What You Think You Know About the Great Salt Lake Might Be Wrong.

The lake generates $2.5 billion annually in direct economic productivity. It contributes up to 10% of mountain snowpack and 50% of valley precipitation through lake-effect storms — helping sustain a $1.6 billion ski tourism industry. How big is the difference? Salt Lake City averages 16–20 inches of precipitation per year. Wendover — at similar latitude and elevation, but without the lake — gets just 5. The lake is the reason the Wasatch Front isn’t a desert.

10 million migratory birds from over 400 species depend on the lake every year. Brine shrimp have thrived in its waters for 600,000 years. The Great Salt Lake is a designated Western Hemisphere Shorebird Reserve — one of the most important bird habitats on Earth.

Over 120 square miles of Farmington Bay lakebed are now exposed, including 21 square miles of dust “hotspots.” Wind events send dust containing arsenic, mercury, and lead across the Wasatch Front, where 2.5 million people live downwind.

Since 2022, Utah has committed nearly $1 billion in water conservation, enacted dozens of new water laws, and delivered approximately 400,000 acre-feet of water to the lake between 2021–2025. The toolbox is bigger than ever — and growing.

The south arm ended the 2025 water year at 4,191.1 feet — the third-lowest recorded elevation since 1903. Neither arm of the lake has been in the “healthy” range since 2012. Human water diversions, not natural cycles, are driving the unprecedented decline.

Republican lawmakers, mineral extraction companies ($1.1 billion/year), ranchers, ski resorts, the LDS Church, and the U.S. military have all joined the effort. The Great Salt Lake is America’s sole source of magnesium — a USGS-designated critical mineral essential to national defense.

In 2024, watering residential lawns alone depleted 408,500 acre-feet — equivalent to one quarter of all agricultural water use in the basin. Outdoor use accounts for 96.9% of all municipal and industrial water depletion. Your sprinkler system is part of the problem.

There is no replacement. Nearly 1.7 million Eared Grebes arrive at the lake flightless during their molt, entirely dependent on brine shrimp. Up to 40% of all Wilson’s Phalaropes on Earth fuel up here before nonstop flights to South America. If this lake fails, they have nowhere else to go.

Climate change accounts for roughly 9% of the lake’s decline. The rest is human water use: agriculture (65%) and municipal/industrial use (27%) of human-caused depletions. The updated water budget confirms all sectors must contribute to conservation — and that the solutions are in our hands.

To reach the minimum healthy elevation (4,198 ft) by 2055, mean annual inflows need to be approximately 2,465,000 acre-feet per year. Between 2000–2025, inflows averaged only 1,665,000. Mountain groundwater storage has been below average since 2012. The gap is real and the clock is running.

The vast majority of water applied to lawns is lost to evapotranspiration — absorbed by grass and soil and released into the atmosphere. Updated research shows that 91% of outdoor water use is depleted and never returns to the system. In 2024, residential lawn watering alone consumed 408,500 acre-feet of water. Overwatering doesn’t help the lake — it drains it.

The lake produces 14% of the world’s magnesium, leads the Western Hemisphere in sulfate of potash production (fertilizer for almonds and stone fruits), and supplies roughly 45% of the world’s brine shrimp eggs for global aquaculture. It also contains an estimated 410,000 metric tons of lithium. Total mineral extraction value: over $1.1 billion per year.

That salinity is precisely the asset. It prevents freezing — enabling year-round lake-effect snow. It sustains a $57 million brine shrimp industry in predator-free water. And it feeds 100,000+ acres of solar evaporation ponds producing over $1 billion in minerals annually. But there’s a catch: in 2022, salinity approached brine shrimp’s survival limit. Too salty is just as dangerous as too dry.

California’s Owens Lake was drained in the 1920s. The result: decades of toxic dust storms and a cleanup bill exceeding $2.5 billion — still rising. The Great Salt Lake is far larger, and 2.5 million people live nearby. Communities near collapsed saline lakes worldwide have seen cancer rates rise 50–60% and infant mortality climb 60%. This isn’t hypothetical — it’s what happens when lakes die.

The lake’s moisture creates the “Greatest Snow on Earth.” Dust from exposed lakebed darkens snowpack and accelerates melting. The lake needs to rise roughly 7 feet to reach the Governor’s healthy-level target by 2034. With billions of viewers watching and cameras trained on our mountains, the condition of the Great Salt Lake will be a headline. Your commitment today helps shape which story gets told.

It’s been studied — and the numbers don’t work. A pipeline from the Pacific would span 600+ miles with a 4,200-foot elevation gain over major mountain ranges. Estimated construction cost: over $100 billion. Annual electricity to operate: 400 megawatts — 11% of Utah’s total power demand — at a cost of $300 million per year, while emitting nearly 1 million metric tons of CO₂ annually. What about piping from another state’s rivers instead? Every Western state is already over-allocated — the Colorado, Snake, Missouri, and Mississippi river systems all face their own shortages. No state has excess water rights they’re willing to sell. Researchers concluded that conservation is the only solution fast enough to save the lake in time.
