Features of the Chubut River

The Chubut River is considered to be the largest river in Patagonia. It joins the provinces of Río Negro and Chubut (see Río Lobos).

It has a very pronounced pluviometric gradient in its headwaters.

It is worth mentioning that in only 40 linear kilometres the annual rainfall goes from 1200 mm to 200 mm (see Paiva River).

Another peculiarity is the lack of lakes in the area where its headwaters are located.

This makes it more sensitive to rainfall. Irregular in shape, with significant thermal variations.

With low water levels, which are even more pronounced in the dry season, i.e. summer. This means that the Chubut River has 4.5 times more water in November than in February.

In spite of all the vicissitudes that the Chubut River has to endure, it is possible to compensate for them with the wonderful abundance of vegetation on its banks. With the obvious contribution of nourishment in the sections with clear water (see Cabriel River).
