Lake Te Anau is in the southwestern corner of the South Island of New Zealand. The lake covers an area of 344 km2 (133 sq mi), making it the second-largest lake by surface area in New Zealand (after Lake Taupo) and the largest in the South Island. It is the largest lake in Australasia by fresh water volume.
The main body of the lake runs north-south, and is 65 km in length. Three large fiords form arms to the lake on its western flank: North Fiord, Middle Fiord and South Fiord. These are the only inland fiords that New Zealand has, the other 14 are out on the coast. Several small islands lie in the entrance to Middle Fiord, which forks partway along its length into northwest and southwest arms. The surface of the lake is at an altitude of 210 m. It has a maximum depth of 417 m, so much of its bed lies below sea level, with the deepest part of the lake being 226 metres below sea level.
Several rivers feed the lake, of which the most important is the Eglinton River, which joins the lake from the east, opposite the entrance to North Fiord. The outflow is the Waiau River, which flows south for several kilometres into Lake Manapouri. The town of Te Anau lies at the south-eastern corner of the lake, close to the outflow.
Most of the lake is within Fiordland National Park and the Te Wahipounamu World Heritage site, the latter of which was officially recognized internationally in 1990. Other than the Te Anau township, the only human habitation close to the lake is the farming settlement of Te Anau Downs, close to the mouth of the Eglinton River. Between these two settlements the land is rolling hill country, but elsewhere the land is mountainous, especially along its western shore, where the Kepler and Murchison Mountains rise 1,400 m above the surface of the lake.
Lake Te Anau was important for the Ngai Tahu iwi in pre-European times as the area was a traditional stopping point on their trails between the east and west coasts of the South Island of New Zealand, where they obtained food and resources. The lake was first discovered by European explorers Charles Naim and William Stephen in 1852.
