The Great Salt Lake in Utah is at risk due to water withdrawals for agriculture that are lowering its level and increasing its salt content. This is threatening the ecosystem and the millions of migratory birds that rely on the lake.
Filmmaker Jaxon Derow visited the lake when it was at its lowest level and filmed the vast expanses of exposed lake bed, which is causing toxic dust storms. Without measures to restore the lake’s water levels, scientists warn that the Great Salt Lake may become dead within a couple of years. We highlight this issue in the film “Vanishing Oasis” by Derow.
The Great Salt Lake and Its Web of Life Face an Uncertain Future
The Great Salt Lake, in the state of Utah, is not only a unique natural wonder but also a critical ecosystem that supports a diverse web of life. However, this awe-inspiring body of water is facing many challenges that might change its future. In this article, we will explore the Great Salt Lake’s significance, the threats it currently faces, and the potential consequences for its delicate ecosystem.
Overview of the Great Salt Lake
A Natural Wonder
The Great Salt Lake is the largest saltwater lake in the Western Hemisphere, covering an area of approximately 1,700 square miles. Its saline waters make it three to five times saltier than the ocean, giving it a unique character and attracting millions of visitors each year.
Biodiversity and Importance
The lake provides a crucial habitat for an array of plants, birds, and other wildlife. It serves as a vital stopover for migratory birds traveling along the Pacific Flyway and supports large populations of shorebirds, waterfowl, and other avian species. The lake’s unique environment supports species that have adapted specifically to saline conditions, making it a hub of biodiversity.
Threats to the Great Salt Lake
One of the greatest challenges the Great Salt Lake faces is the reduction in freshwater inflows because of human water diversions. They have diverted streams and rivers that once fed the lake for agriculture, industrial use, and domestic consumption. This reduction in freshwater inflows disrupts the delicate balance of the lake’s ecosystem.
Drought and Climate Change
The Great Salt Lake is also heavily impacted by drought and climate change. Rising temperatures and changing precipitation patterns contribute to the lake’s shrinking water levels, exacerbating the salinity level and threatening both aquatic organisms and the surrounding wetlands.
Pollution and Nutrient Imbalance
Human activities in the watershed, such as urbanization and industrialization, have led to increased pollution and nutrient imbalances in the Great Salt Lake. Runoff containing chemicals, fertilizers, and harmful substances flows into the lake, causing algal blooms and degrading water quality. These factors can disrupt the delicate balance of the lake’s fragile ecosystem.
Invasive species pose a significant threat to the Great Salt Lake’s native flora and fauna. Species like carp and quagga mussels out-compete native species, disrupt food chains, and alter the lake’s ecological dynamics. These invasions have the potential to cause irreversible damage to the lake’s biodiversity.
Consequences for the Ecosystem
Bird Population Decline
With the potential decline in freshwater inflows and shrinking wetland habitats, the Great Salt Lake’s bird population is facing a serious threat. Migratory birds that rely on the lake’s resources for nesting and feeding may experience a decline in numbers or even face local extinction.
Loss of Biodiversity
The disruption of the Great Salt Lake’s delicate ecosystem could lead to the loss of unique species that have adapted to its saline conditions. As invasive species thrive and native species struggle, the biodiversity of the lake may be severely diminished.
The Great Salt Lake also plays a significant role in Utah’s economy. The lake supports recreational activities such as boating, birdwatching, and salt harvesting. The decline in the lake’s health and biodiversity could have adverse economic consequences for the local communities and businesses that depend on its resources.

The Great Salt Lake and its intricate web of life are facing an uncertain future. The combination of water diversions, drought, pollution, and invasive species poses significant challenges to this unique ecosystem. If we cannot address these issues and protect the lake, we risk losing not only a magnificent natural wonder but also vital habitats and a crucial stopover for migratory birds.
1. Q: What causes the Great Salt Lake’s high salinity levels?
The evaporation of water primarily caused – A: The lake’s high salinity levels, leaving behind dissolved salts.
2. Q: How does algae affect the Great Salt Lake?
A: Algal blooms caused by pollution and nutrient imbalances can deplete oxygen levels in the lake, leading to fish kills and negatively impacting other aquatic organisms.
3. Q: Are there any conservation efforts to protect the Great Salt Lake?
A: Yes, there are ongoing conservation efforts, including habitat restoration projects, water management strategies, and awareness campaigns aimed at preserving the lake’s ecological health.
4. Q: Can the Great Salt Lake recover from the current threats it faces?
A: While the challenges are significant, with proper conservation measures and collaborative efforts, there is hope for the recovery and protection of the Great Salt Lake’s ecosystem.
5. Q: What can individuals do to help protect the Great Salt Lake?
A: Individuals can contribute by conserving water, advocating for sustainable water management practices, supporting local conservation organizations, and raising awareness about the lake’s importance.
