The verdict is in on the main source of California's water supply and the news is not good. The official snowpack measurements taken in the Sierra showed the second lowest amount of snow ever recorded. We take a look at the numbers and what it could mean for residents.

Sierra County

Recent official measurements in the Sierra Nevada indicate the second lowest snowpack ever recorded, with some stations reporting zero measurable snow. While California's water supply remains stable due to previous wet years, water officials warn that continued low snowpack could lead to drought conditions statewide.

The snowpack is currently at just 18% of the average, with snowmelt occurring over a month earlier than usual and most precipitation falling as rain. Despite these concerning trends, no emergency or drought has been declared yet, but authorities urge residents to remain aware as the situation develops.

Sierra snow totals raise concern

Well, the verdict it is in on the main source of California's water supply, and the news is not good. Official snowpack measurements taken just today in the Sierra showed the second lowest amount of snow ever recorded. KTVU is Mark Sayre live in San Jose tonight with a look at the numbers and what it could mean for residents. Hi, Mark. Well, Greg, Heather, what it means for right now is just be aware. Both statewide and local water officials say the water supply is stable for now. But if the trends identified today in the Sierra Nevada continue, California could be headed toward another drought at Phillip Station. Just off of Highway 50 in El Dorado County, the California Department of Water Resources took its critical April snow survey. The problem is there was no snow. Official measurements recorded zero snow and zero water content in that snow. We measure today, but there was actually no measurable snow. So our instruments that we use aren't able to pick up any snow. So we're calling today's measurement zero. The levels recorded were the second lowest in history, trailing only 2015. The only reason this year was not the worst is because there actually was a trace of snow visible, but it was not enough to measure. Normally, we'd be standing right here if we had an average year. This was obviously a below average year. No matter where you live in the Bay Area, your water supply to some extent relies on snowpack in the Sierra Nevada, San Francisco and parts of the peninsula rely on the Hetch Hetchy system, while most of the east and South Bay rely on a combination of federal and state sources and reservoirs like Lake Shasta and like Oroville. All of those water systems rely on snowpack to keep them for valley water, serving about two million residents in Santa Clara County. Baker says several wet years have allowed the agency to fill its reservoirs and replenish its groundwater supplies, which can be used if other sources are reduced. So basically what we're looking at right now is that, you know, is that this is a year where we're doing fine. But if this continues, these are how droughts begin statewide. The snowpack number sits at just 18%. Another concern. Water officials say the snow melt is occurring more than a month ahead of normal. Most of our precipitation, which is just below average this year, came as rain, and it's the combination of rain and limited snow and warmer temperatures in March that are setting us up for what will be a challenging year for water management in the state. Now, in the key October to February time frame, that's when the hope is the snow accumulates high up in the Sierras and and stays there for a while and melts a little bit later in the season. The average low temperatures that they're seeing those low temperatures are not getting very low. In fact, in that time period, just in these past few months, they're the highest low temperatures they have ever recorded over the season, and those records go back to 18 96. So obviously there's a reason why there is concern, but there is no emergency just yet. No drought just yet. That's the latest from the snow survey report today reporting live in San Jose. I'm Mark Sayer KTVU Fox two news. Heather Greg. Yeah, we just need to be aware because right now things just not looking very good, Mark. Thank you. All right now.
