ABSTRACT: Lakes of urban regions contribute greatly towards ecological protected zones and true indicators for urban developmental strategies and its sustainability. Mysuru is the second biggest city in Karnataka blessed with dozens of lakes and attracts varieties of migratory birds, water fowls with lush green and being tourist destinations. The city is one of the tier II in the state and is a hub of industrial activities due to salubrious climate and availability of natural resources. Mysuru is known for its memorable annual Dasara celebrations which is an unforgettable events in the History of Karnataka. The notable waterbodies are Karanji, Kukkarahalli, Lingambudhi, Dalvoy and Devanoor lakes. Most of the streams belong to first order and few belong to second and third order. The study area portray decent greenery shelter and lakes enhances the beauty of the heritage city and also improved the groundwater table. Mysuru had over 30 lakes few decades ago, but at present only few lakes are surviving. During Maharaja’s rule of 19th century, most of the lakes were built to fulfil the purpose of water supply for domestic, industries, irrigation and other works through urban runoff and rainwater as main sources. The present study aims in the mapping of spatio-temporal detection of Mysuru lakes through manual and digital extraction of data in GIS environment. An attempt have made to analyze the changes of lakes coverage area using SoI toposheet, LISS-III, Sentinel-2A and Google Earth image by adopting Visual Image Interpretation Techniques (VIIT) through Erdas Imagine software. This study demonstrates the change detection and deterioration of lakes in Mysuru city due to human pressures and for future implementation strategies.
