Meromictic Lake
A meromictic lake has layers of water that do not intermix. In ordinary, "holomictic" lakes, at least once each year there is a physical mixing of the surface and the deep waters. This mixing can be driven by wind, which creates waves and turbulence at the lake's surface, but wind is only effective at times of the year when the lake's deep waters are not much colder or warmer than its surface waters.
The term "meromictic" was coined by the Austrian Ingo Findenegg in 1935, apparently based on the older word "holomictic". The concepts and terminology used in describing meromictic lakes were essentially complete following some additions by G. Evelyn Hutchinson in 1937.

Famous quotes containing the word lake:
“Such were the first rude beginnings of a town. They spoke of the practicability of a winter road to the Moosehead Carry, which would not cost much, and would connect them with steam and staging and all the busy world. I almost doubted if the lake would be there,—the self-same lake,—preserve its form and identity, when the shores should be cleared and settled; as if these lakes and streams which explorers report never awaited the advent of the citizen.”
—Henry David Thoreau (1817–1862)
