The Shelburne Project is located on the Androscoggin River in Coos County, northern New Hampshire. The Androscoggin River is runs through the states of New Hampshire and Maine. The river joins the Kennebec River at Merrymeeting Bay in Maine before emptying into the Gulf of Maine and subsequently the Atlantic Ocean. The Androscoggin River watershed contains 19 hydroelectric projects located along the 178-mile-long river.
The Project is the most downstream of several hydroelectric projects within an 11-mile reach of the Androscoggin River between Berlin and Shelburne, New Hampshire, including Upper Gorham (LIHI #175), Gorham (LIHI #153), Cascade (LIHI #188), Cross Power (LIHI #174)， 和 Sawmill (LIHI #173).
該項目包括 壩 originally constructed in 1903, 發電站, three turbines, and transmission equipment.
The dam is 551 feet long with a maximum height of 17.5 feet and is comprised of:
- Non-overflow dam sections totaling 146 feet in length.
- A171-foot-long 溢洪道 with an 83-foot-long section topped by 9-foot-high 閃光板 and an 88-foot section containing three 25-foot-wide waste 蓋茲.
- A 27-foot-wide sluiceway adjacent to the waste gates, controlled by a 19-foot-wide sluice gate.
- A 17-foot-long by 14-foot-wide building housing the gate controllers located on the island adjacent to the sluiceway wall.
- A 95-foot-long concrete retaining wall located between the sluiceway and the powerhouse.
The powerhouse is constructed of brick and steel framing on top of nine 4-foot-wide concrete piers, each integral with the dam. The upstream face of the powerhouse is flush with the upstream face of the dam. The powerhouse contains a 15-foot-deep by 112-foot-long intake with 3-inch clear spacing trashracks and three vertical Francis turbines with a combined capacity of 3.72 MW.
The project operates in a quasi-徑流 mode and impounds a 250-acre reservoir. The impoundment is allowed to fluctuate over a 6-inch range. The project provides a minimum flow of 2 cfs into the short bypassed reach. This flow regime was developed in consultation with US Fish and Wildlife Service (USFWS) and the New Hampshire Department of Environmental Services (NHDES).
Waters within the project reach are designated as Class B, suitable for fishing, primary contact recreation, and water supply after treatment. The project waters are listed as impaired due to prior discharges from several paper mills. Given run-of-river operations, the project is unlikely to adversely impact water quality.
The Androscoggin River is not accessible to 洄游性 fish species in the project reach. Species such as alewife, blueback herring, striped bass, sea lamprey, and American shad are not present in the area due to downstream natural falls – Lewiston and Rumford Falls. American eel are present in the lower reaches of the Androscoggin River though none have historically reached the upper sections of the river. The project area supports cold-water fishery habitat. New Hampshire Department of Fish and Game annually stocks brook, rainbow, and brown trout upstream of the projects. Resident river species include fallfish, smallmouth bass, white sucker, longnose dace, common shiner, spottail shiner, and yellow perch. Downstream passage can occur by means of spillway flow, low-level gate releases, and power intake flow through the trashracks. The project does not impede the successful completion of resident fish life cycles.
The project lands are limited to the area occupied by project infrastructure. A shoreline protection plan was developed for the project to establish a 250-foot buffer from the shoreline. The plan provides provisions for land uses and planting/vegetation removal standards within the buffer. The plan is consistent with New Hampshire’s Shoreland Protection Act. Further, the project’s run-of-river operations provides protection of the shoreline areas.
Threatened or endangered species potentially present in the project vicinity include the Northern long-eared bat, Canada lynx, eastern small-footed bat, little brown bat, tri-colored bat, bald eagle, Cape May warbler, evening Grobeak, rusty blackbird, wood thrush, wood turtle, American marten, peregrine falcon, and common nighthawk. Plant species include auricled twayblade, mountain sweet-cicely, ovoid spikesedge, parasol sedge, pink shinleaf, purple virgin’s-bower, round-leaved orchid, smooth cliff fern, dwarf blueberry, fragrant wood fern, heart-leaved twayblade, and Hornemann’s willow-herb.
The listed bat species are not likely to be impacted by project operations as there are generally no tree-clearing activities or corridor maintenance activities. Some vegetation removal and maintenance occur to ensure dam safety but said activities adhere to the USFWS 4(d) rule concerning habitat protection for the bat species. Most of the other listed species have been noted in the project vicinity but run-of-river operations and impoundment fluctuation limits mitigate any impact on these species.
The project area does not support any known historic or cultural resources. However, the project operates under a Programmatic Agreement (PA) in consultation with the State Historic Preservation Office. The PA provides provisions detailing annual monitoring and reporting concerning repair and improvement activities conducted as well as any scheduled activities for the upcoming year.
Recreational resources at the project include interpretative signage detailing the history of the project. Public access is provided free of charge.
