Hinsdale Flats Watershed ACEC Designation
Total Approximate Acreage: 14,500 acresWatershed(s): Housatonic and WestfieldMunicipalities: Dalton, Hinsdale, Peru, and Washington
The Hinsdale Flats Watershed ACEC covers approximately 14,500 acres and is located at the headwaters of the East Branch of the Housatonic River in four communities in central Berkshire County. The ACEC is generally defined by several watershed subbasins that contribute to the northward-flowing headwaters of the East Branch of the Housatonic above the Old Grist Mill Dam in the town of Hinsdale.
Beginning in the town of Washington, the East Branch flows through extensive wetlands and floodplains known as the Hinsdale Flats. Tributary streams flow into the Flats and East Branch from higher elevations and ridges to the east, west, and south. The Appalachian National Scenic Trail forms the western boundary of the ACEC. The unique topography and contrasting land forms provide scenic vistas of the lowlands of the Flats and the predominantly wooded uplands that surround it. Open fields and farmlands, extensive forestlands, and historic and archaeological resources are integral parts of the ACEC.
The excellent water quality of the East Branch and its tributaries, the wetlands and floodplains of the Hinsdale Flats, and the surrounding uplands support an outstanding variety of natural communities and wildlife, including six state-listed rare species. Several summer camps, vacation homes, and public recreation areas (including the Hinsdale Flats Wildlife Management Area, Ashmere Lake, and Plunket Reservoir) benefit from the natural beauty and resources of the area. Surface and ground water provide drinking water for residents of the area, and the headwaters contribute to important water supplies downstream. The unique environmental qualities of the area are important to the entire Berkshire region.
