at the time), 90% of the lake was frozen over, except close to where I was fishing the outlet creek.
All the "facts" put together....... snowing, below freezing air temp, fast water, small creek..... just didn't "add up" to any reason that a Large Mouth Bass would hit a green Wooley Bugger!?. Not, from my own LMB fishing experiences, anyway!
But, he did and I did and we did and he netted at 21" and 5 pounds. Sure shocked me, at the time and I still can't imagine catching a Bass, of that size, in a perfect "trout water" situation!
But, like Micro mentioned....... "They have to eat, all winter long, just like everyone else!?!
