%X This paper presents the results of the mapping of the changes in land use and land cover of the Cambutu River watershed, in Rio Grande do Sul, Brazil, in the last 11 years, using images of Landsat Data Continuity Mission (LDCM). We used images of Landsat 7 and Landsat 8, in 2003 and 2014, respectively. Five classes of LULC were defined for supervised classification: water, grassland, agriculture, forest and reforestation. The method used for the classification was the MaxVer. To facilitate the visual identification of the different types of LULC in the training stage, we performed five work trips to the study area. Findings show that in the Cambutu River watershed the predominant class in 2003 was grassland that occupied 84.57% of the watershed area in 2003 and decreased about 38.67% in the study period. The agricultural area increased, occupying 4.14% of the watershed in 2003 and 11.34 in 2014. The forest area decreased 25.87% and the reforestation area decreased 26.11% in this period. Based on this quantifications, we can verify that there was an increase in the in the agriculture areas, that occupied areas previously occupied by grassland, forest and reforestation. The growth of agricultural areas was, for the most part, increase soybean cultivation in the Cambutu River watershed.
