Diamond Valley 湖

Metropolitan built Diamond Valley 湖 as a promise for the future. The vast reservoir, nestled between two hillsides, plays a vital role in how we manage 和 deliver drinking water. 通过储存长达6个月的时间连同我们所有的应急物资储存账户, the reservoir serves as a critical lifeline, helping Southern California get through dry times 和 catastrophes. 它还为植物和动物提供了重要的栖息地，并为社区提供了受欢迎的娱乐设施.

Diamond Valley 湖 serves as an indispensable asset, one that reflects Metropolitan’s commitment to water reliability, environmental stewardship, 和 a climate resilient future for Southern California.

A Lasting Achievement

Diamond Valley 湖’s story is one of thoughtful planning 和 foresight. 它的建设在20世纪90年代末标志着大都会大胆和历史性的成就. Since then, 该水库帮助我们渡过了充满挑战的水环境, including several multi-year droughts. The reservoir was built to hold enough water to serve nearly 2.4 million Southern California families for a year. It stores up to 810,000 acre-feet of water (264 billion gallons), 当它投入使用时，该地区的地表水储存能力几乎翻了一番.

Greater System Flexibility

储存在DVL中的水从北加州通过州水项目及其444英里长的加州渡槽输送到水库，然后通过内陆支线和东区管道输送到水库. 如果在干旱或紧急情况下需要，储存的水可以被输送到几乎所有的大都会服务区域.

A Purposeful Location

The reservoir is in the city of Hemet in southwest Riverside County, about 90 miles southeast of downtown Los Angeles. 寻找水库地点花了四年时间，考虑了13个地点，最后领导人决定在沙漏形的钻石山谷和多米尼戈尼山谷. The location was chosen for its elevation allowing for gravity flows, clean hydroelectric power opportunities, water quality improvements, 和 proximity to Metropolitan's existing water delivery system. DVL is 4.5 miles long 和
2 miles wide 和 has depths of up to 250 feet.

Environmental Benefits

水库是保护野生动物和生态系统的自然栖息地. 附近的两个大型自然保护区为如何建设与自然和谐相处的基础设施提供了一个典范. 该水库的开发标志着公私合作的重要先例，通过关注整个生态系统而不是单个栖息地，将环境保护提高到一个新的水平.

Southwestern Riverside County Multi-Species Reserve

About 14,在西南河滨县多物种保护区内，有1000英亩的开放空间被保留下来，该保护区围绕并连接着钻石谷湖和斯金纳湖.
With creation of the reserve, 大都会帮助促成了加州第一个多物种保护协议.
The reserve is home to at least eight types of habitat 和 many sensitive bird, animal 和 plant species.
The reserve contains more than 30 miles of biking, hiking 和 equestrian trails.

Santa Rosa Plateau Ecological Reserve

圣罗莎高原生态保护区有一些南加州最后的春天池塘，那里养着神仙虾, wintering waterfowl 和 spring wildflowers.
Metropolitan joined Riverside County, 加州野生动物保护委员会和大自然保护协会购买并保护了6个,800 acres.
这一努力帮助保护了宝贵的土地，同时也获得了开发钻石谷湖的批准，为南加州提供了可靠的供水.
The reserve has a network of multi-use trails, a comprehensive interpretative program, 和 a visitor center. 点击在这里 for more information.

Recreational Opportunities & Challenges

钻石谷湖提供了高质量的娱乐机会，可以继续保护我们的饮用水供应，并与自然环境和谐相处. T在这里 are an array of recreational opportunities including boating, 钓鱼, canoeing, kayaking 和 sailing, as well as adjacent multi-purpose trails, bike paths, 和 public park facilities. Amenities include 2.5 miles of shoreline 钓鱼, a marina 和 concession area, 和 park facilities.

检查在这里 for more general information about the marina 和 recreation.

On the Water

水库提供划船、钓鱼、皮划艇、独木舟和帆船的机会. Boating 和钓鱼 are available year-round. To support the reservoir’s recreational values 和 protect drinking water quality, Metropolitan established rules 和 regulations for visitors, recreational users, 和 boaters at Diamond Valley 湖. 禁止身体接触(如游泳、滑水和使用个人船只). Boats are required to have clean-burning engines that use direct fuel injection. 游客有责任了解并遵守所有加州划船和水路部门以及鱼类和野生动物部门的规定.

检查在这里 for a full list of boating rules, requirements 和 rental information.

Invasive Species Challenge

水质和系统运行的最大问题之一是入侵斑驴贻贝的扩散. The mussels, which are spread by commercial ships 和 recreational boats, can multiply rapidly, clog pipes 和 pumping machinery, 和 ruin the ecology of lakes 和 reservoirs. Once the lake ecology is altered, the growth of algae can occur 和 affect the taste of a region’s drinking water. 这些贻贝是在科罗拉多河沿岸的哈瓦苏湖、米德湖和莫哈韦湖发现的. They have not been found at DVL. To prevent their spread, 访问DVL的船只有下水要求，船只操作员将进行面谈，以确保列出要求在这里 have been followed.

Construction Notables

The construction of DVL’s Don Owen West dam, Carl Boronkay East大坝和Saddle大坝是美国最大的土方工程之一. 该工程在1995年至2000年期间进行，涉及地基开挖超过4000万立方码的土和1.1亿立方码的路堤建设. 一座名副其实的岩石山从水库的南缘移开，横跨谷底，形成两座水坝, 一个2.1 miles long, the other 1.5 miles long, at each end of the 4.5 mile valley. 土芯堆石坝的材料均在工程范围内采购. T在这里 were two rock processing plants set up for the project 和 together, 它们的产量超过了加州任何单一商业加工的能力. The construction equipment used — shovels, loaders 和 trucks — 是业内最大的，并为土和岩石运动设定了新的标准吗.

使 & Preserving History

DVL的发展是基于我们对服务客户和保护环境的承诺. Along the way came remarkable historical discoveries. For seven years, 两人古生物学小组在山谷的两端188bet棋牌平台，每班10小时, 20-hour days, six days a week, following massive earth-moving equipment. They would find, what many experts consider, a collection of fossils to rival the famous La Brea Tar Pits. The area was called, “The Valley of the Mastodons.” One of the more famous discoveries was Max the Mastodon. More than two decades after the discovery, 人们确定马克斯是50多年来在北美命名的第一个新的乳齿象物种(太平洋猛犸象), the Pacific mastodon). During excavation, bones 和 skeletons were found from extinct mastodons 和 also mammoth, 骆驼, 懒惰, dire wolf 和 long-horned bison.
