This paper contains a compilation of the average values of 24 geographical, physical, chemical, biological and productivity parameters collected and processed during 12 years of research on 9 freshwaters and salmastricol lakes situated on the Romanian seaside of the Black Sea. The paper emphasizes the discussion of those parameters indicating the current degree of eutrophication of these lakes. It shows that the lakes situated in the southern part of the Romanian seaside (Limanu, Valea Arsa and Hagieni) are the least affected by the process of eutrophication; they are followed by the northern lakes (Razim and Sinoie) which are supplied with the waters of the Danube river, after these have been filtered in the floodable areas of the Danube Delta. The process of eutrophication is found to be stronger in the waters close to the agricultural areas and the urban localities from the Romanian seaside of the Black Sea.
Key words: lakes / eutrophication / primary production / water quality
