This is one of the most iconic bodies of water in the Andes, it is located about 3800 meters above sea level and is specifically located between the territories of Peru and Bolivia. Its extension is approximately 8500 km2 with a depth that exceeds 250 meters, Lake Titicaca is considered the highest and can be navigated all over the world, in Peru it is considered one of its natural heritages, in it are also a series of islands, which are Amantaní, Taquiles and Uros, which until now have managed to preserve their customs and traditions since pre-colonization.
According to experts, this lake is the product of the displacement of the tectonic plates, which gave rise to the elevation of the territory that today makes up the Andes, as well as the Collao Plateau, its characteristic climate is semi-arid which makes the action of the drainage does not have major consequences in the lake.
At present, Titicaca is just a vestige of an immense lake, which has been decreasing to what it is today, over the centuries, this lake has been part of different modifications in its structure, experts say that since Its births have experienced much lower levels than the current ones and in ancient times the water it contained was salty, it was not until a little less than 4 thousand years ago that the water suffered alterations and became sweet. In the last two millennia the lake was acquiring its current shape, in addition to the formation of its source which is called Desaguadero.
The water it contains is characterized by being crystalline and somewhat brackish, its salinity levels range between 5 and 5.5 parts of 1000, in addition it is important to note that its water has been the center of various investigations with different objectives. At present some of its points are contaminated thanks to the sewage drains, which are not treated in the correct way.
