LIHI Certificate #13 - Hoosic River Project, New York
The Hoosic River Project consists of two developments on the Hoosic River east of its confluence with the Hudson River: the Johnsonville Development and the Schaghticoke Development, located in Johnsonville and Schaghticoke, Rensselaer County, New York, respectively. The Valley Falls Dam is located between the developments. One dam lies upstream of the project, the Hoosick Falls Project, with no dams downstream of the Schaghticoke facility. The facilities were built between 1909 and 1910 for the purpose of supplying power to the local area.
The project was relicensed by FERC in 2002 after a collaborative effort to develop the Hoosic River Project Settlement Offer (HRPSO). The HRPSO provides for the continued operation of the project with appropriate long-term environmental protection and diverse objectives for maintain a balance of power and non-power values in the Hoosic River Basin. Those included in this effort are as follows: the project owner, the Adirondack Mountain Club (ADK), American Rivers (AR), American Whitewater (AW), New York Rivers United (NYRU), New York State Conservation Council (NYSCC), New York Department of Environmental Conservation (NYSDEC), Rensselaer County Conservation Alliance (RCCA), Town of Schaghticoke (TOS), Trout Unlimited (TU), US Fish & Wildlife Service (USFWS), US National Park Service (USNPS) and the Village of Schaghticoke (VOC).
The project includes two separate facilities, described below:
The Johnsonville Development consists of:
- a 39-foot-high, 529-foot-long concrete gravity dam topped with 2.5-foot-high wooden flashboards;
- a reservoir with a 450-acre surface area;
- a sluice gate;
- a forebay structure;
- an intake structure equipped with 1-inch clear-spaced vertical trashracks;
- a powerhouse immediately adjacent to the dam containing two turbine generators with a total installed capacity of 2.1 MW.

|Average Annual Generation||83,000 MWh|
|FERC No.||P-2616 issued 2002, expires 2042|
The Schaghticoke Development consists of:
- a 28-foot-high, 700-foot- long concrete gravity dam topped with 2.5-foot-high wooden flashboards and a pneumatic gate;
- a reservoir with a 150-acre surface area;
- a 2,300 foot-long open canal;
- a set of forebay intake gates;
- a forebay;
- a pipeline intake equipped with 1-inch clear-spaced vertical trashracks;
- an 820 foot-long, 12.5- foot-diameter steel pipeline. This pipeline directs water from the forebay downward to the bypassed reach. It passes over the bypassed reach by the means of a support bridge, then heads up the other side of the river overbank to a surge tank;
- a surge tank;
- five penstocks directing water from the surge tank to the powerhouse;
- a powerhouse containing four turbine generators with a combined capacity of 16.4 MW.
The canal, forebay, pipeline, and penstocks create a two-mile bypassed reach between the dam and the powerhouse.
The project operates in a peaking mode. Reservoir fluctuations are seasonal and site-specific. The Johnsonville development limits daily fluctuations to 0.25 feet from June 1-September 30 and 0.5 feet from October 1-May 31. Daily fluctuations are limited to 0.5 feet at the Schaghticoke development. The Schaghticoke facility provides a year-round minimum flow of 60 cfs into the bypass reach to maintain habitat for nearly all fish species and life stages. Additionally, the Schaghticoke facility provides a year-round base flow of 240 cfs downstream of its powerhouse and the Johnsonville facility provides a year-round base flow of 220 cfs downstream of its powerhouse. This enhances aquatic habitat in periods of low flow and addresses a historic issue of dewatering the downstream reaches due to hydropower operations on the river. This flow regime was developed as a part of the HRPSO with guidance from the contributing members.
Waters within the project reach are designated Class B in the Hoosic River and Class C in the Schaghticoke Reservoir. Class B waters are best used for aquatic biota and wildlife habitat as well as primary and secondary contact recreation. Class C waters have similar designated uses, but some factors may limit the designated uses. A fish consumption advisory is in effect in the project area due PCB contaminated sediments. This impairment has been noted by NYSDEC as a result of legacy pollutants from past industrial discharges into the river upstream of the project and thus not a result of project operations.
Historically, the falls at Schaghticoke limited upstream movements for most anadromous fish species in the river. However, USFWS indicated that there are sufficient ledges, cracks and flumes in the falls to likely allow American eel to ascend them. In general, the Hoosic River in the Project area supports both warm and coldwater fish species, but the fish community is dominated by warmwater species. Common species include shiner, spottail shiner, golden shiner, fallfish, carp, white sucker, rainbow and brown trout, northern pike, largemouth and smallmouth bass, rock bass, black crappie, pumpkinseed, bluegill, and yellow perch. Both project facilities operate eel ladders between June 15 and September 15 to facilitate eel migration. The eel ladder systems, developed with USFWS and NYSDEC, use a gravity siphon pump and a solar-powered pump to facilitate passage. Downstream passage is available at Johnsonville via the 20-cfs bypass flow leading to a plunge pool. Schaghticoke’s 60-cfs bypass flow provides passage as well.
The project lands consist of 1,066.3 acres across the two facilities (696.3 acres at Johnsonville, 370 acres at Schaghticoke). Project lands at the Johnsonville development are primarily forested, low-density developed, or open space. Schaghticoke lands are limited primarily to the power facilities and some forested areas. No lands of significant ecological value exist in these areas.
Threatened or endangered species potentially present in the project vicinity include bald eagle, Karner blue butterfly, and Provancher’s fleabane. Surveys conducted at the project’s concluded that the Karner blue butterfly or its host species, the blue lupine, are not found in the project area and not likely to be adversely impacted by project operations. Further, review of the NYSDEC’s Environmental Resource Mapper and the Environmental Assessment Form Mapper found that bald eagles may use the Johnsonville development for access to food and potentially to overwinter. However, operational and recreational measures do not affect the distribution or abundance of prey and no impacts on the species are expected. The Provancher’s fleabane may be found in the Schaghticoke vicinity though only in the bypass reach, if at all. The species grows on cliffs along the Hudson river and seasonally exposed bedrock of large rivers, more specifically in rocky crevices along rivers and streams where it can receive splashed water. NYSDEC only noted the presence of bald eagles in the project vicinity and does not expect any impact on the listed species.
The Schaghticoke development’s turbines, generators, dam, gates, and powerhouse are eligible for listing on the National Register of Historic Places as an example of early 20th century hydroelectric generation. The New York State Historic Preservation Office (SHPO) has noted that project operations will not impact cultural or historic resources at the project. The project owner submits annual reports to the SHPO summarizing activities relevant to the resources at the project.
Recreational resources at the project include fishing access, a car-top boat launch, canoe portage and put-in/take-out locations, whitewater releases based on annual attendance (in collaboration with American Whitewater), and an Americans with Disabilities Act compliant fishing platform. Public access is provided free of charge where safety and private property do not preclude access.
