IRRIGATION IN KARNATAKA

GEOGRAPHICAL AREA:

The Karnataka State is the eighth largest State in the country and is located in the Deccan plateau.   The geographical area of Karnataka is 1,91,791 sq.km accounting for 5.83% of the total area of the Country.   

PHYSIOGRAPHY:

         The general elevation in the state varies between 450 to 900 mts. above mean sea level.  The important peaks in the state are Mullayyanagiri  (1913 mts.) in the Baba Budan Hill ranges and Kudremukh (1981mts.).  The important hill ranges are the Westren Ghats, Baba Budan Ranges and Chitradurga Hills.

IRRIGATION DEVELOPMENT IN KARNATAKA :                        

 Agriculture being the main occupation of the state, Irrigation place utmost significant part in obtaining increased yields from the land.  The development of Irrigation in the state was slow and unsystematic during the pre independence era. However, there were some notable Irrigation works undertaken and completed during the pre-independence, such as Krishnaraja Sagar (which was the only major project completed prior to independence), Vijayanagar canals, Cauvery anicut Channels, Gokak canal, Vanivilasa Sagar, Markonahalli and Anjanapura.  Though major projects like Tungabhadra, Bhadra and Ghataprabha stage-I were commenced prior to the plan period, their progress was slow and they got impetus only after their inclusion in the first five year plan.

           There were more than 25,000 tanks scattered over erstwhile Mysore state. But in Bombay Karnataka and Hyderabad Karnataka areas, the number of such minor irrigation works are meager.

ACHIEVEMENTS UPTO THE END OF MARCH 2016 :

             The total investment up-to the end of March 2016 on Irrigation in the state is  Rs.51957.58 crores on major & medium irrigation (using surface waters).

             Up-to the end of March 2016 a total irrigation potential is 28.68 lakh ha. (Major & Medium Irrigation projects).

 

FINANCIAL AND PHYSICAL PROGRAMME FOR 2015-2016:

          During 2015-2016 , Rs. 1151541 lakhs has been allocated for major & medium irrigation projects. It is programmed to create potential of 75576 ha.
