Salvatnet[2] is a lake in the municipalities of Namsos and Nærøysund in Trøndelag county, Norway. With its deepest depth of 464 metres (1,522 ft), it is Norway's and Europe's second-deepest lake, after Hornindalsvatnet. Alternate sources give the depth as either 464 metres (1,522 ft) or 482 metres (1,581 ft) at the deepest point. The lake sits very close to the ocean, about 9 metres (30 ft) above sea level at the surface and reaches to a depth of 455 metres (1,493 ft) below sea level. It is a very large lake with an area of 44.77 square kilometres (17.29 sq mi), a volume of 6.87 cubic kilometres (1.65 cu mi), and a shoreline that is 105.61 kilometres (65.62 mi) around.[3]

Salvatnet is a meromictic lake, meaning that the water is permanently stratified, often without oxygen in the lower depths (bottom water) due to density gradient and a lack of turnover. A meromictic lake often preserves records of the geologic past. The lower layer of the lake is highly saline and as a result denser than the higher levels of water. Other meromictic lakes in Norway with old seawater in the lower depths include Kilevann, Tronstadvann, Botnvatnet, Rørhopvatnet, and Rørholtfjorden.

Salvatnet[1] (oder Salvatn[2]) ist der Name eines norwegischen Sees in den Kommunen Namsos und Nærøysund in der Provinz Trøndelag. Mit der tiefsten Stelle (464 m) ist er Norwegens und Europas zweittiefster See nach dem Hornindalsvatnet. Andere Quellen nennen 482 m als tiefste Stelle. Es handelt sich um einen meromiktischen See – einen See, bei dem in der Regel kein Wasseraustausch zwischen den oberen und tieferen Schichten stattfindet.
