Lake Enol

Emerald green in colour, darker in summer than in winter, its depth allows for thermal stratification of the water during the summer and part of the autumn, forming three layers in the mass of water with a temperature that descends from the outer layer to the deep one and whose density increases from one layer to another, preventing the waters from mixing. In late autumn, the thermal stratification disappears and the waters of the three layers mix.

Plant life

In Lake Enol there is a small number of carophytes on the shore, hardly any emergent plants grow and in the area above the shore there is very little wet ground vegetation.

Wildlife

The lakes of Covadonga have been successively repopulated with fish, of which there are still some specimens of tench (Tinca tinca), crayfish (Austropotamobius pallipes phoxinus), trout (Salmo trutta fario) and crayfish (Phoxinus phoxinus).

The fish introduced into the Lakes feed mainly on aquatic invertebrates, especially larvae of dragonflies (odonates), friganeans (trichoptera), small crustaceans and beetles (coleoptera), although the trout also feed on piscivores, which in turn are their competitors.
