Descripción del proyecto:

The Stewart’s Bridge Project (Comisión Federal de Comercio No. 2047) is located at river mile 3 on the Sacandaga River in the town of Hadley, Saratoga County, New York. The Sacandaga River is a tributary to the Hudson River.   Great Sacandaga Lake (FERC No. 12252) controls 1,044 square miles of the drainage area that contributes to the hydroelectric projects on the Hudson River. Discharges from the reservoir are regulated by the Hudson River Black River Regulating District.

The project works include a 1,646-foot long by 112-foot high earthen presa with a concrete gated aliviadero. The dam was constructed in 1951. The dam impounds a 480-acre reservoir which extend about 3 miles upstream to the tailwaters of the E.J. West project at the Conklingville Presa. Water is conveyed through a 216‐foot‐long steel compuerta to the main central eléctrica. A 275‐foot‐long penstock connected to the main penstock conveys water to the minimum flow powerhouse which was constructed in 2013. The main powerhouse contains one vertical Turbina Francis with a capacity of 30 MW and the minimum flow powerhouse contains one axial flow unit with a capacity of 2.55 MW.   The FERC project boundary covers 700 acres (210 acres of land and 490 acres of water).

The project operates with a 1.0‐foot impoundment fluctuation limit. A flujo base between 300 and 350 cfs is required year round based on the reservoir elevation. The project generates approximately 126,105 MWh annually and operates as a alcanzando su punto máximo facility in tandem with E.J. West.
