Drought

Weather Extremes Threaten Our Water Resources

保护必须继续成为一种生活方式

在经历了史上最干旱的三年之后, heavy precipitation this winter has boosted California’s snowpack to healthy levels and are helping replenish our depleted reservoirs and groundwater basins.

Winter storms have provided enough short-term relief to our imported supplies from Northern California that Metropolitan will no longer require 自2022年6月以来，对其六个成员机构和近700万人实施了紧急限制. 多亏了潮湿的天气和 increased 国家水利工程拨款，大都会也在3月份开始 refilling its storage包括钻石谷湖在内，这是三年来的第一次.

The recent swings in weather from dry to wet point to the variable and extreme weather conditions that have made managing our water resources increasingly challenging. 加州的天气将再次变干, possibly as soon as next year, 我们的另一个进口水源是 the Colorado River -继续面临重大限制. 二十多年的干旱和严重干旱导致该系统上的水库降至30万立方米 historic low levels，危及西南地区赖以生存的供水和发电.

我们必须重建储粮储备，为下一个干旱期做准备, 投资当地供水和供水基础设施，寻找继续减少用水的方法. 在气候变化面前，我们可以共同建设南加州的水资源弹性.

Lifting Emergency Restrictions

由于北加州供水条件的改善, 大都会董事会在3月份采取了行动 remove 它的水资源短缺紧急情况和紧急水资源保护计划 since June 2022 required member agencies dependent on extremely limited water supplies from the State Water Project to restrict outdoor watering to one day a week or adhere to certain volumetric limits.

在过去的九个月里，他们努力节约用水， these communities in portions of Los Angeles, 文图拉县和圣贝纳迪诺县帮助延长了全年的可用供水.

一些地方限制可能仍然存在. 居民应该联系当地的供水商，了解他们社区最新的用水要求.

在气候剧烈变化的时代补充我们的储备

尽管最近的天气状况缓解了那些依赖国家水利工程的人最严重的紧急情况, 南加州的水问题远未结束.

Rapid swings in weather means that dry conditions could return as early as next year. California remains under a statewide drought emergency and the future availability of our Colorado River supplies is uncertain.

We are taking advantage of this year’s wetter conditions and increased State Water Project allocation to store as much water as possible in Diamond Valley Lake and other storage accounts so that they can be accessed by communities across our service area when the next inevitable dry period returns.

Thanks to these storms, 以及南加州人对水的高效利用, 我们预计今年能够几乎弥补过去三年的全部撤资.

随着大都会继续进行重大投资，以确保整个地区未来的供水可靠性, 我们要求居民和企业继续承诺，使保护成为一种生活方式.

我们必须保护科罗拉多河

Southern California relies on the Colorado River for about 25 percent of its water supply. But the system is in the midst of a 23-year drought, the most serious in 1,200 years. 为了防止系统的蓄水池下降到灾难性的水平, 联邦政府已经指示盆地的七个州, including California, 制定计划，从2023年开始减少对河流的使用.

California and the six other Colorado River Basin states have presented Reclamation with two different proposals 我们将如何减少对河流的需求. 垦务局正在审查这些建议.

While the seven states have not yet reached agreement on how to reduce use in the near-term, these proposals are just a first step; there will be more opportunities to reach consensus throughout the environmental review process.

We are committed to working with our partners on the river to develop a consensus-based approach to managing drought conditions on the Colorado River.

Ensuring the sustainability of our Colorado River supplies will require the 40 million people and 6 million acres of farmland that depend on this water source to reduce reliance on the river.

禁止商业、商业部门使用装饰草坪

For more than a decade, 大都会鼓励拆除非功能性草皮, 或者没有社区或娱乐用途的草地, 取而代之的是更可持续的加州友好型和本地植物. 这些努力产生了变革性的影响, 导致超过2亿平方英尺的草地被清除, saving enough water to serve 62,000 homes a year.

帮助该地区向更适合气候的景观过渡的承诺比以往任何时候都更加坚定.

大都会的董事会在2022年向前迈出了一步，通过采用一种新型草坪来消除纯粹的装饰性草坪 resolution that strongly recommends that cities and local water agencies across Southern California pass ordinances 禁止浇水和安装无功能的草皮, largely in commercial sectors, as well as HOAs.

我们鼓励市民继续利用我们的回扣来进行改造 bewaterwise.com.

共同投资于长期解决方案

From 2019 through 2022, 加州经历了有记录以来最干旱的三年, putting an incredible strain on our water resources and infrastructure and resulting in the most stringent water restrictions in Southern California’s history.

大都会及其26个成员机构是 working together 通过建设基础设施来提高整个地区的恢复能力, 增加本地供应和储存, expanding partnerships, advancing water-use efficiency and planning for the escalating impacts of climate change.

大都会也在加快我们的发展 Pure Water Southern California 水循环利用项目，创建一个适应气候变化的供水系统, 目标是在2028年开始初步运营.

It will take a comprehensive, collaborative and innovative approach to ensure we have the water we need for future generations as climate change continues to challenge how we manage our water supplies.

Conservation Makes Us Stronger

Southern California receives water from three aqueducts: The Colorado River Aqueduct, which we own and operate; the California Aqueduct, which carries our share of State Water Project supplies; and the Los Angeles Aqueduct, 为洛杉矶市提供服务.

Today, 我们把本地资源的开发和保护作为我们的“第四渡槽”,“补充我们的进口供应，加强我们对干旱和气候变化的适应能力.

The great news is that Southern Californians have embraced a conservation ethic – per capita water use has dropped nearly 40 percent since 1990, 尽管人口在增加.

如果没有保护，干旱的影响将会更加迅速和严重. 每省下一滴水，我们就可以再储存一滴水，以备干旱时期使用.
