The Star Lake is a dammed lake in the west of the island Newfoundland in the Canadian province of Newfoundland and Labrador .
Reservoir
Star Lake is located on Buchan's Plateau 6 km northwest of the western end of Red Indian Lake . The catchment area of the lake covers 431 km². The original altitude was 284 m , the original lake area was 15.7 km². The Star Lake had an original maximum water depth of 21 m and an average water depth of 4.4 m. The damming of the Star Brook , the natural outflow of the lake, in 1997 made it a reservoir with an area of around 25 km². Since then, the water level has fluctuated by 8 m, with the lowest sea levels occurring at the beginning of spring. From the 600 m long dam ( ⊙ ) an approximately 1.9 km long pressure line leads to the hydropower plant. The Star Brook now only carries a small part of the original amount of water.
Star Lake Hydroelectric Power Station
The Star Lake hydroelectric power station ( ⊙ ) is located on the north shore of Red Indian Lake. It was put into operation in 1998. The power plant was built and initially operated by Star Lake Partnership , in which Abitibi-Consolidated Inc. (51 percent) and Enel North America, Inc. (49 percent) had a stake. The power plant has a vertical Francis turbine with an output of 8.4 MW. The height of fall is around 130 m.
In 2008, there was a lawsuit between Abitibi-Consolidated Inc., which operated other hydropower plants in the river system of the Exploits River , and the provincial government. The province expropriated Star Lake Partnership . In 2011 a legal agreement was reached and the previous owners received compensation. Since 2011, the power plant has been operated by Newfoundland and Labrador Hydro , a subsidiary of Nalcor Energy . The plant is still owned by the province.
Ecological consequences
The arctic char and the brook char occurred as largely isolated populations in the lake. Despite ecological concerns, the hydropower project was implemented. It is feared that the original ecosystem in the lake has been severely impaired since then.
