Tinnsjå
At the north end of the lake lie the villages of Atrå and Austbygdi. The village of Miland lies on the western shore of the lake. The village of Hovin lies up on a hill overlooking the eastern shore of the lake and the village of Rudsgrendi lies on the western shore. There is a small dam at the south end of the lake which regulates the surface elevation of the lake and the village of Tinnoset is located at this end of the lake. The village of Gransherad lies about 4 km (2.5 mi) south of this dam.
History
In 1944, during the German occupation of Norway, the ferry SF Hydro was sunk in Tinnsjå by the Norwegian resistance. The Germans were using the ferry to transport a large quantity of heavy water to Germany, where it was to be used for nuclear weapons research. The heavy water had been produced at Vemork, a factory located in Rjukan.
The wreck of the ferry was discovered in 1993. In 2004, it was investigated and filmed for an episode of NOVA; heavy water samples were recovered and deuterium isotopic enrichment was confirmed.
In 2004, a film crew shooting footage for a new documentary on the heavy water sabotage became aware of an unusual fish, swimming near the lake bottom at a depth of 430 metres (1,410 ft). Two specimens of the previously unknown fish were captured in April 2005. Analysis revealed the fish to be closely related to Arctic char. The light-colored, translucent fish is up to 15 centimetres (5.9 in) long and lacks a swim bladder.
