Lake Winnipesaukee is the largest lake in the American state of New Hampshire and the third-largest lake in New England after Lake Champlain and Moosehead Lake. It is approximately 21 miles (34 km) long (northwest-southeast) and from 1 to 9 miles (1.6 to 14 km) wide (northeast-southwest). The lake contains at least 253 islands, half of which are less than a quarter-acre in size, and is indented by several peninsulas, yielding a total shoreline of approximately 288 miles (463 km).
