The present review paper deals with the assessment of water quality and source of pollution in worldâ€™s famous Dal Lake in Jammu and Kashmir (India). Dal lake receives water from four famous basins namely Hazratbal, Bod dal, Gagribal and Nageen. Literature published on Dal lake indicates that water quality parameters like BOD, electrical conductivity, nitrate, dissolved oxygen etc show spatial and monthly variations due to increase in the urbanization, unreasonable activity, lack of knowledge of local residents, inflow coming from 15 major drains of Srinagar city, plastic debris, stagnation of lake water, and other various factors. The water sample shows poor quality of water near the house boats and banks of lake as compared to open area of water body. There is a drastic change in the quality of water from the area of contamination, around house boats and open area of water body indicating heavy organic pollution to the water body from the contamination areas and habitation. Further, sudden and unexpected rise in the temperature in valley restricts the growth of various aquatic species present in the dal lake, rise in temperature may become fatal to fish growth, phytoplanktons, zooplankton etc
