The Right to Exist: Ensuring the Colorado River’s Health and Sustainability From Source to Mouth

Abstract

This paper examines the transformative potential of recognizing the Colorado River as a legal person endowed with inherent Rights of Nature. It critiques the dominant anthropocentric water law doctrines, particularly prior appropriation, which prioritize human uses and property rights at the expense of the river’s ecological health and long-term sustainability. Drawing on landmark international legal precedents that grant rivers personhood and establish guardianship models, the paper advocates for adopting a similar rights-based framework for the Colorado River. Indigenous legal principles and sovereignty are emphasized as essential to legitimizing and strengthening these efforts by integrating cultural stewardship, reciprocity, and ecological restoration into water governance. While acknowledging significant challenges—including entrenched legal doctrines, political conflicts, and enforcement gaps—the paper proposes strategic pathways combining litigation, public engagement, and scientific evidence to institutionalize Rights of Nature in U.S. water law. Ultimately, the recognition of the Colorado River’s legal personhood is presented not only as a legal innovation but a moral imperative to protect one of the American West’s most vital natural lifelines and to reshape environmental governance towards equity, sustainability, and intergenerational justice.
