Tinnsjå (Tinnsjø, Tinnsjøen) is a major Norwegian lake -- the 3rd deepest, 6th largest by volume and 20th largest in surface area in the country. A lake (from Latin lacus) is a Terrain feature (or Physical feature) a body of Liquid on the surface of a world that is localized to the There are at least 450000 fresh water Lakes in Norway. Fewer than 400 have an area of more than 5 km2. It is located between the municipalities of Tinn and Notodden in Telemark county. Tinn is a municipality in the county of Telemark Norway. The parish of Tin was established as a municipality January 1 1838 (see Formannskapsdistrikt is a city and municipality in the county of Telemark, Norway. is a county in Norway, bordering Vestfold, Buskerud, Hordaland, Rogaland and Aust-Agder. On its source: From the west, the Måna river flows out of Møsvatn and past Rjukan into Tinnsjå.

The Norwegian heavy water sabotage was a series of actions taken by Norwegian saboteurs during World War II to prevent the German nuclear energy project from acquiring 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. Heavy water is water which contains a higher proportion than normal of the Isotope Deuterium, as deuterium oxide, D2O or ²H2O The heavy water had been produced at Vemork, a factory located in Rjukan. Vemork is the name of an hydroelectric Power plant outside Rjukan in Tinn, Norway. Rjukan is a city and the administrative center of Tinn municipality in Telemark. The wreck of the ferry was discovered in 1993.

In April 2005, a previously unknown species of fish was discovered in Tinnsjå.
