Extending the utility of an existing water supply in any river basin suggests a management-planning approach under three general guiding principles: (1) minimize depletions wherever possible (thereby maintaining a greater manageable quantity with subsequent potential to satisfy more uses); (2) generally preserve, protect, and improve water quality (thereby retaining its itility for use by a wider variety of potential users); and (3) make carefully considered allocations (thereby assuring multiples duty, more optimal sequencing, and shifts in use to conform to current and projected soil preferences). There are many technological and managerial techniques that can be employed to implement these principles. Similarly, there are many economic, political, legal, educations, and social mechanisms that can aid or deter in achieving technologically possible efficiencies. This report examines the concept of extending utility of water in a given hydrologic complex; considers the conditions for achieving greater utility in both a physical and socio-economic sense; and discusses some of the things that might lead to better utilization from a regional or public perspective.
