Like a Lake eh
When determining the largest of lakes, one opens the floodgates. I can safely disregard the need to document the highest lake but the deepest and the longest come into play. As it happens, among these worldbeaters are both - Lake Baikal is the deepest lake, and Lake Tanganyika (which has not had an update in its name like the country it borders, along with Burundi, Zambia, and the Democratic Republic of Congo) the longest.
Michigan - Huron
Great Bear Lake
Great Slave Lake
If the bilge pump that is this blog has any idea why the list stops at Winnipeg, you'd have to interrogate the wiki editing process, as it is much longer than this now. But these are the Great Lakes of North America, tussling over whether Lake Michigan and Lake Huron are separate bodies of water, in which case Lake Superior is well named. The Caspian Sea is sitting unsteadily on top with constant accusations that it is, as its name suggests, a small ocean.
Russia and Africa manage the monumental in most respects and this also applies to lakes.
The largest lake in South America is the delightfully titled Lake Titicaca
Europe's largest is Lake Ladoga
In Anarctica there is the sub glacial lake Lake Vostok
Oceania, Lake Eyre when flooded.
