Despite a Wet El Niño Forecast for Southern Nevada, Lake Mead Unlikely to See Water Level Rise

The National Oceanic and Atmospheric Administration is predicting higher-than-usual rainfall for parts of Nevada, California and Arizona this winter, but that rainfall isn’t expected to translate to gains in the water level at Lake Mead, regional climate experts said.

El Niño’s southern oscillation cycle began changing weather patterns this month and will continue through the winter to bring wetter conditions to the southern United States, said Jon Gottschalck, the operational prediction branch chief for the National Oceanic and Atmospheric Administration (NOAA).

Since almost completely running out of water in 2015, and again in 2021, the City of Fort Bragg is working to make sure it stays ahead of any future droughts by investing in desalination.

“We stopped allowing people to wash dishes and had them use paper products and things like that, just disposable plates and things like that. So it was very serious at that time,” Director of Public Works for the City of Fort Bragg John Smith said.
