The lake Fetzara is 18 km from Annaba, it was officially classified as a wetland protected by the Ramsar Convention (2003). The waters of the lake and soils are affected by salinization. This study objective is to determine the physico-chemical characteristics and the classification of the Fetzara lake’s water (North-eastern Algeria) by using the characteristic reports of major elements, Piper diagram, the analysis of the matrix of correlation, the ascendant hierarchic classification ( AHC) and the principal component analysis (PCA). The results allow us to classify statistically the Fetzara lake’s water into 4 distinct groups: the first group of high salinity are waters of the South- East region of the lake, the second one of an excessive salinity situated in the center of the lake, the third one of average salinity characterize the North-East of the lake and the last one of sulfate waters of high salinity in the south of the fetzara lake.
