The water was taken from three different sites of the lake in July, October, January and April (in four different seasons) and analysis of phsico-chemical parameters and copper and zinc ions content of the lake water were done. When physical and chemical parameters compared with the previous studies, it is found that most of these parameters were higher than the recommended standards and this affect the biota in the studied area and form a public health problem. http://pubs.sciepub.com/wjce/2/3/3/wjce-2-3-3.pdf heavy metals Lake Chemo
