Irrigation, Command Area Development And Flood Control

2.9.1. Water is a serious limiting factor as the State has harnessed the
available surface water potential. Of the total annual water potential of
46,540 million cubic metres (MCM) in the State, surface flows accounts for
nearly half. The total surface water potential of the State is 24,160 MCM
(853 TMC) including the contribution (7391 MCM or 261 TMC) from the
neighbouring States, viz., Kerala, Karnataka and Andhra. The total water
potential of the State including ground water is 46,540 MCM (1643
TMC).has almost been fully (more than 95%) tapped. Ground water resource
is, therefore, the only alternative source for further development. The
amount of ground water recharge is 22,380 MCM (790 TMC). The river basin
planning for optimum utilization of water resources is particularly important
for water starved Tamil Nadu State. Since a large %age of consumptive use
is through Irrigation, Irrigation water management is to be given a high
priority. This task requires a strong institutional arrangement for effective
implementation of the polices for better water management and
participatory approach, which is being strongly advocated by water experts.

lakh hectares). During the 10th Five Year Plan (2002-2007) upto 2003-
2004, an additional irrigation potential of 2323 hectares has been created.
During 2004-2005, additional irrigation potential of 7573 hectares is
expected to be created and in the year 2005-06 an irrigation potential of
5143 hectares is proposed to be created.

millimeters of rainfall a year. Per capita availability of water resources in
Tamilnadu (population about 62 million) is only 900 cubic meters a year,
compared with 2,200 cubic meters for all of India. The state’s dry season
lasts five months (January through May) even in good years, and severe
dropughts occur in 3 of 10 years, severely limiting cultivation of crops
between June and September. A recent series of droughts and water
shortages has highlighted the importance of good water resources and
irrigation management. It is with this background that the Irrigated

to facilitate interchange of information amongst WUAs through development
of websities for each WUA; (iv) re-orienting and strengthening institutions
and instruments required for effective integrated water resources
management in the State including unbundling resource management from
service delivery institutions, strengthening and expansion of Basin
Development and Management Boards; and (v) assistance in the coordinated
