US Interior Department: Colorado River Water Cuts for California, Nevada, Arizona

• California, Nevada, and Arizona will collectively receive 1.25 million acre-feet less water over the next two years.
• The water cuts are part of a proposed sharing agreement among lower-basin states to address the drought-stricken Colorado River.
• The operating guidelines create a decade-long framework for managing Lake Powell and Lake Mead, ensuring protection of federal infrastructure.

The federal Interior Department has issued its final plan for Colorado River operations over the next two years, which includes severe cuts to water allocation for California, Nevada, and Arizona. The three lower-basin states will collectively receive 1.25 million acre-feet less water each year. This reduction is part of a proposed sharing agreement that calls for voluntary reductions among the lower-basin states. California will see a decrease of 440,000 acre-feet per year, while Arizona will receive 760,000 acre-feet less and Nevada 50,000 acre-feet less. The water cuts are intended to address the drought-stricken Colorado River, which has seen its lowest water levels since 1963.

The operating guidelines issued by the Interior Department create a decade-long framework for managing Lake Powell and Lake Mead. The guidelines provide criteria to determine releases from Lake Powell, which must rely on actual hydrology and maintain a minimum elevation of 3,510 feet for operational reliability at Glen Canyon Dam. This framework is designed to ensure the protection of federal infrastructure while allowing states to reach consensus among themselves. The Interior Department noted that current water levels for both reservoirs have not been this low since 1963, highlighting the need for a long-term solution.

The severe water cuts will have significant implications for agriculture, municipalities, and hydropower generation in the region. Agricultural industries may face reduced water supplies, affecting crop yields and food production. Municipalities may struggle to meet their water demands, potentially impacting public health and safety. Additionally, hydropower generation may be impacted by the reduced water levels, which could have far-reaching consequences for energy production and reliability.

Lawyers and compliance officers should watch for the practical implications of these severe water cuts, including potential impacts on agricultural industries, municipal water supplies, and hydropower generation in the region.
