k. Project Description: The existing Kelley's Falls Project consists of: (1) An approximately 230-foot-long, 31-foot-high concrete and stone masonry dam that includes: (a) An approximately 31-foot-long stone masonry east abutment with an intake structure that includes an 11-foot-wide, 11-foot-high headgate equipped with a 22.2-foot-wide, 17-foot-high trashrack with 2.5-inch clear bar spacing; (b) a 192-foot-long concrete ogee spillway section with: (i) A 6-foot-wide, 2.75-foot-high steel slide gate that includes a 3-foot-wide, 2-foot-high notch; (ii) 2.75-foot-high flashboards; and (iii) a crest elevation of 160.75 feet mean sea level (msl) at the top of the flashboards; and (c) a 7-foot-long concrete west abutment with a 3.5-foot-diameter gated, low-level outlet pipe; (2) a 284-foot-long, 2.5-foot-wide stone retaining wall on the east river bank that connects to the east abutment of the dam; (3) an impoundment (Namaske Lake) with a surface area of 154 acres at an elevation of 160.75 feet msl; (4) a 65-foot-long underground steel and concrete penstock; (5) a 28-foot-long, 28-foot-wide brick masonry and steel powerhouse containing a 450-kilowatt vertical Francis turbine-generator unit; (6) a 275-foot-long, 2.4-kilovolt (kV) underground transmission line that connects the generator to a 2.4/12-kV step-up transformer; and (7) appurtenant facilities. The project creates an approximately 65-foot-long bypassed reach of the Piscataquog River.

GMP voluntarily operates the project in a run-of-river mode using an automatic pond level control system, such that project outflow approximates inflow. GMP maintains the impoundment at the flashboard crest elevation of 160.75 feet msl.

Article 25 of the current license requires GMP to release a continuous minimum flow of 45 cubic feet per second (cfs) or inflow to the impoundment, whichever is less, as measured immediately downstream of the powerhouse. Downstream fish passage is provided for river herring through the notch in the slide gate located on top of the spillway. There are no upstream fish passage facilities at the project.

The minimum and maximum hydraulic capacities of the powerhouse are 175 and 420 cfs, respectively. The average annual generation of the project was approximately 1,572 megawatt-hours from 2014 through 2020.

GMP is not proposing any changes to project facilities or operation.
