The Great Salt Lake and its decreasing water levels

The Great Salt Lake is one of Utah’s most iconic natural landmarks, but in recent years its shrinking shoreline has become a growing concern. Once the largest saltwater lake in the Western Hemisphere, the lake has reached record-low levels due to drought, climate change, and increasing water diversion. Let’s talk about what is going on.

Why the Great Salt Lake is shrinking

Several factors are driving the decrease in water levels:

Extended drought – Utah’s ongoing dry conditions mean less snowpack runoff feeding the lake.

Water diversion – Growing urban development and agriculture pull water from rivers and streams that flow into the lake.

Climate change – Rising temperatures increase evaporation, accelerating water loss.

Impacts of a shrinking lake

The consequences of a receding Great Salt Lake are widespread:

Environmental – Wetlands are disappearing, threatening millions of migratory birds and other wildlife.

Health – Exposed lakebed dust contains toxic minerals that can affect air quality in Salt Lake City and surrounding communities.

Economy – Industries like mineral extraction, brine shrimp harvesting, and recreation are all at risk as the lake continues to decline.

What’s being done

Utah lawmakers, scientists, and community groups are pushing for water conservation, river restoration, and policies that prioritize the lake’s survival. Some solutions include redirecting water flows, reducing urban consumption, and raising public awareness about the crisis.

Why it matters

The Great Salt Lake isn’t just a local treasure — it’s a critical ecosystem that supports wildlife, protects air quality, and shapes Utah’s culture and economy. Preserving it requires collective action and long-term planning.
