As Fig. 7 shows, the Sardar Sarovar Project was designed to spread surplus surface waters over north Gujarat, Kutch and Saurashtra to use surface irrigation to crowd out groundwater pumping and to accelerate groundwater recharge. Moreover, at the turn of the millennium, Government of Gujarat also invested US$150 million in 334-km-long Sujalam Sufalam spreading canal (Fig. 8) whose objective was to transfer surplus flood waters from Kadana reservoir in south-eastern Gujarat to fill up 21 rivers and streams, and several large and medium-sized reservoirs in north Gujarat, while recharging the aquifers en route. Now, the chief minister has announced a new ambitious US$1.7 billion scheme to lift to a head of 20 m a million acre feet (1.23 BCM) of Narmada water every year to fill up all dams in groundwater-depleted Saurashtra through a network of pipelines to both recharge parched aquifers and to ease pressure on groundwater (Khanna 2013). All these suggest that politicians and administrators took a more integrated view of surface-groundwater-energy co-management, while the dominant thinking in our Taskforce was limited and water-centric, focussed as it was on confining MAR to average annual non-committed surplus runoff after providing for ‘existing, under-construction and planned future’ surface structures.
