We fished this pond frequently in the 80's and 90's, trolling streamers and hardware; we also fly fished and spin cast.
Nada, except for a few dace [chubs].
In that era, at least, Big Bog ruled in the N. Branch country; everything else was pretty much a waste of time. The exception would be some of the lower sections of the N. Branch between Snake Camp and The Ledges [and this was AFTER the drought of the early 90's which, in my humble opinion, drove trout upriver out of Seebomook] which produced some serious fish.
