CLIMATE ISSUES:

In California, warming trend renews water debate

Associated Press – 4/7/07

ORANGE COVE, Calif. -- A century ago, when Harvey Bailey's great uncle happened upon this spot where California's Central Valley begins its ascent toward the Sierra Nevada, he could tell it was a land made for farming.

Rich soils, abundant ground water, moderate temperatures. His ranch flourished as a modest family citrus farm since he planted the first tree in 1913.

 

Three decades later came a change that would transform not just the Bailey ranch, but the entire San Joaquin Valley. A dam in the foothills to the northwest created Millerton Lake, and nine years after that -- 1952 -- a canal carried water from the reservoir to farming communities lining the edge of the valley from Fresno to Bakersfield.

 

 

California and the federal government had embarked on an era of building dams and hundreds of miles of canals, an ambitious engineering feat designed to capture the massive Sierra snowmelt and channel it to the state's far-flung cities and farms. It marked the beginning of California's population explosion and transformed the Central Valley into one of the richest agricultural regions in the world.

Roughly half a century after that era ended, California finds itself forced to rethink its extensive system of capturing and delivering water. The state's expanding population is part of the reason, but it is the effects of global climate change that have given policy makers a sense of urgency.

Climate change is expected to alter California's hydrology in dramatic ways. Scientists predict the available supply of water may not be able to meet demand, while the existing levee and reservoir systems will be insufficient to contain spring flooding. Finding solutions and ways to pay for them already is proving contentious, opening a new chapter in California's ongoing saga of water wars.

The debate has pitted farmers and metropolitan water planners who argue for more dams and canals against environmentalists and Democrats who control the Legislature. They favor conservation and oppose any measures that will leave a heavy imprint on the environment.

California's era of dam-building helped the Bailey ranch evolve from a humble family farm into a massive citrus operation with 2,000 acres of orange and lemon trees. Harvey Bailey believes a transformation similar to the one California undertook more than half a century ago will be required to ensure its farms and cities thrive in the decades ahead.

"You can't sit on your thumbs and not plan for the future," Bailey said. "Planning for the future means you've got to have more water supplies you can draw on year round."

California requires a lot of water, mostly for its nearly $32 billion-a-year agriculture industry. The state uses 43.1 million acre feet a year, enough water to fill three Lake Tahoes.

Yet scientific models show the state's water supply to be the natural resource most vulnerable to the effects of rising global temperatures. The state's leading scientists and hydrologists generally agree on the potential consequences. Among them:

-- The Sierra snowpack is expected to shrink and melt faster, leaving insufficient supplies for cities, farms and hydroelectric plants during the hottest months of summer and fall, when demand is greatest.

-- Prolonged droughts along the Colorado River will force California and six other Western states to reduce how much they draw from the river.

-- A rising Pacific Ocean will push salty ocean water into the Sacramento-San Joaquin Delta, the heart of the state's water-delivery system. That could jeopardize the fresh water supplies for 23 million Californians -- two-thirds of the state's population.

-- Earlier melting of the snowpack coinciding with spring storms could overwhelm any part of the 1,600 miles of earthen levees, flooding Central Valley communities that have seen an explosion of suburban growth in recent years.

The most crucial piece of California's water system is the snowpack that builds each winter along the 400-mile-long Sierra Nevada. It acts as California's natural reservoir, holding a third of the state's water for drinking and irrigation.

For decades, the natural cycle has remained relatively unchanged: The snowpack builds through winter and early spring, then melts gradually from late spring through midsummer. That allows the reservoirs to fill and state water managers to release the water in late summer and fall, operating on a schedule that satisfies cities and farmers.

Warming temperatures already are beginning to disrupt that pattern.

"We're going to have more water when we don't want it and less water when we want it," said John Dracup, an environmental engineering professor at the University of California, Berkeley and an expert on California's hydrology.

The Sierra snowpack already is showing signs of change, similar to those seen in Colorado and other Rocky Mountain states.

Overall, it has shrunk about 10 percent below its wintertime average. The water content contained in the snowpack this spring, the calculation that determines summer water deliveries, was at its lowest level in nearly two decades.

Scientific models show even warmer temperatures in the future could result in far more precipitation falling as rain than snow, reducing the snowpack 25-50 percent by the end of the century.

The situation is equally alarming along the Colorado River, which provides water to seven Western states but is in the midst of a prolonged drought. Southern California gets about 20 percent of its water from the Colorado.

A report released in February by the National Research Council projects more severe droughts along the Colorado River in the Southwest as temperatures rise. The council is part of the National Academies, an independent organization chartered by Congress to advise the government on scientific matters.

Cities and irrigation districts throughout California have become increasingly vocal about addressing the threat of future water shortages, saying they cannot afford to wait.

The agency that supplies water to much of Silicon Valley, for example, has begun incorporating the possible effects of climate change into its water-management plans, much as it does for earthquakes and flooding.

As part of that effort, the Santa Clara Valley Water District is trying to make itself less reliant on the delta, a system that provides half the district's water but is especially vulnerable to rising sea levels that would make the water too salty. The agency is developing recycling and conservation projects and is working with other San Francisco Bay area water agencies to build a pilot desalination plant.

"Local governments and local water districts are going to have to plan now for the future," said Tony Estremera board chairman of the Santa Clara Valley Water District. "It's time for the reality of global warming. We have to get ready to deal with the problems."

Dealing with those problems on a statewide scale, however, will not prove easy.

The options vary widely but have a common thread: All are expensive.

Farmers, agricultural irrigation districts and some city water managers favor building more reservoirs, an idea that has at least the partial backing of Gov. Arnold Schwarzenegger. He has proposed spending $4.5 billion to build one reservoir in a valley north of Sacramento and another in a canyon above Millerton Lake near Fresno.

That reservoir has enabled Bailey and his brother to more than triple the size of their great uncle's farm in the aptly named Orange Cove. But competition for the water is increasing, as the town has doubled in population since 1990, a trend seen throughout the Central Valley.

This past year, the town's mayor negotiated with a neighboring county for additional water.

Bailey and other farmers say they need an additional reservoir if they are to have enough water to meet their irrigation demands in the years ahead.

"If you don't get rain, you've still got to put water on the crops," Bailey said.

The rapid growth in the Central Valley and the prospect of changing conditions in rivers and reservoirs has begun to worry many California government leaders and water managers. The water content contained in the central Sierra snowpack this year was less than 50 percent of normal in the most recent survey taken in late March, a reading that was apparent at Millerton Lake last month.

Much of the boat ramp remained exposed, and the high water point was visible on the rocks along the shoreline, like the ring around a draining bathtub. Bailey and others said building a second reservoir above the existing one would ensure ample water supplies even in dry years.

State water officials support that view.

"Storage has a whole different feel to it now," said state Department of Water Resources Director Lester Snow. "It's a way to manage the potential impacts of climate change."

Environmentalists and Democrats in the Legislature see it differently. They oppose building new reservoirs and favor alternatives such as storing more water in underground aquifers and implementing tougher conservation measures.

California already has made major strides in reducing its water use. The state's total annual water consumption has remained the same since 1970 even as its population has ballooned to nearly 37 million. Its per capita water use has plunged to less than half of what it was then.

But even with such success, conservationists say more should be done, especially with the state's population expected to hit 55 million by 2050.

Among the proposals they favor is spending $2 billion over seven years to increase the use of water-saving devices such as low-flush toilets and low-flow shower heads. They also urge increased water recycling for use in industrial plants, to recharge underground storage basins and restore wildlife habitat.

Environmentalists advocate changing the way water is released from the state's 1,300 reservoirs so the action is better coordinated with meteorological forecasting. Current practices waste about 20 percent of the state's water, said Aris Georgakakos, a Georgia Tech University civil engineering professor who has studied the American River system near Sacramento.

Opponents of new reservoirs say desalination, while expensive, would provide a more cost-effective alternative.

"Climate change is not a justification for building new storage," said Peter Gleick, president of the Oakland-based Pacific Institute for Studies in Development, Environment and Security. "At the moment, there are cheaper, faster alternatives to meet those same needs."

As difficult as it will be to reach consensus over new dams, no debate is expected to be as contentious as the proposal for a canal to divert fresh water around the delta.

A $3 billion canal would send Sacramento River water around the environmentally fragile delta directly to cities in Southern California and the San Francisco Bay area, boosting water exports by 6 million acre feet a year.

Doing so would remove the potential for catastrophe if sea levels rise or an earthen levee gives way and allows water from San Francisco Bay to rush in. Such scenarios would make the water too salty for urban or farm use.

California tried a similar proposal in 1982 in an initiative that divided the state. Voters in the north resoundingly defeated the proposed Peripheral Canal because they feared too much water would be shipped south -- anxiety that continues to resonate.

The sharp divisions already evident over dam-building, a canal to circumvent the delta and other proposals have prompted some lawmakers and policy experts to call for a temporary break in pitching such projects.

They say more study is needed before California embarks on an expensive quest for solutions that ultimately could prove insufficient or counterproductive.

"California water policy has always been done in fits and starts," said Assemblywoman Lois Wolk, D-Davis, one of the Legislature's top water experts. "All the easy things have been done. All the truly hard decisions are left."

A look at where Californians get their water for farms and cities

Associated Press


How does a state with nearly 37 million people get enough water for irrigating crops, keeping golf courses green and taking showers? A complex system of local, state and federal water projects has done the job for decades. Here's a look at California's water sources:

-- Central Valley Project: Controlled by the federal government, it is the state's largest supplier of water. The project links 20 dams and reservoirs and nearly 500 miles of canals and pumping stations from the Trinity River east of Redding to the base of the Tehachapi Mountains south of Bakersfield. The U.S. Bureau of Reclamation delivers roughly 7 million acre feet of water a year, irrigating a third of the state's farmland and supplying drinking water for 4 million people.

-- State Water Project: The 444-mile California Aqueduct is the heart of the state-run water program. It sends water from the north -- which gets most of the rainfall and snowmelt runoff -- to the San Francisco Bay area and Southern California. The network of 33 reservoirs and aqueducts conveys water south from Lake Oroville, ending at Lake Perris in Riverside County. The state Department of Water Resources delivers about 3 million acre feet of water each year to more than 23 million Californians and 755,000 acres of farmland.

-- Colorado River: California is one of seven Western states drawing water from the Colorado River, using it to irrigate crops in the Palo Verde, Imperial and Coachella valleys. It also is a vital source for Southern California cities, including Los Angeles and San Diego.

-- Groundwater: California pumps an estimated 16.6 million acre-feet a year from its underground water basins. The state's 525 aquifers are estimated to hold nearly 20 times the amount of water that can be stored behind the hundreds of reservoirs in the state. Scientists say between 250 million acre feet and 450 million acre feet of groundwater can be pumped economically, six times more than the amount of water stored in reservoirs.

-- Local supplies: More than 600 cities and local agencies provide water through locally developed projects and imported supplies. One example is San Francisco's Hetch Hetchy Reservoir project, which pipes water from the Yosemite Valley to the city.

Are more dams California's way to cope with global warming?

Associated Press – 4/7/07

 

Gov. Arnold Schwarzenegger has proposed $4.5 billion in bonds to build two new dams, which his administration says are needed to boost water supplies. Most Democratic lawmakers and conservationists are opposed. Here are some of the issues involved in the debate:

Q: Why are more dams under consideration?

 

A: Scientists say climate change will reduce California's snowpack -- its largest source of water -- by as much as 90 percent by the end of the century. Department of Water Resources director Lester Snow has said dams are a key part of the state's strategy to accommodate future population growth and the effects of global warming.

 

 

Building more reservoirs would give the state more space to store about 3 million acre feet of water. By comparison, Lake Oroville north of Sacramento holds about 3.5 million acre fee. The additional water likely would be used for water supply, restoration of fish habitat and improving water quality.

The additional dams also could provide more places to send water when rivers in Northern California and the Central Valley are close to topping their banks and levees, potentially saving communities below the dams from flooding.

Q: What are some of the concerns about building new dams?

A: Dams are expensive and alter the natural flows and habitats of rivers. Opponents say a dwindling snowpack could make some existing dams obsolete because global warming could lead to less water flowing from the Sierra as snowmelt. They say the state should invest money on alternatives such as conservation efforts, desalination, water recycling and recharging groundwater.

Q: Where could dams be built?

A: The state has two leading candidates for new reservoirs. The first is known as Temperance Flat in the narrow canyon above Millerton Lake on the San Joaquin River, northeast of Fresno. It could hold up to 1.3 million acre feet of water, which local officials and farmers say they need to satisfy agriculture and a growing population.

The state is considering another area along the Sacramento River in the rolling hills and grasslands of the Antelope Valley, about 60 miles north of the state capital. River water would be diverted to the valley and would flood about 14,000 acres.

Q: Why don't we just finish the Auburn Dam?

A: It's the project that never seems to go away. Congress approved a dam along the American River in the 1960s as a way to provide more water to farmers in the Sacramento and San Joaquin valleys. But a 5.7-magnitude earthquake in 1975 north of Sacramento exposed a fault line that ran under the construction site, bringing the project to a halt.

Republicans in Congress are anxious to get construction crews back to the dam site in the Sierra foothills east of Sacramento. Supporters say it will improve Sacramento's flood protection, but recent cost estimates have put the price tag at more than $10 billion. It's unlikely the Democrat-controlled Congress will back such an expensive dam in a scenic canyon of the American River.

Q: What are the alternatives to dams?

A: Local water agencies are trying to improve methods to recycle water for use at industrial plants, to recharge groundwater basins and restore habitat. Some coastal cities are considering removing salt from sea water, but the technology is expensive.

Pumping water into the ground could free up reservoir space, but one limitation is the amount of time it takes for water to seep into deep aquifers.

The state Department of Water Resources estimates that cities can save up to 2.3 million acre feet of water by encouraging residents to install low-flush toilets and other water-efficient devices. Meanwhile, farmers can reduce the amount of water used for agriculture by as much as 2 million acre feet by 2030 if they use water-saving pipes and switch to crops that require less water.

Q: Is the Peripheral Canal back?

A: State Sen. Joe Simitian, D-Palo Alto, has introduced a bill that would allow for a canal that sends Sacramento River water around the delta. The idea was resoundingly defeated by voters in the 1980s, but the fragility of the Sacramento-San Joaquin Delta has led some researchers to give the proposal another look.

A canal would deliver fresh water directly to the San Francisco Bay area and Southern California. Relying on the delta is risky for several reasons: Rising sea levels or a break in an earthen levee could contaminate delta water with higher levels of salinity, making it useless for municipal and agricultural use. #

Editorial: As climate changes, water policies must as well; You don't need a weather man to know which way that hot, dry wind's blowing

Sacramento Bee – 4/8/07

 

In the Sierra Nevada, the snowpack that feeds much of California's water supply is less than half of normal for this time of year. What little white stuff has accumulated in the mountains is melting faster and earlier than usual.

 

At Lake Mead, which supplies water to Las Vegas, Los Angeles and other cities, this massive reservoir is 80 feet lower than its historic average. Across the Southwest, farmers and cities are scrambling to drill wells, build pipelines and take other measures to cope with a seeming drought.

 

Scientists can't say with certainty that such dry spells are the result of global warming, but the reports create a worrisome backdrop on which to consider the second report this year of the Intergovernmental Panel on Climate Change.

 

Released Friday, this report concluded, with 90 percent confidence, that human activity is causing global warming and that this greenhouse effect is already causing impacts across the planet.

 

In general, the climatic shift is causing more rain to fall and growing seasons to lengthen in areas closer to the world's poles. It is also contributing to longer dry spells and hotter temperatures in the middle latitudes, the IPCC concluded.

 

The report, the work of 2,500 of the world's top scientists, poses challenges for policymakers at every level of government.

 

If scientific projections play out as expected, impoverished nations of the world will bear the brunt of intensified climate change, even though they are minor contributors to the problem. They will see their heavily populated coastlines inundated as sea levels rise and will face more deadly floods, droughts and changes in agriculture.

 

Here in California, many scientists suspect that global warming is contributing to an earlier-than-normal melt-off of Sierra snowpack, although given natural climate variability such isolated events are hard to nail down.

 

Scientists also see increasing evidence that the U.S. Southwest is moving toward a more arid climate, resulting in more wildfires and water shortages.

 

"There is a broad consensus amongst climate models that this region will dry significantly in the 21st century and that the transition to a more arid climate should already be under way," said a study published online Thursday in the journal Science.

 

In California, the time has long passed for the U.S. Army Corps of Engineers, the Bureau of Reclamation and the state to examine how they operate dams and water projects. The diagrams that determine how much water should be saved for irrigation, or released to create space for floods, are based on historical data that are losing their relevancy.

 

Utilities that depend on hydropower -- such as the Sacramento Municipal Utility District -- must brace for a changed future. So must farmers, fishermen, ski resorts and anyone whose livelihood relies on climate patterns of the past.

 

In the Legislature, there are encouraging signs of adjustment. Republican lawmakers who voted last year against California's law to reduce greenhouse gases now are touting new reservoirs as a response to climate change. We welcome the debate.

 

Everything must be on the table, as long as all parties recognize the obvious: Global warming is real. #

Editorial: A little goes a long way

Pasadena Star News – 4/9/07

 

THE debate over global warming rages on. It's either "the greatest hoax ever perpetuated on the American people" (Sen. James M. Inhofe, R-Okla.) or "Our house is burning down and we are blind to it" (French President Jacques Chirac).

 

But at the same time that the global warming argument rages at lofty scientific and political levels, we are experiencing our own climate problems down here at street level.

 

Southern California finds itself in the midst of a drought, one that extends to the east and west slopes of the Sierra and into the Colorado River basin. And whether the cause is global warming or cyclical weather patterns, it's time for action, not words.

Consider:

 

The water content in the Sierra snowpack is at its lowest level in two decades, meaning that water supplies to cities and farms could be affected if conditions persist.

 

The Colorado River system is in the midst of one of the worst droughts in centuries.

 

As a result, Gov. Arnold Schwarzenegger is pushing for a ballot measure in 2008 that would allocate $4.5 billion in bonds for new water storage in the state.

 

It has been the driest winter in the Los Angeles area since records began in 1877.

 

If that's not enough, JPL researchers have determined that temperatures in California are on the rise, much of that attributable to urban sprawl.

 

If these conditions continue for one or two more decades, the situation could become dire. While prolonged droughts haven't occurred in hundreds of years, there is no guarantee it won't happen again. Mother Nature is adept at throwing curve balls.

 

It isn't too soon to begin practicing conservation on a personal level. It won't hurt. And it will help.

 

Here are some tips from conservation specialists:

 

Install aerators in your faucets, use high pressure showers and ultra low-flush toilets throughout your home.

 

Water your lawns early in the morning before sunrise or in the evenings after sunset. This will maximize water absorption into the soil and minimize loss due to evaporation.

 

Take short showers. Draw less water for baths. Turn off the water while brushing your teeth or shaving. Check for and fix "silent" leaks in toilets or plumbing fixtures.

 

Support local businesses that practice conservation. For example, commercial car washes that recycle their water; businesses that use recycled water in fountains; restaurants that serve water only on request; and hotels that give you the option of using your linens for a second night's stay.

 

Live like we reside on the edge of a desert - because, after all, we do. #

DELTA ISSUES:

Guest Column: As Sacramento fiddles, the wells run dry

Pasadena Star News – 4/6/07

By Tony Fellow, chair of the Department of Communications at California State University, Fullerton, vice chair of the Metropolitan Water District of Southern California, and director on the Upper San Gabriel Valley Municipal Water District in El Monte

 

When the wells run dry, we know the cost of water," the little ditty goes. Southern Californians may soon know just how expensive its liquid gold is, thanks to Sacramento.

 

A colossal bureaucratic snafu in the state's capital may shut down a major artery supplying water to 25 million Californians within 60 days. Its impact could all but cripple California's economy if agencies up north don't get their act together.

 

Alameda County Superior Court Judge Frank Roesch last week ordered the state to shut down the Harvey O. Banks Pumping Plant, west of Stockton, by June if the state Department of Water Resources doesn't provide the court with the proper permits that would allow it to kill two of California's endangered species - salmon and Delta smelt.

 

Watershed Enforcers, a group of sport fishermen who have had it with the plant's enormous pumps sucking in and killing salmon and other fish, initiated the action against the DWR. The state agency was caught off guard - or just arrogant - not realizing it needed permits from the state's Fish and Game Commission that would allow it to kill spring and winter runs of the endangered species. DWR's response? "We believe we are in compliance with the law," DWR Deputy Nancy Saracino told State Senate Natural Resources and Water Committee Chairman Darrell Steinberg. That attitude should go over well with the judge!

 

The sport fishermen say that the DWR has not satisfied the mandatory requirement found in the California Endangered Species Act allowing it to take species of winter-run Chinook salmon, spring- run Chinook salmon and Delta smelt.

 

A lot is at stake if the judge permanently pulls the plug on the plant, which shoots some 10,688 cubic feet per second of delta water through 11 pumps into the 444-mile State Water Project aqueduct that supplies water for millions of Californians and 750,000 acres of farmlands.

 

The prospect of shutting down a major artery of Southern California water shook the Metropolitan Water District of Southern California, which gathered its executive committee together for an emergency meeting to meet the challenge of less water.

 

Debra Man, MWD's chief operation officer, underscored the gravity of the situation, which includes potential water shortages, putting California's agricultural industry and the state's economic vitality at stake. She said the MWD, which provides supplemental water to 18million Southern Californians, is prepared to call for voluntary conservation to reduce demand from 10 to 20 percent, as well as discontinue its water deliveries to agriculture. MWD also is prepared to take 250,000 acre-feet from its newest reservoir, Diamond Valley Lake, which stores some 755,000 acre-feet for emergencies, such as earthquakes and Delta levee failure. Arrogance of state agencies, by the way, is not considered an emergency.

 

The mammoth water agency is also prepared to store as much water as it can get in local groundwater basins. But wait a minute, that brings up another problem. In the San Gabriel Valley - home of the state's most water-rich groundwater basin - 200 of its 400 wells have been shut down because they are tainted with volatile organic chemicals and perchlorate, a by-product of rocket fuel that can have adverse health effects. And if that isn't enough, Southern California's other water artery, the Colorado River, is threatened by hot spots of perchlorate and new findings at Topok, Ariz., of chromium VI, another chemical that could have devastating impacts on one's health. These chemicals are slowly creeping toward rivers. And let's not forget the uranium pilings sitting adjacent to the Colorado River at Moab, Utah. This major artery may be on life support if its arteries are not cleansed of what is shaping up to be a toxic cocktail.

 

Judge Roesch's decision also may be a blessing in disguise as the governor begins a whirlwind tour of California's water supplies, touting his water bond measure that will likely find its way on the February ballot. The measure, which calls for building new reservoirs in Northern California, is of little benefit to those in the south. What Southern California needs in that bond is millions of dollars to bring about a speedy cleanup of Southern California's wells and funds to build more recycled water projects.

 

The judge's actions also should be a wake-up call to California legislators who need to get their act together and come up with one comprehensive bill to solve California's water problems and begin serious discussions about California's future and her ability to sustain a growing population with dwindling natural resources. State Sen. Shelia Kuehl, by far the brightest of Sacramento's lot, has warned her colleagues that building more and more homes without assuring the reliability of water is a recipe for disaster.

 

In "The Tragedy of King Richard the Third," William Shakespeare writes, "The people are like water and the ruler a boat. Water can support a boat or overturn it." We may see the power of water if its rulers don't begin to steer California in the right direction as far as water policy is concerned. #

DELTA SUPPLY ISSUES:

Farmers in Delta running short on water

Stockton Record – 4/7/07

By Reed Fujii, staff writer

 

UNION ISLAND - Spring arrived just a couple of weeks ago, but farmers on Union and Roberts islands in the south San Joaquin Delta say their water supplies already are running out.

 

With low water flows and the giant federal and state water systems sucking water out of other areas of the Delta to ship to cities and farms farther south, some irrigation pumps along the south end of Middle River can only run three to four hours a day. And area growers fear the problem will only get worse this summer when natural flows diminish further and irrigation demands grow.

 

Government officials said temporary in-stream barriers should help address the problem, but won't be completed until later this month.

 

In the meantime, however, farmers will have to cope.

 

"Guys are having problems," said Dino Del Carlo. "Like myself, when it's low tide, we don't have any water to pump anymore.

 

"We're going to start planting tomatoes next week and you're really going to have a big problem if you run out of water to irrigate those things," said Del Carlo, who also cultivates alfalfa, asparagus and grain crops in the area.

 

Standing on the Undine Road Bridge over Middle River this week, farmer Bill Salmon pointed to the muddy river bed exposed to the sun at low tide.

 

"We used to be concerned about the quality. Right now the quality has become secondary. All we want is something wet," said Salmon, who grows winegrapes, walnuts and field crops in the area.

 

His own irrigation operations must be put on hold four to five hours a day and it's even worse for others. Salmon said his son, who raises grapes along another stretch of the river, can irrigate for only three to four hours per day.

 

John Herrick, a Stockton attorney who represents the South Delta Water Agency, acknowledged that a relatively dry winter and low river flows may be contributing to the problem.

 

However, he blamed pumps feeding the State Water Project and federal Central Valley Project for pulling down water levels throughout the south Delta. Middle River's bed lies below sea level and would have water in it, save for the massive water exports.

 

"Every year we have things like this," Herrick said. "This is common and it adversely affects every diverter who pulls water out."

 

The California Department of Water Resources is now constructing three in-stream barriers that help maintain south Delta water levels sufficient for irrigation, a state official said.

 

One is due for completion early next week and the other two should be done by April 22, said Mark Holderman, chief of DWR's temporary barriers program.

 

"The combination of those barriers helps boost water levels in the south Delta and that should help the farmers," he said.

 

"The problem is we have permits that don't allow us to get started on them until the first of April, so we can't get them in any sooner," Holderman said. "Normally that isn't a problem, but this has been a pretty dry year and so the farmers are wanting to irrigate now."

 

That should be good news for Joe Ratto, a farmer whose pump near the Undine Road Bridge filled an irrigation ditch with sand, instead of water, as the Middle River ran dry. He was anxious about plans to begin planting processing tomatoes later this month. Having contracted to supply tomatoes to a cannery and already ordered seedling tomatoes to transplant, Ratto is committed to planting.

 

"If they put the barriers in, we should have water," he said. "I don't know about quality, but we'll have water."

 

Herrick also pointed a finger at the U.S. Bureau of Reclamation, which operates the CVP water exports, saying the agency recently increased its pumping rate despite low-water conditions in the Delta.

 

"The bureau doesn't care," he said.

 

The agency is concerned about potential negative impacts from its operations, spokesman Jeff McCracken countered.

 

"We certainly don't like to see other people impacted by our operations. That's what the barriers are for," he said. "Hopefully these folks can get through the next week or so until the state can get those barriers in place and so everybody can get on doing what they been doing for the last 60 years."

 

He acknowledged the bureau had recently increased its Delta water exports to about 3,500 cubic feet per second (about 26,189 gallons per second).

 

That amount, however, still fails to meet demands of CVP water users and the bureau is currently drawing water from San Luis Reservoir to make up the difference, he said. The federal pumps also remain below full capacity of 4,600 cubic feet per second (35,880 gallons per second).

 

That's the rate the agency normally runs in the spring. When California gets a good wet winter, McCracken said, "We're going full blast trying to fill up San Luis Reservoir." #

WESTERN WATER:

Five options on tap in case water dries up ; Southern Nevada favors the plan that involves a mix of banking and credits

Las Vegas Sun – 4/5/07

By Emily Green, staff writer

 

The same day that environmentalists attacked a bill in the Nevada Legislature to limit public access to water appropriation decisions, the people who control the floodgates of the Southwestern dam system milled around the Sierra Room of the Henderson Convention Center, waiting for a concerned public to arrive. Six people finally did.

 

So for most of Tuesday evening, Bureau of Reclamation water masters were their own audience, discussing the most pressing question before Las Vegans: How will a region that feels cheated by its present quota of Colorado River water cope if persistent drought makes the current allotment of 300,000 acre-feet a year seem like the days of plenty?

 

There's water for now, but cutbacks could occur within five years, if bathtub rings forming around Lake Mead continue to drop another 125 feet.

 

The bureau did not bring answers about dealing with shortages but offered a thick bundle of suggestions. Five scenarios dominate the Interior Department's newly issued environmental impact statement. The six people who showed up Tuesday night got a CliffsNotes version, because the original document - with its hundreds of pages, graphs, matrixes and mind-numbing acronyms - is as thick as a Bible and as readily comprehensible as the original Greek.

 

The option favored by the Southern Nevada Water Authority and Colorado River Commission involves a sophisticated mix of water banking and credits - building reservoirs to capture water before it flows to Mexico, along with more flexible river maintenance. Hammered out with stakeholders in the seven states served by the Colorado, the Western imprimatur is signaled with the graceless title "Basin States Alternative."

 

It assumes aggressive conservation, says George Caan, executive director of Nevada's Colorado River Commission. However, while there is much crossover in conservation measures among the various options, the Sierra Club and other environmental contributors prefer the "Conservation Before Shortage Alternative." It includes an intriguing water credit system, not unlike the carbon credits of the Kyoto Protocol. The third contender, the "Reservoir Storage Alternative," keeps reservoirs high and may be most favored by recreational boaters, bureau spokesperson Robert Walsh says.

 

Two of the five options seem to have been expressly included for their value in cutting. The first: "The No Action" alternative stipulates no change in policy, which sounds resigned until you hear about the "Water Supply Alternative." It calls for such concerted inaction that it would keep water flowing even if Hoover Dam ran dry and Lake Mead dried up.

 

The alternative with the consensus and political muscle is the aforementioned Basin States Alternative. Provided the draft study on tour with Bureau of Reclamation officials returns unscathed, some version of it looks likely to be the option that will go to the Interior Department early next year.

 

Certainly there was no resistance expressed Tuesday night.  #

GROUNDWATER:

County Eyes supply, pollution

 

Sonora Union Democrat – 4/6/07

By Katy Brandenburg, staff writer

 

When Brian Moss, director of Calaveras County's Environmental Management Agency, makes public presentations about groundwater, as he has recently, he starts by referencing the gold the county was known for in the 1800s.

 

"What is the gold in California today?" he asks.

 

Many know the answer and shout out, "Water!"

 

Geographic Information System technology has enabled the county since 2000 to track and identify groundwater sources, and possible threats to it, as part of the Local Agency Groundwater Protection Program. Using data already gathered since 1994 — plus latitude, longitude and topographical mapping — GIS and computer design software create a visual representation of the county's geology, including the location of public and private wells, septic tanks, mine sites, dump sites, underground storage tanks (usually gas stations) and underground water sources.

 

"We're building a database, that's the key," Moss said. "That's what makes GIS the wonderful tool that it is."

 

The majority of the groundwater protection program is funded by a grant from the U.S. Environmental Protection Agency. The county has mapped 1,900 wells within three to five feet of the exact location. Records from the state Department of Water Resources listed 4,500 more well locations, but without the same degree of accuracy.

 

Calaveras County gets much of its drinking water from small public water systems and individual wells, and on-site septic systems are common in areas where wells are found. Tracking data from and continuing to monitor those areas is very important, Moss said.

 

For example, prior to 1999, the Mountain Ranch School noticed elevated levels of coliform bacteria, associated with animal or human waste, in its well. The well was very old, so the school drilled a new one and sealed it in concrete to prevent surface water from contaminating it. The bacteria problem continued, and environmental health employees began looking for a pattern in bacteria levels over a period of time. They discovered the levels were highest in the winter and rainier months, and they decreased in the summer, when the ground was drier.

 

GIS maps of the area revealed a geologic formation of limestone and dolomite rock, which allowed water from flooded streams to trickle straight through cracks into the groundwater without being naturally filtered first, as usually happens with denser types of rock and soil.

 

Another small public well in Mountain Ranch had the same seasonal problem, Moss said. Both well owners worked with the Department of Environmental Health to run the water through an extra filtration system to make sure people were not being exposed to the bacteria. The department recommends but does not require owners of private wells to conduct water quality tests at least once a year.

 

The limestone area in Mountain Ranch only covers a limited area west of the town, Moss said. Well owners in that area would want to do their yearly test in the winter or rainy season.

 

Other areas of the county are affected by minerals or metals, such as Salt Springs Valley, Copperopolis and the area around Penn Mine near Valley Springs. High mineral and salt levels in the soil, as well as metals, including copper, pose risks to groundwater. Areas around flooded copper mine shafts tend to have very acidic water, Moss said.

 

Using the GIS data, the department can calculate the potential depth and yield of a new well and choose a good location by looking at maps of the surrounding area. The goal is to continue building a database that will eventually encompass all potential and known groundwater sources in the entire county — and can be used for planning future developments and extending water service to areas that need it.

 

"The more data we have, the more accurate we can be as far as water availability and quality," Moss said. "Sometimes the state even asks us for information."  #

SIERRA SNOWPACK:

Lean snowpack could impact rafting; Lower water content may shorten season for some river activities

Auburn Journal – 4/9/07

By Jenna Nielsen, staff writer

 

The water content in the Sierra snowpack is at its lowest level in nearly two decades, leading to the concern of a possible shortened season for whitewater rafters and other water-sports enthusiasts.

The latest measurements were taken last week near South Lake Tahoe during the fourth snow survey of the season by the state Department of Water Resources. The survey is considered the most important because state hydrologists use it to predict water supplies and deliveries for the summer months.

The water content in the snowpack along the 400-mile-long range averaged 46 percent of normal - the lowest level since 1990, when it was 40 percent of normal.

"If you start putting dry winters together, you deplete the reservoirs," department spokesman Don Strickland said. "We're hoping we don't run into that."

The Sacramento Municipal Utility District controls the flow of water from dams into the Middle Fork and South Fork of the American River.

 

The SMUD board of directors approved a relicensing settlement agreement for the Upper American River Project and Chili Bar Hydroelectric Project (South Fork) in January.

The agreement will allow for water releases six days a week into the South Fork and seven days a week into the Middle Fork.

In June, water will flow to the South Fork every day except Wednesday and in July and August, every day except Monday.

 

Nate Rangel, owner of the Coloma-based Adventure Connection and president of the California Outdoor Rafting Association, said the low-levels will affect the flow of water into the North Fork, shortening the rafting season. "It won't have much effect on the South or Middle forks," Rangel said. "But since there are no dams upstream of the North Fork, there will be a much shorter season - maybe through mid April and May - but I don't expect much past May."

Water flows this spring are expected to be below last year's levels, Rangel said. The flows should be closer to normal, at roughly 1,500 cubic feet per second.

State hydrologists had hoped for a wetter March to boost the snowpack. March storms typically add about 10 percent to 15 percent more snow in the Sierra.

Bill Center, owner of Camp Lotus, which fronts the South Fork of the American River three miles downstream from Coloma, said he has monitored the snowmelt at 6,600 feet for the last 15 years.

"The melt is as hard to predict as the weather," Center said. "But from my experience, the water was about three times higher last year than it is this year."

Center said he expects the North Fork will only get more than 1,000 cubic feet per second for roughly 10 days in April.

"There won't be much in May at all, either," he said. "Of course, all bets are off if it rains or snows, but if people want to get out there and boat, they want to do it by the beginning of May."

Not everyone thinks the low water content will affect rafters and water enthusiasts this summer.

 

"The Middle and South forks are sometimes choppy and unpredictable when it comes to water release, but I think we can pretty much rely on water every day," said John Hauschild, owner of Canyon Raft Rentals in Auburn. "An ideal water flow level for rafting (on the North Fork) is about 900 cubic feet per second and 450 cubic feet per second for kayakers - and I don't think that is going to be a problem this year." Sierra snowmelt also provides more than a third of the state's drinking and irrigation water and is the lifeblood of the State Water Project, which provides water to more than 23 million people and 775,000 acres of farmland.

In addition, about a quarter of the state's power comes from hydroelectric plants that rely on heavy mountain runoff during the spring and summer months.

Each year, state researchers conduct five monthly snow surveys from January to May, measuring the snow at 382 stations. The snow depth last week at Phillips Station south of Lake Tahoe was 35.4 inches, compared with 73.1 inches during the fourth snow survey in 2006.

Electronic sensors showed that the snow's water content was higher in the northern Sierra, where it was 52 percent of normal. The water content was 48 percent of normal in the central Sierra and 38 percent in the southern section of the range.

Wild swings in annual precipitation are common to California. The state went through a drought during the late 1980s and early 1990s, with water content in the Sierra snowpack dipping as low as 30 percent of normal.

And Hauschild is staying positive about the whitewater season just ahead. "The low water content might actually be a good thing," he said. "Last year it was so high that people were scared to come out, but it's always fun for me - I love the big water." #
