Because the continent is covered with an ice sheet, all lakes are sub-glacial. Theories are that these lakes are caused by the warmth of the Earth's core, because the liquid water is so deep beneath the ice sheet.

Not all sub-glacial lakes have been 'discovered' in Antarctica, but to date, about 400 have been identified. The largest found to date is Lake Vostok, which measures about 6,058 mi² in area, with a surface elevation of -1,640'. It is about 155.3 miles long, 31.07 miles wide and about 1,129' deep. It also has its very own island. These statistics are from its Wikipedia page.

Another lake, Lake Willians, measures about 60² Km in area, but is only about two metres deep, according to Nature. It is only 800 M below the surface of the ice sheet.

Ninety-eight percent of the continent is covered with an ice sheet. This means that all lakes -- i.e., liquid water on the continent -- are sub-glacial. Not all sub-glacial lakes have been discovered, so we don't know yet, which is the biggest.

A notable lake -- Lake Vostok, is one of about 400 that we know about, and is currently (July 2015) listed as the largest. Here are statistics about it from its Wikipedia page:

  • Area: 6,058 mi² (15,690 km²)
  • Surface elevation: -1,640' (-500 m)
  • Length: 155.3 miles (250 km)
  • Width: 31.07 miles (50 km)
  • Mean depth: 1,129' (344 m)
  • Number of islands: 1

You may be thinking of Lake Vostok, which to date is the largest known lake under the ice sheet on Antarctica.

You may be thinking of the Onyx River, a seasonal, melt-water run-off that stretches 32 miles. Because 98% of Antarctica is covered by an ice sheet, rivers only flow in summer.
