Located in the Town of Wakefield, NH, within Carroll County, Pine River Pond is a 570 acre pond sitting at the headwaters of Pine River, which flows northwest into Ossipee Lake. PRP is about 3.6 miles in length and .6 miles in width with about 10.1 miles of shoreline, and is about 55 feet at its deepest spot. It is classified as mesotrophic (has neither an overabundance or a lack of plants), and its water level is controlled by the Arthur Fox Dam originally built in the 1920s and rebuilt to its current structure in 1977. The dam is owned and maintained by the State of NH, and the yearly drawdown is approximately 8 feet to Pine River Ponds natural high water mark.

Pine River Pond is part of the Saco Watershed whose headwaters flow from the White Mountains of NH to the Biddeford/Saco, ME area, and empty into the Saco Bay and the Atlantic Ocean. Threats to the watershed include development, visitors who potentially pollute the water, disrupt habitats, cause damage to shorelines and riverbanks, and introduce invasive species that threaten native plants and animals throughout the watershed.
