Incentives, technical assistance and further R&D needed. Where geologically and hydrologically feasible in all states. Further informa- . tion on hydrology and geology is needed. All portions of Ogallala dewatered of gravitational water. Further research and technology development is needed. All portions of the Ogallala where mar- ginal lands unsuitable for irrigation development occur. Significant institu- tional changes would be needed. Opportunities in all states to reduce ET losses from both cu 1 t i vated and non- cultivated areas. The General Contractor has determined that the potential for significant augmentation of local water supplies within the Study area and within the selected Study period is limited and not readily quantifiable. Available data concerning most of the augmentation potentials and their future feasi- bilities are very limited. Analyses for Strategy Three, therefore, were made by the General Contractor as a separable strategy and examined qualitatively where local physical conditions offer possibilities for subregional augmen- tation. This strategy was not subjected to the rigorous impact analysis and 5
