Lake Tahoe weather: Central Sierra Snow Lab on Donner Summit experienced driest summer on record
LAKE TAHOE — UC Berkeley’s Central Sierra Snow Laboratory at Donner Summit experienced its driest summer on record this year.
Central Sierra Snow Laboratory, located at 6,900 feet, reported that this past summer had the least amount of precipitation the area has experienced since 1946—the year the lab was constructed.
The dry streak lasted from June 19 to Sept. 21.
“The rainfall on Sept. 22 ended a record 95 days without measurable precipitation here at the Snow Lab,” the lab posted on its Facebook page.
“This spanned the entire summer season and is the driest stretch ever recorded at our station. A few seconds of rain sprinkles were observed on August 18 and September 13, but fell far below the measurement resolution (0.25 mm) of our rain gauges.”
Lake Tahoe fell below its natural rim this summer on Sept. 12 after 165 days above the natural rim in 2016.
In 2015, Lake Tahoe was only above its natural rim for five days.
The Central Sierra Snow Laboratory is a research field station of UC Berkeley specializing in snow physics, snow hydrology, meteorology, climatology and instrument design.
