Lake Wakatipu
Lake Wakatipu () is an inland lake (finger lake) in the South Island of New Zealand. It is in the southwest corner of the Otago region, near its boundary with Southland. "Lake Wakatipu" comes from the original Māori name "Whakatipu wai-māori". With a length of , it is New Zealand's longest lake, and, at , its third largest. The lake is also very deep, its floor being below sea level, with a maximum depth of . It is at an altitude of , towards the southern end of the Southern Alps / Kā Tiritiri o te Moana. The general topography is a  reversed "N" shape or "dog leg". The Dart River / Te Awa Whakatipu flows into the northern end, the lake then runs south for 30 kilometres before turning abruptly to the east. Twenty kilometres (12.4 mi) further along, it turns sharply to the south, reaching its southern end further south, near Kingston. The lake is drained by the Kawarau River, which flows out from the lake's only arm, the Frankton Arm, east of Queenstown. Until about 18,000 years ago the Mataura River drained Lake Wakatipu. The Kingston Flyer follows part of the former river bed now blocked by glacial moraine . Queenstown is on the northern shore of the lake close to eastern end of its middle section. It has a seiche of period 26.7 minutes which, in Queenstown Bay, causes the water level to rise and fall some . Lake Wakatipu is renowned for its scenic beauty, as it is surrounded by mountains. Two mountain ranges, the Remarkables and the Tapuae-o-Uenuku / Hector Mountains, lie along its southeastern edge. It is a popular venue for adventure tourism, with skifields, paragliding, bungy jumping and tramping tracks within easy reach. A vintage steamboat, the TSS "Earnslaw" regularly plies its waters. Several vineyards  are nearby in Gibbston. Etymology. The full original name of the lake is "Whakatipu-wai-Māori". While the lake lacks an official name, it is generally referred to as "Lake Wakatipu". The name is believed to originate from the Waitaha people, who were later displaced by Kāti Māmoe. Elders from the modern iwi Ngāi Tahu say that while the name Whakatipu is archaic and its original meaning is a mystery, "whaka" means causative and "tipu" means growth. Wakatipu could mean "growing bay" if the original was Whakatipu and the h elided as a result of the Southern Māori dialect. The  dialect is also known for dropping final vowels. "Waka" can also mean 'hollow'. Wakatipua or Whakatipua (Canoe/Bay of spirits) have been recorded historically, as has Wakatapu (sacred vessel). Whakatipu is also the name of another six unrelated geographical features in the South Island, including "Tarahaka Whakatipu", the Harris Saddle at the head of the Routeburn Track; "Whakatipu Katuka", the Hollyford River and Valley; and "Whakatipu Kohurangi", Māori Bay in Pelorus Sound, Marlborough. A legend says that the lake bed was formed when a giant ogre, Kopu-wai, was burned while lying asleep, leaving only his heart behind, which according  to the same legend is the cause of the rhythmic rise and fall of the lake's seiche. Flooding. Lake Wakatipu has experienced periodic flooding affecting the lakeside communities of Kingston, Glenorchy and Queenstown. Notable flooding events include the 1878 Queenstown floods, which affected a large part of the outlying Queenstown and Otago areas, the 1995 Queenstown floods, and most notably the 1999 Queenstown floods, which significantly damaged the Queenstown CBD and road infrastructure resulting in approximately $50 million worth of damage. Wildlife. Lake Wakatipu is a habitat for the longfin eel (a specimen caught in 1886 is the  largest known of this species), brown trout, salmon and rainbow trout. These and other fish support predators such as the pied shag. The black-billed gull is often found around the lake while the most common birds are the black-billed gull and the introduced mallard. A smaller bird often not noticed because of its size is the New Zealand scaup. In popular culture. Film. Lake Wakatipu doubled as the Scottish Loch Ness in the 2007 film "". The lake was a backdrop for several scenes in "", including Amon Hen. Television. Lake Wakatipu is the eponymous lake in the murder mystery  television series "Top of the Lake" (2013).
