History

In the early Islamic period, the port of Burullus was situated near the mouth of the lake (the place where it was connected to the sea through a small opening). Burullus port functioned as one of the defensive frontier settlements of the Nile Delta coast. An island settlement within the lake called Nastaru lent its name to the lake as a whole. Canals connected the lake to the Rosetta branch of the Nile. At this time the lake was growing and expanding southwards as a result of changes in

. Agriculture drainage water accounts for 97% of the total inflow to the lake (3.9 billion m3 per year), followed by rain water (2%) and groundwater (1%). 16% of the lake's water evaporates and 84% flows to the sea.

Wildlife

According to a Biodiversity Report of the Egyptian Environmental Affairs Agency 33 species of fish, 23 species of reptiles, 112 species of birds, and 18 species of mammals live in and around the lake. Fish species declined from 52 recorded at the beginning of the 20th century, mostly due to the inflow of agricultural drainage into the lake resulting in lower salinity.Egyptian Environmental Affairs Agenc
