Abstract: In the present study a synthesis of our researches on the main physico-chemical and biological parameters of the Cuejdel lake’s ecosystem was made, representing the variation limits of these parameters during the years 2006-2016, and in 2016 complex investigations have developed, which have highlighted the evolution and specificity of this aquatic basin. In this study, classical methods, supplemented with original techniques: scientific documentation, periodic movement in the field and sampling from established stations (queue, center and dam, from tributaries and downstream of the lake) were applied. The purpose of investigations over ten years was to determine the degree of trophicity for the studied lake and the degree of eutrophication of its water.
