Abstract

The district of Chileans Araucanian Lakes is a group of lakes of glacial origin that are located between 39° and 42°, Lat. S and 71° and 72° Long. W that are characterized by presenting oligotrophic conditions. The last of the chain of lakes of Valdivia Basin River is the Riñihue, a temperate monomític lake, reason why its study is of great importance, since it reflects any disturbance in the chain. It is relevant to have precise spectra of the photosynthetically active and ultraviolet radiation of the location area to calculate the photosynthetic potential in these lakes. In this paper, an assessment is made about the applicability of the COART radiative transport model in freshwater aquatic systems.
