l. Project Description: The project consists of a 504.5-foot-long, 12-foot-high concrete dam that includes: (1) a 130-foot-long, 76-foot-wide powerhouse that includes: (a) an intake structure with five stoplog gates and trashracks with 1-inch clear bar spacing; and (b) five 596-kilowatt (kW) horizontal Kaplan turbine-generator units (Units 1 to 5), for a total installed capacity of 2,980 kW; (2) a 38.5-foot-long non-overflow section with three 9-foot-long sluice gates; (3) a 330-foot-long ogee spillway with a crest elevation of 258.0 feet above the National Geodetic Vertical Datum of 1929 (NGVD 29); and (4) a 6-foot-long east abutment. The dam creates an impoundment that has a surface area of 290 acres at a normal maximum surface elevation of 258 feet NGVD 29.

Water from the impoundment flows to Units 1 through 4, and then to a 235-foot-long tailrace that empties into the Oswegatchie River immediately downstream of the dam. Water also flows from the impoundment to Unit 5, and then to a 75-foot-long tailrace that empties into the Oswegatchie River approximately 620 feet downstream of the dam.

Electricity generated at the powerhouse is transmitted to the electric grid via 150-foot-long, 4.16-kilovolt (kV) generator lead lines, a 4.16/13.2-kV step-up transformer, and a 75-foot-long, 13.2-kV transmission line.

Project recreation facilities include a trailer boat access site and parking area on the east shore of the impoundment approximately 750-feet-upstream of the dam and a park on the east bank of the tailrace approximately 135-feet-downstream of the dam.

Ampersand proposes to continue operating the project in a run-of-river mode, and discharge up to 730 cfs through Unit 5, when Unit 5 is operating; or discharge 730 cfs or inflow, whichever is less, over the spillway when Unit 5 is not operating.
