Romanticism and recklessness is still evident in water policy, but it is now revealed in different ways. The sequence of decisions in the expansion phase of irrigation determines today’s starting point for analysis. Environmental considerations now loom large. Expansion of irrigation for over a century has resulted in a vastly modified river system. There are flow-related and non-flow-related environmental consequences (Hillman, 2008). There are also economic consequences, in that extraction of so much water from regulated rivers reduces the reliability of irrigation allocations. Damage to water quality challenges the economic prospects of irrigation while also imposing costs on domestic and industrial water users. More than that, today’s population is increasingly concerned with appreciation and enjoyment of the multifaceted riverine environment along with the amenity of regulated rivers and streams.
