Summary: Abstract: The Brazilian government is encouraging increased production in fish in large reservoirs nationals. In Furnas reservoir (MG) were proposed sixteen aquaculture parks for the installation of cages and we intend to implement a framework for monitoring water quality in these parks. Therefore it is important to know the parameters of water quality and its variation over time. This paper presents a method for classifying these aquaculture parks in function of its spectral response and multitemporal. To consider different situations in the analysis were used ten Landsat images, five in the rainy season and five in the dry season. The images were selected from the database of images from the TM sensor of Landsat 5 satellite. We used the bands 1, 2, 3 and 4, forming a database with 40 variables. In the final stage, we used the hierarchical cluster analysis by Ward method to group the parks into similar clusters.
