Abstract: Keenjhar Lake is one of the largest fresh water lakes in Pakistan which is present in Thatta district, Sindh. It is the main source of drinking water supply for Karachi city. The present study was carried out to assess the depth controlled variation pattern of physicochemical components of Keenjhar lake water. For this purpose, water samples were collected at three depth interval (1. Surface 2.Depth of 30 m 3.Near bottom). Studied parameters include physical character (color, odor, taste, temperature, pH, electrical conductivity, hardness, oxidation reduction potential) major chemistry (Na, K, Ca, Mg, HCO3, SO4, Cl, NO3) and minor/trace elements (Fe, Cr, Co, Mn, Cu, Ni and Zn). Data reveal that there is no significant variation in the physical parameters and chemical components with depth change. All parameters in lake water are in compliance with the guideline values of WHO set for drinking water. The lake water is suitable for the survival and sustenance of aquatic life.

Key words: Keenjhar Lake, physicochemical parameters, depth variation, distribution pattern
