The Emeryville Project is located on the Oswegatchie River, in the Town of Fowler, New York. The 132 mile-long Oswegatchie river, a tributary to the St. Lawrence River, features many dams and hydroelectric facilities from its cabeceras in the northwestern Adirondacks to its confluence with the St. Lawrence – the Emeryville project is the ninth upstream presa located approximately two miles downstream of the Hollow Presa (FERC #6972) and two miles upstream of the Fowler #7 Dam (FERC #6059). The Oswegatchie multi-development project (LIHI #161) y el Newton Falls Project (LIHI #32) are both located upstream of the project and the Hailesboro No. 6 (LIHI #199), Hailesboro No. 4 (LIHI #198) y Hailesboro No. 3 (LIHI #197) projects are located downstream of the Fowler #7 Dam.
The history of the site dates back to the 1800s, when the waterpower was originally used to drive pulp grinders. In 1938, Rushmore Paper Mills, Inc. demolished the pulp mill and replaced it with a hydroelectric plant. Hampshire Paper Company (HPC) purchased the site from Rushmore Paper Mills in 1953. In 1987, HPC undertook a major renovation program by removing and replacing the central eléctrica, turbine-generator equipment, switchyard, and portions of the intake. The project is currently owned by KE Emeryville, LLC.
The Project includes the dam, compuerta, intake structure, bypass reach, and powerhouse containing one turbine. The dam is an existing 16.7-foot-high, 185-foot-long, concrete-capped timber and earth fill presa de gravedad with a 176-foot-long concrete aliviadero equipped with 2.4-foot-high tableros de flash and a 4-foot-wide, 0.5-foot-deep minimum flow weir. The intake structure consists of a 140-foot-long by 30-foot-wide reinforced concrete headgate canal artificial, equipped with four compuertas de entrada and trashracks with 5-inch clear bar spacing. The 60-foot-long, 14-foot-diameter penstock leads to the concrete powerhouse containing the horizontal axial flow turbine with an installed capacity of 3.481 MW. Flows are released to the tailrace and power generated is sent to the grid via the 80-foot-long, 23-kilovolt transmission line. The bypassed reach is 229 feet long and runs under Route 22, between Emeryville dam and downstream of the powerhouse.
El proyecto opera en de pasada mode and impounds a 35-acre reservoir. The project provides minimum flows of 20 cfs into the bypassed reach year-round. A headpond sensor monitors impoundment elevation and automatically adjusts turbine discharge to maintain impoundment elevation. The flow regime was developed in consultation with New York Department of Environmental Conservation (NYSDEC) and USFWS. This regime is intended to protect aquatic species and enhance habitat.
Waters within the project reach are designated as Class A. Designated uses, as prescribed by NYSDEC, include supply for drinking, culinary or food processing purposes, primary and recreación de contacto secundario, and fishing. Water quality testing found that bioindicators including dissolved oxygen and pH levels were unchanged upstream and downstream of the project.
Migratory fish species are not present in the Oswegatchie River at the project and upstream passage is also blocked by downstream dams. A bypass flume provides passage for resident fish into a piscina de inmersión in the bypassed reach. Trashracks with 1-inch spacing are installed seasonally (March 15 – November 30) which exclude fish passing through the turbines. The project owner improved this paso de peces by deepening and expanding the plunge pool as well as removing rocks that had the potential to damage riverine species in the bypass chute.
The project property consists of roughly 55 acres not including the impoundment. An invasive species monitoring plan has been implemented at the project to eradicate pale swallow wort populations. The project has installed informational signage, public disposal stations, and has trained staff in identification of the species as well as proper removal and disposal procedures.
Threatened and endangered species potentially within project vicinity include: Northern Long-eared bat, Indiana Bat, Lake Sturgeon, Mooneye, Eastern Sand Darter, Fernald’s Sedge. No critical habitats for either of the bat species exist in the project area. The sedge species is not impacted by project operations and the fish species have been known to occur downstream of the project but not in the project vicinity. No spawning habitat has been observed in the project area regardless of the presence of suitable habitat.
The State Historic Preservation Office and U.S. Army Corps of Engineers have noted that project operations have no impact on any registered historic properties.
Recreational resources at the project include two boat ramps that provide access to the impoundment and tailrace, a canoe portage trail, and a picnic area.
