Conservation Lawsuit Advances: Utah Faces Accountability Over the Great Salt Lake Crisis
Conservation groups' landmark lawsuit pushes Utah to address environmental and health threats facing the Great Salt Lake.
Utah Faces Lawsuit Over Shrinking Great Salt Lake
The Great Salt Lake, North America’s largest saltwater lake, is rapidly diminishing, sparking urgent action by conservation groups who have sued the state of Utah for failing to meet its legal obligations to protect the lake. A recent ruling by Judge Laura Scott has allowed the landmark case to proceed, marking a critical moment for environmental accountability and the future of this vital ecosystem.
The Crisis at the Great Salt Lake
The Great Salt Lake has dropped more than 22 feet since 1986, exposing more than half of its historic lakebed and threatening to unleash unprecedented ecological and public health disasters. The drivers behind this decline are extensive upstream water diversions, largely for agriculture and development, which have diverted hundreds of billions of gallons from the lake and reduced its inflow by at least 62%—according to recent studies.
Permanently lowering lake levels jeopardizes:
- Critical habitat for millions of migratory birds, including ducks, pelicans, and the rare Wilson’s phalarope.
- Public health of local residents, due to toxic dust storms from exposed lakebed sediments containing arsenic and mercury.
- Regional industries, including mineral extraction, recreation, and brine shrimp harvesting that contribute billions to Utah’s economy.
Legal Grounds: The Public Trust Doctrine
The heart of the lawsuit is the public trust doctrine, a principle that obligates the state to safeguard public resources—including navigable waters—for the benefit of current and future generations. Conservation and community groups, represented by Earthjustice and other legal partners, argue that Utah has breached this trust by failing to take effective steps to ensure the lake receives the water it needs.
Judge Scott’s decision categorically rejected the state’s argument that the doctrine does not apply to the Great Salt Lake’s waters. Her ruling stated: “Defendants have failed to explain how the public trust doctrine can possibly protect the acknowledged ‘public trust values of navigation, commerce, and fishing’ if there is no obligation to preserve the waters themselves.”
Who Are the Plaintiffs?
- Earthjustice-a nonprofit legal organization specializing in environmental issues.
- Utah Rivers Council-an advocacy group focused on safeguarding water resources in Utah.
- Utah Physicians for a Healthy Environment-medical professionals highlighting the health hazards of air pollution and exposed toxins.
- Sierra Club-prominent national environmental group supporting protection and restoration efforts.
Together, these organizations are calling for significant changes in water management and for the state to fulfill its public trust obligations.
Impact on Wildlife and Ecosystems
The shrinking Great Salt Lake endangers one of the most important inland shorebird habitats in the Western Hemisphere. Millions of birds depend on the lake for food and resting grounds during migration.
What others are reading
Specific impacts include:
- Loss of wetland habitat critical for nesting and foraging.
- Reduced food sources as lower water levels impact brine shrimp and insect populations.
- Heightened risk of extinction for rare bird species.
Human Health Risk: Toxic Dust Exposure
As lake levels drop, vast stretches of dry lakebed are exposed. These newly revealed surfaces contain sediment loaded with heavy metals and industrial residues, notably arsenic and mercury. Winds carry these toxins into nearby communities, contributing to air pollution along the Wasatch Front and posing serious health hazards.
- Air quality degradation due to dust storms.
- Increased respiratory and cardiovascular problems, especially among children and seniors.
- Worsening public health crisis, compounding existing pollution issues in Northern Utah.
Economic Consequences
The Great Salt Lake supports multi-billion dollar industries. Declining water levels threaten these economic sectors:
- Mineral extraction: Companies depend on lake water for harvesting minerals like magnesium and salt.
- Brine shrimp harvesting: The lake is a global center for brine shrimp production, feeding aquaculture and fish farms worldwide.
- Outdoor recreation: Lower water levels reduce opportunities for boating, hunting, and birdwatching.
Lawsuit Details and Legal Arguments
Case Background
Conservation and community health groups filed their suit in September 2023, citing that Utah’s management of upstream water diversions was driving the lake toward ecological collapse. The suit argues the state should immediately reduce water diversion and implement greater conservation measures to restore inflow to sustainable levels.
Judge Scott’s Ruling
On March 27, 2025, Judge Laura Scott denied the state’s request to dismiss the case, affirming that the plaintiffs’ arguments hold merit under the public trust doctrine. This decision is a significant victory for conservationists, forcing the state to face its legal responsibilities.
Judge Scott described the state’s position as “extreme,” given its claim that the doctrine did not apply to navigable waters. Her ruling sets a precedent for how public resources must be managed by government trustees.
Next Steps in Litigation
- Plaintiffs continue to advocate for immediate and long-term water conservation strategies.
- The case now moves forward with further hearings, data gathering, and debate over actionable remedies.
- Experts estimate a 35% reduction in human water consumption upstream is needed just to begin restoring the lake.
Community and Advocacy Response
Environmental organizations and local advocates applaud the court’s decision as a turning point, emphasizing the need to shift from rhetoric to actionable plans:
- Zach Frankel, Utah Rivers Council: “This ruling forces Utah to take responsibility for protecting the Great Salt Lake, rather than relying on marketing and empty promises.”
- Deeda Seed, Center for Biological Diversity: “The lake is still in crisis, but now we have an opportunity to push for real solutions.”
- Dr. Brian Moench, Utah Physicians for a Healthy Environment: “Today’s ruling gives everyone who lives in Northern Utah a much better chance at avoiding unprecedented health hazards.”
Potential Solutions and Policy Recommendations
Experts advocate for a range of solutions to halt the lake’s decline and restore its ecological balance:
- Water usage reduction: Implementing stricter limits on agricultural and municipal water diversion upstream.
- Conservation incentives: Promoting water-saving technologies and practices among residents and businesses.
- Leak detection and infrastructure upgrades: Repairing and modernizing pipelines and canals to reduce waste.
- Policy reforms: Revising state laws to recognize the public trust doctrine’s obligation to maintain navigable waters.
- Habitat restoration: Re-establishing wetlands and riparian zones around the lake to support biodiversity.
Community Engagement: How Can You Help?
Protecting the Great Salt Lake is a collaborative effort. Individuals and communities can support conservation:
- Advocating for stricter water conservation measures with local and state representatives.
- Participating in educational campaigns to raise awareness about the lake’s ecological and economic significance.
- Volunteering for clean-up and restoration projects in surrounding wetland areas.
- Supporting organizations involved in the lawsuit and broader conservation efforts.
