The lake Provala near Vajska (Serbia, Yugoslavia) was created by the embankment performation during high Danube river levels in 1924. It is a very important water ecosystem of natural origin, which is a fact of great importance for exact biological and ecological research. Miljanovic (1996) and Pujin (1997) present the first lake Provala water state data. They emphasise the reinforced eutrophication process in the shore region. This paper presents the review of the macrophytes vegetation of the lake Provala recent state for the first time, with special attention to dominant plant species. Based on the present taxons analysis, as well as water chemical parameters analysed (NH4(+), NO3(-), NO2(-), PO4(3-), HPK, BPK, pH), it can be concluded that the eutrophication process is present in this water micro-reservoir. It is especially true for the shore region and shallow waters, where the process is already well under way and very fast. These research results can be used to efficiently protect this natural water ecosystem.
