Lake Tinn

Lake Tinn (Norwegian: Tinnsjå, Tinnsjø, Tinnsjøen) is one of the largest lakes in Norway, and one of the deepest in Europe. It is located between the municipalities of Tinn and Notodden in Telemark county. At its source in the west, the Måna river flows out of Møsvatn and past Rjukan into Tinnsjå. From the north, the river Mår flows from the Mår, Gøystavatn, and Kalhovdfjorden lakes into Lake Tinn. Lake Tinn is part of the Skiensvassdrag, and drains via the Tinnelva river in the south, down to Heddalsvatn.

In 1944, during the German occupation of Norway, the ferry SF Hydro was sunk in Lake Tinn 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 weapon 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.
