Watershed Symposium 2024

Summary:
How much water is Utah actually delivering to the imperiled Great Salt Lake? Are we heading toward a healthy Lake or costly mitigation? In this workshop, we explore a new report showcasing sobering findings exploring the consequences drying up the Great Salt Lake could have on Wasatch Front residents’ health and the state’s pocketbook.

Full Abstract:
If the Great Salt Lake is in peril, Utah is in peril. Great Salt Lake water levels are on a long-term decline – due to decades of upstream water diversions and climate change-driven aridification in the basin – exposing a vast expanse of dry lakebed that contains a number of toxic components. This creates a looming public health and economic crisis for residents of Northern Utah and the Wasatch Front. What are the financial and public health impacts to the millions of Utahns living adjacent to the Lake if we fail to deliver enough water to address current lakebed exposure issues and prevent continuing decline? In this session we will explore findings from a year of research that has culminated in a revelatory new report showcasing sobering findings concerning the consequences that drying up the Great Salt Lake could have on the health of Wasatch Front residents and the costly mitigation measures that could be required to suppress dust if Utah doesn’t succeed in raising Lake levels. We will present findings from what is, to our knowledge, the largest and most comprehensive review of the medical science of public health impacts from Great Salt Lake lakebed exposure. We will summarize what hundreds of papers show are the many and serious health implications associated with exposure to lakebed dust, discuss the possible presence of overlooked toxins in Great Salt Lake dust and their likely impact, and compare this emerging health emergency to that of other desiccated lakes around the world. In an analysis of efforts to deliver water to the Great Salt Lake, we will explore how effective Utah has been in meeting targets to deliver an additional 500,000 to 1 million acre feet of wet water each year to the Lake – the amounts needed to raise the Lake to a minimum healthy level and prevent catastrophic dust storms. Finally, we will examine whether we are headed toward a future of mitigation, like Owens Lake, and provide an updated and more detailed estimate of the costs associated with keeping dust from a desiccated Great Salt Lake on the ground.
