The Karner Brook Watershed ACEC is approximately 7000 acres in size and is located in the towns of Egremont and Mount Washington in southern Berkshire County. The ACEC is bordered by New York State to the west and the Schenob Brook Drainage Basin ACEC to the southeast.

The wildlife habitat resources of the ACEC are exceptional. This area contains over twenty state-listed rare species, three varieties of significant natural communities, including calcareous wetlands and acidic rocky summits, and critical fisheries habitat. The Karner Brook Watershed shares many of the same geological characteristics and habitat values as the adjacent Schenob Brook ACEC. In addition, Karner Brook is classified as a Class A, Outstanding Resource Water; Karner Brook is the sole source of high-quality drinking water for the South Egremont Water Company, which supplies water to residents and businesses in Egremont and Great Barrington.

The Karner Brook Watershed ACEC contains some of the most scenic landscapes in the Commonwealth. It includes a rich diversity of wooded mountains, rolling hills, open fields, and streams, ponds, and wetlands. Hiking and scenic vistas are available from the South Taconic Trail and the Appalachian National Scenic Trail, both of which traverse the ACEC. Agricultural lands and historic and archaeological resources complement the natural beauty and resource qualities of the area.
