Nevada Challenges Federal Colorado River Water Allocation Plan

Nevada has filed a federal lawsuit against the Department of the Interior to block its new plan for Colorado River water allocations. The state argues the plan unfairly targets Lower Basin states while requiring no mandatory water reductions from Upper Basin states. This legal challenge could force a major shift in water policy and economic planning for Southern Nevada.[1][2][3]

Under the proposed plan, Nevada faces a massive reduction in its water supply. The federal plan could cut the state's annual water allocation by 213,556 acre-feet, which would leave Southern Nevada with less than 86,500 acre-feet of water each year. For comparison, Southern Nevada used approximately 212,500 acre-feet of water in 2024.[4][5][6]

State officials argue the federal government completely ignored how these cuts would affect the local economy. The lawsuit claims the Interior Department failed to analyze the economic impact of the water cuts on Southern Nevada's $180 billion economy. Nevada is asking the court to set aside the federal Record of Decision.[7][8]
