  • Irrigation reservoirs and canals are widely used for drinking water supply now.
  • Minor irrigation schemes being carried out throughout the state includes
    •  Lift Irrigation Schemes,
    • improvement of existing lakes and ponds, diversion schemes for natural streams,
    • prevention of salinity intrusion in rivers, drainage works to paddy fields,
