Bow Lake is in Strafford, with a small portion of the lake within the boundaries of Northwood. Once known as Bow Pond, it was dammed in the 1800s for mill power, which increased its size. The mills have long gone, but 1,149 acres of beautiful Bow Lake remain.
The Bow Lake Dam:
At the southeast end of Bow Lake, the Bow Lake Dam marks the beginning of the Isinglass River. The dam is owned and maintained by the State of NH.
On each side of the dam is a public swimming area. Please be aware that there are no lifeguards on duty. Swim at your own risk. Children 12 and under must be supervised by an adult. Chech NH DES Healthy Swimming Mapper for updated Advisories and Warnings: NHDES
