The Upper Gorham 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 upstream projects: 交叉電源 (LIHI #174), Cascade (LIHI #188)鋸木廠 (LIHI #173), and two downstream projects: 戈勒姆 (LIHI #153), 和 謝爾本 (LIHI #176).

該項目包括 originally constructed in 1904, power 運河, 發電站, four turbines, and transmission equipment. The dam is 775 feet long with a maximum height of 31feet and is comprised of:

  • A 133-foot-long earthen dike with a concrete core wall.
  • A 300-foot-long by 18-foot-high rock-filled and timber-crib 溢洪道 section with 5-foot-high 閃光板.
  • A 122-foot-long power canal gate section, topped with a gatehouse 113 feet long by 16 feet wide, with eight operable and two inoperable stop-log 蓋茲, each approximately 7.5 feet wide. Trashracks have 3 1/8-inch clear spacing.
  • A 220-foot-long earthen dike with a concrete core wall.

The power canal is 3,350-foot long, 100 feet wide and 18 feet deep. The brick and steel powerhouse contains four horizontal generators and four horizontal 弗朗西斯式水輪機 for a total combined capacity of 4.8 MW.

該項目以準徑流 mode and impounds a 45-acre reservoir. The impoundment is allowed to fluctuate over a 6-inch range. The project provides a minimum flow of 400 cfs into the 1-mile-long bypass reach throughout trout spawning season (March 1 – June 15) to optimize trout habitat. The rest of the year a 200 cfs minimum flow is provided. This was increased from 50 cfs due to increased demand in angler activity. This flow regime was developed in consultation with US Fish and Wildlife Service (USFWS) and the New Hampshire Department of Environmental Services (NHDES).

工程範圍內的水域定為B類水域,適合釣魚、主要接觸娛樂活動以及處理後供水。由於先前有幾家造紙廠排放污染物,該計畫水體被列為受損水體。鑑於徑流式運作方式,該計畫不太可能對水質產生不利影響。

安德羅斯科金河無法到達 洄游性 項目河段內的魚類種類。由於下游有天然瀑布——劉易斯頓瀑布和朗福德瀑布,該地區沒有鯡魚、藍背鯡魚、鱸魚、七鰓鰻和美洲西鯡等物種。安德羅斯科金河下游有美洲鰻,但歷史上從未有美洲鰻到達該河的上游。計畫區支持冷水漁業棲息地。新罕布夏州魚類和野生動物管理局每年都會在計畫上游放養溪鱒魚、虹鱒魚和褐鱒魚。常駐河流物種包括秋魚、小嘴鱸魚、白吸盤魚、長吻鰷、普通鯔魚、斑尾鯔魚和黃鱸魚。下游通道可透過溢洪道水流、低位閘門洩洪以及透過攔污柵的動力取水流來實現。該項目不會妨礙當地魚類生命週期的成功完成。

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.

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。

Non-project recreational resources at the project include an Appalachian Mountain Club trail and bicycle trails. Public access is provided free of charge where safe access is available.
