Lake Burullus is one of the northern Delta lakes, connected with the Mediterranean Sea through El-Boughaz opening. The main objective of the present work is to study the physical and chemical properties of the lake and its relation with the phytoplankton communities, chlorophyll-a as well as diversity and Eutrophication index. The studies revealed that, the pH values lie in alkaline side, with wide range of fluctuation (7.15–8.5), the total suspended matter was relatively high (18.2–149 mg l−1), high values of dissolved oxygen (5.17–11.29 ml l−1) and high concentration of nutrient salts, (nitrate ranged between (3.4–44.7 μmole l−1), nitrite (0.42–15.95 μmole l−1), ammonia (1.46–50.60 μmole l−1), phosphate (0.63–14.83 μmole l−1), and silicate (6.54 to 119.3 μmole l−1). Chlorophyll-a concentration showed a wide range of fluctuation (13.8–127.4 μg/l) and the highest value were recorded at the western region of the lake. Phytoplankton counts showed a pronounced increase (1.9 × 106 units l−1) as compared with previous studies, a total of 170 species were identified represented mainly by Bacillariophyceae (44.8% to the total community) comprising 68 species, Chlorophyceae (39.99%) 54 species, followed by Cyanobacteria (9.52%) 26 species, Euglenophyceae (5.63%) 15 species. Phytoplankton standing crop attained the highest counts at the western sector particularly at station X during spring and summer (6.7×106 and 4.1×106 units l−1 respectively) due to the dominance of Bacillariohycean species Stephanodiscus phytoplankton diversity was high and showed widely range (1.47–3.66 nats). A series of stepwise regression equations describing the dependence of phytoplankton standing crop, its main groups and diversity index on the changes of the most biotic prevailing conditions were given and discussed. In general, the results showed that the Lake is considered as a eutrophic area. This phenomenon observed in the body of the lake water that receives large influxes of nutrients, which reflects high phytoplankton counts, diversity index and Chlorophyll-a
