Mixing typically occurs during the spring and autumn, when the lake is \"isothermal\" (i.e., at the same temperature from the top to the bottom). At this time the water throughout the lake is about 4\u00B0C, and, in the absence of any temperature or density differences, the lake readily mixes from top to bottom. These lakes are common in regions with temperate climates."^^ . _:b1218447 . _:b1218447 "DOI:10.1139/f83-207"^^ .
