Overview

Groundwater

Unlike California’s majestic rivers and massive dams and conveyance systems, groundwater is out of sight and underground, though no less plentiful. The state’s enormous cache of underground water is a great natural resource and has contributed to the state becoming the nation’s top agricultural producer and leader in high-tech industries.

Groundwater is also increasingly relied upon by growing cities and thirsty farms, and it plays an important role in the future sustainability of California’s overall water supply. In an average year, roughly 40 percent of California’s water supply comes from groundwater.

A new era of groundwater management began in 2014 with the Sustainable Groundwater Management Act, which requires local and regional agencies to develop and implement sustainable groundwater management plans with the state as the backstop.

State board to vote on reducing extraction fees for probationary basins

On the eve of its first subbasin probationary hearing, the state Water Resources Control Board announced it will vote on whether to reduce a controversial groundwater extraction fee.  The board will vote at its March 19 meeting on whether to cut the fee from $40 to $20-per-acre-foot for well owners in a subbasin placed on probation.  It will hold its first probationary hearing on the Tulare Lake subbasin, which covers Kings County, on April 16. Then the Tule subbasin, in the southern half of the valley portion of Tulare County, will come up for hearing Sept. 17. The extraction fee would only be charged if the Water Board had to step in and administer a subbasin in cases where it finds local groundwater agencies aren’t up to the job.

Thursday Top of the Scroll: New study – California’s farm belt sees thirstier crops, pressure on water supply

Climate change is driving up the thirst of crops significantly in California’s San Joaquin Valley, new research shows, adding to the critical water challenges faced by one of the world’s leading agricultural regions. The total water demand of orchards, vineyards and row crops in the area is up 4.4% over the past decade compared with the prior 30 years because of hotter, drier conditions, and it’s likely to continue growing, according to a federally funded study published this week. In 2021, the water demand of crops was up an astonishing 12.3%, the study shows. While the warming atmosphere has long been known to dry out plants and soil, the new research identifies the impact specific to the San Joaquin Valley.

States grapple with how to grow in drying West

Across the parched West, there are signs the region’s decades-long population and housing boom is confronting the realities of dwindling water supplies. These have come in recent months from court rulings and executive edicts alike, as states crack down on the potential for new users to draw from already oversubscribed aquifers and surface waters. The skeleton of a would-be subdivision outside Las Vegas illustrates the coming constraints, stymied by a lack of water to support the new community. Water shortages also forced difficult decisions in other places, such as new restrictions in the Phoenix suburbs and a Utah town that halted all new construction for more than two years until it could secure a new well.

SLO receives $6.6 million grant to clean up contaminated groundwater

The California State Water Resources Control Board issued a $6.6 million grant for a city of San Luis Obispo project intended to clean up contaminated groundwater. Presently, the city does not use groundwater for its drinking water supply. SLO’s potable water supply comes from Whale Rock Reservoir, Santa Margarita Lake and Nacimiento Reservoir.  City officials have sought to diversify the water supply in an attempt to achieve “greater drought and climate change resiliency.” Previously, contamination from tetrachloroethylene, or PCE, served as a barrier to doing so. PCE is a toxic chemical produced by dry cleaning and industrial activities, which took place in the city decades ago. The cleanup project will consist of the city building two new groundwater supply wells that are expected to be fully operation in 2026.

Tuesday Top of the Scroll: Second San Joaquin Valley groundwater subbasin recommended for state takeover

The Friant-Kern Canal was called out specifically as one of the reasons the state should take over pumping in the Tule groundwater subbasin in Tulare County. The recommendation was contained in a recently released staff report to the Water Resources Control Board. While the report stated groundwater management plans covering the subbasin didn’t adequately address subsidence and continued depletion of the aquifer and degradation of water quality in general, it also noted the significant harm to the Friant-Kern Canal, which brings water 152 miles south from Millerton Lake to Arvin. Excessive overpumping caused land beneath a 33-mile stretch of the Friant-Kern Canal to collapse, creating a sag that reduced the canal’s carrying capacity south of Pixley by 60%.

How you can help refill LA’s aquifers by capturing stormwater at home

Recently, we dove deep on how every time rain falls in Southern California, gigantic pieces of infrastructure come to life in an effort to sequester as much of the stormwater as possible. Water agencies implement dry wells, dams and spreading grounds the size of neighborhoods to give each drop a chance to percolate deep into the soil and refill our overdrawn reservoirs. The problem is we’ve all but run out of room for spreading grounds, and while the water agencies are implementing other options, you can make a difference at the household level as well. All you need is a shovel, some rocks and a tiny patch of land. The goal is simple: you want to slow down water and give it a chance to sink into the earth.

After years of rapid growth, California’s almond industry struggles amid low prices

For much of the last decade, almonds have been such a lucrative crop that growers and investment firms have poured money into planting new orchards across vast stretches of California farmland. Now, the almond boom has fizzled and the industry has entered a slump. Prices have dropped over the last several years, and the state’s total almond acreage has started to decrease as growers have begun to tear out orchards and plant other crops. … Over the last decade, the almond boom coincided with growing concerns about water in California. When growers and investment companies bought land and drilled wells to pump groundwater in the Central Valley, the expanding nut orchards locked in long-term water demands and added to the strains on the state’s declining aquifers. Wenger said he thinks it’s possible that if some of these orchards come out of production, groundwater levels could rise in places.

How a solar revolution in farming is depleting world’s groundwater

There is a solar-powered revolution going on in the fields of India. By 2026, more than 3 million farmers will be raising irrigation water from beneath their fields using solar-powered pumps. With effectively free water available in almost unlimited quantities to grow their crops, their lives could be transformed. Until the water runs out. The desert state of Rajasthan is the Indian pioneer and has more solar pumps than any other. Over the past decade, the government has given subsidized solar pumps to almost 100,000 farmers. Those pumps now water more than a million acres and have enabled agricultural water use to increase by more than a quarter. But as a result, water tables are falling rapidly. There is little rain to replace the water being pumped to the surface. In places, the underground rocks are now dry down to 400 feet below ground.

Auditor blasts Arizona Land Department over leases to Saudi-owned farm with low rent, no water rules

The company, Fondomonte, used the land — and the groundwater beneath it — to grow alfalfa for dairy cattle in the Middle East. State Auditor General Lindsey Perry says the Land Department’s practices for valuing the land it leases don’t align with what’s recommended. In addition, state law requires the department to conduct a mass appraisal of its properties at least once every 10 years to determine its agricultural rental rates. But the last one was done in 2005. This resulted in $3.4 million less in revenues going into the land trust that provides revenues for K-12 education and other beneficiaries.

Opinion: Reform water law to include the environment

Arizona officials are proud of their 1980 state water policy. The Arizona Groundwater Management Act (GMA), after many earlier attempts, was approved only after the federal government threatened to withhold funding for the Central Arizona Project (CAP) unless Arizona controlled groundwater pumping. Without the CAP, California would have claimed “our” Colorado River water and restricted future economic development in Arizona. The environment wasn’t at the negotiating table then, so our rivers were on the menu. The GMA managed groundwater only in limited areas and sacrificed some rivers. We have now seriously degraded five of Arizona’s major perennial rivers: the Colorado, Gila, Salt, Santa Cruz, and San Pedro. Additionally, future perennial flow in the upper Verde River is deeply threatened.

How much stormwater can we actually capture?

From January to February, Southern California went from quite dry to overwhelmingly wet, as a series of storms dropped more than a year’s worth of water in just a few weeks, loading up the L.A. River. Given that our dry months are coming up, just how much of that stormwater were we able to hold on to? And could we be doing better? The main way that we capture stormwater is by letting it soak into the Earth and travel through the soil into underground reservoirs. Back in the day, this would happen all across places like the L.A. Basin, but as we paved over much of the area, we lost much of our ability to sequester rainfall. That’s where spreading grounds, like those in the San Fernando Valley (seen below), come in.

All but one of the major reservoirs are storing in excess of 100% of their average, and five out of the 12 are nearing capacity, since they are over 75% full. Also, no part of the state is currently under drought conditions. But that doesn’t mean California no longer faces chronic water shortages. Droughts are becoming more common and more extreme as the climate crisis intensifies, and communities dependent on depleted underground aquifers and parched Colorado River supplies do not have enough water to meet the demands of their farms and cities. . … Last year’s Sierra Nevada snowpack tied with 1952 for the highest on record at the end of the snow season. So far this year, on Feb. 5, the snowpack was 72% of average for that date.

OpenET study helps water managers & farmers put NASA data to work

As the world looks for sustainable solutions, a system tapping into NASA satellite data for water management has passed a critical test. Called OpenET, the system uses an ensemble of six satellite-driven models that harness publicly available data from the Landsat program to calculate evapotranspiration (ET)—the movement of water vapor from soil and plant leaves into the atmosphere. OpenET does this on a field-level scale that is greatly improving the way farmers, ranchers, and water resource managers steward one of Earth’s most precious resources. Researchers have now conducted a large-scale analysis of how well OpenET is tracking evapotranspiration over crops and natural landscapes. The team compared OpenET data with measurements from 152 sites with ground-based instruments across the United States. In agricultural areas, OpenET calculated evapotranspiration with high accuracy, especially for annual crops such as wheat, corn, soy, and rice.

Farmers in Tulare County to test groundwater market they hope could help keep them in business and replenish the aquifer

How will selling groundwater help keep more groundwater in the San Joaquin Valley’s already critically overtapped aquifers? Water managers in the Kaweah subbasin in northwestern Tulare County hope to find out by having farmers tinker with a pilot groundwater market program. Kaweah farmers will be joining growers from subbasins up and down the San Joaquin Valley who’ve been looking at how water markets might help them maintain their businesses by using pumping allotments and groundwater credits as assets to trade or sell when water is tight.

New California Law Bolsters Groundwater Recharge as Strategic Defense Against Climate Change
WESTERN WATER NOTEBOOK: State Designates Aquifers 'Natural Infrastructure' to Boost Funding for Water Supply, Flood Control, Wildlife Habitat

Groundwater recharge in Madera CountyA new but little-known change in California law designating aquifers as “natural infrastructure” promises to unleash a flood of public funding for projects that increase the state’s supply of groundwater.

The change is buried in a sweeping state budget-related law, enacted in July, that also makes it easier for property owners and water managers to divert floodwater for storage underground.

High-Tech Mapping of Central Valley’s Underground Blazes Path to Drought Resilience
Aerial Surveillance Reveals Best Spots to Store Floodwater for Dry Times but Delivering the Surplus Remains Thorny

Helicopter towing an AEM loopA new underground mapping technology that reveals the best spots for storing surplus water in California’s Central Valley is providing a big boost to the state’s most groundwater-dependent communities.

The maps provided by the California Department of Water Resources for the first time pinpoint paleo valleys and similar prime underground storage zones traditionally found with some guesswork by drilling exploratory wells and other more time-consuming manual methods. The new maps are drawn from data on the composition of underlying rock and soil gathered by low-flying helicopters towing giant magnets.

The unique peeks below ground are saving water agencies’ resources and allowing them to accurately devise ways to capture water from extreme storms and soak or inject the surplus underground for use during the next drought.

“Understanding where you’re putting and taking water from really helps, versus trying to make multimillion-dollar decisions based on a thumb and which way the wind is blowing,” said Aaron Fukuda, general manager of the Tulare Irrigation District, an early adopter of the airborne electromagnetic or AEM technology in California.

California Water Agencies Hoped A Deluge Would Recharge Their Aquifers. But When It Came, Some Couldn’t Use It
WESTERN WATER IN-DEPTH: January storms jump-started recharge projects in badly overdrafted San Joaquin Valley, but hurdles with state permits and infrastructure hindered some efforts

An intentionally flooded almond orchard in Tulare CountyIt was exactly the sort of deluge California groundwater agencies have been counting on to replenish their overworked aquifers.

The start of 2023 brought a parade of torrential Pacific storms to bone dry California. Snow piled up across the Sierra Nevada at a near-record pace while runoff from the foothills gushed into the Central Valley, swelling rivers over their banks and filling seasonal creeks for the first time in half a decade.    

Suddenly, water managers and farmers toiling in one of the state’s most groundwater-depleted regions had an opportunity to capture stormwater and bank it underground. Enterprising agencies diverted water from rushing rivers and creeks into manmade recharge basins or intentionally flooded orchards and farmland. Others snagged temporary permits from the state to pull from streams they ordinarily couldn’t touch.

EPA Region 9 Administrator Martha Guzman.Martha Guzman recalls those awful days working on water and other issues as a deputy legislative secretary for then-Gov. Jerry Brown. California was mired in a recession and the state’s finances were deep in the red. Parks were cut, schools were cut, programs were cut to try to balance a troubled state budget in what she remembers as “that terrible time.”

She now finds herself in a strikingly different position: As administrator of the U.S. Environmental Protection Agency’s Region 9, she has a mandate to address water challenges across California, Nevada, Arizona and Hawaii and $1 billion to help pay for it. It is the kind of funding, she said, that is usually spread out over a decade. Guzman called it the “absolutely greatest opportunity.”

Western Water Layperson's Guide to Water Rights Law By Gary Pitzer

California Weighs Changes for New Water Rights Permits in Response to a Warmer and Drier Climate
WESTERN WATER NOTEBOOK: State Water Board report recommends aligning new water rights to an upended hydrology

The American River in Sacramento in 2014 shows the effects of the 2012-2016 drought. Climate change is expected to result in more frequent and intense droughts and floods. As California’s seasons become warmer and drier, state officials are pondering whether the water rights permitting system needs revising to better reflect the reality of climate change’s effect on the timing and volume of the state’s water supply.

A report by the State Water Resources Control Board recommends that new water rights permits be tailored to California’s increasingly volatile hydrology and be adaptable enough to ensure water exists to meet an applicant’s demand. And it warns that the increasingly whiplash nature of California’s changing climate could require existing rights holders to curtail diversions more often and in more watersheds — or open opportunities to grab more water in climate-induced floods.

The San Joaquin Valley has a big hill to climb in reaching groundwater sustainability. Driven by the need to keep using water to irrigate the nation’s breadbasket while complying with California’s Sustainable Groundwater Management Act, people throughout the valley are looking for innovative and cost-effective ways to manage and use groundwater more wisely. Here are three examples.

The Resource

A groundwater pump in the San Joaquin Valley. Groundwater provides about 40 percent of the water in California for urban, rural and agricultural needs in typical years, and as much as 60 percent in dry years when surface water supplies are low. But in many areas of the state, groundwater is being extracted faster than it can be replenished through natural or artificial means.

In the Heart of the San Joaquin Valley, Two Groundwater Sustainability Agencies Try to Find Their Balance

Flooding permanent crops seasonally, such as this vineyard at Terranova Ranch in Fresno County, is one innovative strategy to recharge aquifers.Across a sprawling corner of southern Tulare County snug against the Sierra Nevada, a bounty of navel oranges, grapes, pistachios, hay and other crops sprout from the loam and clay of the San Joaquin Valley. Groundwater helps keep these orchards, vineyards and fields vibrant and supports a multibillion-dollar agricultural economy across the valley. But that bounty has come at a price. Overpumping of groundwater has depleted aquifers, dried up household wells and degraded ecosystems.

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.

Southern California Water Providers Think Local in Seeking to Expand Supplies
WESTERN WATER SIDEBAR: Los Angeles and San Diego among agencies pursuing more diverse water portfolio beyond imports

The Claude “Bud” Lewis Desalination Plant in Carlsbad last December marked 40 billion gallons of drinking water delivered to San Diego County during its first three years of operation. The desalination plant provides the county with more than 50 million gallons of water each day.Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.

In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)

Imported Water Built Southern California; Now Santa Monica Aims To Wean Itself Off That Supply
WESTERN WATER SPOTLIGHT: Santa Monica is tapping groundwater, rainwater and tighter consumption rules to bring local supply and demand into balance

The Santa Monica Urban Runoff Recycling Facility (SMURRF) treats dry weather urban runoff to remove pollutants such as sediment, oil, grease, and pathogens for nonpotable use.Imported water from the Sierra Nevada and the Colorado River built Southern California. Yet as drought, climate change and environmental concerns render those supplies increasingly at risk, the Southland’s cities have ramped up their efforts to rely more on local sources and less on imported water.

Far and away the most ambitious goal has been set by the city of Santa Monica, which in 2014 embarked on a course to be virtually water independent through local sources by 2023. In the 1990s, Santa Monica was completely dependent on imported water. Now, it derives more than 70 percent of its water locally.

California Leans Heavily on its Groundwater, But Will a Court Decision Tip the Scales Against More Pumping?
WESTERN WATER NOTEBOOK: Pumping near the Scott River in Siskiyou County sparks appellate court ruling extending public trust doctrine to groundwater connected to rivers

Scott River, in Siskiyou County. In 1983, a landmark California Supreme Court ruling extended the public trust doctrine to tributary creeks that feed Mono Lake, which is a navigable water body even though the creeks themselves were not. The ruling marked a dramatic shift in water law and forced Los Angeles to cut back its take of water from those creeks in the Eastern Sierra to preserve the lake.

Now, a state appellate court has for the first time extended that same public trust doctrine to groundwater that feeds a navigable river, in this case the Scott River flowing through a picturesque valley of farms and alfalfa in Siskiyou County in the northern reaches of California.

Vexed by Salt And Nitrates In Central Valley Groundwater, Regulators Turn To Unusual Coalition For Solutions
WESTERN WATER SPOTLIGHT: Left unaddressed, salts and nitrates could render farmland unsuitable for crops and family well water undrinkable

An evaporation pond in Kings County, in the central San Joaquin Valley, with salt encrusted on the soil. More than a decade in the making, an ambitious plan to deal with the vexing problem of salt and nitrates in the soils that seep into key groundwater basins of the Central Valley is moving toward implementation. But its authors are not who you might expect.

An unusual collaboration of agricultural interests, cities, water agencies and environmental justice advocates collaborated for years to find common ground to address a set of problems that have rendered family wells undrinkable and some soil virtually unusable for farming.

Could the Arizona Desert Offer California and the West a Guide to Solving Groundwater Problems?
WESTERN WATER SPOTLIGHT: Environmental Defense Fund report highlights strategies from Phoenix and elsewhere for managing demands on groundwater

Skyline of Phoenix, ArizonaAs California embarks on its unprecedented mission to harness groundwater pumping, the Arizona desert may provide one guide that local managers can look to as they seek to arrest years of overdraft.

Groundwater is stressed by a demand that often outpaces natural and artificial recharge. In California, awareness of groundwater’s importance resulted in the landmark Sustainable Groundwater Management Act in 2014 that aims to have the most severely depleted basins in a state of balance in about 20 years.

Groundwater Replenishment

Groundwater replenishment happens through direct recharge and in-lieu recharge. Water used for direct recharge most often comes from flood flows, water conservation, recycled water, desalination and water transfers.

Western Water Excerpt Jenn Bowles

Enhancing California’s Water Supply: The Drive for New Storage
Spring 2017

One of the wettest years in California history that ended a record five-year drought has rejuvenated the call for new storage to be built above and below ground.

In a state that depends on large surface water reservoirs to help store water before moving it hundreds of miles to where it is used, a wet year after a long drought has some people yearning for a place to sock away some of those flood flows for when they are needed.

Aquapedia background

Runoff

Snowmelt and runoff near the California Department of Water Resources snow survey site in the Sierra Nevada east of Sacramento.Runoff is the water that is pulled by gravity across land’s surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream or watershed.

Aquapedia background

Sinkholes

Sinkholes are caused by erosion of rocks beneath soil’s surface. Groundwater dissolves soft rocks such as gypsum, salt and limestone, leaving gaps in the originally solid structure. This is exacerbated when water is acidic from contact with carbon dioxide or acid rain. Even humidity can play a major role in destabilizing water underground. 

Aquapedia background

Irrigation

Irrigation is the artificial supply of water to grow crops or plants. Obtained from either surface or groundwater, it optimizes agricultural production when the amount of rain and where it falls is insufficient. Different irrigation systems are not necessarily mutually exclusive, but in practical use are often combined. Much of the agriculture in California and the West relies on irrigation. 

Aquapedia background

Freshwater

The United States Geographical Survey (USGS) defines freshwater as containing less than 1,000 milligrams per liter dissolved solids. However, 500 milligrams per liter is usually the cutoff for municipal and commercial use. Most of the Earth’s water is saline, 97.5 percent with only 2.5 percent fresh.

Aquapedia background

Springs

Springs are where groundwater becomes surface water, acting as openings where subsurface water can discharge onto the ground or directly into other water bodies. They can also be considered the consequence of an overflowing aquifer. As a result, springs often serve as headwaters to streams.

Aquapedia background

Potable Water

Photo of drinking water filling a glass over the kitchen sink. Potable water, also known as drinking water, comes from surface and ground sources and is treated to levels that that meet state and federal standards for consumption.

Water from natural sources is treated for microorganisms, bacteria, toxic chemicals, viruses and fecal matter. Drinking raw, untreated water can cause gastrointestinal problems such as diarrhea, vomiting or fever.

Extensometers are among the most valuable devices hydrogeologists use to measure subsidence, but most people – even water professionals – have never seen one. They are sensitive and carefully calibrated, so they are kept under lock and key and are often in remote locations on private property.

During our California Groundwater Tour Oct. 5-6, you will see two types of extensometers used by the California Department of Water Resources to monitor changes in elevation caused by groundwater overdraft.

Aquapedia background

Mojave River

Flowing into the heart of the Mojave Desert, the Mojave River exists mostly underground. Surface channels are usually dry absent occasional groundwater surfacing and flooding from extreme weather events like El Niño

Aquapedia background

Alluvium

Alluvium generally refers to the clay, silt, sand and gravel that are deposited by a stream, creek or other water body.  Alluvium is found around deltas and rivers, frequently making soils very fertile. Alternatively, “colluvium” refers to the accumulation at the base of hills, brought there from runoff (as opposed to a water body). The Oxnard Plain in Ventura County is a visible alluvial plain, where floodplains have drifted over time due to gradual deposits of alluvium, a feature also present in Red Rock Canyon State Park in Kern County.

Sustainable Groundwater Management Act (SGMA)

A man watches as a groundwater pump pours water onto a field in Northern California.A new era of groundwater management began in 2014 with the passage of the Sustainable Groundwater Management Act (SGMA), which aims for local and regional agencies to develop and implement sustainable groundwater management plans with the state as the backstop.

SGMA defines “sustainable groundwater management” as the “management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results.”

Seawater Intrusion

Seawater intrusion can harm groundwater quality in a variety of places, both coastal and inland, throughout California.

Along the coast, seawater intrusion into aquifers is connected to overdrafting of groundwater. Additionally, in the interior, groundwater pumping can draw up salty water from ancient seawater isolated in subsurface sediments.

Groundwater Pollutants

barrel half-buried in the ground, posing a threat to groundwater.

The natural quality of groundwater in California depends on the surrounding geology and on the source of water that recharges the aquifer.

Aquapedia background

Overdraft

Overdraft occurs when, over a period of years, more water is pumped from a groundwater basin than is replaced from all sources – such as rainfall, irrigation water, streams fed by mountain runoff and intentional recharge. [See also Hydrologic Cycle.]

While many of its individual aquifers are not overdrafted, California as a whole uses more groundwater than is replaced.

Aquapedia background

Groundwater Treatment

The treatment of groundwater— the primary source of drinking water and irrigation water in many parts of the United States — varies from community to community, and even from well to well within a city depending on what contaminants the water contains.

In California, one-half of the state’s population drinks water drawn from underground sources [the remainder is provided by surface water].

Groundwater Management

Groundwater Legislation

California has considered, but not implemented, a comprehensive groundwater strategy many times over the last century.

One hundred years ago, the California Conservation Commission considered adding  groundwater regulation into the Water Commission Act of 1913.  After hearings were held, it was decided to leave groundwater rights out of the Water Code.

Groundwater Banking

Groundwater banking is a process of diverting floodwaters or other surface water into an aquifer where it can be stored until it is needed later. In a twist of fate, the space made available by emptying some aquifers opened the door for the banking activities used so extensively today.

Aquapedia background

Groundwater Adjudication

When multiple parties withdraw water from the same aquifer, groundwater pumpers can ask the court to adjudicate, or hear arguments for and against, to better define the rights that various entities have to use groundwater resources. This is known as  groundwater adjudication. [See also California water rights and Groundwater Law.]

Groundwater

If California were flat, the volume of its groundwater would be enough to flood the entire state 8 feet deep. The enormous cache of underground water helped the state become the nation’s top agricultural producer. Groundwater also provides a critical hedge against drought to sustain California’s overall water supply.

In years of average precipitation, about 40 percent of the state’s water supply comes from underground. During a drought, the amount can approach 60 percent.

In early June, environmentalists and Delta water agencies sued the California Department of Water Resources (DWR) and the Kern County Water Agency (KCWA) over the validity of the transfer of the Kern Water Bank, a huge underground reservoir that supplies water to farms and cities locally and outside the area. The suit, which culminates a decade-long controversy involving multiple issues of state and local jurisdictional authority, has put the spotlight on groundwater banking – an important but controversial water management practice in many areas of California.

An Expanded Role for Groundwater Storage
September/October 2007

Groundwater, out of sight and out of mind to most people, is taking on an increased role in California’s water future.

Often overlooked and misunderstood, groundwater’s profile is being elevated as various scenarios combine to cloud the water supply outlook. A dry 2006-2007 water year (downtown Los Angeles received a record low amount of rain), crisis conditions in the Sacramento-San Joaquin Delta and the mounting evidence of climate change have invigorated efforts to further utilize aquifers as a reliable source of water supply.

California Groundwater: Managing A Hidden Resource
Jul/Aug 2003

When you drink the water, remember the spring. – Chinese proverb

Water is everywhere. Viewed from outer space, the Earth radiates a blue glow from the oceans that dominate its surface. Atop the sea and land, huge clouds of water vapor swirl around the globe, propelling the weather system that sustains life. Along the way, water, which an ancient sage called “the noblest of elements,” transforms from vapor to liquid and to solid form as it falls from the atmosphere to the surface, trickles below ground and ultimately returns skyward.

Western Water Excerpt Sue McClurgRita Schmidt Sudman

Conjunctive Use: Banking for a Dry Day
July/Aug 2001

Traditionally treated as two separate resources, surface water and groundwater are increasingly linked in California as water leaders search for a way to close the gap between water demand and water supply. Although some water districts have coordinated use of surface water and groundwater for years, conjunctive use has become the catchphrase when it comes to developing additional water supply for the 21st century.
