Torneträsk originated from the remnant of a glacier, which has given the lake its depth of 168 metres (551 feet), making it the second-deepest lake in Sweden. It is usually ice-covered from December through June, with variations dependent on temperature variations.
Permafrost is common in the land around the lake. This low elevation permafrost is disappearing because of global warming and increased snowfall.[3]
During the 1944 Operation Obviate of WWII, British bombers seeking to destroy the German battleship Tirpitz had their rendezvous over Torneträsk, in violation of Swedish neutrality.
