卡斯卡特水力發電廠計畫位於新罕布夏州柏林市和戈勒姆鎮的安德羅斯科金河上。 壩 和磨坊最初於1903年由柏林磨坊公司建造,用於為造紙活動提供水力機械動力。磨坊後來被改造成水力發電廠。 發電站 1913年至1918年間,水力機械裝置被水力渦輪機/發電機取代。水力發電於1914年首次投入使用。

安德羅斯科金河全長178英里,流經新罕布夏州和緬因州境內3450平方英里的土地。它在緬因州梅里米廷灣與肯納貝克河匯合,然後流入緬因灣,最終流入大西洋。該項目是安德羅斯科金河11英里範圍內的幾個水力發電項目之一,該河位於新罕布夏州柏林和謝爾本之間。 鋸木廠 (LIHI #173), 交叉電源 (LIHI #174), 上戈勒姆 (LIHI #175), 戈勒姆 (LIHI #153), 和 謝爾本 (LIHI #176).卡斯卡德計畫位於下游不遠處 跨電力工程(LIHI #174) 並緊鄰 上戈勒姆計畫 (LIHI #175).

大壩的構造與 1903 年相同。它是一座 583 英尺高的混凝土 重力壩 包括:

  • 15 英尺寬的混凝土 鄰接 向上游延伸約 20 英尺,向下游延伸約 30 英尺,垂直於 溢洪道,
  • 一個 弧形 洩洪道段,長 313 英尺,高 3 英尺 閃光板,
  • 前池閘門結構,長 168 英尺,寬 15 英尺。它由 15 個 3 英尺寬的混凝土墩和一個帶木 蓋茲每個寬 9 英尺,高 11 英尺,
  • 毗鄰前池閘門結構的橋台,由兩道平行的3英尺寬的混凝土擋土牆組成,牆體填土。擋土牆延伸約88英尺,其中77英尺位於河岸內陸。
  • 前池位於前池閘門結構下游,長約300英尺,寬約240英尺,最大深度約24英尺。前池牆為混凝土重力式結構,向下游延伸約326英尺。牆體最大高度為41英尺,頂部高4英尺,寬11英吋。

前池牆內有:

  • 下游約 90 英尺處有一扇深閘門。
  • 下游約 193 英尺處有一條 4 英尺寬、2.5 英尺深的水閘門。
  • 位於前池牆頂部的混凝土平台,尺寸為 19 英尺 x 24 英尺,用於支撐帶有輸電線的電塔。
  • 一座鋼框架磚砌發電廠,長 135 英尺,寬 43 英尺,高 67 英尺,附加混凝土結構,長 19 英尺,寬 24 英尺。三 壓力管道 領先於 頭 通往三座大門 弗朗西斯式水輪機 總裝置容量為 8.115 兆瓦。.

流經溢洪道的水流入一條 400 英尺長的基岩水道旁通段。

該項目運營於 徑流 mode and impounds a 28-acre reservoir. The impoundment is allowed to fluctuate over a 6-inch range. The project provides a minimum flow of 6 cfs or inflow, whichever is less, through an orifice in the spillway flashboards to provide stable habitat for resident species. This minimum flow regime was developed in consultation with the US Fish and Wildlife Service and New Hampshire Fish and Game Department.

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 fish species in the project reach due to downstream natural falls – Lewiston and Rumford Falls, in the Maine portion of the river. 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 limited project lands consist of those associated with project structures. The project is surrounded by low density residential and commercial development out the outskirts of the City of Berlin. The project’s run-of-river operations provides protection of the shoreline areas. The project is also subject to the New Hampshire Shoreland Water Quality Protection Act which governs shoreland uses within a 250-foot buffer of the high-water mark.

Threatened or endangered species potentially present in the project vicinity include northern long-eared baty, Canada lynx, and the proposed for listing tri-colored bat and monarch butterfly. The project avoids removing trees from April 15 through October 31, unless emergency tree removal for public safety is necessary.

The project’s dam and powerhouse are eligible for listing on the 國家歷史遺跡名錄 (NRHP). No Native American lands, known as traditional cultural properties, or NRHP-eligible tribal resources are present within the Project boundary. The project operates under a Programmatic Agreement (PA) in consultation with the State Historic Preservation Office. The PA and related Historic Properties Management Plan (HPMP) provides provisions detailing annual monitoring and reporting concerning repair and improvement activities conducted as well as any scheduled activities for the upcoming year.

No recreational resources are provided in the project’s limited area. However, an impoundment access area is owned and operated by the City of Berlin outside the Project boundary. This area provides scenic views, a gravel hand-carry boat access, and bank and boat fishing.
