The Yaleville Project is located on the Raquette River near the Town of Yaleville in Franklin and St. Lawrence Counties in New York. The Project was originally constructed in 1903 for the sole purpose of power production. Several improvements were made to the project throughout the 1900s. This included a new concrete buse in 1919; a concrete barrage replaced the log dam and water wheels were replaced with the current hydropower equipment; a new centrale was constructed in 1922; the forebay was constructed and the turbine room floor was overlaid in 1977; the déversoir et canal walls were reconstructed in 1978; the tailrace journal d'arrêt structure and tailrace were repaired in 1982; and concrete repairs were made to the dewatering facilities. These upgrades culminated in 1987 with the installation of new tête portes and a head gate lifting frame at the project intake.
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, Piercefield (LIHI #156), Raquette supérieure (LIHI #14A), Middle Raquette (LIHI #14B), et Lower Raquette (LIHI #14C). The Yaleville Project sits between the Norwood and East Norfolk developments of the Lower Raquette River Project.
The project includes a dam, flood gate structure, bypassed reach, intake structure, forebay, powerhouse, and two generating units.
The dam is a concrete gravity overflow dam about 170 feet long and 13 feet high, with 1.5-foot-high tableaux d'affichage at the crest, a concrete gravity flood gate structure 75 feet long and composed of four stanchion bays, 15 feet long and 10 feet high. Each stanchion bay has a central I-beam support creating two 7.5 ft bays for a total of 8 bays. Each individual bay has 10 ft of horizontal timber stoplogs topped with a 5 ft high steel slide gate A bypassed reach, approximately 485 feet long, is created by the dam. Water is conveyed to the intake via a forebay (canal) that is 60 feet wide and 275 feet long. The intake structure is integral to the upstream side of the powerhouse. The powerhouse contains two vertical Francis units with a combined capacity of 0.725 MW.
The project is operated in a au fil de l'eau mode and impounds a 95-acre reservoir that extends approximately 1.8 miles upstream. Passe à poissons flows are maintained at 36 cfs after spring runoff and flashboards are reinstalled (around May 15 annually) until November 1. Mise en fourrière fluctuations are monitored by the project owner and operational adjustments are made to ensure run-of-river compliance. This flow regime was developed via recommendations from US Fish and Wildlife Service (USFWS) to preserve suitable aquatic habitat for resident fish species. The New York State Department of Environmental Conservation (NYSDEC) manages the Raquette River as a mixed warm-water/cool-water fishery resource.
Waters in the project reach are designated as Class B, managed for high quality aquatic habitat and primary and loisirs de contact secondaire. The project reach is also listed as impaired for pathogens and exhibits low dissolved oxygen concentrations. The pathogen impairment is caused by poorly operated wastewater treatment plants in nearby municipalities. Low dissolved oxygen levels have been exhibited in the river since the 1940s but have been steadily improving. The project’s turbine hydraulic capacity frequently allows for spillway flows which help to aerate waters moving downstream.
NYSDEC manages the Raquette River as a mixed warm-water/cool-water fishery. The fish population is comprised of both game and pan fish including walleye, smallmouth bass, northern pike, yellow perch, rock bass, pumpkinseed, and brown bullhead. Historical records of poisson anadrome presence have not been found for the project vicinity. Migratory species within the project reach include American eel. An upstream échelle à anguilles operates between June 15 and September 15 as recommended by USFWS and NYSDEC. Additionally, a rectangular weir downstream passe à poissons is operated from May 15 (after spring runoff and tableau flash installation) through November 1. The fishway discharges 36 cfs into a 3-ft deep piscine de plongée. Trashracks with 1-inch spacing mitigate entraînement of resident species.
The project lands consist of roughly 14 acres. The surrounding lands are primarily rural, agricultural, and forested. The shoreline is predominantly shrub land and no lands of significant ecological value exist in the project area. The project’s run-of-river operations help to minimize impoundment fluctuation and thus reduce the potential for shoreline erosion.
Threatened or endangered species potentially present in the project vicinity include the Northern long-eared bat and bridle shiner. No critical habitats are located in the project area and the project operates under the USFWS 4(d) rule concerning Northern long-eared bat protection. This rule primarily concerns the cutting of trees, potential habitat for the bat species, from June 1 through July 31. The bridle shiner, a small minnow species, has been documented in the upstream vicinity of the project and is a state species of conservation concern.
No known historic or cultural resources exist in the project area. A metal truss bridge was constructed downstream of the project in 1892 which is potentially eligible for listing on the Registre national des lieux historiques. Consultation with the State Historic Preservation Office (SHPO) concluded that the project would have no effect on the resource and did not recommend any provisions for its protection, however, the bridge is not part of the project. Further consultation with the SHPO is required should the project plan any construction or ground-disturbing activities.
Recreational resources at the project include a canoe portage route with picnic area, parking, signage, and upstream and downstream put-ins/take-outs. Public access is provided free of charge where safe.
