美国联邦政府公布了一项科罗拉多河管理框架，要求亚利桑那州、加州和内华达州在2036年前共同承担最多300万英亩英尺的用水削减 [1]。内政部长道格·伯根姆表示，"这一框架提供了灵活性来应对不断变化的水文条件，同时为盆地各州继续为可持续的、基于共识的解决方案而努力保留了机会" [1]。
该管理方案为期十年，水资源管理决策每两年制定一次 [1]。在此期间，科罗拉多州、犹他州、新墨西哥州和怀俄明州暂时豁免强制削减 [1]。方案规定科罗拉多河年度释放量范围介于500万至1200万英亩英尺之间 [1]。超过4000万人依赖科罗拉多河获取水资源，这包括七个美国州、多个部落以及墨西哥 [1]。
The U.S. federal government has unveiled a framework for managing the Colorado River that would require Arizona, California, and Nevada to collectively reduce water consumption by up to 3 million acre-feet through 2036.[1] The plan temporarily exempts Colorado, Utah, New Mexico, and Wyoming from mandatory cuts, representing an interim approach to addressing the critical water shortage affecting this major river system.[1]
Under the 10-year management framework, annual water releases from Lake Powell would range between 5 million and 12 million acre-feet, with water management decisions to be revisited every two years.[1] Secretary of the Interior Dough Burgum stated that the proposal "provides the flexibility to respond to changing hydrologic conditions while preserving the opportunity for the Basin States to continue working toward durable, consensus-based solutions."[1]
The Colorado River sustains more than 40 million people across seven U.S. states, multiple tribes, and Mexico, making the management of its water resources a critical regional concern.[1]
