Pawtuckaway Lake is a 783-acre (3.17 km2) water body located in Rockingham County in southeastern New Hampshire, United States, in the town of Nottingham. The official name of the lake is Pawtuckaway Pond. The original, natural pond was enlarged in the 19th century by the construction of four dams. Three of the dams, near the southern end of the lake, feed the Pawtuckaway River, which flows southeast to the Lamprey River in the western part of the town of Epping. The fourth dam, located at the north end of the lake, releases water to the Bean River, leading to the North River and ultimately the Lamprey River in the northern part of Epping. The lake is located in the Piscataqua River drainage basin.
