Glens Falls Project - LIHI Certificate #162, Hudson River, New York

The Glens Falls Project (FERC No. 2385) is located at river mile 200.7 on the Hudson River in the towns of Moreau, Saratoga County, and Glens Falls, Warren County, NY.

The project was originally constructed in 1906.  Project works include a portion of seven, 7.5-foot tall by 57-foot long hydraulically operated steel crest gates anchored on a 5-foot high concrete base. The dam impounds a reservoir of 167 acres with a useable storage volume of 560 acre-feet. The watershed area at the project is 2,817 square miles.

Water is conveyed to the powerhouse and to a paper mill via a 550-foot long power canal.  The powerhouse contains five horizontal Francis turbine generators with a combined capacity of 12.7 MW. A separate small dam and powerhouse located on the south side of the river is part of the unaffiliated South Glens Falls Project (No. 5461). Generally, both FERC licensees have agreed to equally share inflow to the reservoir (50 percent split) when flows are less than 8,400 cfs.

The Glens Falls Project operates in a run-of-river mode with average annual generation of 56,150 MWh.  Impoundment fluctuations are limited to 6 inches. A minimum flow of 5 cfs is provided in the 600-foot long bypassed reach to maintain water quality by preventing water stagnation and provide sufficient flow to adequately protect the limited aquatic habitat in the bypassed reach.
