As the State of California is only delivering 20 percent of the water Metropolitan requested from the State Water Project this year, an Incremental Interruption and Conservation Plan has been implemented to allocate the water supplies Metropolitan has available. Under the Plan, a monthly target quantity of available water is established for each of the water agencies which Metropolitan serves. Agencies exceeding the target are assessed a surcharge and agencies using less than their target quantity are receiving a conservation incentive payment. Metropolitan's goal is to reduce water deliveries this year by 31 percent to balance water sales with available supplies. These supplies include water purchased from the Governor's 1991 Drought Emergency Water Bank and water made available by Imperial Irrigation District's implementation of water conservation projects under two Agreements between Imperial and Metropolitan. The Water Bank has been established to transfer water from areas with relatively good supplies to areas with a critical need for additional supplies due to drought. Water Bank supplies are from purchases of stored water, programs under which farmers turn to alternative groundwater supplies to irrigate crops, and agreements with farms to fallow land. Proposals which contemplate more efficient or effective use of water must be negotiated on a case-by- case basis. Technical, economic, environmental, legal, and institutional characteristics may vary.
