California Sees Snowpack Trifecta: What This Means
What a difference three years of cold, wet weather makes for the State of California — and experts are breathing a sigh of relief, at least for now.

What Could Future Colorado River Water Cuts Look Like? States Look to This Year’s Weak Snowpack to Find Out.
If any of the Colorado River management options were used to manage this year’s sub-par snowpack, Arizona, California and Nevada would be forced to slash 17% to 43% of their legal share. Coloradans would be focused on voluntary conservation.
What Does Our Water Picture Look Like After This Winter?: ‘This Year is a Lesson’
April 1 marks an important milestone for snowpacks and water supply forecasts as the date basin snowpacks typically reach a peak before melting. However, a wave of warm temperatures late March started the melt early, adding a caveat to April 1 measurements.
It’s Spring, but the Sierra Are Getting Slammed by Another Round of Snow
Significant snow falling in the Sierra Nevada over the next few days could be the region’s last big snow dump of the season, showcasing a dramatic rebound for the snowpack that provides a significant portion of California’s water reserves through the rest of the year.
California Snowpack is Near-Average — What Does This Mean for Water Supplies?
Despite some heavy rainstorms and squalls of snow in recent months, the Sierra Nevada snowpack today stands at 90% of average, according to state officials.
This year’s measurements mark the first below-average snowpack since 2022, when it dropped to a dismal 38% of the historical average.
California Reservoir Water Levels in Trouble After Unusually Dry January
California requires “several more storms” to make up for an unusually dry January that has plagued the southern half of the state, according to State Climatologist Michael Anderson.
Local Media Turn To Water Authority at Start of Dry Year
As San Diego enters the driest start to the water year since record keeping began in 1860, the San Diego County Water Authority has the reliable water supplies needed by the region for 2025 and beyond.
“We’ve been preparing for over three decades to have reliable water supplies, whether we’re in a drought or whether we have a wet year,” Water Authority Senior Water Resource Specialist Efren Lopez told CBS 8. “We have a lot of emergency storage in case there’s a disruption to our system.”
With coverage from CBS, KPBS and KUSI/Fox 5, the Water Authority has been informing and updating the public at every available opportunity.
The City of San Diego recorded only 0.14 inches of rain since Oct. 1, when typically it would have received between three and four inches.
While the lack of rain negatively impacts San Diego County’s flora and fauna — including increasing fire risk during the Santa Ana windstorms — the San Diego region doesn’t depend on local rainfall to supply the water that powers our economy and sustains our quality of life. Instead, the region uses a combination of desalinated seawater, conserved water from the Colorado River, recycled water, and runoff from the Sierra.
“San Diegans don’t need to worry about any water restrictions or any conservation mandates — we have plenty of water,” Lopez said.
Meanwhile, Northern California has been relatively wet. That means the state’s six major reservoirs are at 121% of their historical average levels at the beginning of 2025, slightly better than the same time last year. Additionally, the statewide snowpack is 115% of its historical average.
Precipitation over the next few months will be key to determining the state’s overall water supply for 2025. Regardless, the San Diego region has sufficient water for the foreseeable future.
