Abstract
 Statistical methods are used to study the concentration variations for the heavy metals, Fe, Mn, Cu,
Zn, Pb, Cd, Cr, Co and Ni at all stations in the different seasons. Higher values are recorded at the stations, which
receive drain water. Organic matter, carbonate, phosphate, calcium, magnesium, and heavy metals were analyzed in
sediment. The organic matter contents are of irregular trend affected by both agriculture and domestic effluents. The
carbonate percent is increased in spring as a result of increasing photosynthesis. The phosphorous concentrations are
affected by the sources of drain, agriculture effluents, phosphate fertilizers and organic matter precipitated in the
surface sediment. Zinc and iron are of high concentrations in spring and autumn. Manganese concentrations show its
maximum in spring and its minimum in winter. High content of copper is in summer and spring near drain. Cobalt is
precipitated as cobalt carbonate as a result of Lake water alkalinity. The distribution of lead concentration is of
irregular trend. The average cadmium concentration due to drain water is of high level. The high content of Cr was
recorded in spring. The behavior of chromium and nickel was explained through their adsorption on iron and
manganese oxides surfaces.
