Abstract: Lake Kolleru is the largest fresh water lake in India is located in between twin deltas of Krishna and Godavari in West Godavari and Krishna districts of Andhra Pradesh and lies between the two mighty rivers, the Godavari and Krishna. It is an extremely shallow depression formed in between the two deltas due to fluvial and marine activities. The kolleru lake and its surroundings have been subjected to human induced degradation due to mismanagement of land and water resources particularly with the introduction of intensive agricultural and aquaculture activities. The striking manifestation of this phenomenon is seen in various kinds of hazards such as flooding of foreshore areas of the lake, back water intrusion, ground water pollution, coastal morphological changes, etc. The present study is mainly focused on the present status of various parameters related to land and water resources of the lake Kolleru and the adjoining fragile coastal geo-environment using spatial information techniques. The study includes the generation of updated spatial information on land and water resources that cover rainfall, lithology and structure, geomorphology, drainage and surface water bodies, Land use / land cover and also transport network and settlements. The integrated analysis of these parameters has helped in thoroughly addressing the perennial issues like flooding of foreshore areas of the lake, intrusion of back water in Upputeru and its tributaries, adverse effects near Upputeru river mouth etc and the need for suitable land and water management measures.
