The UC Berkeley Central Sierra Snow Lab announced Monday a “NEW DECEMBER RECORD of 193.7 inches, which is more than 16 feet, and a prediction of breaking the 200 inch mark today.
NEW DECEMBER RECORD: 193.7"
With a 24 hour official #snow total of 38.9" at the lab, we have smashed the previous record of 179" of snow in December set in 1970!

“With a 24 hour official #snow total of 38.9″ at the lab, we have smashed the previous record of 179″ of snow in December set in 1970! Snow rates are still heavy and we could even break the 200″ mark today!
Located in a house at Donner Pass in the Sierra Nevada, the UC Berkeley Central Sierra Snow Laboratory “is a research field station of UC Berkeley specializing in snow physics, snow hydrology, meteorology, climatology, and instrument design,” according to their website. “Built in 1946 by the (then) U.S. Weather Bureau and Army Corps of Engineers, it is now managed by UC Berkeley.”
The UC Berkeley Central Sierra Snow Laboratory is one of the best instrumented snow study sites in the world
Harkening back to the amazing winter of 2017, in addition to the 38.9 inches in 24 hours of snow, the snow lab reports 67.9 inches of snow in 48-Hours of Snowfall, and 109.5 inches in 7 days.
In Sacramento Monday mid-day it hailed. Brrrrrrr. And we are looking at more freezing temperatures this week.
The California Highway Patrol reported road closures:
- I-80 CLOSED from Applegate to the Nevada Stateline.
- SR-89 Closed from Tahoe City to Squaw Valley Rd. due to an avalanche.
- SR-267 CLOSED from Northstar to Kings Bings Beach.
- SR-89 CLOSED from Truckee to Sierraville.
- SR-89 CLOSED from Bliss State Park to Eagle Point Campground
- US 50 CLOSED from Placerville to Myers.
The snow lab reported this Sunday:
Officially, 29" (~74 cm) of #snow in the last 24 hours at the lab. That takes our 7 day total to 70.6" (~179 cm) and December grand total to 155".

The UC Berkeley Central Sierra Snow Laboratory has been recording and reporting a consistent record of precipitation, snowfall, snow depth, and air temperature for the periods of 1946-1952 and 1957-present.
“The snow lab is also a primary collaborator and partner of the California Department of Water Resources (DWR) participating in the Cooperative Snow Surveys program, testing new instrumentation and infrastructure, and taking an active role in the DWR Data Acquisition Round Table (DART) program that focuses on bridging gaps from research to operations and standardizing snowpack measurements in California.”
Is the drought over?
As our favorite California water guru says, “The storm door has been kicked wide open! It looks like we’ll be having a white New Year too!!” reports Kristi Diener who founded and populates “The CA Water For Food and People Movement” on Facebook.
“This is the forecast for Shasta Lake. Shasta Reservoir is our state’s largest, and the beginning of our federal water that makes up the Central Valley Project. Its water is primarily used to grow the food that feeds America. There’s a reason why ‘Central Valley’ is in its name! It is managed by the U.S. Bureau of Reclamation.”
“In order for this water to reach our most productive and efficient farmland on the planet, it has to be released, and pumped when it reaches the south end of the Delta. From there it flows farther south until it reaches San Luis Reservoir where it is stored until it is needed.”
“Radical environmental policies have been put into place to keep water behind Shasta Dam during the summer time when it is critical for irrigation. The idea is to keep water deeper and colder so it can be released to cool off summer rivers later on, to help salmon spawn (which never works). Once water is let go, it has to be recaptured through pumping in order to make it to San Luis Reservoir and on to farms. But pumping is constantly throttled back instead resulting in the majority of this water free flowing into the Pacific Ocean, and never reaching food growers.”
“Endangered salmon have never recovered, been upgraded, or even improved by these policies.”
Fortunately, according to US StormWatch, “The snow is far from over for the Sierra Nevada, with the NWS Blend of Models predicting up to another 120 inches of snow (10 feet) to fall near Donner Summit in the next 3 days. @UCB_CSSL stands a good chance at smashing its all-time December snowfall record.”
