The Cross Power 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 one of several hydroelectric projects within an 11-mile reach of the Androscoggin River between Berlin and Shelburne, New Hampshire, including the upstream Sawmill Project (LIHI #173) and downstream projects: Cascade (LIHI #188), 上戈勒姆 (LIHI #175), 戈勒姆 (LIHI #153)， 和 謝爾本 (LIHI #176).
The Cross Power 壩 was originally constructed in 1903. It is 566 feet long with a maximum height of 20 feet and is comprised of:
- Concrete non-overflow sections adjoined to a ledge outcropping. One section contains a stop-log opening used to pass accumulated debris. The other section is located from the outcropping to the 溢洪道.
- A 276-foot-long spillway section with newly designed 42-inch-high 閃光板 installed in the fall of 2020.
- A gatehouse 19 feet wide by 124 feet long with five bays. Each bay contains trashracks 21.6 feet wide by 18.4 feet-high with 3-inch clear spacing.
- A concrete retaining wall extending from the gatehouse to the river embankment.
這 發電站 is located 44 feet downstream of the gatehouse. The powerhouse is a concrete substructure with brick superstructure with an addition on the downstream shore side containing five horizontal propeller turbines with a total installed capacity of 3.22 MW.
The project operates in quasi-徑流 mode and impounds a 22-acre reservoir. The impoundment is allowed to fluctuate over a 6-inch range. Since the bypass reach is very short, the powerhouse is essentially integral to the dam, and due to backwatering from the downstream Cascade Project, no minimum flow release is specified. The flow regime was developed in consultation with US Fish and Wildlife Service (USFWS) and the New Hampshire Department of Environmental Services.
Waters within the project reach are designated Class B, suitable for fishing, primary contact recreation, and water supply after treatment. The project waters are listed as impaired for prior discharges from several paper mills. Given run-of-river operations, the project is unlikely to adversely impact water quality.
安德羅斯科金河無法到達 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 project. 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. The project’s run-of-river operations and limited impoundment fluctuation provides protection for 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 grosbeak, 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.
由於通常沒有清理樹木活動或走廊維護活動，因此列出的蝙蝠物種不太可能受到專案運作的影響。為了確保水壩安全，我們會移除一些植被並進行維護，但上述活動符合美國魚類和野生動物管理局關於蝙蝠棲息地保護的 4(d) 規定。大多數其他列出的物種都已在計畫附近被發現，但徑流作業和蓄水波動限制減輕了對這些物種的影響。
項目區域不存在任何已知的歷史或文化資源。不過，該計畫是在與國家歷史保護辦公室協商後，按照計畫協議 (PA) 運作的。 PA 提供了詳細說明已進行的修復和改進活動以及來年任何計劃的活動的年度監測和報告的規定。
Recreational resources at the project include a tailrace fishing area. Public access is provided free of charge.
合規狀態
