The Piercefield Project is located on the Raquette River near the Town of Piercefield in Franklin and St. Lawrence Counties in New York. The project barrage et centrale were originally constructed in 1899 by the International Paper Company to provide mechanical power to the paper making process. The facility was converted to an electric generating station in 1926. Several other modifications took place in the early 1900s and later in the 1970s to replace timber sections of the structures with stronger concrete structures.
The Raquette River has a total drainage basin of 1,269 square miles at its mouth and originates in the Adirondack highlands at Blue Mountain Lake, Raquette Lake and Long Lake. The river flows generally north-northwest for more than 146 miles, through Potsdam, New York, and empties into the St. Lawrence River, near Massena, New York.
A total of 19 hydroelectric projects exist on the Raquette River, most of which are owned by the project owner including from upstream to downstream, Yaleville (LIHI #157), Raquette supérieure (LIHI #14A), Middle Raquette (LIHI #14B), et Lower Raquette (LIHI #14C). The project itself is the southernmost and furthest upstream dam on the river.
The project includes: the dam, retaining wall, stop-log déversoir, ogive spillway, bypassed reach, powerhouse, one vertical Turbine Francis, and two horizontal double Turbines Francis./p>
The dam is a 23-foot-high concrete and timber dam, approximately 300 feet long with a 495-foot-long retaining wall/dike on the right shoreline. A 700-foot-long retaining wall is located along the left shoreline. The déversoirs include a 118-foot-long stanchion type journal d'arrêt spillway and a 294-foot-long, 23-foot-high ogee spillway section with an Obermeyer inflatable 2-foot-high tableau flash system, and a 110-foot-long forebay retaining wall. A 550-foot-long bypassed reach is created by the dam. The powerhouse contains one vertical Francis unit and two horizontal double Francis units with a combined capacity of 2.7 MW.
Le projet fonctionne dans un environnement modifié au fil de l'eau mode and impounds a 370-acre reservoir that extends 1.9 miles upstream. The project provides a minimum flow of 150 cfs in the tailrace and impoundment fluctuations are maintained within 1-foot from the top of the tableaux d'affichage. This flow regime was developed in collaboration with the New York State Department of Environmental Conservation (NYSDEC), US Fish and Wildlife Service (USFWS), the Adirondack Park Agency, and New York Rivers United. The parties involved concur that this flow regime provides adequate habitat downstream and maintains a stable vegetative buffer around the reservoir. An additional 20 cfs is provided farther down in the bypassed reach to provide attraction flows away from intakes to minimize fish entraînement and to provide downstream passage.
Waters within the project reach are designated as Class C. There are no impaired waters in the project vicinity and NYSDEC has confirmed that the project continues to meet every designated use group.
Downstream waterfalls and water features create natural barriers to passage for migratory fish species at the project. The project reach supports resident fish populations of yellow perch, walleye, rock bass, smallmouth bass, lake whitefish, fallfish, and golden shiner. Walleye are particularly abundant in the project area. The 150-cfs minimum flow requirement supports fishery resources downstream of the project and the 20-cfs downstream fish bypass provides adequate passage and trashracks with 1-inch spacing mitigate potential for entrainment. This design was approved by NYSDEC and USFWS for downstream passage protection.
The project lands consist of roughly 18 acres located in the Adirondack State Park, and is governed by Part 577 of the Wild, Scenic, and Recreational Rivers Act which restricts new structure development, promotes forest management, and requires a buffer zone from the river’s edges. The project operates under a flow and water level monitoring plan which minimizes effects to the shoreline via limiting impoundment fluctuations. This ensures an adequate vegetative buffer on the shoreline and minimizes erosion.
Threatened or endangered species potentially present in the project vicinity include the Northern long-eared bat, bald eagle and spruce grouse. The project is in compliance with USFWS Rule 4(d) concerning the protection of Northern long-eared bat populations as well as the NYSDEC Conservation Plan for bald eagles. These provisions primarily dictate avoidance of tree clearing operations during specific nesting periods. NYSDEC also determined that the project does not have any impact on spruce grouse populations. Via consultation with NYSDEC in 2019, it was concluded that bald eagle populations are doing very well in New York and project operations do not pose any threat to their success.
Historic properties in the project area include the Piercefield dam and powerhouse, built in 1899 by the International Paper Company to produce newsprint. The project owner developed a historic properties management plan in consultation with the State Historic Preservation Office (SHPO) in order to identify historic properties, provide protective maintenance, and facilitate improvements. The project owner trained its operation staff to provide weekly monitoring updates on the historic properties and files annual reports with the SHPO.
Recreational resources at the project include a boat launch, canoe put-in/take-out areas, and two designated bank fishing areas. The project owner provides a 750-cfs recreational release for five hours on the last Saturday in June. Public access is provided free of charge.
