The U.S. Drought Monitor has released updated data indicating widespread aridification across 43 percent of the United States, with critical depletion observed in the Colorado River Basin.

美國乾旱監測中心發佈了更新數據，指出美國 43% 的地區出現廣泛乾涸，而科羅拉多河盆地的水資源損耗尤其嚴重。

The current hydrological landscape is characterized by a heterogeneous distribution of drought severity, ranging from 'Abnormally Dry' (D0) to 'Exceptional' (D4). While transient precipitation from Tropical Storm Arthur facilitated a temporary mitigation of drought in the Southeast, meteorological projections suggest a recurrence of flash drought conditions by mid-July due to the establishment of a high-pressure system. Concurrently, the Mountain West and Northwest are anticipated to experience intensified aridification. In the Corn Belt, an expansion of drought is projected for the northern sector, while the southern region is expected to transition toward an 'abnormally dry' designation.

目前的水文景況是以不同嚴重程度的乾旱為特徵，範圍從「異常乾燥」(D0) 到「極端乾旱」(D4)。雖然熱帶風暴亞瑟帶來的短暫降雨暫時緩解了東南部的乾旱，但氣象預測顯示，由於高壓系統的形成，到 7 月中可能會再次出現閃電乾旱條件。同時，山區西部與西北部預計將經歷更強烈的乾涸。在玉米帶，北部預計乾旱將擴大，而南部則預計將轉向「異常乾燥」的定義。

Of particular institutional concern is the degradation of the Colorado River system, which sustains 40 million residents and 5 million acres of agricultural land. Lake Powell has reached its lowest recorded summer elevation, with current storage at 23 percent of capacity. The U.S. Bureau of Reclamation has indicated that the reservoir may reach the minimum power pool—the threshold jeopardizing hydropower generation at Glen Canyon Dam—by 2027. This systemic failure is attributed to a multi-decadal chronic drought exacerbated by increased evaporation rates associated with global thermal elevation. To mitigate these risks, the Bureau has commenced the transfer of water from the Flaming Gorge reservoir and reduced outflows to Lake Mead.

機構方面特別關注的是科羅拉多河系統的惡化，該系統維持著 4,000 萬居民與 500 萬英畝農地的生存。鮑威爾湖已達到其紀錄最低的夏季水位，目前儲量僅為容量的 23%。美國垦務局指出，水庫水位可能會在 2027 年前達到最低發電水位——此臨界點將危及格倫峽谷壩的水力發電。這種系統性失效歸因於數十年的長期乾旱，並因全球氣溫上升導致的蒸發率增加而惡化。為了緩解這些風險，垦務局已開始將水從火焰峽谷水庫轉移，並減少流向米德湖的流量。

These environmental pressures have precipitated a diplomatic crisis among the seven basin states. The necessity of negotiating new water-sharing agreements prior to an October deadline has resulted in a deterioration of inter-state collegiality. Stakeholders in the Upper Basin report dire conditions, with specific municipalities, such as Emery and Apple Valley, facing imminent or current potable water exhaustion. The prevailing consensus among officials is that the current deficit cannot be rectified by isolated wet years, but rather requires a permanent shift in the precipitation regime.

這些環境壓力導致了七個盆地州之間的外交危機。由於必須在 10 月期限前協商新的分水協議，導致州際間的協作關係惡化。上盆地的持份者報告情況 dire，部分市鎮（如 Emery 與 Apple Valley）面臨飲用水即將耗盡或已經耗盡的危機。官員們目前的共識是，目前的虧損無法透過單獨的多雨年份來修正，而需要降雨模式產生永久性的轉變。

The United States continues to face significant hydrological instability, with the Colorado River system approaching a critical failure point in power production and water supply.

美國繼續面對嚴重的水文不穩定，科羅拉多河系統在發電與供水方面正接近臨界失敗點。
