Investing in Our Future
促进萨克拉门托-圣华金三角洲的可持续发展
萨克拉门托-圣华金三角洲与加州其他任何地方都不一样. 同时也是心脏的心脏 国家的供水系统, 河口是超过35种濒危本土动植物的家园, 数十个历史悠久的社区和数十万英亩的农田. The fertile peat soil of its islands produces an estimated $965 million in agricultural crops annually and its ecosystem supports the commercial salmon industry on the West Coast. 三角洲同时也是全州水利基础设施的重要一环, 一个重要但脆弱的生态系统, 是我们经济的引擎,也是500人的家园,000 people. It’s also a region that has witnessed major land-use and landscape changes over the past centuries.
The Delta was once a vast marshland covered with tules and teaming with wildlife. In the mid-1800s, settlers built levees to drain and reclaim the land and today about 95% of the original wetlands and floodplains are gone. In this highly altered environment, non-native species have thrived, over-running native species. Striped bass, 亚洲蛤和许多其他入侵者, large and small, 吃的要么是当地居民,要么是他们赖以为生的食物.
Recognizing the importance of stabilizing the Delta and securing our water future, 大都会购买了一些 Delta islands in 2016. 使我们对国家和地区水资源的承诺更加透明, 大都会董事会正式通过了一项更新的 《湾三角洲政策纲要 in October 2022. As a responsible landowner and conscientious neighbor invested in environmental stewardship, 我们致力于以科学为基础的流域管理, multi-benefit environmental initiatives and community-based partnerships with local stakeholders on these islands and throughout the region.
韦伯小道的多效益景观修复与耕作
2024年7月10日的混合公共会议
The Metropolitan Water District of Southern California will host the first public meeting for two farming and habitat restoration projects on the central Delta islands of Webb Tract on Wednesday, July 10 at 11 a.m. in Oakley. These projects, proposed by Metropolitan and funded by the 萨克拉门托-圣华金三角洲 Conservancy, 将改变韦伯小道.
Malinda Stalvey, Metropolitan project manager, will present an overview of the two projects. 其他主持人将讨论农业机会, 湿地初步规划, 潜在的生态文化价值, 而科学监测大约为5,500-acre island located between Bradford Island and Frank’s Tract in the central Delta. 时间将留给提问和回答.
Join us in person at the Big Break Visitor Center in Oakley or participate via Zoom. 会议预计将持续一个小时,但可能会延长到下午12:30.m. 如果需要额外的时间回答所有问题.

三角洲面临着许多挑战, 大都会致力于寻找可行的方法, cooperative solutions. 都市区拥有的三角洲韦伯土地, Bacon Island, Bouldin Island and Holland Tract – enable us to explore cooperative approaches to improve the declining ecosystem and promote water reliability. 与我们董事会通过的一致 粤港澳政策框架, we contribute to research and science-based watershed management that improves water quality and reliability, restores native habitat in support of protected and endangered species and promotes sustainable agricultural practices. 我们也在研究气候变化的风险, 管理泥炭土以减少碳排放和加固堤坝.
我们正在与州和联邦机构合作, technical experts, academia and environmental organizations to develop and participate in the studies and projects highlighted below.
Collaborative, multi-benefit projects on Metropolitan's Delta island properties have focused on land use adaptation and habitat restoration opportunities, subsidence reversal efforts and promoting resilience against climate change while mitigating carbon emissions.
三角洲岛屿适应规划项目,博尔丹岛
由该州1号提案拨款资助, this project on Bouldin Island includes a mosaic of land uses for reversing subsidence and promoting sustainable agricultural practices, carbon sequestration, 温室气体减排, 改善水质及恢复生境
多利益景观修复,韦伯道
A $20.9 million grant awarded by the Delta Conservancy will fund construction of wetlands and rice fields on Webb Tract to encourage native vegetation and enhance ecosystem benefits.
While the project supports the conservation goals established by the State’s 30x30 Initiative, 它不会为现有和拟议的项目提供缓解措施, 包括三角洲运输工程.
浮动湿地研究,Bouldin岛
这是博尔丹岛的试点项目, 大都会之间的合作, DWR, 加州大学戴维斯分校流域科学中心和其他实体, 是研究漂浮泥炭湿地吗, 历史上存在于三角洲地区. 如果这些浮动湿地可以重新建立, 它可以改善生态系统,降低堤坝倒塌的风险.
三角洲冶炼厂先导繁殖研究

鲑鱼捕食和存活率研究
Metropolitan has provided access to its Delta islands to support a number of scientific studies investigating survival rates of juvenile Chinook salmon, 该地区濒临灭绝的本地物种, in relation to the increasing presence of non-native predators such as the largemouth bass and proliferation of non-native submerged aquatic vegetation.
合作实现修复
在过去的三十年里, federal, 州和地方机构, 还有非政府机构, have worked together, contributing hundreds of millions of dollars to projects that help restore and preserve the Delta’s ecosystem. 除了它拥有的岛屿上的项目, Metropolitan partners with other agencies and organizations on projects that benefit the Delta’s natural systems.
California EcoRestore
Metropolitan participates in this multi-agency initiative led by the California Department of Water Resources that aims to advance more than 30,000英亩的关键栖息地恢复和改善, Suisun Marsh and Yolo Bypass region to support the Delta’s long-term health and its native fish and wildlife species through cutting-edge science and shared expertise and investment.
萨特旁路修复术
Metropolitan engages in scientific studies with staff at academic institutions and other partner and water agencies to coordinate research on habitat restoration and grant opportunities in the Sutter Bypass, an approximately 14,000英亩的洪泛区有助于维持当地的生态系统进程, groundwater recharge, 食物网的生产和水生物种的栖息地.
Yolo Bypass Restoration
Metropolitan supports habitat restoration work in the Yolo Bypass Wildlife Area, a 60,000-acre floodplain that protects Sacramento from flooding and provides important habitat to migrating waterfowl and endangered fish populations. 最近的改进增加了220英亩的管理湿地, 提高了现有湿地的生产力, 加强野生动物友好型稻田管理, reduced on-site flooding and increased and improved public recreational and educational access to the area.
海湾三角洲跨部门科学协调
Metropolitan participates in the Delta Stewardship Council’s Delta Plan Interagency Implementation Committee’s Restoration Subcommittee, 科学资助和治理倡议, and Science Enterprise Subcommittees to identify and implement restoration activities in the Delta that promote natural and human communities, resiliency to stressors, adaptation to change, 娱乐无障碍.
