Apart from these major rivers, the state also has perennial rivers and many more seasonal streams. Yet Chattisgarh is frequently plagued by droughts. Neglect of traditional water conservation practices is considered a major cause of these droughts. The key uses of water in the state include irrigation, drinking or domestic purpose, industry, and power plants.
