From this lake you can appreciate the views of the top of Pica Palomera, at 2460 meters high. Due to mining activity, both the pond and the surroundings were affected. Today, the water has a much more acidic pH than most of the lakes in the Pyrenees, which does not allow the survival of aquatic vegetation or vertebrate animals.

This dam has different names: its official name is barratge deth Hons dera Coma, in Aranese. However, there are those who refer to it as the barratge de Barrier or simply the Sant Joan Toran dam. It is not very well known, but it is located in the heart of the Torán valley and very close to the Liat mines. Depending on the flow of the Gòrges d'Ermèr river, the water takes on different shades. If the level is low, you can see a reddish tone that brings closer to the mining past of the area. If, on the other hand, the level is high, the water takes on a turquoise tone that blends with the green of the vegetation.
