  • Plant life

    Among other animals, there are bryozoans (Plummatella repens), molluscs (bivalve Planorbis and gastropod), leeches (Erpobdella monostriata and Dina lineata), oligochaetes, heteroptera (Micronecta poweri), ​​flies, beetles, mayflies, amphibians like the brown frog and the common toad (Rana temporaria and Bufo bufo), brown trout and minnow.

    Wildlife

    Small charophyte algae, up to 15 cm in length, are distributed below 2 m in depth, preferably between 2 and 12 m, being scant down to 15 m in depth.

    The angiosperm found deeper down is filiform pondweed (Potamogeton). There are also floating leaf plants: Potamogeton natans, which is rare, and Ranunculus peltatus, as well as emergent plants such as Eleocharis palustris, which prefer shallow waters.

    Finally, the zone of rapid desiccation, besides being partially occupied by some of the above plants and others that use the resources of aquatic and terrestrial habitats, such as Rorippa, Lythrum, etc., also has willows and plants which invade dried basins such as Herniaria, Filaginella, etc. In any case, there is scant plant covering on the eulittoral zone or foreshore.

The original lake, which occupied the depression at the foot of the mountain cirque, had a depth of about 15 m and a kidney-shaped outline. In its current state, after the increase in the volume of water it contains as a result of works carried out to exploit this water, Lake El Valle has the greatest surface area of all the lakes in the region. What's more, due to its unique location, it is among the most prized for its natural attractions.

The lake is emerald green in colour. Before the reservoir was built, it was bluer than today. Its waters are colourless and transparent, presenting summer thermal stratification.

Livestock approach its banks and cattle enter the shallower water to cool off, preferably at the small mound separating the two dams, where there is more amphibious vegetation.
