Overview:
The Lost Pond Conservation Area is located in the extreme northwest corner of Brookline. This 30-acre tract of natural, undeveloped land adjoins the Kennard Park and Conservation Areas in Newton and the State¹s thirty acre Lost Pond Reservation. Together, these properties contain over one hundred acres of open woodland, rocky outcrops, marsh, bog and stream. Anetwork of trails interconnects these conservation properties. Lost Pond, one of the few natural ponds remaining in Brookline, is a ³kettle hole² pond, formed around a mass of ice left by glacial activity about 17,000 years ago. Aquaking peat bog developed on its northern edge. The Lost Pond Reservation, owned by the Massachusetts Department of Conservation and Recreation, property lies adjacent to Lost Pond Conservation Area. The pond is located on the reservation property. The sanctuary is used for wetland protection, conservation of wildlife habitat, environmental education, and passive exploration, such as bird-watching and nature walks.

Park History:
In 1915, Frederick Kennard diverted the Lost Pond drainage to South Meadow Brook. In 1945 the Town acquired the land. It was used for the Town¹s incinerator and landfill site from 1952 to 1975. It has since been used as a transfer station. Subsequent leaching from the landfill site near the Pond caused deterioration of water quality. The Town transferred a section of the land to the Conservation Commission in 1982. Two citizens bought the reservation property and donated it to the state.
