Viewed from this perspective, such investments are a cost-effective component of water supply planning. 2. Short-Term Demand Forecasting and Management Another information-related aspect of systems integration is improved forecasting and management of short-term water demand by agriculture and cities. Changes in soil moisture, local and regional rainstorm events, changes in temperature and operations of competing water diversions can all affect stream flow conditions and the diversion needs and opportunities of an individual water user. The ability to anticipate and react to these variables can result in a reduction of unnecessary diversions and reservoir releases, allowing for more efficient overall use of water. Rainstorm awareness programs, irrigation planning information based on localized climate and soil moisture data and irrigation demand scheduling are all important aspects of short-term demand management that could significantly increase the ability of existing water supply systems to meet additional needs. Issues To Be Addressed Funding for many of these programs is dependent upon the actions of the state legislature. Strong support from a variety of local municipal and agricultural interests throughout the state will be required. Operation and planning of water supply projects and administration of water rights has traditionally been a local activity. The development of a sophisticated information system for improved water management on a larger scale may be viewed with suspicion by local interests. Such a system must therefore be accessible and easily understandable to all water users and interest members of the public. III. POLITICAL SOLUTIONS (to be addressed by Kaplan et a1)
