From the Preface During the last few decades lakes allover the world have become the focus of environmental investigations. The increased human activities including excessive dumping of organic as well as non biodegradable wastes have brought about drastic changes in lake environment in India and especially Calcutta now Kolkata. The urban lakes in Calcutta are in fact predominantly plagued with problems pertaining to poor water quality prolific growth of weeds and loss of bio eco aesthetic values. Keeping in view of these threats to Rabindra Sarovar (RS) Government of India has declared this lake as a National Lake under the National Lake Conservation programme (NLCP). The basic objectives of such a designation to RS are to improve its environment along with prevention of pollution catchment area treatment desilting deweeding as well as research and development studies on floral and faunal activities and related ecological aspects. So as a part of the NLCP present investigations were undertaken on two major urban lake environments viz. Rabindra Sarovar and Subhas Sarovar which are located in the heart of the city Calcutta. A comprehensive study of physico chemical characteristics of water and sediment and benthic fauna was undertaken in the present research to cover a multitude of impairments of the aquatic system like presence of nutrient salts and estimation of benthic condition. Herein the physico chemical status of the lake ecosystem is described covering a wide spectrum of parameters while the study on the benthic fauna emphasized their importance as an effective tool for supplementing the physico chemical information on the lakes. Various biological indices were calculated to reflect the overall condition of the aquatic system by a single index value. On the other hand statistical analyses were done to elaborate the inter relationships between the selected abiotic factors and benthic components of the lake so that the available information may clearly and convincingly demonstrate the health of these two lakes. 120 pp. Seller Inventory # 51103
