Warm Monomictic Lakes
Warm monomictic lakes are lakes that never freeze, and are thermally stratified throughout much of the year. The density difference between the warm surface waters (the epilimnion) and the colder bottom waters (the hypolimnion) prevents these lakes from mixing in summer. During winter the surface waters cool to a temperature equal to the bottom waters. Lacking significant thermal stratification, these lakes mix thoroughly each winter from top to bottom. These lakes are widely distributed from temperate to tropical climatic regions. One example is South Australia's Blue Lake, where the change in circulation is signaled by a striking change in colour.

Famous quotes containing the words warm and/or lakes:
“Something of vengeance I had tasted for the first time; as aromatic wine it seemed, on swallowing, warm and racy: its after- flavour, metallic and corroding, gave me a sensation as if I had been poisoned.”
—Charlotte Brontë (1816–1855)
“It was inspiriting to hear the regular dip of the paddles, as if they were our fins or flippers, and to realize that we were at length fairly embarked. We who had felt strangely as stage-passengers and tavern-lodgers were suddenly naturalized there and presented with the freedom of the lakes and woods.”
—Henry David Thoreau (1817–1862)
