摘要：The lakes in a general way, play an important role for the man, not only for representing source of water resources, but, also for function as data bases on the different paleoenvironments and paleoclimates that had characterized the planet during the Pleistocene and Holoceno periods. The lake’s formation depends basically of a depression occurrence in the surface of the Land and of a favorable water balance. These depressions can originate through some processes, such as tectonic, volcanic, glacial, aeolian, fluviatile among others. In Brazil the lakes are generally formed for fluviatile processes, due to high hydrodynamics of medium and large rivers. However, others types of lakes can be found throughout its territory. The study of the Brazilian lakes has provided information about the limnological characteristics, paleoenvironmental conditions, cycle of carbon, dynamics of floodings and of the nutrients among others, contributing for increase of knowledge regional. In this direction, the present work consists of a brief survey of the main studies developed in lacustrine environments in Brazil, aiming to orient the persons that desire to study this so interesting and current subject, and at the same time so important for continuity of the biological diversity
