20 foot boat slip at Newfound Lake Boat Club. No waiting to launch your boat because your boat is sitting here waiting for you. Just jump in your car, come to the lake and get in the boat, relax, unwind on what some say is one of the cleanest lake in NH. 4,106 acres in size and is considered one of the deepest lakes in NH (168-feet deep at one point, and at another, 183 feet deep.) This pristine lake is about two and a half miles wide and seven miles in length. What a great place to have a boat slip. Newfound Lake Boat Club is a gated and private community with changing areas, bathrooms, an area for club meetings, tables, shared electricity at the dock with your neighbor and a launch. Annual fee of $300 includes use of facilities and winter storage. So come to the lake, relax, unwind and put this on replay for the whole summer. A short cruise down the Fowler River brings you to Newfound Lake.
