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.

Lake Levels Due to its shallowness (an average of 14 feet deep and a maximum of 35 feet deep), the water level can fall dramatically during dry years and rise during wet years. When snowpack melts in the spring, the lake usually rises about 2 feet. However, record snowpack in 2023 triggered a rise of 5.5 feet!
