Which lake is Europe’s deepest, reaching about 514 metres?

Hornindalsvatnet is Europe’s deepest lake, reaching about 514 metres.

Hornindalsvatnet is a freshwater lake in Vestland county, Norway. Its maximum depth is approximately 514 metres, making it deeper than any other lake in Europe. The lake is about 22 kilometres long and has a surface elevation of roughly 53 metres above sea level, so its deepest point extends well below sea level.

The lake lies near the village of Grodås and is surrounded by steep Norwegian mountain scenery. Its water is unusually clear because relatively little glacial sediment enters the lake. This clarity distinguishes it from many Norwegian lakes whose inflowing streams carry fine rock flour produced by glaciers.

Hornindalsvatnet is sometimes confused with Lake Como or Lake Garda, which are famous deep lakes in Italy. Those lakes are impressive but shallower: Lake Como reaches about 425 metres, while Lake Garda reaches about 346 metres. Hornindalsvatnet’s extreme depth reflects the deep, glacially shaped valleys of western Norway.
