		<abstract>Acknowledging the benefits of it, as well as the motives and the consequences of the increase of the water bodies, the present paper aims to specialize this growth in the municipality of Formigueiro, State of Rio Grande do Sul. We used tools made available by imaging processing and GIS software, such as ERDAS IMAGINE 2013 and ARCGIS 10.2, and we applied a decision-tree classification approach, that consists in divide the water bodies of 1995, 2005 e 2015 by its values of electromagnetic reflectance. In the year of 1995, we recognized 586 surface water bodies, wherein 14 of this amount ad measures above 20 ha, in 2005 we observed an increase of 40 surface water bodies, resulting 625 with just 11 of them above 20 ha, this increment remains in 2015, reaching 703 surface water bodies with 14 above 20 ha. This quantification expressed in units of measurement reveals a peculiar data about the logic of its growth, since in 1995 there were 1778,13 ha or 35,83% occupied by dams, however, in 2005, despite the growth of the dams, its territorial occupation presented a decrease of 144,99 ha where we quantified 1761,68 ha, 32,73%, that in the year of 2015 had again an increase, totaling 1939,05 ha occupied, or 38,87% of the municipal territory. In summary, projects in this research line are relevant for identification and quantification of water bodies studies, as well as studies referring grants for artificial reservoirs.</abstract>
