June 26, 2020: The Low Impact Hydropower Institute has received a complete application for Low Impact Certification of the Stewart’s Bridge Hydroelectric Project. LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook. Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s application materials below.
Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered. Comments may be submitted to the Institute by e-mail at firstname.lastname@example.org with “Stewart’s Bridge Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Avenue, Suite 6, Lexington, MA 02420. Comments must be received on or before 5 pm Eastern time on August 25, 2020 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond.

The Stewart’s Bridge Project (FERC 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 dam with a concrete gated spillway. 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 Dam. Water is conveyed through a 216‐foot‐long steel penstock to the main powerhouse. 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 Francis turbine 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 base flow 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.
