ABSTRACT

Water management planning in California is conducted on local, regional, and statewide levels. Although the geographic perspective of each planning level is different, planning for all of these levels faces the same increasingly difficult issues: the pressures of a growing population on existing supplies, re-allocation of water resources to environmental uses, more stringent regulatory requirements, environmental consequences of developing new sources of supply, and the increasing costs of implementing new programs or projects. To plan for long-term water service reliability, planners must examine an increasingly wide array of supply augmentation and demand management options to find the best courses of managing the need for water service system reliability.
