This document discusses the conservation, restoration, and management of lakes. It begins by outlining the objectives and importance of lakes for ecosystems and human habitats. Several causes of lake depletion are then described, including inadequate rainfall, industrial wastes, borewell digging, and unplanned urbanization. The document then examines case studies of specific lakes in India, including analyses of water quality, public surveys, and restoration strategies. It concludes by stressing the toll that urbanization and pollution have taken on lakes and the need for immediate action to restore them.
