The lake drained below the Herman lake beaches until isostatic rebound and glacial advances closed the Kaministikwia route. This stabilized the lake at the Norcross lake stage (325 metres (1,066 ft)). [1] [21] The average depth of Lake Agassiz during the late Moorhead Phase was 258 metres (846 ft). Drainage from Lake Agassiz continued to flow ...
Lake Vida is one of the largest lakes in the McMurdo Dry Valley region and is a closed-basin endorheic lake. The permanent surface ice on the lake is the thickest non-glacial ice on earth, reaching a depth of at least 21 metres (69 ft). The ice at depth is saturated with brine that is seven times as saline as seawater. [1]
However, because it is also the deepest lake, [6] with a maximum depth of 1,642 metres (5,387 feet; 898 fathoms), [1] Lake Baikal is the world's largest freshwater lake by volume, containing 23,615.39 km 3 (5,670 cu mi) of water [1] or 22–23% of the world's fresh surface water, [7] [8] more than all of the North American Great Lakes combined.

Therefore, mean depth figures are not available for many deep lakes in remote locations. [9] The average lake on Earth has the mean depth 41.8 meters (137.14 feet) [9] The Caspian Sea ranks much further down the list on mean depth, as it has a large continental shelf (significantly larger than the oceanic basin that contains its greatest depths).
Boise State University associate professor Hans-Peter Marshall poses at the the field site where researchers are studying snow and ice depth, alongside a radar system used for research and mounted ...
While the average depth of the lake is 139 ft (42 m), its greatest depth is at least 394 ft (120 m). [1] Yellowstone Lake is the largest freshwater lake above 7,000 ft (2,100 m) in North America. [2] In winter, ice nearly 3 ft (0.91 m) thick covers much of the lake except where shallow water covers hot springs.
Lake Vostok (Russian: озеро Восток, romanized: ozero Vostok) is the largest of Antarctica's 675 known [3] subglacial lakes.Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level.
In 2019, the last big ice year, the maximum amount of seasonal ice covered about 81% of the surface of the Great Lakes, Kessler said. This season, hardly any formed.
