The accumulation lake Sânandrei was founded in 1971, on the course of the brook Valea Lacului, at an altitude of 117 m, on a surface of 50 ha. At present, the lake is leased to a trading company, which exploits it for fishing and recreation. Our research (performed in the period 2004 – 2007) consisted of several trips in the lake area, in various periods, in order to better render the structure of the phytocoenoses. The data processing implied identifying the vegetal associations, following the centralization and analysis of the samples of vegetation collected on the field, drawing up the summary of the cenoetaxonomic units and the analysis of the vegetal associations, having several viewpoints in mind. The study is based upon the principles of the Central-European floristic phyto-coenologic school. There have been identified and analyzed 13 vegetal associations, in accordance with the mentions above.
