Not many Bass fisherman on this site, we used to fish that lake years ago for Bass. I can give you a few rough areas. Coming out of the river from Laconia there is a small island on your right, a few hundred yards off that Island there is a hump that holds Smallies quite often.
Going up the west shore, about 1/2 way up the lake in close there is a house with big porch with white ballisters, fish between the rafts in front of this house, nice largemouths.
Then allmost to the furthest north end of the lake, again on the west shore there is a little house on its own island a few feet from shore, cant miss it. Fish that shoreline around and south of the little house for nice mix of small and large mouths. The lake is real narrow at this point and both shore lines hold fish.
There is one other spot that holds big largemouths that I know of, at the extreme south end of the lake, the river going out holds lots of nice fish, huge Bass. We always saw them there but could never get a strike, lots of sunken tree branches, etc. along the shore ???????
Sorry but that is the best I can do from memory, been at least 10 or 15 years since I fished where I described.
