Crystal Lake Gilmanton. The launch is so so . A smaller 14' or 16' boat would be max. You launch in a channel. And at times there is a pretty good water flow. I believe the channel to the lake is 5' deep. The fishing is generally slow. But you should catch some bows. Coming out of the channel stay to the left. And that whole side of the lake is best. DBS and Top Guns work fine.There are some humps to the right as you head out of the channel.
