BAY AREA SUPPLY CONDITIONS:

It's dry, but don't panic — yet; Experts say even with lack of recent rainfall, California isn't in crisis this year

Inside Bay Area – 4/12/07

By Julie Sevrens Lyons, MediaNews staff

 

It's official: For the first time in 15 years, the Bay Area has entered into a drought, according to national climate experts.

 

In a new assessment being released today on the spread and severity of the dry spell affecting the Southwest, drought experts say most of California is experiencing at least "moderate" drought conditions. And a wide swath of Southern California is being plagued by a "severe" drought and could face major crop and pasture losses and widespread water shortages or restrictions.

 

Despite Wednesday's stormyweather, rainfall totals in the Bay Area remain at about half what they should be this time of year, and the Sierra Nevada snowpack — the source of much of California's tap water — is faring even worse.

 

"This is a serious situation," said Brian Fuchs, a climatologist with the National Drought Mitigation Center in Lincoln, Neb. "And we have a feeling that we're underplaying, right now, the situation."

 

But some state water officials said they aren't using the dreaded "D" word — yet.

 

Even as some local cities and water districts begin to call for conservation, we are nowhere near a crisis point, said experts with the state's Department of Water Resources.

 

"We call it a dry year at this point. Not that some people won't be short" on water, said Maury Roos, the agency's chief hydrologist.

 

State officials use a different yardstick from the national experts to determine whether a drought is present, placing much more stock in the levels of the state's biggest reservoirs. Thanks to an unusually wet winter one year ago, the reservoirs are still reasonably full. Which is why the rainfall picture is nothing to panic about, the state says. "One bad year," Roos said, "is not really going to make it a drought."

 

Just the same, many Bay Area water districts have grown increasingly anxious about the dearth of rainfall during this year's not-very-rainy rainy season — if they don't ration water now, they figure, they might regret it later on.

 

Wednesday, more than 2 million Bay Area residents were being asked to cut their water use 10 percent by June — or face mandatory water restrictions. That order affects customers of the San Francisco Public Utilities Commission, which serves 2.4 million customers from North San Jose through San Francisco.

 

And officials at the East Bay Municipal Utility District say they are considering requesting voluntary cutbacks, with a decision expected in the next two weeks.

 

"If it continues to be dry the rest of this year, we have to make plans for how we're going to use the water," said Charles Hardy, a spokesman for the water district. "Because next year could be devastating if it's very dry as well."

 

Indeed, even though state water officials say reservoirs are above their average levels right now, officials expect they won't be by this summer, as demand for water increases. The state is experiencing a double-whammy this year, with not only low levels of rain but abnormally low levels of snow as well. Typically, the melting snow feeds into one of the state's largest reservoirs, the Hetch Hetchy system. But this year, "there just isn't very much snow to melt," said Don Strickland, a spokesman for the state Department of Water Resources.

 

The water content of the Sierra snowpack is now at just 30 percent of normal, a dismally low level that hasn't been seen in nearly two decades.

 

"You've got to go back a long way, all the way to 1988, to see that kind of figure," Strickland said. "Last year, we were at 125 percent statewide. It just goes to show you how much the weather can change from one year to the next."

 

Exactly one year ago, no region of California was experiencing a drought, and only the southeastern section of the state was considered abnormally dry. Now, only a small sliver of land near Eureka and Crescent City is considered not dry or drought-ridden, according to the new national assessment.

 

Los Angeles is experiencing its driest year on record.

 

The Southern Sierra is facing "severe" drought levels.

 

And overall, March "was disappointing" for the state's water suppliers, with precipitation only about a quarter of average and with a loss in the snowpack, according to a state bulletin released last week.

 

Whether you call this a drought, it certainly hasn't been a good year.

 

"There are some ecological impacts already being experienced with streams that are normally flowing this time of year already dried up or low. Some trees are showing some stress in the forest from the lack of rainfall," said the National Drought Mitigation Center's Fuchs. "Much of this is in Southern California — but it's migrating north as conditions continue to worsen." #

Mandatory restrictions: Water agencies say imposed summer cutbacks possible

San Francisco Chronicle – 4/12/07

By Wyatt Buchanan and Christopher Heredia, staff writers

 

More than 2 million Bay Area water users could face mandatory water restrictions this summer if they do not cut back on consumption now, the head of the San Francisco Public Utility Commission said Wednesday.

 

The Sierra snowpack -- the major water source for people in San Francisco, parts of the Peninsula, the South Bay and southern Alameda County -- is less than half of what it should be for this time of year. As of the beginning of the month, the snow pack was at 46 percent of normal.

 

Additionally, precipitation at Hetch Hetchy Reservoir is at the lowest level since 1987 and at the fourth-lowest level since record-keeping started in 1919. The reservoir is the source San Francisco's water.

 

The water and snow levels are being measured every two weeks. Officials will look at the measurements at the end of May and make a recommendation on mandatory restrictions for San Francisco's 2.4 million users, said Susan Leal, general manager of the city's Public Utilities Commission.

 

Mandatory restrictions could mean reducing consumption up to 20 percent. Customers who do not comply could face fines or have their water turned off.

 

Calls for conservation have also been sounded in the North Bay. The Sonoma County Water Agency is asking its 750,000 users in Sonoma, Marin and Mendocino counties to cut back voluntarily.

 

Lake Mendocino, which supplies those users, is predicted to be at its lowest level since the 1970s by September, said Brad Sherwood, spokesman for the water agency.

 

"It's basically going to be a puddle in the lake," Sherwood said.

 

The agency is not looking at mandatory restrictions, but "if conditions maintain and we don't get any major rains the rest of the spring, then anything is a possibility," he said.

 

The East Bay Municipal Water District, which serves 1.3 million customers, hasn't decided whether to call for voluntary conservation. District staff members plan to announce any such measures at a meeting on April 24, said Charles Hardy, spokesman for the district.

 

"Until then, we'll just watch and wait," Hardy said, adding that the last time the district had mandatory rationing was 1989-1991 and before that the mid-to-late 1970s. "We know it's dry and could lead to voluntary conservation. We just don't know yet."

 

In the Contra Costa Water District, officials are encouraging people to conserve but not making a formal request that they do so.

 

"We'll be rolling out a higher level of awareness for people to be careful, because while the situation is tenable this year, if next year is dry, it could be much more serious," said Patty Friesen, spokeswoman for the district, which provides water to 550,000 customers in fast-growing eastern and central Contra Costa County.

 

Other water agencies in Marin and Santa Clara counties do not anticipate any need for voluntary restrictions, representatives said.

 

Rainfall has been below average statewide, and Southern California is especially dry, said Maury Roos, chief hydrologist with the California Department of Water Resources.

 

Previous years have seen above-average rainfalls, however, which can help mitigate that for agencies with large groundwater storage capacity, he said.

 

The San Francisco Public Utilities Commission recommends a number of water-conservation steps, including: turning off the faucet when brushing teeth or washing dishes; taking shorter showers; cleaning sidewalks with a broom and not water; washing machines only with full loads; planting drought-tolerant plants; and replacing old toilets.

 

The last time Bay Area residents experienced mandatory water-use restrictions was during the six-year drought that ended in 1993.

Dry winter produces concern about conserving Bay Area water

Associated Press – 4/11/07

 

The public utility that provides water to about a third of the San Francisco Bay area's population urged customers Wednesday to reduce consumption now to avoid drought limits later in the year.

 

Following California's fourth-driest winter on record, the San Francisco Public Utilities Commission asked customers to cut their water use by 10 percent come June. The commission runs the Hetch Hetchy Reservoir, which pipes water from Yosemite National Park to 2.4 million customers in San Francisco, San Mateo, Santa Clara and Alameda counties.

 

"I'm nervous. We want to do what we can now and get people on track so we can avoid mandatory restrictions. We're way below normal," said General Manager Susan Leal.

 

While Hetch Hetchy is 75 percent full, the Sierra Nevada snowpack that feeds it stood at about 46 percent of normal and the Bay Area has received about half of the rain it would expect in an average year.

 

Regional water managers said that if wet weather does not arrive by the end of the year, the area might well be in for a repeat of its last drought, which ran from 1987 to 1992.

 

Worried about a long-term drought after the unusually dry winter, the city of Santa Cruz already has approved residential water use restrictions set to take effect May 1 that prohibit people from watering lawns during the day.

 

"We don't know what next winter's going to be like," said Bill Kocher, director of the Santa Cruz City Water Department. "If we did nothing this year with the horrible winter we had, I just think it would be careless."

 

Water managers in Sonoma County also urged customers Wednesday to decrease their water use after projections for September showed "dangerously low levels" in Lake Mendocino, a reservoir that serves about 750,000 people and feeds a river Chinook salmon use to spawn.

 

"We are looking at water levels that will be similar, if not worse than those we saw in 1976," said spokesman Brad Sherwood.

 

The Sonoma County Water Agency has not set an overall reduction target, but Sherwood said, "we are asking people to do everything they can at this point."

 

If San Francisco-area customers do not voluntary conserve enough water by June, Leal said she would ask the Public Utilities Commission to approve its first mandatory curbs in 15 years.

 

Back then, the agency issued fines to customers who did not fix leaky faucets and imposed fees on those who used more than their allotted share of water, said spokesman Tony Winnicker.

 

Over the next two months, the utility's staff plans to evaluate which penalties would make most sense if the call for voluntary cuts in water use does not yield results.

 

"We are not in a crisis situation yet, and these requests for voluntary cutbacks are because we believe we don't need to be in a crisis this year," Winnicker said. #

Bay Area residents warned to cut water use by 10%

USA Today – 4/11/07

By John Ritter, staff writer

 

SAN FRANCISCO - One of the driest winters on record prompted water officials on Wednesday to ask Bay Area residents to cut consumption or face mandatory restrictions this summer.

 

The utility that provides water to 2.4 million people here and in three other counties, including Silicon Valley, asked customers to immediately cut water use by 10 percent by June to avoid rationing.

 

"It's premature to call it a crisis, but if we have another year like we had this winter, we'd be in drought conditions," says Tony Winnicker, spokesman for the San Francisco Public Utilities Commission.

 

Meager rain and snow - 27 percent of normal and the fourth-driest winter since 1919 - have left the city's main water supply, the Hetch Hetchy Reservoir in Yosemite National Park, just 75 percent full.

 

Melting snow from the Sierra Nevada usually keeps the reservoir full through the summer. But the Sierra snowpack stands at 46 percent of normal as California's rainy season draws to a close. Water storage is also compromised by earthquake-proofing work on Calaveras Reservoir, which has been drained to a third of its capacity until 2011.

 

Despite the dry winter, some California areas are better off than others. To the south, Santa Cruz will begin mandatory water restrictions May 1, including a ban on lawn watering during the day. Other agencies, including the East Bay Municipal Water District, which supplies Oakland, are considering voluntary cuts.

 

But Los Angeles, which gets half its water from the Colorado River and the Sierra snowpack, has enough water stored underground and in reservoirs to last "at least two years," says Bob Muir, spokesman for the Metropolitan Water District of Southern California. #

GOOD TO THE LAST DROP; Conservation tips: Although most are standard, showering with a friend still not bad idea

San Francisco Chronicle – 4/12/07

By Steve Rubenstein, staff writer

 

It must be serious, because the authorities say it's OK to shower with your spouse again.

 

Same for baths, assuming everything fits.

 

Rain and snow were so sporadic this winter that water could be scarce this summer. Water districts around the state have begun calling for "voluntary conservation,'' as if a two-person shower was an activity hard pressed for volunteers.

 

Unfortunately, many of the water-conservation tricks from past droughts will no longer work.

 

With most toilets, for example, it's no good any more to put a brick into the tank to take up space and save water. That's because modern low-flow toilets already use the minimum amount of water (1.6 gallons per flush) and using less will result in unfulfilling flushes.

 

Modern shower heads are low-flow, too, using 2.5 gallons per minute. Many already feature shut-off valves to allow patriotic folks to take "Navy showers" (soap up with the water off).

 

Older showers can be fitted with new, low-flow shower heads. At venerable Cole Fox Hardware on Fourth Street in San Francisco, low-flow shower heads were selling for $4.99 to $49.99. The higher priced shower heads featured "forceful, soothing droplets,'' otherwise known as water, and "relaxing, full-body showers,'' otherwise known as showers.

 

Of course, said hardware salesman Jon Pogorelskin, a high-flow shower can be turned low-flow with a 5-cent washer, which is good for conservation if not for the hardware trade.

 

Shorter showers and less-frequent showers also save water. So does reusing water, buying an on-off garden hose nozzle, running washing machines and dishwashers only when full and turning off the faucet while shaving and toothbrushing. Also good is building a backyard rainwater cistern which, Pogorelskin said, is a fancy name for an old trash barrel.

 

Voluntary conservation is the official term for the step before mandatory conservation, also known as rationing. On Wednesday, San Francisco water officials warned that if things get dire over the summer, rationing is possible. Water guzzlers could be fined or have their water cut off.

 

Some water users said they had learned from past droughts and were ready to pitch in again.

 

To keep his large lawn in Walnut Creek from dying, Al Sartor said he has learned to use the same water no fewer than three times.

 

"We reused bathwater by using our tub only -- no showers -- then siphoned the used water downstairs into the washing machine for reuse on laundry,'' he said. "Then we pumped the water from the washer out to the lawn.''

 

Other water fans said they were already doing all they could. Herbert Marshall of Pleasanton said he installed a hydroponic vegetable garden after the last drought and isn't sure what else he can do.

 

"I could quit bathing, but my neighbors might complain,'' he said.

 

Kenneth Baird of Fremont said rationing "could mean the end of our backyard vegetable garden," and Jerry Lasky of Danville said water rationing would not do his swimming pool and his half-acre of landscaped grounds much good.

 

At Sloat Garden Center in San Francisco, salesman Alberto Garcilazo said the nursery was featuring a greater selection of succulents, cacti and other drought-resistant plants, in anticipation of customers seeking to thumb their green thumbs at the drought.

 

"Succulents and cactus can be very beautiful,'' Garcilazo said. "And you're going to spend less time in the garden.''

 

The main problem with cactus is what happens when all the water comes back. Also, there are the stickers.

 

"You have to be careful,'' Garcilazo said. "No special secret. Just don't touch them.''

 

Washing cars from the garden hose is a traditional water-waster, but washing cars at most commercial car washes isn't, because most recycle their water.

 

"Water's still good the second time around,'' said Patsy Vargas, cashier at South City Car Wash in South San Francisco, where a wash costs $20 -- air freshener, dashboard cleaning and tire goop extra.

 

"We filter everything,'' she said. "Goes down the drain and gets processed and comes back. Same water, only brand new.''

 

As for the double-occupancy shower, deputy operations chief Pam Jeane of the Sonoma County Water Agency said a drought is no time to be shy. The government fully approves of whatever consenting adults do to reduce consumption.

 

"Absolutely,'' she said. "Shower with a buddy. Everything helps.'' #

Water conservation urged; MENDOCINO COUNTY: Reservoir could drop to record-low level

Santa Rosa Press Democrat – 4/12/07

By Glenda Anderson, staff writer

 

Ukiah Valley’s 31,000 residents could face a water shortage worse than the 1976-1977 drought if a combination of conservation and rainfall fails to adequately fill Lake Mendocino, water officials warn.

ADVERTISEMENT


“It’s real scary,” said Judy Hatch, the Russian River Flood Control and Water Conservation Improvement District president. The agency holds Mendocino County’s right to 8,000 acre-feet of Lake Mendocino water.

The lake currently holds 69,392 acre-feet and has a capacity of 117,232 acre-feet.

But water officials are predicting the lake will drop to 8,000 acre-feet by October unless use drops and more rain appears. The lake has never been that low, said Barbara Spazek, executive director of the Russian River district.

“We’re looking at new territory,” she said.

The dire prediction is based on current water storage in the lake and the rate of water decline between April and October in 2002, according to the Sonoma County Water Agency, which oversees water release.

In the past few years, the diversion that shunts Eel River flows into the Russian River, which feeds Lake Mendocino, has been reduced by about 30 percent in order to save threatened fish on the Eel.

The Sonoma County Water Agency’s primary charge is to ensure there is enough water for Russian River fish, and a portion of that comes out of Lake Mendocino.

“We’re going to go to the regulators and ask them what they want to do,” said water agency engineer Chris Murray.

During the drought of 1977, the lake measured 12,122 acre-feet of water in October. There was so little water on the North Coast that year, people living in Sonoma, Mendocino and Marin counties were asked to share bath water and use it to flush their toilets.

Officials of both the Sonoma and Russian River districts are asking residents and farmers to start conserving water immediately rather than bet on rainfall.

“Conservation needs to happen,” said Pam Jeane, Sonoma County Water Agency’s chief engineer of operations.

She said she doesn’t know if it would be physically possible to take water from the lake if it drops to 8,000 acre-feet. But water removal is not authorized at that low level, she said.

While the future looks dry, Mendocino County officials say there’s still time for the outlook to change.

“We’ll see. It doesn’t take a lot of rain to get the tributaries flowing into Lake Mendocino,” said Janet Pauli, who heads the Inland Water and Power Commission. #

SONOMA COUNTY: Voluntary reductions urged now to avoid crisis situation later

Santa Rosa Press Democrat – 4/12/07

By Bleys W. Rose, staff writer

 

Alarmingly low levels in water reservoirs that supply 600,000 people in Sonoma and northern Marin counties are prompting county Water Agency officials to call for immediate voluntary conservation steps.

ADVERTISEMENT


They want you to:

Limit use of tap water.

Stop watering lawns and plants unless using irrigation controllers that automatically adjust for weather conditions.

Cut out the car wash.

Buy high-efficiency appliances such as low-flow toilets and showerheads, as well as front-loading clothes washers.

California officials said this season is the fourth-driest winter on record. The Santa Rosa area has received only 61 percent of normal rainfall, while the Bay Area has received only half the rain it would expect in an average year.

Water Agency officials said Wednesday that the lack of rainfall has caused low flow levels on the Russian River and prompted concern that fish, particularly endangered salmon, may not survive.

In Santa Rosa, only 17.57 inches of rain has fallen since July 1, far below the 30-year average of 28.88 inches.

The Water Agency’s warning on “dangerously low water supply levels” came the same day that the public utility providing water to a third of the Bay Area announced water consumption reduction measures aimed at avoiding drought limits later this summer.

Hetch Hetchy reservoir stands at 75 percent full, but the Sierra snowpack that feeds it is only 46 percent of normal.

Sonoma County Water Agency officials plan to detail a full package of their own water conservation measures at a news conference today at 10:30 a.m. at Healdsburg Memorial Beach. Water levels on the Russian River are low, indicating fish will have a difficult time using the ladder there to swim upstream to spawn.

“These little forecasts of rain are not going to help us,” Water Agency spokesman Brad Sherwood said. “Water conservation efforts by water contractors, customers and agricultural community are required.”

The San Francisco Public Utilities Commission is asking customers to cut water use by 10 percent. Its advice to Bay Area residents includes installing low-flow shower heads, using drought-tolerant plants and watering gardens at night when evaporation is slower. #

Vallejo has water aplenty; Area drought declaration leaves city in a quandary

Vallejo Times Herald – 4/12/07

By Matthias Gafni, staff writer

 

It's officially a drought. Now make sure to run your sprinklers, your dishwasher and take long showers.

 

Sound odd? Welcome to Vallejo's quandary.

 

As climate officials today officially declare the Bay Area in a drought for the first time in 17 years, Vallejo finds itself flush with water, and walking a tightrope of encouraging wise use - but not too wise.

 

"It's a very touchy topic," said Water Superintendent Erik Nugteren. "I wouldn't suggest anyone waste water, but given our population and the normal water we use, ` we can't be quite as proactive in conserving because it's slightly self-destructive."

 

Bottom line, the water official said: "Water sold is money."

 

Even as the state's snowpack and rainfall numbers are down, Vallejo has "more than sufficient" water for this year and next year, even if there's a drought again next year, Nugteren said. "We're not even close to declaring a requirement for conserving," he said.

 

In fact, the city would be worse off if residents cut back too much on water usage, he said. "If conservation goes at a rate unnecessary, it will basically bankrupt the reserve fund," he said.

 

In 2004, after years of frozen water rates, the city raised them by as much as $3 per month per household.

 

The move was to restore the depleted reserve fund, which had dried up after years of covering the water department's dwindling revenue. The idea of the back-up fund was to provide a buffer in the event of a catastrophic drought, allowing rates to stay level, Nugteren said.

 

A little over two years after the water rate increase, the city has established a paltry $2 million reserve fund, Nugteren said, nowhere near where it should be.

 

Vallejoans use about $15 million to $17 million worth of water each year, he said.

 

If all residents cut water use by 25 percent, Vallejo would lose more than $4 million annually, he said, and the current reserve wouldn't cover those losses. The difference would most likely be taken from water users' pockets, he said.

 

If the snow and rain stay away for a couple more years in a row, he said, conservation then would be considered.

 

Vallejo's worst-case scenario would be three consecutive drought years with the city built out, where the anticipated water shortage would be 10 percent to 15 percent of the city's demand, Nugteren said.

 

The city's water conservation plan, under that scenario, would launch mandatory restrictions and reductions, and also have water rate increases as an option.

 

Even then, Vallejo could use its vast array of small city-owned reservoirs.

 

"Our predecessors did a pretty good job of getting multiple sources for the city," Nugteren said.

 

The situation isn't as rosy for American Canyon and Benicia, which get all their water from the North Bay Aqueduct, leaving them at the whim of state officials.

 

American Canyon Public Works Director Robert Weil expects to hear from the state Department of Water Resources by the end of the month on how much water the city will get from the Delta water supply.

 

According to the city's Urban Water Management Plan, its water supply could drop as much as 72 percent in as little as one dry year. If it used its Vallejo water reserves, that shortage would drop to 20 percent, Weil said.

 

In the past, American Canyon has discussed restricting development due to water issues.

 

Benicia also relies strictly on Delta water distributed by the state. It also has a plan to buy water from Vallejo in an emergency.

 

An added concern is half the city's raw water goes toward Valero's oil refinery to cool its towers. Officials have looked into using wastewater instead, and the city has also said it would ask the refinery to cut production during a severe drought.

 

A late call to Benicia wasn't returned Wednesday.  #

CENTRAL VALLEY SUPPLY:

SSJID may only have 90% of needed water

Manteca Bulletin – 4/12/07

By Dennis Wyatt, Managing editor

 

Water deliveries to South San Joaquin Irrigation District farms and cities could end up being 90 percent of normal this year.

Projections made by the managers of Tri-Dam — a joint dam and power system operated by SSJID in conjunction with Oakdale Irrigation District on the Stanislaus River watershed — anticipate water supplies to be 10 percent less than a normal year.


That has prompted SSJID leaders to start exploring ways to minimize the impact on customers.

“We don’t want anybody to panic,” said SSJID General Manager Steve Stroud. “We believe there are things that we can do to conserve that can ease the impact.”

The official Department of Water Resources projection for the Stanislaus River won’t be issued for about six days.

Even if it shows a rosier outlook than Tri-Dam operators anticipate, Stroud said it will still be a good exercise to explore conversation options.

 

“Anytime you can conserve water it’s a good thing,” Stroud said.

Stroud said if it is done right and the district can only deliver 90 percent of normal water supplies, it could probably be done by adhering to scheduled irrigation runs every 10 days.

“You sacrifice some customer service for efficiencies,” said Stroud. “That means if they are not ready for water when the run starts they can’t make arrangements for a special run a few days later. They’ll have to go 10 days before the next run to get water.”

Stroud said it may require growers to manage their crops and orchards a bit differently to be ready for the irrigation runs every 10 days.

Three cities receive all or part of their domestic water supplies from SSJID — Manteca, Lathrop, and Tracy.

Manteca already has started mandatory water conversation rulers that go into effect every spring through fall. The rules went into place after the drought of 1976-77 put severe strains on surface and ground water supplies.

It is doubtful that Manteca municipal customers will feel any impact of any water cutback that may occur in the coming months.

 

The city operates on a dual surface water and well water system. Ground water would be able to make up any potential shortfall in Manteca’s domestic water supplies.

SSJID receives 3000,00 acre feet of water a year from New Melones Reservoir. Ninety-percent delivery would amount to 275,000 acre feet. Because SSJID’s share is almost entirely based on inflow into New Melones and not the storage capacity, the district’s water share is susceptible to potential problems such as cool, dry winds in the Sierra that would trigger severe evaporation while taking away from run-off. #

GROUNDWATER:

Editorial: The Valley's liquid asset

Pasadena Star News – 4/11/07

 

DROUGHT-stricken Southern California got some good news Tuesday: The aquifer beneath the San Gabriel Valley expanded by two inches due to excessive ground-water recharge.

 

The San Gabriel Basin actually pushed up and out when rainwater and snowmelt from a wet 2005 engorged the underground lake.

 

While water experts predict this won't last, the glass-half-full lesson is this: We are sitting on the San Gabriel Valley's best attribute. The underground basin or aquifer can hold about 2.8 trillion gallons of fresh water, that's more than twice the amount used by all Southlanders every year.

 

While Gov. Arnold Schwarzenegger and the state Legislature focus on getting more water from the Sacramento Delta, or building more above-ground reservoirs, they miss the fact that we already have the most vast "reservoir" in the state, a natural one that exists underground, one that doesn't need a huge investment of expensive steel-and-concrete supports, one in which the water it holds is not subject to evaporation.

 

The importance of the San Gabriel Basin aquifer cannot be over emphasized. It is a vast, strategic resource, not only for the approximately 2million San Gabriel Valley residents, but it could one day be used to supply water to other regions in California.

 

The local aquifer is not used up to its potential for a couple reasons. First, pockets are polluted from industrial solvents, dry cleaning fluids and rocket-fuel carelessly spilled into the drinking water source by hundreds of companies for the past 60 years.

 

For our own water security, and to put the San Gabriel aquifer in play in the state's water supply solution, cleanup of the basin must be fully funded. While the Congress has supplied federal dollars to this goal, the state has contributed few dollars toward this end. It makes sense that the governor's proposed 2008 ballot measure that would allocate $4.5 billion in bonds for new water storage include cleanup, recharge and delivery systems for the San Gabriel Basin aquifer.

 

Second, if the aquifer is to be used more efficiently, there needs to be more spreading grounds and recharge of both local and imported water.

 

Currently, water from the State Water Project is piped into our basin about 30-60 days out of the year, when an excess is available. The state should invest in piping in more water from the Delta to store in the San Gabriel Basin and eventually, to sell to other agencies during times of need.

 

While use of the aquifer to meet other areas' water demands would require a large investment, it should be considered as part of the solution for the state's water needs. #

Editorial: Water foresight

Riverside Press Enterprise – 4/11/07

 

A future of hotter weather and water shortages does not have to mean catastrophe for California. But it will require changing long-held water habits at the state, local and individual levels. And while such changes may be difficult, or even painful, the alternative is much worse.

 

A report released last week by the U.N. Intergovernmental Panel on Climate Change clearly explains the stakes for California.

 

By mid-century, arid regions such as California could see a 10 percent to 30 percent decrease in available water. And the report finds at least a 90 percent certainty that "warming in western (North American) mountains is projected to cause decreased snowpack, more winter flooding, and reduced summer flows, exacerbating competition for over-allocated water resources."

 

Such changes would have profound effects on California, a prospect that demands civic attention. The state depends heavily on the Sierra snowpack to store water for the dry summer months. Winter storms that bring rain instead of snow mean that the water runs off during the wet season, instead of lingering as snowpack until warmer weather.

 

To start addressing these dynamics, California should devise ways to catch and use storm water, a necessity as the snowpack diminishes. Gov. Schwarzenegger's proposal to build two new dams faces strong opposition and an uncertain future, but a renewed legislative focus on water storage would be vital and timely.

 

Local and regional water agencies can also help stockpile water. Efforts to boost water storage in the Chino and Beaumont basins, for example, can accommodate growth while hedging against drought.

 

And conservation can pay enormous water dividends. City and county policies that encourage water-efficient development can stretch supplies through water-saving appliances, drought-resistant landscaping and irrigation with recycled water. And every Californian can take such basic steps as turning off lawn sprinklers during rainy weather and fixing leaky faucets.

 

A drier climate and shrinking water supplies pose big challenges. But Californians are better off pursuing solutions now, rather than waiting until a crisis descends.  #
