TR(BR)-12/99-2000 : Water balance of Sagar lake

Abstract

Lakes play an important role in shaping the hydrological, ecological and environmental balance of the region by developing flora, fauna and habitation of aquatic biota. Like other lakes of the world, Sagar lake is also facing manifold problems of siltation and deterioration of water quality, thus, threatening the survival of the lake.

Previously most of the scientific studies carried out on the Sagar lake have focused on the physico-chemical properties of the lake water and the possible inter-relationship and interaction between their properties and biological factors like plankton, macrophytes, macrofauna, etc. Therefore, to understand various hydrological processes of the lake, water balance study has been carried out.

The present study has been carried out for the quantification of various water balance components like inputs and outputs and thus to visualise the influence of these parameters on the storage changes.

The outcome of the study will be very much helpful in proper management of the lake water and in conducting other relevant hydrological studies leading to conservation of the valuable lake water for the community.
