Topic: Central Valley

Overview

Central Valley

The Central Valley is a vital agricultural region that dominates the center of California, stretching 40-60 miles east to west and about 450 miles from north to south.  It covers 22,500 square miles, about 13.7% of California’s total land area.

Key watersheds are located here: The Sacramento Valley in the north, San Joaquin Valley and Tulare Basin to the south. In addition, the Sacramento and San Joaquin rivers drain their respective valleys and meet to form the Sacramento-San Joaquin Bay Delta, which flows to the Pacific Ocean via the San Francisco Bay.

On a small scale, aquifers — subsurface natural basins — have been recharged with flood waters from extreme storms for decades. Now, a new Department of Water Resources (DWR) assessment shows how Flood Managed Aquifer Recharge, or Flood-MAR, can help reduce flood risk and boost groundwater supplies across large areas of land. … In partnership with the Merced Irrigation District, Sustainable Conservation, and others, DWR experts analyzed how this would work in the Merced River —a 145-mile-long tributary of the San Joaquin River. The Merced River, which flows from the Sierra Nevada to the San Joaquin Valley, could be much more vulnerable to heavy flooding as storms intensify.

Blog: Conservation helps farms survive—and thrive—in drought

Healthy soil is a potent tool to combat the impacts of drought on farms and ranches. By using conservation practices that build healthy soil—like cover cropping, conservation tillage, and compost—growers increase the natural water storage potential of their land. Healthy soil captures more water when it rains and holds onto that water for future crop use, allowing farms with healthy soil to deliver stable yields, even in drought years.

Opinion: Food choices are the real drivers of water usage

960,000 acres of land in California are used to produce alfalfa, using 2 million gallons of water per acre, per year, all of which goes to feed livestock. What kind of livestock? Mostly dairy cows, of which there are 2.5 million in California alone. … It turns out, states [author Richard] Oppenlander, “60 to 70 percent of California water goes to livestock and crops to feed them.” …Once I learned that it takes 1,000 gallons of water to produce one gallon of milk, (raising the cow, growing grain for the cow, cleaning the cow) buying non-dairy milk sounds like a much wiser choice. Once I learned that it takes 2,400 gallons of water to produce one pound of meat, giving up meat altogether seems like the only choice.

After three years of drought, the massive state and federal water projects that serve California’s cities and farms have less water to distribute, forcing water managers to increasingly ration supplies. This year, squeezed extra tight by the prolonged drought conditions, both the state and federal water projects are expecting to deliver mere fractions of what cities and farms are asking for. … Everyone gets less water during a drought. But the breakdowns of the state and federal projects’ water allocations show some groups — particularly farmers who have longtime rights to divert water — faring better than others.

As New Deadline Looms, Groundwater Managers Rework ‘Incomplete’ Plans to Meet California’s Sustainability Goals
WESTERN WATER IN-DEPTH: More than half of the most critically overdrawn basins, mainly in the San Joaquin Valley, are racing against a July deadline to retool their plans and avoid state intervention

A field in Kern County is irrigated by sprinkler.Managers of California’s most overdrawn aquifers were given a monumental task under the state’s landmark Sustainable Groundwater Management Act: Craft viable, detailed plans on a 20-year timeline to bring their beleaguered basins into balance. It was a task that required more than 250 newly formed local groundwater agencies – many of them in the drought-stressed San Joaquin Valley – to set up shop, gather data, hear from the public and collaborate with neighbors on multiple complex plans, often covering just portions of a groundwater basin.

California Spent Decades Trying to Keep Central Valley Floods at Bay. Now It Looks to Welcome Them Back
WESTERN WATER IN-DEPTH: Floodplain restoration gets a policy and funding boost as interest grows in projects that bring multiple benefits to respond to climate change impacts

Land and waterway managers labored hard over the course of a century to control California’s unruly rivers by building dams and levees to slow and contain their water. Now, farmers, environmentalists and agencies are undoing some of that work as part of an accelerating campaign to restore the state’s major floodplains.

SIDEBAR: Creating A Floodplain Buffet for Salmon Smolts

Biologists have designed a variety of unique experiments in the past decade to demonstrate the benefits that floodplains provide for small fish. Tracking studies have used acoustic tags to show that chinook salmon smolts with access to inundated fields are more likely than their river-bound cohorts to reach the Pacific Ocean. This is because the richness of floodplains offers a vital buffet of nourishment on which young salmon can capitalize, supercharging their growth and leading to bigger, stronger smolts.

Wednesday Top of the Scroll: Red alert sounding on California drought, as farmers get less water

A government agency that controls much of California’s water supply released its initial allocation for 2021, and the numbers reinforced fears that the state is falling into another drought. The U.S. Bureau of Reclamation said Tuesday that most of the water agencies that rely on the Central Valley Project will get just 5% of their contract supply, a dismally low number. Although the figure could grow if California gets more rain and snow, the allocation comes amid fresh weather forecasts suggesting the dry winter is continuing. The National Weather Service says the Sacramento Valley will be warm and windy the next few days, with no rain in the forecast.

Nancy Vogel, director of the Governor’s Water Portfolio Program, highlights key points in the draft Water Resilience Portfolio last month for the Water Education Foundation's 2020 Water Leaders class. Shortly after taking office in 2019, Gov. Gavin Newsom called on state agencies to deliver a Water Resilience Portfolio to meet California’s urgent challenges — unsafe drinking water, flood and drought risks from a changing climate, severely depleted groundwater aquifers and native fish populations threatened with extinction.

Within days, he appointed Nancy Vogel, a former journalist and veteran water communicator, as director of the Governor’s Water Portfolio Program to help shepherd the monumental task of compiling all the information necessary for the portfolio. The three state agencies tasked with preparing the document delivered the draft Water Resilience Portfolio Jan. 3. The document, which Vogel said will help guide policy and investment decisions related to water resilience, is nearing the end of its comment period, which goes through Friday, Feb. 7.

Recharging Depleted Aquifers No Easy Task, But It’s Key To California’s Water Supply Future
WESTERN WATER NOTEBOOK: A UC Berkeley symposium explores approaches and challenges to managed aquifer recharge around the West

A water recharge basin in Southern California's Coachella Valley. To survive the next drought and meet the looming demands of the state’s groundwater sustainability law, California is going to have to put more water back in the ground. But as other Western states have found, recharging overpumped aquifers is no easy task.

Successfully recharging aquifers could bring multiple benefits for farms and wildlife and help restore the vital interconnection between groundwater and rivers or streams. As local areas around California draft their groundwater sustainability plans, though, landowners in the hardest hit regions of the state know they will have to reduce pumping to address the chronic overdraft in which millions of acre-feet more are withdrawn than are naturally recharged.

Salinity

Excess salinity poses a growing threat to food production, drinking water quality and public health. Salts increase the cost of urban drinking water and wastewater treatment, which are paid for by residents and businesses. Increasing salinity is likely the largest long-term chronic water quality impairment to surface and groundwater in California’s Central Valley.

With the dual threats of obsolete levees and anticipated rising sea levels, floodplains—low areas adjacent to waterways that flood during wet years—are increasingly at the forefront of many public policy and water issues in California.

Adding to the challenges, many floodplains have been heavily developed and are home to major cities such as Sacramento. Large parts of California’s valleys are historic floodplains as well.

This issue of Western Water examines the extent to which California faces a disaster equal to or greater than the New Orleans floods and the steps being taken to recognize and address the shortcomings of the flood control system in the Central Valley and the Delta, which is of critical importance because of its role in providing water to 22 million people. Complicating matters are the state’s skyrocketing pace of growth coupled with an inherently difficult process of obtaining secure, long-term funds for levee repairs and continued maintenance.
