Abstract: The city of Srinagar-the summer capital of Union Territory of Jammu & Kashmir, is bestowed with a large number of picturesque lakes and serene wetlands. Among these, the Dal and Nigeen lakes have been important tourist destinations. Lakes are not only of economic value but are also ecological and environmental resources. However, these lakes are facing challenges due to climatic and anthropogenic activities. As these changes are slow and take long time, the damage goes unnoticed. Hence, long historic data provided such as of remote sensors are concrete evidence of change, which help us to understand the cause and prevent further change to some extent. In the present study, geospatial tools were employed for quantifying changes in the spatial extent of famous Dal and Nigeen lakes. In this study, Linear Imaging Self Scanning Sensor (LISS) images of 10 years gap (2007-2017), were used to detect the changes in the Dal and Nigeen lake. The results of the study show that the area of lakes has shrunken but at the same time volume retention capacities of these water bodies has increased due to dredging. The loss in the spatial extent of these lakes has in fact affected the micro-climate of the city besides exposing it to flood threat. It is estimated from the study that there is shrinkage of about 0.64 % and 1.38 % in Dal and Nigeen Lake respectively, volume retention capacity of Dal Lake has increased by 18.9 % and that of Nigeen lake by 7.12 % and mean depth of Dal Lake has increased by 82.9 % and that of Nigeen Lake by 12.8 % from 2007-2017.
