Lake Neusiedl

Lake Neusiedl (German: Neusiedler See) or Fertő (Hungarian: Fertő tó; Croatian: Nežidersko jezero, Niuzaljsko jezero; Slovene: Nežidersko jezero) is the largest endorheic lake in Central Europe, straddling the Austria-Hungarian border. The lake covers 315 km², of which 240 km² is on the Austrian side and 75 km² on the Hungarian side. The lake's drainage basin has an area of about 1,120 km². From north to south, the lake is about 36 km long, and it is between 6 km and 12 km wide from east to west. On average, the lake's surface is 115.45 m above the Adriatic Sea and the lake is no more than 1.8 m deep.

Water level fluctuations

In the past, rainfall and aridity caused significant floods (which in 1768 enlarged the lake to its maximum documented size of 515 km²) and significant decreases in the lake's level, although frequently there seemed to be no apparent connection with the weather situation.
