n. Project Description: The project as currently licensed consists of the following three developments from upstream to downstream: the 1.05-megawatt (MW) Kosterville Development, the 2-MW Gouldtown Development, and the 11.2-MW Lyons Falls Development.

Project Facilities

Kosterville Development

The Kosterville Development consists of a concrete dam (Kosterville Dam) that includes: (1) a non-overflow section; (2) a 314-foot-long spillway with a crest elevation of 889.5 feet mean sea level (msl); (3) a non-overflow gated section with three 11-foot-long stoplog gates; and (4) an intake structure with three steel sluice gates and a trashrack with 2-inch clear bar spacing.

The dam creates an impoundment that has a surface area of 3 acres at the spillway crest elevation of 889.5 feet msl. From the impoundment, water flows through the intake structure to a bay that includes two horizontal Francis turbines. The turbines are connected to a 0.55-MW generator and a 0.50-MW generator that are located in a 50-foot-wide, 50-foot-long steel and concrete powerhouse adjacent to the turbine bay. Water is discharged from the turbines to the Moose River.

The minimum and maximum hydraulic capacities of the turbines are 150 and 540 cubic feet per second (cfs), respectively. The Kosterville Development's generators are connected to the regional electric grid by an approximately 0.25-mile-long, 2.3-kilovolt (kV) overhead generator lead line and a 2.2/24-kV step-up transformer.

The Kosterville Development's project recreation facilities include a portage route on the north side of the impoundment that includes a take-out approximately 80 feet upstream of Kosterville Dam and a put-in approximately 100 feet downstream of the dam.

Gouldtown Development

The Gouldtown Development consists of a concrete dam (Gouldtown Dam) that includes: (1) a 30-foot-long intake structure with a 10-foot-long, 10-foot-high gate and a 30-foot-long, 12-foot-high trashrack with 2-inch clear bar spacing; (2) a south dam section that includes: (a) a low-level outlet gate and a sluice gate; (b) an 84-foot-long gated section with eleven 5-foot-high steel gates; and (c) a 50.7-foot-long abutment; and (3) a north dam section that includes: (a) a non-overflow section with a low-level outlet gate and a sluice gate; (b) a 100-foot-long spillway with 3-foot-high flashboards that have a crest elevation of 855 feet msl; and (c) an abutment section. The dam abuts a 4-acre island in the Moose River, between the south and north sections of the dam.

The dam creates an impoundment that has a surface area of 10 acres at the flashboard crest elevation of 855 feet msl. From the impoundment, water flows through the intake structure to a 105-foot-long, 10-foot-diameter steel penstock that conveys water to a bay that includes a horizontal Francis turbine and a surge pipe. The turbine is connected to a 2-MW generator that is located in a 48-foot-wide, 38-foot-long concrete powerhouse adjacent to the turbine bay. Water is discharged from the turbine to the Moose River.

The Gouldtown Development creates the following bypassed reach segments: (1) an approximately 200-foot-long segment downstream of the south section of the dam; and (2) an approximately 1,000-foot-long segment downstream of the north section of the dam that discharges approximately 230 feet downstream of the powerhouse (north channel bypassed reach). Northbrook releases minimum flows to the north channel bypassed reach through a 1.25-foot-diameter pipe that is attached to the sluice gate of the north dam.

The minimum and maximum hydraulic capacities of the turbines are 160 and 726 cfs, respectively.

The Gouldtown Development's generator is connected to the regional electric grid by: (1) 2.3-kV generator lead lines; (2) a step-up transformer located in a substation; and (3) an approximately 1-mile-long, 23-kV overhead transmission line.

The Gouldtown Development's project recreation facilities include: (1) a portage route on the north side of the impoundment that includes a take-out approximately 200 feet upstream of Gouldtown Dam and a put-in approximately 800 feet downstream of the dam; and (2) a parking area adjacent to the intersection of Kosterville and Shibley Roads.

Lyons Falls Development

The Lyons Falls Development currently consists of a concrete dam (Lyons Falls Dam) that includes: (1) a west abutment; (2) an intake structure with three sluice gates equipped with an 89-foot-long trashrack with 2-inch clear bar spacing; (3) an approximately 73.3-foot-long non-overflow section with a low level outlet gate, a 3.8-foot-long, 6-foot-high sluice gate, and two 25-foot-long, 6-foot-high steel sluice gates; and (4) a 362-foot-long spillway with 2.2-foot-high flashboards that have a crest elevation of 806.5 feet msl.

The dam creates an impoundment that has a surface area of 130 acres at the flashboard crest elevation of 806.5 feet msl. From the impoundment, water currently flows through the west sluice gate of the intake structure to a 250-foot-long, 6-foot-diameter penstock and a 250-foot-long, 12-foot-diameter penstock, and through the east sluice gate of the intake structure to a 125-foot-long, 8-foot-diameter penstock. The two 250-foot-long penstocks currently convey water to two 1.2-MW horizontal turbine-generator units, a 1.25 MW horizontal turbine-generator unit, and a 0.9 MW horizontal turbine-generator unit located in a 47-foot-long, 110-foot-wide brick and concrete powerhouse for a total installed capacity of 4.55 MW. The 125-foot-long penstock currently conveys water to a 1.04-MW vertical turbine-generator unit located in a 30-foot-long, 30-foot-wide powerhouse.

Water is currently discharged from the turbines to the Black River. The Lyons Falls Development creates an approximately 300-foot-long bypassed reach.

The minimum and maximum hydraulic capacities of the turbines are currently 410 and 1,170 cfs, respectively.

The Lyons Falls Development's generators are currently connected to the regional electric grid by: (1) 2.3-kV generator lead lines; (2) two 2.3/23-kV step-up transformers; (3) two 23-kV overhead transmission lines; and (4) a 540-foot-long, 23-kV overhead transmission line.

The Commission approved a license amendment on March 30, 2016 (2016 Order), to increase the installed capacity of the Lyons Falls Development from 5.61 MW to 11.2 MW by replacing the powerhouses and intake facilities with new facilities, including two new 5.6-MW turbine-generators. Northbrook has not commenced construction of the new facilities. Commission staff issued a letter on May 8, 2024, granting Northbrook's request for an extension of time to start and complete construction by September 30, 2025 and September 30, 2027, respectively. In the license application, Northbrook states that it is still proposing to construct the new intake and powerhouse facilities.

The Lyons Falls Development's project recreation facilities include a portage route around the east side of the dam and a boat access site, picnic area, and parking area downstream of the dam.

Project Operation

The current license requires the licensee to operate the project in a run-of-river mode. Northbrook maintains the surface elevation of the Lyons Falls, Gouldtown, and Kosterville Developments' impoundments at 806.5 feet, 855 feet, and 889.5 feet msl, respectively. The current license requires the licensee to release a minimum flow of 5 cfs or inflow, whichever is less, from the Gouldtown Development to the north channel bypassed reach. The current license also requires the implementation of a recreation plan filed on July 20, 1987, and revised on July 28, 1988.

The average annual energy production of the project ( i.e., Lyons Falls, Gouldtown, and Kosterville Developments) from 2019 through 2023, was 33,601 megawatt-hours.

The 2016 Order amended the license to include several additional conditions for the construction of the new intake and powerhouse facilities, including but not limited to: (1) preconstruction requirements, such as a stream flow and water level monitoring plan and invasive species management plan; and (2) conditions required by the New York Department of Environmental Conservation's water quality certification, such as: (a) restrictions on the timing of construction, impoundment drawdowns/dewatering activities, dredging, sediment disposal, placement of cofferdams, and erosion control measures during construction; and (b) run-of-river operation, water level fluctuation limits, minimum bypassed reach flows, seasonal installation of 1-inch trashrack overlays, a trashrack management plan, and downstream fish passage measures following construction.

Northbrook proposes to revise the project boundary around the impoundments to follow the normal maximum impoundment elevations and add/remove land that is occupied by or adjacent to project facilities, which would result in a net reduction of land and water in the project boundary from 202 acres under the current license to 196 acres under the proposed relicensing.

Northbrook proposes to continue operating the project in a run-of-river mode. Northbrook proposes to maintain the surface elevations of the impoundments within 6 inches of the flashboard crests or the spillway crests if flashboards are not in place. Northbrook also proposes to: (1) release a continuous minimum flow of 10 cfs or inflow, whichever is less, to the north channel bypassed reach of the Gouldtown Development; (2) install trashrack overlays with 1-inch clear bar spacing at each development from April 15 through October 15; (3) implement a stream flow and water level monitoring plan as required by the 2016 Order; (4) implement the Invasive Species Management Plan, Bat Management Plan, and Bald Eagle Management Plan filed as Appendices H, I, and J of Volume 1 of the license application, respectively; (5) release an aesthetic flow of 0.5 inch of spill over the dam/flashboard crest of each development from Memorial Day to Labor Day; (6) revise the Recreation Plan required under the current license; (7) construct a parking lot for up to 15 cars at the Kosterville Development; (8) develop a walking trail to the pool below the Gouldtown Development waterfall; (9) provide public access to the Kosterville Development from 8:00 a.m. to 7:00 p.m. on whitewater release days; (10) cease generation at the Kosterville and Gouldtown Developments and release all inflow from the spillways when the Moose River Project is releasing whitewater boating flows; and (11) install directional and safety signage at project recreation facilities.
