A dimictic lake is a body of freshwater whose difference in temperature between surface and bottom layers becomes negligible twice per year, allowing all strata of the lake's water to circulate vertically. All dimictic lakes are also considered holomictic, a category which includes all lakes which mix one or more times per year. During winter, dimictic lakes are covered by a layer of ice, creating a cold layer at the surface, a slightly warmer layer beneath the ice, and a still-warmer unfrozen bottom layer, while during summer, the same temperature-derived density differences separate the warm surface waters (the epilimnion), from the colder bottom waters (the hypolimnion). In the spring and fall, these temperature differences briefly disappear, and the body of water overturns and circulat

- Dimíctico es una calificación que se aplica a los lagos que tienen la característica que las aguas se mezclan vertical completamente dos veces al año. Los periodos de mezcla son la primavera y el otoño, cuando la temperatura de las aguas alcanza los 4 °C homogéneamente en todo el perfil vertical. Los periodos de estratificación son durante el verano, en que se produce la estratificación térmica al calentarse las aguas superficiales, y el invierno, cuando se hiela la superficie del lago y quedan más calientes las aguas profundas.

| - A dimictic lake is a body of freshwater whose difference in temperature between surface and bottom layers becomes negligible twice per year, allowing all strata of the lake's water to circulate vertically. All dimictic lakes are also considered holomictic, a category which includes all lakes which mix one or more times per year. During winter, dimictic lakes are covered by a layer of ice, creating a cold layer at the surface, a slightly warmer layer beneath the ice, and a still-warmer unfrozen bottom layer, while during summer, the same temperature-derived density differences separate the warm surface waters (the epilimnion), from the colder bottom waters (the hypolimnion). In the spring and fall, these temperature differences briefly disappear, and the body of water overturns and circulates from top to bottom. Such lakes are common in mid-latitude regions with temperate climates. (en)

Los lagos dimícticos se distribuyen por las latitudes templadas del planeta, en las cuales puede existir la helada invernal. (es)
