North Hill Marsh Pond is a 38-acre (150,000 m²) pond in Duxbury, Massachusetts, USA. The pond is the headwaters to the Back River. The pond is located northeast of Round Pond and north of Island Creek Pond. A wildlife sanctuary borders this pond to the south, and the North Hill Country Club, accessible via Merry Avenue, off Route 14, borders this pond to the northeast. The water quality is impaired due to non-native aquatic plants in the pond.^[1]
