Menihek Hydroelectric Generating Station

The power development is located approximately {{convert|170|km|mi|-1|abbr=on}} north of Labrador City, Labrador,{{sfn|Newfoundland and Labrador Hydro|2008|}} in an uninhabitated region in the northwestern tip of Labrador. The station is just south of the Laurentian Divide between the Atlantic and Arctic drainage basins which delineates the Quebec–Newfoundland and Labrador border in the area.

The climate in Schefferville, {{convert|40|km|mi|0|abbr=on}} north of Menihek, is characterized by an average temperature of {{convert|-5.3|C|F|abbr=on}} — which can drop as low as {{convert|-51|C|F|abbr=on}} in the winter and rise to {{convert|34|C|F|abbr=on}} in the summer. The average frost-free period lasts from mid-June to mid-September. The area receives on average {{convert|833|mm|in|1|abbr=on}} of precipitation, roughly divided between rain and snow.{{harvnb|Envir-Eau|2009|p=9}}

The terrain in this remote area is rugged and the dam is only accessible by a narrow Gravel road from Schefferville or Tshiuetin Rail Transportation railway.

The facilities, including Menihek Aerodrome, were built between 1951 and 1954 by the Iron Ore Company of Canada to meet the power requirements of its iron ore mining operations at the Knob Lake site, near the company town of Schefferville. After IOC closed the mine in 1982, it kept the generating station running for two decades. However, in the early 2000s, the mining company gave notice to the Government of Quebec that it would cease to operate the plant and electric network as of November 1, 2002. In a last-minute deal, Hydro-Québec agreed to pay for all charges incurred by IOC to run the money-losing network while the governments of Quebec and Newfoundland and Labrador and First Nations communities tried to reach a deal on a mutually acceptable way to split the assets.{{sfn|Hydro-Québec Distribution|2006|p=10-11}}

An agreement was reached by the two provinces and their respective utilities on December 14, 2005.{{sfn|Hydro-Québec Distribution|2006|p=12}} IOC would sell all interests in the generating station and part of the transmission lines to provincially owned Newfoundland and Labrador Hydro (NLH), as is, for $1, while transferring its Quebec utility operations to Hydro-Québec for the same amount. Under the deal, the generating station would be operated by NLH employees, but it would be managed by a 4-person operating committee staffed by personnel of both utilities.{{sfn|Hydro-Québec Distribution|2006|p=18-20}}

The power development at the Menihek site includes a {{convert|228.6|m|ft|0|abbr=on}} concrete gravity dam, a water intake, powerhouse and a 4-gate spillway, with a capacity of {{convert|4247|m3/s|ft3/s|-2|abbr=on}}.{{sfn|RSW Inc.|2001|p=24}}

The impoundment of Menihek Lake, which serves as a reservoir, is completed by three rock-fill dikes made of glacial till, for a total length of {{convert|6.2|km|mi|0|abbr=on}}. The Tshiuetin Rail Transportation shortline railway (formerly the Menihek Subdivision of the Quebec North Shore and Labrador Railway) connecting Schefferville and Sept-Îles uses the dikes to cross the area.{{sfn|Cloutier et al.|2002|p=26}}

The powerhouse was designed to receive four generating units but only two were installed when the plant came on stream in 1954. Units 1 and 2 are equipped with Francis turbines and each have a capacity of 4,400 kW at a nominal hydraulic head of {{convert|10.4|m|ft|0|abbr=on}}. Each turbine is coupled to a 5,000 kVA alternator. In 1960, IOC added unit 3, a 9,900-kW Kaplan turbine under a {{convert|12|m|ft|0|abbr=on}} head and its 12,000 kVA alternator.{{sfn|RSW Inc.|2001|p=24}}

Menihek Aerodrome is an abandoned airport located on the east coast of Menihek Lake, Labrador, Canada.

The airport was built between 1951 and 1952 by the Iron Ore Company of Canada to service the Menihek Hydroelectric Generating Station built to meet the power requirements of its iron ore mining operations at the Knob Lake site, near the company town of Schefferville.

On 28 July 1953 an Avro 683 Lancaster (registration CF-GBA) of World-Wide Airways crashed upon landing while on a cargo flight from Sept-Îles Airport. The airplane was carrying a cargo of 8100 litres of diesel, 1135 litres of gasoline, and 3000 litres of avgas. The approach was performed in strong crosswinds and after landing the airplane veered out of control and collided with rocks at the end of the runway. Both pilots evacuated without injury while the aircraft caught on fire and was destroyed.{{cite web | url=https://www.baaa-acro.com/crash/crash-avro-683-lancaster-i-menihek | title=Crash of an Avro 683 Lancaster I in Menihek | Bureau of Aircraft Accidents Archives }}
