LIHI Certificate #27- West Branch St. Regis Hydroelectric Project, New York
The 6.8-MW West Branch St. Regis River Hydroelectric Project provides an average annual generation of 34,730 megawatt-hours. Erie has generally operated the project in a pulsing mode and proposes to continue to do so.
The West Branch St. Regis River Project consists of the Parishville development and the Allens Falls development. The Parishville development consists of a dam, a 70-acre reservoir, a 2,561-foot-long penstock, a powerhouse housing a 2.4-MW turbine/generator unit, a 4,175 foot bypass reach, a 4.8-kV transmission line, and associated facilities. The Allens Falls development consists of a concrete gravity-type dam, a 108-acre reservoir, a 9,344-foot-long pipeline, a surge tank, an 886-foot-long penstock, a powerhouse housing a 4.4-MW turbine/generator unit, a 13,700 foot bypass reach, a 2.4-mile-long 115-kV transmission line, and associated facilities.
The Parishville and Allens Falls developments were originally built in the 1920s, but were required to obtain a license only after a 1988 finding by FERC that the West Branch of the St. Regis River is a navigable waterway. The developments’ owner at the time, Niagara Mohawk Power Corporation, applied for separate licenses for each development in 1990. The upstream Parishville development discharges into the Allens Falls development impoundment, and the two are operated in an integrated fashion in a storage-and-release pulsing mode. In its 2001 license order FERC granted the request of Erie Boulevard Hydropower, Niagara Mohawk’s successor, to consolidate the developments into one project. Brascan Power NY is the current owner of Erie Boulevard Hydropower.
According to the FWS, the West Branch of the St. Regis River supports a mixed cool water-warm water fishery, with the more abundant game species being brook trout, brown trout, smallmouth bass, and rock bass. The Settlement Agreement describes the project area as being located “in an area of transition between cold water fisheries in the headwaters (Adirondack Mountain Region) and the cool/warm water fisheries downstream (St. Lawrence River Lowlands)” with “[s]everal significant waterfalls…within the Project’s footprint which historically limited migration between these two regions.”
The FERC license for the Project was achieved through the use of a settlement agreement amongst the parties. The Settlement incorporates agreements reached among the parties with regard to the Parishville and Allens Falls developments. The parties provide in the settlement agreement recommended terms and conditions for the resolution of operational, fisheries, wildlife, water quality, and recreational issues raised by and analyzed by the parties as they are applicable to the issuance of a license and water quality certification for the West Branch St. Regis River Hydroelectric Project's Parishville and Allens Falls developments.
The Settlement Agreement further notes that both impoundments contain and are managed for predominantly warm water fisheries, but that the bypass reaches below each are intended, in the case of the upstream Parishville project, “to be managed as a mixed coldwater/warmwater fishery to the extent practical,” and in the case of the Allens Falls project, “as a coldwater fishery.” For these reasons, state and federal fisheries managers do not want to encourage fish movement between the developments beyond that which already existed at the time of licensing. The natural Allens Falls represent a historic barrier to anadromous fish passage up the West Branch St. Regis River.
Highlights of the Settlement Agreement: The FERC license provisions reflect the terms and conditions of a settlement agreement entered into by the applicant and the Adirondack Mountain Club, American Rivers, American Whitewater, the New York State Conservation Council, the New York State Department of Environmental Conservation (DEC), New York Rivers United, St. Lawrence County, the Town of Parishville, Trout Unlimited, and the U.S. Fish and Wildlife Service (FWS). The provisions include “mitigation and protections measures to increase habitat gains for fish communities, the potential for benthic invertebrate and forage fish production increases, enhanced fish movement and fishing opportunities, increased habitat for riparian vegetation, wetland and wildlife resources, the reduction of the vulnerability of fish to illegal poaching, increased recreational access, enhanced awareness of cultural resources, and the establishment of a river advisory council and enhancement fund.” The Settlement Agreement contains other binding provisions that are not included in the FERC license related to public access and recreation, including the requirement to transfer a parcel of land to the Town of Parishville.
The most significant element of the Settlement Agreement is the restoration of flows to the bypassed reaches below each development that had been periodically dewatered for decades, returning both to functional year-round river reaches and creating the possibility of restoring a permanent fishery. The provisions on daily and seasonal impoundment fluctuations are designed to maintain existing shallow water littoral and wetland habitat while preserving the required instream flows to the bypassed reaches. The Settlement Agreement also includes a focus on maintaining and somewhat improving public access to the project areas for recreation, and provides for the establishment of a St. Regis River Fund to underwrite natural resource protection and restoration projects, as well as recreation projects; the fund is overseen by a new West Branch St. Regis River Advisory Committee (SRRAC).

March 15, 2016: LIHI Executive Director Michael J. Sale, using authority delegated from the LIHI Governing Board, has certified that the West Branch St. Regis Hydroelectric Project (FERC No. P-10461) continues to satisfy the LIHI Certification Criteria. A Preliminary Decision was announced on February 10, 2016, and a 30-day appeal period was open through March 10, 2016. No requests for appeal were received. This Certification Decision includes the following facility-specific condition, as follows:
- Condition No. 1: Should the maintenance activities along the powerhouse roadway and pipeline right-of-way be significantly altered, such as widespread herbicide application, widening of the roadway or placement of fill adjacent to the roadway where the plant has been observed, the facility owner shall consult with the NYDEC regarding potential impacts to the Fernald’s Sedge. If such change occurs during this LIHI certification term, the facility owner shall provide LIHI the results of these consultations along with evidence of implementation of any requirements mandated by the NYDEC to protect this species if it is onsite. The owner shall report on any such changes with the LIHI Annual Compliance Statement for the subject annual statement period.
