NAPA VALLEY WATER SUPPLIES:

Local water cup is 3/4 empty

Napa Valley Register – 12/4/07

Wanted: rain and snow.

That's the buzz in American Canyon.

 

Unless the Sierra Nevada mountains see heavy rain and snowfall this winter, American Canyon -- along with Napa, Yountville and Calistoga -- could receive only a quarter of the water they hoped to import from the Delta next year.

The California Department of Water Resources' initial announcement on water allocations this year was the lowest since 2003.

Unlike the other cities, American Canyon relies primarily on water imported via the North Bay Aqueduct, a pipe that carries water through Jamieson Canyon. The Department of Water Resources manages the supply of the water, which originates in the Sierra and travels via a network of canals and pumps through the Delta, home to the endangered Delta smelt.

The cities could still receive more water if the state's water reservoirs fill up with rainwater and snowmelt.

"It's all up to Mother Nature," DWR spokesman Don Strickland said Monday.

If the dry weather continues, Napa County could receive a total of 5,800 acre-feet of water from the State Water Project instead of 23,200 acre-feet, according to DWR. Each city receives a proportion of that water.

Felix Riesenberg, water resources engineer for the Napa Flood and Water Conservation District, the agency that represents the cities before DWR, and Phil Brun, Napa's general manager of the city's water department, said in separate interviews that the low initial water allocation was expected.

The fear, Riesenberg said Monday, is that dry weather conditions continue.

In the meantime, water contractors throughout the state are looking for new water sources.

American Canyon, Napa, Yountville and Calistoga could buy extra water through the State Water Contractors Association, a group of 27 public agencies that includes the Napa Flood and Water Conservation District.

American Canyon, which could be forced to rely on more water from Vallejo, is also considering expanding its recycled water use and tapping other water districts in California for parts of their supplies.

Unlike Napa, American Canyon has no reservoir, though it can receive treated water from the city of Vallejo.

The county's annual water entitlements from the State Water Project change ever year.

Napa County's water entitlements were 4,400 acre-feet in 1983. By 1998, Napa County was entitled to a total of 11,710 acre-feet. By 2021, the cities of Napa, American Canyon, Calistoga and Yountville's total water entitlements could add up to 29,025 acre-feet. #

CONSERVATION ISSUES:

City, water district may pool conservation efforts

Desert Sun – 12/4/07

By Marcel Honore, staff writer

 

La Quinta could approve today the Coachella Valley's most comprehensive water-saving collaboration with a local water agency.

 

The city's "Cooperative Landscape Water Management" project, a joint effort with the Coachella Valley Water District, aims to reduce runoff and over-watering through several new approaches across La Quinta.

 

The partnership would be the first of its kind in the valley, desert water officials say.

 

"It drives most of us in the Coachella Valley crazy in August and September ... to see those rivers of water in our streets," La Quinta Councilman Tom Kirk said. He said he worked with water district officials to help bring the initiative before the council.

 

The new plan would build on a 2005 pilot program to install efficient weather-based irrigation controllers and curb excess watering across the district's territory. The program saves millions of gallons a year, officials say.

 

"We're trying to build on the success," said Dave Koller, the district's conservation coordinator.

 

Koller said the La Quinta program would add four tactics to help conserve water within the city's limits. It would:

 

Study and implement improvements to save water on public property, such as redesigning median landscaping.

 

Provide incentives for residents to change their landscaping to better save water, like moving sprinklers away from the street.

 

Offer low-interest loans to homeowners associations, to change the community landscaping to help save water.

 

Offer free audits to golf courses and suggest ways they can conserve turf irrigation.

 

The program's price tag is estimated at more than $100,000, Koller said. The City Council will consider setting aside $50,000 during its regular meeting today.

 

The water district's board is set to review the plan Dec. 11, Koller said.

 

The proposal comes as state water officials warn of a looming water supply crisis in California. Environmental concerns have lessened the amount of water Southern California receives from the north, Koller said.

 

The valley is tapping more local groundwater than it should, Koller said, and these efforts in La Quinta would help stop the flow.

 

"It's clear that (water supply) security shouldn't be taken for granted," Kirk said. #

WATER SHORTAGE:

RV water board may declare emergency

Ukiah Daily Journal – 12/4/07

By Ben Brown, staff writer

 

The Redwood Valley Water District Board will hold an emergency meeting on Dec. 11 to discuss the declaration of a water emergency.

 

The board has been considering emergency measures since last week when the Sonoma County Water Agency notified them that the level of storage in Lake Mendocino had triggered a clause in the agreement that allows the water district to draw water from the lake.

 

According to the agreement, if the level of Lake Mendocino drops below 30,000 acre-feet after Oct. 31, the Redwood Valley Water District must cut their withdrawals from the lake by 50-percent of the average for that month for the last three years.

 

As of Sunday, storage in Lake Mendocino was at 29,435 acre-feet.

 

If the board votes to declare an emergency, it will be able to activate an ordinance passed earlier this year which would allow the board to take mandatory conservation measures, up to strict limits on how much water would be available to a household per month.

 

Redwood Valley Water District General Manager Bill Koehler said, currently, the board will be enforcing a mandatory shut-off of agricultural water but will only ask residential customers to increase voluntary conservation to 40 percent through the month of December.

 

A letter to that effect has been sent by the board to all water district customers.

 

The meeting is scheduled for 7 p.m. Dec. 11 at the Redwood Valley-Calpella Fire Station at the intersection of East Road and School Way. #

CLIMATE ISSUES

Editorial: Ask not for whom the global warming bell tolls; Bali is far away, but a new report makes it clear why climate change is a local issue

Sacramento Bee – 12/4/07

 

The Intergovernmental Panel on Climate Change, winner of the Nobel Peace Prize this year, recently released its latest report summarizing the consensus of IPCC scientists on the Earth's warming atmosphere. Its findings are daunting for every nation of the world, for California and for the Sacramento region.

 

Think the weather has seemed relatively warm in recent years? According to the panel, 11 of the last 12 years (1995-2006) rank among the 12 warmest years in recorded history, dating back to 1850, for global surface temperatures.

 

The IPCC is unequivocal in concluding that greenhouse emissions, largely from the burning of fossil fuels, are contributing to warming temperatures and rising oceans. Sea levels have risen about a half-foot in the last century, and are now rising even faster because warmer temperatures are melting ice sheets and expanding molecules in sea water.

 

How high will these oceans rise? Some computer models show that, without a significant reduction in greenhouse gases, the Greenland ice sheet could melt sometime after 2100. Such a steady melt-off would lead to a 7-meter (23-foot) increase in sea levels, according to the IPCC report. That would submerge most of San Diego, San Francisco and Los Angeles. Tidal action would swamp most of Sacramento.

 

Yet even with less dire projections, the future does not bode well for our local area. Earlier this year, some people scoffed when the Independent Science Board of the Bay-Delta Authority said the state should prepare for 28 to 39 inches of sea level rise by 2100. The latest IPCC report suggests that those forecasts are on target, with perilous consequences for the Delta and the state's water systems.

 

By strengthening its levees over time, Sacramento can probably cope with rising sea levels and the tidal effects they will cause in the Pocket and other parts of the region. But for Sacramento, the more immediate concern is how the storm pattern is likely to change.

 

Although scientists acknowledge that it's difficult to forecast regional (as opposed to the worldwide) impacts of climate change, they expect California to experience more intense storms and droughts in the future.

 

The average yearly snowpack is likely to decrease. That means that big rains will fall on barren (and possibly fire-charred) Sierra slopes. The velocity of runoff coming off the mountains will increase because there will be less snow to buffer it.

 

For the next two weeks, delegates from the United States and 190 countries will be meeting in Bali, Indonesia, for a major United Nations conference on climate change. Alone among the world's industrial powers, the United States is resisting a post-Kyoto framework that would set mandatory caps on greenhouse gases, as California has placed on its own industries.

 

These talks may seem far removed from the lives of everyday people, but their outcome matters. The consequences could be as fundamental to our lives as the weather, our water supply and our public safety.

 

That's one reason California is sending its own delegation to the U.N. meeting. Cal-EPA Secretary Linda Adams is tentatively slated to speak to a plenary session next week. She and others hope the Bali talks will be a turning point in the fight against global warming. Will they? Stay tuned. #

NEED FOR FURTHER CONSERVATION:

Editorial: We still need to conserve

Inland Valley Daily Bulletin – 12/4/07

 

OUR VIEW: Rain doesn't end need for faucet thrift.

 

Finally, our high pressure gave way to a rainy weather system from the north, splashing Southern California with a steady dousing of rain on Friday.

 

What does this do for the drought? Does it mean one more storm in the Southland and we can all go back to overwatering our lawns and brushing our teeth with the faucet running? No.

 

Conservation is what put Southern California in a much better position for handling the current drought than we were during the last six-year-drought of 1987-1992, according to Metropolitan Water District Chairman Timothy Brick.

 

It's true.

 

Now - or ever - is not the time to abandon conservation efforts. That means homeowners planting more xeriscapes and using drip irrigation systems or systems they can "pause" before, during and after a storm. That means homeowners buying more low-flush toilets and water-stingy washing machines and dishwashers, and then running those machines only when full. Conservation should be a way of life.

 

After all, the Colorado River Basin is still in a years-long drought, and a judge's order could shut off water deliveries from Northern California through the Sacramento-San Joaquin Delta as early as this month. MWD, which imports water from both those sources, anticipates its water supplies in 2008 will be 30 percent lower than normal. If so, it might mandate lower usage by water agencies across the region, which could lead to water rationing as soon as March, some water officials say.

 

Still, we're much better prepared than we used to be.

 

After 1992's "March Miracle," the water engineers were saying the huge storms that broke that drought cycle weren't enough.

 

That the rain was falling mainly on the plain - i.e. here in Southern California - instead of as snowpack up north. They were blaming Mother Nature for their own Rube Goldberg-like rainwater collection systems.

 

That was then. Now, there's more storage and more water saving.

 

We give the water folks credit. They've built in more water conservation by flooding the market with low-flow toilets and low-flow showers. Giveaways have been common at many water agencies. In the last 15 years, MWD and others have invested in some extensive water storage systems, both above and under ground. This has increased water storage here in Southern California. MWD reports it currently has 2.5 million acre-feet in surface and groundwater storage accounts, including Diamond Valley Lake in Perris. During the last drought, Southern California had just 225,000 acre-feet of water stored at one time. (One acre-foot of water equals 326,000 gallons, about what's used by two families in a year).

 

In addition to that new reservoir, underground basins like those in the Chino and San Gabriel valleys are being cleaned up. That means more local water can be stored underground and less water is imported from Northern California or the Colorado River.

Better water collection systems, combined with more water conservation and water recycling, will sustain life in our region. And oh yeah, occasional gifts of rain from Mother Nature.  #
