‘Last nail in the coffin’: Utah’s Great Salt Lake on verge of collapse

It's lost 73% of its water and is unable to sustain some wildlife - and could soon negatively affect human health

Emergency measures are required to avert a catastrophe in Utah's Great Salt Lake, which has been drying up due to excessive water use, a new report warns. Within years, the lake's ecosystems could collapse and millions will be exposed to toxic dust contained within the drying lakebed, unless drastic steps are taken to cut water use.

A team of 32 scientists and conservationists caution that the lake could decline beyond recognition in just five years. Their warning is especially urgent amid a historic western megadrought fueled by global heating. To save the lake, the report suggests 30-50% reductions in water use may be required, to allow 2.5m acre-feet of water to flow from streams and rivers directly into the lake over the next two years.
