由于加利福尼亚州今年仅提供州水项目要求的20%的水资源，已实施了一项增量中断和保护计划，以分配大都会可用的水资源。根据该计划，Metropolitan服务的每个供水机构都将制定每月的可用水量目标。超过目标的机构将被征收附加费，使用低于目标数量的机构将获得保护奖励金。大都会今年的目标是减少31%的供水量，以平衡水销售和可用供应。这些供水包括1991年从州长的干旱应急供水银行购买的水，以及帝国灌溉区根据帝国和大都会之间的两项协议实施节水项目所提供的水。 已经建立了水库，将水从供水相对较好的地区输送到因干旱而急需额外供水的地区。水库供应来自购买储存的水、农民转向替代地下水供应灌溉作物的项目，以及与农场签订的休耕土地协议。考虑更高效或更有效地使用水的提案必须在个案基础上进行谈判。技术、经济、环境、法律和制度特征可能会有所不同。

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.
