(b) Regulating and damming of rivers affects their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir, resulting in rockier stream beds and poorer habitats for the river's aquatic life. (c) In Gujarat, the Sabarmati basin farmers were agitated, and almost caused a riot over the higher priority given to water supply in urban areas, particularly during droughts. (d) Today, in Western Rajasthan, the practice of rooftop rainwater harvesting is on the decline as plenty of water is available due to the perennial Rajasthan canal, though some houses still maintain the tanks since they do not like the taste of tap water.
