- 内容摘要
- 该计划将从2027年起对加利福尼亚州、内华达州和亚利桑那州实施21%的科罗拉多河供水削减
- 根据这项新的10年河流管理计划，上游各州无需强制削减用水量
- 内华达州的诉讼称该计划违反了行政、环境及河流管理相关法律
美国特拉华州威尔明顿，8月24日（路透社）——内华达州周一起诉特朗普政府，以阻止其从遭受干旱侵袭的科罗拉多河削减供水的计划，称该计划可能摧毁该州，且违反了管理该河流的相关法律。
美国内政部周五敲定了这项计划，包括从2027年起的两年内，向加利福尼亚、内华达和亚利桑那三个州削减21%的科罗拉多河供水。到2028年后，对这三个所谓下游州的削减幅度可能会翻番，亚利桑那州和内华达州曾表示此举将对其经济造成严重影响。

这项为期10年的河流管理计划为全美十分之一的人口提供用水，并为600万人供电。根据该计划，所谓的上游四州——科罗拉多州、犹他州、新墨西哥州和怀俄明州——无需强制削减用水量。
该计划每两年进行一次审查，在经过三年多的谈判后，各州仍未能就如何分配水资源达成一致，以取代今年到期的旧计划。
上游各州拒绝强制削减自身用水量，辩称由于美国西部长达数十年的干旱，他们已经面临大幅减供。三个下游州则认为，所有共享该河流的七个州都必须削减用水。

内华达州、内华达州科罗拉多河委员会以及南内华达州水务局提起的这起诉讼是首个对该计划提出质疑的诉讼。诉讼已在拉斯维加斯的联邦法院提交，被告包括内政部、内政部长道格·伯古姆、美国垦务局及其局长奥布里·贝滕考特。
内政部拒绝置评，垦务局也未立即回应置评请求。
该诉讼指控政府违反了行政法、环境法以及被称为《河流法》的一系列条约、协议和法院裁决。诉讼称，政府未遵守相关要求，未考虑合理的替代方案和可预见的经济影响，未充分回应公众意见，也未对缓解措施进行充分分析。

“因此，决策者和利益相关方只能猜测联邦被告如何解读和适用《河流法》，而各方一致认为该法律管辖着这项拟议行动，”诉讼文件中写道。

- Summary
- Plan imposes 21% Colorado River water cuts on California, Nevada and Arizona from 2027
- Upper basin states face no mandatory cuts under new 10-year river management plan
- Nevada lawsuit says plan violates administrative, environmental and river-governing laws
WILMINGTON, Delaware, Aug 24 (Reuters) – Nevada sued the Trump administration on Monday to block its plans for slashing water supplies from the drought-stricken Colorado River, saying it could devastate the state and would violate the laws governing the river.
The Department of the Interior on Friday finalized its plan that included a 21% reduction in water from the river to California, Nevada and Arizona for two years starting in 2027. The cuts to the three so-called lower basin states could nearly double after 2028, a move that Arizona and Nevada have said would have huge consequences for their economies.

The four so-called upper basin states — Colorado, Utah, New Mexico and Wyoming — face no mandatory cuts under the new 10-year plan to manage the river that provides water to one in 10 Americans and generates power for 6 million people.
The plan is up for review every two years and the states were unable to agree on how to share the water after more than three years of talks to replace a plan that expires this year.
Upper basin states refused to take mandatory cuts to their water supply from the river, arguing they already face steep reductions due to the decades-long drought in the western United States. The three lower basin states say all seven states that share the river must make cutbacks in water use.

The lawsuit by Nevada, the Colorado River Commission of Nevada and the Southern Nevada Water Authority is the first to challenge the plan. It was filed in federal court in Las Vegas and named as defendants the Department of the Interior, Interior Secretary Doug Burgum, the U.S. Bureau of Reclamation and its commissioner, Aubrey Bettencourt.
The Interior Department declined to comment and the Bureau of Reclamation did not immediately respond to a request for comment.
The lawsuit alleged the administration violated administrative law, environmental law and the group of treaties, agreements and court rulings known as the Law of the River. It said the administration did not comply with requirements to consider reasonable alternatives and foreseeable economic impacts, to fully respond to comments or to adequately analyze mitigation measures.

“Consequently, decisionmakers and stakeholders are left to guess at how federal defendants interpret and apply the Law of the River, which all agree governs the proposed action,” the lawsuit said.
