The Mount Rose ski area, at 8,900 feet in the Sierra Nevada near Lake Tahoe, had 116 inches of snow Tuesday, with almost 3 feet freshly fallen since the day before Christmas.
The UC Berkeley Central California Snow Lab at Donner Summit on Tuesday morning reported more than 8 inches of snow in the previous 24 hours, bringing the total for December to 202 inches, the third snowiest month on record since 1970.
Lake Tahoe’s water level has dropped so low that water is no longer flowing into the Truckee River and salmon aren’t expected to spawn in a major tributary this year.
Some boat ramps and docks are hundreds of feet from the water line, and clumps of stringy algae have been washing up on beaches, said Geoffrey Schladow, director of the UC Davis Tahoe Environmental Research Center.
Lake Tahoe’s water level dropped to a four-year low on Tuesday as gusty winds and the impacts of California’s devastating drought hit the popular tourist destination.
After days of high winds increased evaporation rates, water levels fell to the basin’s natural rim for the first time since 2017, the end of the state’s last drought. The lake normally sits above the rim, which allows for water to flow into the Truckee River. Levels will probably continue to drop, receding below the rim this week, sooner than expected.
When Gov. Gavin Newsom asked Californians to voluntarily conserve water last week as he stood in front of the retreating shoreline at Lopez Lake in San Luis Obispo County, some must have had déjà vu.
It was only six years ago when former Gov. Jerry Brown stood in a field near Lake Tahoe that was bereft of normally plentiful snow and called for water restrictions amid the state’s punishing years-long drought.
Tiny specks of degraded plastics have been documented in the snowpack around Lake Tahoe — and in the lake itself. They have been found in the Las Vegas Wash. The phenomenon is not unique to Nevada. Microplastics, the end product of our plastic consumption, have been found in ecosystems across the world, even in remote areas.
Microplastics are small — less than 5 millimeters — but they are not uniform. They can have different shapes and vary in size. Microplastics from clothing can appear as synthetic fibers, whereas degraded plastic from bags or water bottles might take on a different composition.
Encouraged by three years of experimentation, scientists at Lake Tahoe plan to expand the use of ultraviolet light to kill algae and other invasive plants that eat away at the clarity of the mountain water.
Researchers at the University of Nevada, Reno are monitoring the project and collecting data to study the effects of the ultraviolet-C light treatments. It’s the newest tool in a two-decade effort to restore the once-pristine waters in the lake straddling the California-Nevada line.
Lake Tahoe’s famed clarity has long been used to gauge the health and changing conditions of Big Blue. Unlike in recent years when researchers were able to point to a dominant factor affecting lake clarity like drought or higher-than-average precipitation, 2019 saw a range of influences on Tahoe, including lake mixing for the first time in several years, sediment, algae, and climate warming.
California mountains are blanketed in snow and much of the state has had plenty of rain in a remarkable March turnabout from the extremely dry first two months of the year.
The most recent statewide storm started during the weekend and, despite diminishing, snow snowfall and showers were still occurring here and there.
In the Sierra Nevada, Homewood Mountain Resort on the west shore of Lake Tahoe reported late Tuesday a storm total of 114 inches (289.5 centimeters) of snow at its summit and 74 inches (188 centimeters) at the base.
One storm does not make a “Miracle March” but what an impact the last few days have had on the Sierra snowpack.
Continuous snow at Lake Tahoe since Saturday morning has added 13% to the snowpack, according to Jeff Anderson, water supply specialist for the Natural Resources Conservation Service in Nevada.
“To gain back that amount this time of year is really hard,” Anderson told the Tribune.
All of those dry January days have taken a toll on California’s snowpack, but officials say it’s too early to worry about drought conditions.
Surveyors with the California Department of Water Resources trekked through a snow-covered field Thursday at the department’s Phillips station, above Lake Tahoe, to take the second seasonal measurement that serves as an important marker for the state’s water supply.
