10/15/25 9:20am Update:
It's official! Our first measurable snowfall happened. We had 7.3" (18.5 cm) of #snow accumulation at our measurement this morning.

It looks like we're done with snow for at least the next 10 days but we'll be watching the forecast excitedly.

Not enough #snow for a measurement this morning because we only measure accumulation greater than 0.5 cm (0.2"). Something tells us we'll have enough within the next 24 hours though...

👀 Is it happening? It might be happening. We'll be keeping an eye on the model runs but early next week is looking pretty good... ❄️❄️❄️

No snow yet but plenty of rain over the last 24 hours, which is a great start to the 2026 water year that began yesterday.

These early rain storms help prime our soil and keep it moist meaning less water from our snow has to do that job later.

Ah yes, summertime. Long hours of sunlight, days at the lake, and... SNOW?!

Yes, snow. Currently at the lab we have a mix of #snow and #graupel coming down. Nothing says summer serenity like a blanket of white!

It's not over yet! We've been getting snow all day and it has led to some wonderful spring conditions ❄️❄️❄️

#Snow started shortly after midnight and we have accumulated 4.5" (11.5 cm) so far with light to moderate rates.

We expect more snow through tomorrow with the heaviest rates being overnight tonight and another 5-10" at the lab.

There are over 250 snow survey sites in California where crews take manual measurements with hollow tubes, known as Federal Samplers, once a month from Feb to May!

This video is from late May when we did the Onion Creek in the American River Basin April 1 measurement.
