Water is a prime natural resource which we cannot grow or create like other natural products. Due to global warming, variation in climatic conditions and intensity of rainfall, a considerable change in the availability of water resources has been observed in different regions of our State. The availability and distribution of water resources is also somewhat uneven in different regions and sub-regions of the State. There are absolutely no two opinions about the vital importance of water, for sustenance of human, animal and aquatic lives, maintaining ecological balance and for economic and development activities for all kinds. Ensuring optimal, economical, equitable and sustainable use of water resources has become a matter of great public importance.
