Environmental Advocates Push for More Efficient Water Use on the Colorado River
With the Colorado River facing unprecedented water shortages, a coalition of environmental groups has taken a definitive step by petitioning the federal government. Their message is clear: ensure that the river’s water is only used for “reasonable” and “beneficial” purposes, eliminating waste in the process. This call to action comes as states dependent on this vital water source must agree on new sharing rules by 2026, with a preliminary agreement needed by mid-November to avoid federal intervention.
The organizations are urging the Bureau of Reclamation to address water waste in the Lower Basin states—California, Arizona, and Nevada. They argue that curbing wasteful practices is essential for the river’s long-term sustainability, while others express concerns about potential impacts on farmers and consumers.
Mark Gold, a former director with the Natural Resources Defense Council, emphasized the urgency of the situation, stating, “We don’t have a management future for the Colorado River right now and it’s getting pretty scary. We should be dealing with this as a water scarcity emergency, and one of the things that you really want to do in an emergency is, let’s deal with water waste first.”
Challenges in Defining ‘Reasonable’ and ‘Beneficial’ Use
The Bureau of Reclamation’s guidelines stipulate that water deliveries must not exceed what is required for beneficial use, but this definition remains vague. Cara Horowitz and her students at UCLA’s Frank G. Wells Environmental Law Clinic have investigated this ambiguity, finding little clarity in existing government records. They contend that the bureau lacks a process to evaluate whether states are preventing wasteful practices, calling for periodic reviews in their petition.
While defining these terms is complex, some argue it’s necessary. However, Sarah Porter from Arizona State University cautions, “It’s potentially a whole can of worms that we need to approach very carefully. Who gets to be the entity that decides what’s an appropriate amount of use for any particular water user or community?”
The environmental groups suggest incentivizing farmers to adopt more efficient irrigation methods and to consider crop suitability for local climates. Instances of wasteful practices include the year-round flood irrigation of water-demanding crops in desert regions and the use of water-intensive cooling systems in urban areas.
Farmers and Urban Concerns
In California’s Imperial Valley, which relies entirely on the Colorado River, farmers like Andrew Leimgruber are already adopting water-saving measures. Nonetheless, he worries that reducing “unreasonable” water use could lead to food shortages, affecting consumers far from the region. Bill Hasencamp from the Metropolitan Water District of Southern California supports reviewing water use but warns that legal disputes could arise, complicating efforts to address the river’s crisis.
California’s Approach as a Potential Model
Some experts look to California’s constitution, which includes a reasonable and beneficial use provision, as a potential framework. This flexible approach allows state water regulators to adapt interpretations over time, as Felicia Marcus of Stanford University notes. In drought situations, California has used this provision to prioritize certain water uses over others.
Exploring Comprehensive Solutions
As the Colorado River crisis intensifies, a range of solutions is under consideration. Limiting population growth in arid regions, expanding desalination projects, and increasing wastewater recycling are among the suggestions. Noah Garrison of UCLA highlights the importance of adopting innovative water management strategies.
With critical deadlines approaching, some experts argue for a more decisive role from federal authorities. Felicia Marcus asserts, “There’s responsibility here to be the water master on the river or it gets thrown to the Supreme Court, which will take years to work its way through.” The current petition serves as a reminder of the tools available to address this pressing issue.
