Arizona joined Nevada in legal action against the Trump administration's proposed cuts to their shares of the Colorado River. This move came after the Interior Department announced summer restrictions that could reduce water supplied to Arizona, California, and Nevada over the next two years based on the river’s condition. Major reservoirs like Lake Mead and Lake Powell have reached historically low levels due to overuse and climate change. The lower basin states accuse the upper basin states (Wyoming, Colorado, Utah, New Mexico) of avoiding responsibility for water shortages, while federal intervention failed to resolve disagreements between the states. Arizona’s Governor Katie Hobbs stated that she is taking legal action alongside Nevada because the federal government refuses to hold the Upper Basin accountable for their water delivery obligations.
