West Bengal receives sustained rainfall due to its proximity to the Bay of
Bengal yet we are unable to make full use of it due to some natural constraints. Rapid rise in demand of water in all sectors
of domestic, industrial and agricultural uses during the last decade has started throwing up several problems in water
resources management. So the optimal management of available Water Resources has become a major issues world over. Due to
occurrence of recurrent droughts, advent of high yielding varieties and introduction of an incentive oriented agricultural
pricing policy paved the way for irrigated agriculture. The Spatial and temporal variability of rainfall along high
evapo-transpiration and runoff is posing a major challenge to the scientific community. As a result development of agriculture
is essentially dependent on irrigation, not only in Rabi / Boro season but also in Khariff seasons in the event of drought or
inadequate rainfall. Harnessing of Water Resources to meet various Sectoral requirements has been our prime concern, which is
the foundation of our agricultural vis-à-vis economic growth and welfare of state. Water Resources are being utilized in the
State from medium and major sized irrigation schemes whose culturable command area(C.C.A) above 2000 ha. and from minor
irrigation schemes with the C.C.A up to 2000 ha. as per the criteria laid down by the Planning Commission, Govt of India.
Thus small and marginal farmers who constitute the majority of cultivators and
cultivate major portion of agricultural land in West Bengal, can afford to individually invest on creation of irrigation
sources. Therefore, with a view to boosting up agriculture production in a large scale and to promote rural economy, the policy
of the government has been to create new sources and hand them over to the Beneficiary Committees through the Panchayat for
their operation, maintenance, optimal use and overall management.
Water Resources Development Directorate is responsible for the development of
existing potential of water resources available in the State through construction and maintenance of various types of MI schemes
utilizing ground water as well as surface water resources.The schemes which are implemented by this directorate for development
of water resources under M.I. sector may be categorized as below :-
Surface water resources are being utilized through irrigation tanks, storage, permanent and temporary diversions. Water of these detention storage reservoirs & Perennial sources are utilized for irrigation during the period of no rain. A small portion of surface water run off of each watershed is being utilized yet.
