How an international collaboration is helping Tahoe get ahead of climate impacts

International Collaboration Advances Lake Tahoe Climate Research

An international partnership with Italian scientists is preparing Lake Tahoe for significant environmental changes expected by the end of the 21st century. Researchers, including Dr. Sudeep Chandra, a limnology professor at the University of Nevada, Reno, predict that Lake Tahoe will cease to mix fully between 2070 and 2100 due to altering climate, precipitation, and wind patterns.

Importance of Lake Mixing

Mixing is a natural process that distributes oxygen and nutrients throughout a lake’s layers. Without this cyclical mixing, lake ecosystems face new management challenges and ecological risks.

Lessons from Italian Lakes

Italian lakes such as Maggiore and Iseo provide a case study, having stopped mixing around 2006 due to warmer winters that prevent surface water from cooling sufficiently to blend with deeper water. Researchers Barbara Leoni and Veronica Nava have studied these changes extensively.

“We’re trying to get ahead of this issue that will arise as the climate changes so managers can create progressive policies which manage for a new lake future,” Chandra said during fieldwork at Tahoe with Leoni and Nava.

Because these Italian lakes share similar structures with Tahoe, they offer valuable insights and research lessons to help predict and manage Tahoe’s future conditions.

Ongoing Research and Future Outlook

By the time Lake Tahoe stops mixing, scientists aim to have a wealth of research and knowledge gathered from the Italian experience to guide sustainable lake management.

Author’s summary: International research collaboration is equipping Lake Tahoe with vital knowledge to tackle future climate-driven changes in lake mixing, ensuring informed management strategies.
