項目描述：

The Stewart’s Bridge Project (聯邦能源監管委員會 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 壩 with a concrete gated 溢洪道. 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 壩. Water is conveyed through a 216‐foot‐long steel 壓力水管 to the main 發電站. 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 混流式水輪機 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 基流 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 peaking facility in tandem with E.J. West.
