Lake Burullus is located in the far north of the Nile Delta between the two branches of Damietta and Rosetta, directly on the coast of the Mediterranean Sea. The lake exposed to many environmental influences that have led to significant changes in the properties of water. The main objective of the current investigation was to provide a snapshot of water quality in the lake. Water sampling was carried out seasonally from six stations covering the three sectors of the lake. Physicochemical parameters were studied; water temperature, transparency, depth, salinity, total alkalinity, PH, DO, BOD and COD. The results of previous measurements have been found within the suitable range for freshwater fish species. According to the annual concentration values, the examined heavy metals were in the order; Zn> Cu>Pb> Cd> Ni, constituting about 12.33, 5.42, 4.97, 4.75 and 3.73µg/l, respectively.
