with the States which face scarcity of water; and
(d) if so, the details thereof?

(a) to (d) As the river basin/sub-basin are natural
hydrological units, Water balance studies, to identify whether a
particular river basin/sub-basin is surplus or deficit in water,
are carried at basin/sub-basin level. Ministry of Water
Resources/Central Water Commission has prepared a National
Perspective Plan (NPP) during 1980. Water balance studies for
the basins/sub-basins/at diversion points have been carried out
for Peninsular and Himalayan Components of NPP. Water balance
studies of 137 basins/sub-basins and at 52 diversion points have
been conducted under Peninsular Component while water balance
studies at 19 diversion points have been conducted under
Himalayan Component. Based on these water balance studies,
interbasin water transfer proposals for surplus to deficit
basins have been proposed. 30 water transfer links, 16 under
Peninsular Component and 14 under Himalayan Component have been
identified for preparation of feasibility reports. National
Water Development Agency completed feasibility reports of 8 link
projects.
