l. *Project Description:* The Weston Dam Project includes a 220-foot-long, 15.5-foot-high concrete-covered stone and timber crib dam (Weston Dam) that consists of the following sections: (a) a 120-foot-long concrete cap spillway topped with 4.5-foot-high wooden flashboards with a crest elevation of 867.7 feet National Geodetic Vertical Datum of 1929 (NGVD 29) at the top of the flashboards; (b) a 60-foot-long right abutment section on the northwest side of the spillway with two slide gates; and (c) a 40-foot-long left abutment section on the southeast side of the spillway with a 20-foot-long, 15-foot-wide gatehouse and two slide gates.
The dam creates an impoundment with a surface area of 30 acres and a storage capacity of 115 acre-feet at an elevation of 867.7 feet NGVD 29. On the right abutment, there is a 10.83-foot-wide, 20-foot-high intake structure that includes a trashrack with 2-inch clear bar spacing. Water flows directly from the intake to a 36.5-foot-long, 36-foot-wide powerhouse that contains two Kaplan turbine-generator units. Water is discharged back into the Upper Ammonoosuc River directly from the turbines. There is no bypassed reach at the project.
Electricity generated at the project is transmitted to the electrical grid via two 0.48 kilovolt (kV) generator leads; three 0.48/34.5-kV transformers; and a 34.5-kV, 300-foot-long transmission line. The minimum and maximum hydraulic capacities of the turbine-generator units are 50 and 550 cubic feet per second (cfs), respectively. The average annual energy production of the project from 2013 through 2022 was 2,357 megawatt-hours.
The current license requires Powerhouse to operate the project in an instantaneous run-of-river mode to protect fish and wildlife resources, such that project outflow approximates inflow. Powerhouse maintains the impoundment at the flashboard crest elevation of 867.7 feet NGVD 29.
Under a subsequent license, Powerhouse proposes to continue the project as a run-of-river facility and does not propose any new PM&E measures.
