Water, nitrogen and phosphorous budgets of Lake Manzalah have been calculated using data collected from January-December 2012. The main positive contributor in the water budget of Lake Manzalah during this period was the drainage water being 6692.6× 106 m3/yr. The annual rainfall was 26.53×106 m3/yr and the evaporation 1075.6×106 m3/yr. The net annual amount of outflowing water from Lake Manzalah to the Mediterranean Sea was 9503.23× 106 m3/yr and the net amount of seawater invading the Lake estimated is 3895.76× 106 m3/yr Accordingly, the net water exchange between Lake Manzalah and the Mediterranean Sea was 5607.47× 106 m3/yr seaward negatively affects the water budget of the lake.

    The nutrient salt load of the nitrogen load in the lake from the drainage water is estimated to be 1381.09 tonnes per year and that from the rain 3.703 tonnes per year. The amount of nitrogen load transported to the sea through Boughaz El-Gamil is around 1025.753 tonnes per year; while the inflowing nitrogen load is estimated to be 180.147 tonnes per year The phosphorus load from the drainage water is estimated to be 2212.67 tonnes per year and that from the rain 8.546 tonnes per year. The amount of phosphorus load transported to the sea through Boughaz El-Gamil is 680.668 tonnes per year while the inflowing phosphorous load is estimated to be 101.687 tonnes per year.
