Tinnsjå (Tinnsjø, Tinnsjøen, Lake Tinn) is one of the largest
lakes in Norway. 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 to join the Måna river before entering Tinnsjå. Tinnsjå 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 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 weapon research. The heavy water had been
produced at Vemork, a factory located in Rjukan. The wreck of the ferry
was discovered in 1993.[2] In 2004, it was investigated and filmed for
an episode of NOVA; heavy water samples were recovered and deuterium
isotopic enrichment was confirmed.
In April 2005, a previously unknown species of fish was discovered in
Tinnsjå. 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 m. The light-colored, translucent fish was
about 15 cm long and seemed to lack a swimming bladder.
Tinnsjå's primary sources are the rivers Måna and Mår.
