    The Granasjøen Dam was constructed in 1982 as part of the extensive development of the Orkla and Grana river systems for hydroelectric power. Its construction was met with considerable local and environmental opposition before and after its approval in 1978. Protests stemmed from concerns about nature conservation and the impact on local agriculture, as the damming led to the inundation of a cultivated agricultural area and submerged numerous farm buildings and cabins. Despite the protests, it became a crucial part of the Grana power plant.
