C<strong>on</strong>certed ef<strong>for</strong>ts were also made <strong>for</strong> the <strong>development</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> minor irrigati<strong>on</strong> sector~ as<br />

well as groundwater sources under various Plans. As at the end <str<strong>on</strong>g>of</str<strong>on</strong>g> March 1980. there<br />

were 500 I minor irrigati<strong>on</strong> schemes in the state <strong>and</strong> the ayacut benefited by these<br />

schemes was 121944 ha. (net) or 142116 ha. (gross) (GOK, 1990:8).<br />

However. utilisati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> irrigati<strong>on</strong> potential created under vanous water<br />

harvesting schemes <strong>and</strong> projects In the state is neither commensurate with the<br />

quantum <str<strong>on</strong>g>of</str<strong>on</strong>g> investment made nor in terms <str<strong>on</strong>g>of</str<strong>on</strong>g> area expansi<strong>on</strong> expected in successive<br />

plan periods. It is reported that area brought under irrigati<strong>on</strong> up to 1998-99 including<br />

minor irrigati<strong>on</strong> was 4.45 lakh ha. (net) <strong>and</strong> 7.25 lakh ha. (gross) (GOK, 1999:83).<br />

The per<strong>for</strong>mance <str<strong>on</strong>g>of</str<strong>on</strong>g> major <strong>and</strong> medium irrigati<strong>on</strong> projects measured in terms <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

utilisati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> irrigati<strong>on</strong> potential created was 79 per cent in the case <str<strong>on</strong>g>of</str<strong>on</strong>g> completed<br />

schemes <strong>and</strong> <strong>on</strong>ly less than 22 per cent in respect <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>on</strong>-going <strong>on</strong>es. The overall rate<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> utilisati<strong>on</strong> is below 47 per cent (Viswanathan. 1999). Only about 10 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

the tanks identified arc under usc now. Nearly 10 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g> the wells used <strong>for</strong><br />

domestic use go dry during summer seas<strong>on</strong>. Though the groundwater potential <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />

state is 7900 Mm]. <strong>on</strong>ly 25 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g> the potential is being utilised. Thus. the<br />

overall scenario <str<strong>on</strong>g>of</str<strong>on</strong>g> per<strong>for</strong>mance <str<strong>on</strong>g>of</str<strong>on</strong>g> irrigati<strong>on</strong> sector, particularly major <strong>and</strong> medium<br />

~ The minor irrigati<strong>on</strong> schemes in the state are classified in terms <str<strong>on</strong>g>of</str<strong>on</strong>g>: a) c<strong>on</strong>structi<strong>on</strong> <strong>and</strong><br />

renovati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> irrigati<strong>on</strong> tanks: b) c<strong>on</strong>structi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> diversi<strong>on</strong> works from natural streams; c)<br />

salt water exclusi<strong>on</strong> <strong>and</strong> drainage works; reclamati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> backwaters (Kuyu/s). e)<br />

improvements to <strong>and</strong> protecti<strong>on</strong> "orks in ,treams <strong>and</strong> channels serving irrigati<strong>on</strong> <strong>and</strong><br />

drainage: <strong>and</strong> f) lift irrigati<strong>on</strong> works. The minor irrigati<strong>on</strong> works are divided into four<br />

categories. viz .• Minor Irrigati<strong>on</strong> - Class I works; Minor Irrigati<strong>on</strong> - Class II works; Lift<br />
