What lake aka Twin Lakes is the fifth largest lake entirely in New Hampshire?
Little Sunapee Lake Little Sunapee Lake (or "Little Lake Sunapee", a frequent local usage) is a 486 acre water body located primarily in Merrimack County in central New Hampshire, United States, in the town of New London. A small portion of the lake crosses into neighboring Springfield in Sullivan County. The lake is sometimes referred to as "Twin Lakes" due to a long, narrow peninsula which nearly cuts the lake in half. Water flowing out of the lake passes through Goose Pond and Otter Pond before entering Lake Sunapee. Bucklin Beach is a Town of New London recreation area at the east end of the lake.
Harrisville Pond Harrisville Pond is a 138 acre water body located in Cheshire County in southwestern New Hampshire, United States, in the town of Harrisville. It is one of many lakes and ponds along Nubanusit Brook, a tributary of the Contoocook River. Water from Nubanusit Lake flows via the Great Meadows into the pond on the north side and out of the pond at two dams on the south side. One dam allows the level of the pond to be raised or lowered and also adjusts the flow through the mills that span that part of the outlet, while the other dam is made of large stones and sandbags. The village of Harrisville is located at the outlet of the pond.
