The Glendale Project is located on the Housatonic River in the town of Stockbridge, Berkshire County, Massachusetts. The dam and powerhouse were built in 1906. The Housatonic River has a total drainage area of 1,948 square miles, flowing from its headwaters near the City of Pittsfield, southward for approximately 150 miles through western Massachusetts and Connecticut before emptying into Long Island Sound between Stratford and Milford Connecticut. The project is the seventh dam on the river upstream from its mouth at Long Island Sound.
The project includes a 250-foot-long, 30-foot-high concrete gravity dam with a 182-foot-long spillway and a gatehouse containing two manually-operated 10 by 10-foot canal intake gates and a waste gate slot equipped with two 8 by 8-foot waste gates. A new vertical Francis turbine generating unit is located in the gatehouse and has an installed capacity of 0.165 MW. It is used to generate power from passing the project’s required minimum flow. The intake is equipped with trashracks with 1-inch clear spacing. A 1,500-foot-long, 40-foot-wide intake canal conveys water to a forebay structure equipped with trashracks having 1-inch clear bar spacing, and one hydraulically-operated canal waste gate. A 250-foot-long, 12-foot-diameter steel penstock conveys water from the canal to the main powerhouse containing four vertical semi-Kaplan (fixed blade) turbine generating units having a total installed capacity of 1.14 MW. The tailrace channel is 300-feet long and the canal creates a 2,500 foot long bypass reach between the dam and the tailrace.
The project operates in run-of-river mode and impounds a 23-acre reservoir. The project has a minimum flow requirement of 90 cfs (or inflow if less) directed into the bypass reach for the protection and enhancement of fish and aquatic life habitat. The flow regime was developed in consultation with FERC and the Massachusetts Department of Environmental Protection. The project utilizes a Programmable Logic Controller to ensure run-of-river operations.
Waters within the project reach are designated Class B and impaired due to zebra mussel presence, excess algal growth, polychlorinated biphenyls (PCB) in fish tissue and sediment, and total phosphorus. A superfund site in Pittsfield, MA is responsible for the PCB impairment. The project’s Invasive Species Monitoring and Control Plan requires bi-annual reporting on presence of invasive species and control and removal efforts. The report is submitted to Massachusetts Department of Environmental Protection, Massachusetts Division of Fisheries and Wildlife, and US Fish and Wildlife Service. Run-of-river operation and continuous minimum flow have effectively eliminated any project impact on water quality.
Downstream dams create a barrier to upstream passage. No migratory fish species have been identified in the project area. Trashracks with 1-inch clear spacing and an approach velocity of no more that 2 feet per second mitigate entrainment.
The project property consists of roughly 12 acres. There are no lands of significant ecological value in the project area. The shoreline varies from low wetland area to steep, sloped banks. Residential development, roads, and railroad confine the vegetated riparian area. An Invasive Species Control Plan is required to control and monitor invasive plant species and high densities of zebra mussels in the project area.
Threatened and endangered species potentially present in the project vicinity include: Northern long-eared bat, dwarf scouring-rush, longnose sucker, skillet clubtail, and the creeper mussel.
The project does not have any plans for tree cutting or activities impacting habitat for Northern long-eared bat populations. Any vegetation management in the impoundment or bypass reach may require a rare plant protection plan preceded by a rare plant survey. Consultation with the Massachusetts Division of Fisheries and Wildlife’s Natural Heritage and Endangered Species Program provided four conditions that must be met in order to avoid prohibited take of state-listed species including provisions for non-emergency drawdown and refill, vegetation management, and wetlands protection.
The Glendale Project property, including 11 current and former structures, is listed on the National Register of Historic Properties. The project owner must consult with the State Historic Preservation Office, FERC, and Town of Stockbridge Historic Preservation Commission before undergoing any ground disturbing activities.
Recreational resources at the project include a canoe portage and fishing access. A river paddling guide is available and the downstream reach is designated Class III rapids. Public access is provided free of charge.
