Episode Details:

• Title: PREVIEW - The Friday Edition: What Happened to: The Great Salt Lake's Collapse
• Host: Isaac Saul
• Release Date: August 1, 2025

Overview: In this detailed preview of Tangle's latest Friday Edition, senior editor Will Kaback delves into the environmental saga surrounding Utah's Great Salt Lake. The episode explores the initial alarming predictions of the lake's imminent collapse, the subsequent actions taken by various stakeholders, and the unexpected developments that have since emerged. Through expert interviews and thorough analysis, the episode examines whether the crisis was averted through concerted efforts or if flawed science and media communication played a role in the evolving situation.

1. Introduction to the Series and Episode ([01:46] - [07:25])

Will Kaback introduces the episode as the second installment in the "What Happened to Blank?" series, which revisits past environmental crises that captured public attention but lacked clear resolutions in the media. This episode focuses on the Great Salt Lake, aiming to uncover the truth behind its reported collapse.

Key Points:

• Purpose of the Series: To investigate past environmental stories that faded without clear outcomes.
• Focus on Great Salt Lake: Examining the predictions and actual developments over the past few years.

2. The 2023 Report and Initial Alarm ([07:25] - [08:38])

Kaback recounts the 2023 report by researchers and activists warning that the Great Salt Lake was losing water at an alarming rate, potentially disappearing within five years. The report sparked widespread media coverage and bipartisan legislative action.

Notable Quotes:

• Kaback: "Utah's Great Salt Lake was losing water so fast that it was on track to effectively disappear within five years." ([02:15])

Media Reaction:

• CNN: “Great Salt Lake will disappear in five years without massive emergency rescue, scientists say.”
• The Guardian: “Drying Great Salt Lake could expose millions to toxic arsenic-laced dust.”

Legislative Response:

• Utah Legislature proposed and passed nine out of fourteen bills aimed at water conservation and revitalizing the lake.
• Establishment of the Office of the Great Salt Lake Commissioner.

3. Developments Over Two and a Half Years ([08:38] - [16:23])

As the five-year mark approaches, initial optimism from the 2023 report is challenged by new developments. Contrary to predictions, the lake's water levels have stabilized and even risen slightly.

Key Developments:

• Governor Spencer Cox's Skepticism: In March 2024, Cox publicly dismissed the 2023 report as "laughable" ([04:10]).

  • Governor Cox: “It's a joke and everybody knows it's a joke. That's the doomerism that is terrible for people.” ([04:15])

• Increased Water Levels: Despite initial fears, the lake's water level in 2024 rose by three feet compared to two years prior.

Analysis of the Situation:

• Possible Reasons for Stabilization:
  • Increased snowfall in early 2023 provided a much-needed boost to the lake's water levels.
  • Improved water management and conservation efforts.

4. Understanding the Great Salt Lake's Unique Ecology ([08:38] - [16:23])

Kaback provides an in-depth look at what makes the Great Salt Lake unique, emphasizing its saline nature and terminal basin characteristics. The division into North and South Arms by the Union Pacific railroad causeway has led to distinct ecological environments within the lake.

Key Points:

• Salinity Levels: Up to nine times saltier than the ocean in certain areas.
• Terminal Lake: No outflow points; water remains, increasing salinity as it evaporates.
• Historical Context: Remnant of Lake Bonneville from 30,000 to 13,000 years ago.

Ecological Significance:

• Economic Contribution: Approximately $1.9 billion annually, supporting 7,000 jobs.
• Biodiversity: Over 10 million birds from 338 species utilize the lake during migrations.
• Wetlands Support: Maintains 80% of Utah's valuable wetlands.

Expert Insights:

• Bonnie Baxter ([12:30]): “The brine shrimp and brine flies won't be able to live here, and they feed the 10 million birds that visit the lake every year.” ([12:45])
• Ben Abbott: Highlighted the urgency of the 2023 report and the ethical responsibility to communicate specific threats.

5. Causes of Decline: Human Activity and Climate Change ([16:23] - [18:31])

The report identified water diversion for agriculture and population growth as primary drivers of the lake's decline, with climate change contributing significantly as well.

Water Use:

• Agricultural Withdrawal: 2.1 million acre-feet annually, with 67% used for crops like alfalfa and hay.
• Population Growth: Projected 14% increase in Utah's population over the next decade, exacerbating water demand.

Climate Change Impact:

• Contributions to Decline: Approximately 9% attributed to increased temperatures and reduced runoff.
• Ben Abbott on Climate Change: “The specificity was really important. I would not feel ethical as a researcher if we hadn't been as clear as we were.” ([10:50])

Environmental Consequences:

• Increased Emissions: Drying lakebed emits significant CO2 and methane, contributing to greenhouse gas levels.

  • Soren Brothers: “As the Great Salt Lake dried, it exposed sediment that was emitting carbon dioxide and methane.” ([13:30])

• Toxic Dust Risks: Exposed sediments release arsenic-laced dust, posing severe health risks.

  • Carrie Kelly: “We saw elevated levels of copper and manganese and iron. When they get into your lungs they can cause a lot of irritation and damage.” ([14:15])

6. Current Status and Future Outlook ([18:31] - End)

Kaback assesses the current status of the Great Salt Lake, acknowledging the complexities and uncertainties that remain.

Status Update:

• Water Levels: Stabilized due to record snowfall in early 2023, which significantly increased water inflow.
• Scientific Consensus: Despite increased water levels, experts remain cautious about future sustainability.
  • Ben Abbott: Emphasized that the lake was still on a precarious path despite temporary improvements.

Future Projections:

• Ongoing Challenges: Continued water diversion, population growth, and climate change continue to threaten the lake's health.
• Need for Persistent Efforts: Sustained conservation and adaptive management strategies are essential to ensure the lake's longevity.

Conclusion: The episode highlights the dynamic interplay between environmental science, policy action, and natural phenomena. While initial predictions of the Great Salt Lake's collapse have been mitigated by unforeseen factors like increased snowfall, the underlying issues of water management and climate change persist, necessitating ongoing vigilance and proactive measures.

Final Thoughts: Through expert interviews and comprehensive analysis, Tangle provides listeners with a nuanced understanding of the Great Salt Lake's environmental challenges, emphasizing the importance of accurate science communication and sustained collective action in addressing ecological crises.
