亚利桑那州已加入内华达州，共同对特朗普政府提出的削减其科罗拉多河水份额的计划展开法律斗争。
Arizona has joined Nevada in its legal battle against the Trump administration's proposed cuts to their shares of the shrinking Colorado River.
此举发生在内政部今夏宣布限制措施之后，该措施可能在未来两年根据河流状况，大幅削减下游州——亚利桑那州、加利福尼亚州和内华达州——的供水量。
The move comes after the interior department announced restrictions this summer that could slash the water supplied to lower basin states – Arizona, California and Nevada – over the next two years depending on the river's condition.
科罗拉多河的主要水库米德湖和鲍威尔湖水位已降至历史最低点，原因是过度使用和气候变化。
The river's major reservoirs, Lake Mead and Lake Powell, have plummeted to historically low levels, due to overuse and a changing climate.
共享该水流的各州陷入僵局，上游州认为下游州应对水库短缺负责，因此应承担最大幅度的削减。联邦政府的介入发生在各州未能在多个期限前达成共识之后。
The states sharing the waterway were at an impasse with the upper basin states arguing that their downstream counterparts were responsible for the reservoir's water shortages and should thus face the largest cuts. The federal government's intervention came after the states missed several deadlines for a consensus.
人们担心，如果水库水位继续下降到一定程度，河流将实际上无法向下游输送水，这种情况被称为“死水池”。
The fear looming over the state of the river is that if reservoir levels plunged far enough, the waterway would effectively not be able to flow downstream, a so-called deadpool.
上游州——怀俄明州、科罗拉多州、犹他州和新墨西哥州——被豁免于此次削减，这一豁免引起了下游州领导人的强烈批评。
The upper basin states – Wyoming, Colorado, Utah and New Mexico – were spared from the water cuts, an exemption that has drawn sharp rebuke from the leaders of the lower basin states.
“我们正在划清界限，”亚利桑那州州长凯蒂·霍布斯在周五的声明中表示，“我正与内华达州一起采取法律行动，因为联邦政府拒绝让上游州对其应向亚利桑那州输送的水负责，并威胁要实施远超《下游州协议》的严苛削减措施。”霍布斯继续说道，她指的是她所在州、加利福尼亚州和内华达州之间的一项为期两年的自愿节水协议。
"We are drawing a line in the sand," Arizona governor Katie Hobbs said in a Friday statement "I am taking this legal action alongside Nevada because the federal government refuses to hold the Upper Basin accountable for the water deliveries they owe Arizona and is threatening to force draconian cuts that go well beyond the Lower Basin Agreement," Hobbs continued, referring to a two-year-voluntary water conservation pact among her state, California and Nevada.
亚利桑那州水资源部门主管汤姆·布施亚茨克表示：“在此刻介入内华达州的诉讼是必要的，以便亚利桑那州保护其对科罗拉多河水的合法权利，同时为与加利福尼亚州和内华达州合作、共同保护科罗拉多河系统留出前进的道路。”内政部发言人未就联合诉讼立即回应置评请求。
Tom Buschatzke, the director of Arizona's water department, said "intervention in the Nevada lawsuit is necessary at this time for Arizona to protect its legal rights to Colorado River water while preserving a path forward to achieving a collaborative outcome with California and Nevada to protect the Colorado River system". An interior department spokesperson did not immediately respond to a request for comment on the joint litigation.
