Lake Winnipesaukee

About Lake Winnipesaukee

Lake Winnipesaukee is the largest lake in New Hampshire. It is approximately 21 miles (34 km) long (northwest-southeast) and from one to nine miles (1.6 to 15 km) wide (northeast-southwest), covering 69 square miles (180 km²) (71 square miles when Paugus Bay is included), with a maximum depth of 212 feet (64.6 meters).

The lake contains at least 253 islands, half of which are less than a quarter-acre in size (list of islands) and is indented by several peninsulas, yielding a total shoreline of some 288 miles. The driving distance around the lake is 63 miles. It is 504 feet (153 m) above sea level. Winnipesaukee is the third-largest lake in New England after Lake Champlain and Moosehead Lake.

Outflow is regulated by the Lakeport Dam (in Lakeport, New Hampshire) on the Winnipesaukee River.
