Pehoé Lake is a surface water body located in Torres del Paine National Park, in the Magallanes Region of southern Chile. The lake is fed mainly by the Paine River through the Nordenskjöld Lake, but it also receives the water from the outlet of Skottsberg Lake.

Pehoé Lake was formed during the last glacial period, which ended about 10,000 years ago. During this time, glaciers carved out the deep valley in which the lake now sits. As the glaciers retreated, they left behind a natural basin that filled with water, forming the lake.  The lake is fed by a number of glacial rivers and streams, which is why its water is so clear and cold. The lake's turquoise color is due to the presence of rock flour, which is a fine powder of rock that is produced by glacial erosion.

Pehoé Lake is a closed-basin lake, meaning that it has no outlet. This means that the water in the lake is constantly evaporating, and the minerals in the water are left behind. Over time, this has resulted in the formation of tufa deposits, which are strange, lumpy structures that can be seen around the edge of the lake.

The island in Pehoé Lake is called Magdalena Island. It is a small island located in the center of the lake, and it is home to a colony of Magellanic penguins. The Magellanic penguins on Magdalena Island are the third-largest penguin species in the world. They are known for their black and white plumage and their yellow crests. The penguins typically arrive on the island in September and stay until April. During this time, they mate, lay their eggs, and raise their young. The island is also a popular nesting ground for other birds, including ducks, geese, and flamingos.

Pehoé Lake is a beautiful and unique place, and it is a popular tourist destination for people from all over the world. The lake's stunning scenery and abundant wildlife make it a truly unforgettable place to visit.
