Water is a unique resource because it is essential for all life and it constantly cycles between the land and the atmosphere. Water resources are of great environmental issues and studied by a wide range of specialists including hydrologists, engineers, ecologists, geologists and geo morphologists (Kumar and Dua 2009). It has become an important issue for them as it affects not only human uses but also plant and animal life. Lakes are one of the most potential water resources that can meet the increasing demand of water throughout the Dhaka city in dry seasons. Humans frequently depend on lakes for a great many services such as drinking water, waste removal, fisheries, agricultural irrigation, industrial activity and recreation. For the reason lakes have become important ecosystems (Hameed M. et al. 2010). Water quality is deteriorated day by day due to numerous biological, physical and chemical variables causing water toxicity. When concentration of any element or compound exceeds the tolerance limit for organisms that element is treated as pollutants. Research work has been carried out to determine some vital water quality parameters those abate the water quality and find out the most vulnerable location of Dhanmondi, Ramna and Hatirjheel lake.
