When California water officials assess the drought, the first place they look is the northern Sierra Nevada mountains.

Rain and snowmelt from the area feed into a complex system of rivers, canals and reservoirs that send water across the state. And by almost all measures, the drought picture in Northern California has dramatically improved over the last two months, as a series of storms have helped replenish the state’s two major water projects. So far this season, rain levels in the northern Sierra are 180% of average, with 23.5 inches of rain falling — and more on the way this week.

 But the story is more grim in Southern California, which remains historically dry. Now water officials must figure out how to deal with the disparity and its implications for managing the drought. While Southern California still gets some water from the Sierra, about 50% of its supply comes from local sources such as groundwater and reservoirs.

“California is a big place. It has different droughts in different parts,” said Jay Lund, a professor of civil and environmental engineering at UC Davis who studies water in California. “We certainly saw that last year … and we’re likely to see that again.”

Another big storm moving into California on Thursday is expected to dump large amounts of rain and snow in the north and considerably smaller amounts in Southern California.

Los Angeles marked a sober milestone earlier this year, when the National Weather Service announced that the last five years were the driest ever documented in downtown L.A. since official record keeping began almost 140 years ago. Precipitation during that period totaled just 38.79 inches — roughly half of normal.

Forecasters had predicted a wet 2016 fueled by El Niño, but the big storms never materialized. Federal climate scientists declared La Niña conditions last month, which they said will likely keep Southern California dry again this winter.

Northern California typically gets more rain than Southern California does, and the state’s water system is designed with that in mind; it moves water from the Sierra into cities and farms to the south.

But Lund said that even as conditions have gotten wetter, the state has struggled to move surplus water south across the delta. As a result, the benefits have been limited.

The sixth year of California’s drought could hardly have gotten off to a better start in Northern California. In October, when the water year began, the northern Sierra got more than four times its average amount of precipitation for the month.

As recently as last week, the northern Sierra got another 8 inches of precipitation, said Idamis Del Valle, a meteorologist with the National Weather Service office in Sacramento.

Forecasters say two more storm systems — the second of which will strike Los Angeles — will collectively dump as many as 9 additional inches of rain on the area by Friday.

“Here in Northern California, there has been some improvement,” Del Valle acknowledged.

The recent rains were enough to force federal officials to begin releasing water from Folsom Lake to protect against flooding for the first time since March, said Louis Moore, a spokesman for the Bureau of Reclamation, which manages the reservoir. Since the beginning of December, Folsom has risen more than 20 feet — an increase of about 55 billion gallons.

As of last week, the U.S. Drought Monitor reported that drought conditions no longer apply to about 27% of California; it should come as no surprise that all the areas where the drought has relented are located in the upper reaches of the state.

Meanwhile, a vast swath of Southern and Central California — from Orange County to Tulare County — remains mired in “exceptional” drought conditions, according to federal officials.

The so-called Key Well, which measures groundwater levels in the San Gabriel Basin, hit a historic low in October. Meanwhile, Lake Perris in Riverside County is holding less than half the amount of water it usually does at this time of year. Castaic Lake in Los Angeles County is faring only marginally better, filled to only 74% of its normal levels.

Along the Central Coast, Lake Cachuma is filled to only about 7% of its capacity, which has prompted Santa Barbara city officials to impose a ban on lawn watering, effective next year. Further inland, the Tulare Basin has received only about four inches of rain so far this water year — about 64% of average.

“We have some systems that are back in their normal operating range,” said State Climatologist Mike Anderson, “and we have other areas that are in the thick of things as much as they’ve ever been.”

Thursday’s winter storm is expected to cover the entirely of California, Anderson said. But it could be particularly helpful to the southern parts of the state that need the rain the most.

Since Oct. 1, Los Angeles County has gotten about 70% to 90% of average rainfall, said Jayme Laber, a hydrologist in the National Weather Service’s Oxnard office. For example, about 1.4 inches of precipitation has fallen on downtown L.A. since that time — about an inch less than normal.

Thursday’s storm alone could add more than an inch of rain to downtown and fill the gap, Laber said. But it is unlikely to generate the type of torrential rain that causes flooding.

WATERFEST 2016 TO HONOR THREE LEADERS AS POLICYMAKERS OF THE YEAR – Upper San Gabriel Valley Municipal Water District Hosts Annual WaterFest

MONROVIA, CA – Upper San Gabriel Valley Municipal Water District (Upper District) is partnering with the Los Angeles County Department of Parks and Recreation to host WaterFest 2016. WaterFest is a community outreach event focused on educating residents on water conservation and environmental stewardship.

Upper District will honor three policymakers who have made a significant impact on water-related policy and legislation. Senator Bob Huff, Senator Carol Liu and Los Angeles County Supervisor Michael Antonovich will receive the San Gabriel Valley Water Smart Award for their focus on water sustainability and support of water conservation projects.

“Honoring these elected officials is our way of thanking them for leadership and efforts in developing sound water policy for the San Gabriel Valley,” said Upper District Board President Bryan Urias. “WaterFest is the perfect community event and we can’t think of a better time to express our appreciation for these policymakers that have dedicated many years of service to their communities.”

Upper District is also honoring Miller Coors with the San Gabriel Valley Water Smart Business of the Year award. Based in Irwindale, the Miller Coors facility has made significant strides in implementing water conservation best practices, such as turf removal, that will significantly reduce their outdoor landscaping water usage.

Over 50 exhibitor booths focused on water sustainability and environmental stewardship will be set up to educate and entertain residents of all ages. There will be food trucks, raffle prizes, activities and giveaways. Waterfest will also have cheer competition for the LA County Parks and Recreation Department’s cheerleading teams. Over 500 cheerleaders will participate and each team will have one minute to perform a water conservation-themed cheer. The top three teams will receive a 2016 WaterFest trophy.

The event will be held on Saturday, October 15th from 10am – 2pm at Arcadia County Park, located at 405 S. Santa Anita Ave. Arcadia.

Upper District’s mission is to provide a reliable, sustainable, diversified and affordable portfolio of high quality water supplies to the San Gabriel Valley; including water conservation, recycled water, storm water capture, storage, water transfers and imported water. Upper District services nearly one million people in its 144 square mile service territory. Governed by a five member elected board of directors, Upper District is a member agency of the Metropolitan Water District of Southern California. Annually, more than 78 billion gallons of water is used in Upper District’s service area.
