SOUTHERN CALIFORNIA WATER SUPPLY PROJECTIONS:

Officials: Wet January won't solve water issues;

 

While Southwest County received just about as much rain in January as fell in all of 2007, water officials say it is still not enough to make up for recent dry years.

Temecula, for example, recorded 7.36 inches of rain last month, compared with 7.94 inches in calendar year 2007.

 

The rainfall season runs from July through June and Temecula already has experienced more than 13 inches of rain this season while receiving just 3.75 inches during the 2006-07 season.

 

Such higher recent rain totals are driving down demands for water, but "we are still facing some issues," Bob Muir, spokesman for the Metropolitan Water District of Southern California, said recently.

 

"We are hoping for the best and hope the rain keeps coming," he said.

"We have seen drops in demands as much as 20 percent" from member agencies, Muir said.

The Metropolitan district is a consortium of 26 cities and water districts that provides drinking water to nearly 18 million people in Southern California, averaging deliveries of 1.7 billion gallons of water each day over a 5,200-square-mile area, which includes some of Riverside County.

"We have to remember that about half the water we rely on comes from the Colorado River and Northern and Central California," Muir said.

And there are issues in those areas, according to state water officials.

California's Department of Water Resources points out on its Web site that 2007 was a dry year across the state, especially in Central and Southern California. The Colorado River Basin also continued to experience drought conditions last year and has had a below-average runoff in seven of the last eight years, according to the Web site.

While there have been concerns with water shortages, one dry year is not enough to constitute an actual drought, the department states. The last major statewide drought was 1987 through 1992, and the last drought in Southern California was 1998 through 2002, according to the state agency.

The Department of Water Resources issued a news release Monday that described an increase in its allocation of 2008 State Water Project water for long-term contractors from 25 percent to 35 percent of their requests.

The State Water Project is a series of reservoirs, dams, pipelines and pumping stations that deliver Northern California water to the rest of the state. The project, which runs from Plumas County in northeastern Californian and ends in Riverside County, includes the 444-mile California Aqueduct.

The Metropolitan Water District is one of the long-term contractors with the Department of Water Resources.

"We can credit a wetter-than-average January for an impressive increase in our water supplies and snowpack," DWR Director Lester Snow states in the release. "However, tighter pumping restrictions in the (Sacramento-San Joaquin) Delta will limit how much of this water we can actually provide to many parts of Southern California."

Those restrictions come after a federal court last year limited pumping in the delta to protect the delta smelt, a small slender-bodied fish. The smelt was listed by both state and federal officials as "threatened" in 1993, according to the California Department of Fish and Game.

Without that court action in place, the Department of Water Resources estimates that the 35 percent allocation announced Monday would be more like 50 percent, meaning more water would be available.

Timothy F. Brick, chairman of Metropolitan's board of directors, recently commented on the State Water Project's delivery reliability report, which was released late last month.

"This sobering assessment of the state's water situation serves as a reminder that, despite the recent rains, the problems in the Sacramento-San Joaquin Delta remain unresolved," Brick said.

"We face a new reality in Southern California that will require conservation each and every year in order to keep our supplies and demands in balance," he added.

Metropolitan officials continue to ask everyone to be smart in their water use ---- to conserve voluntarily.

"We are telling people to cut back and use common sense, like turning off sprinklers when it rains," Muir said.

With some very dry periods during the last eight years, he said, challenges remain for this year and beyond.

"A drop saved today is a drop that can be used later," Muir said.

Even with the heavy rains in January, that doesn't mean this will continue to be a wet season, according to officials.

Climatologists with CalTech's Jet Propulsion Laboratory in Pasadena say that rainfall in Southern California could be 20 percent below average by the end of the rain season.

Ivory Small, a National Weather Service meteorologist, said earlier this week that their three-month outlook predicts a "slightly below normal" amount of rain for Southern California.

January, traditionally, "can be a very, very wet month," Small said.

He cited January 1998 when El Nino conditions brought significant rainfall.

Last month, according to Small, the heavy rain came because the jet stream that typically "meanders around" instead decided to come right through Southern California.

"It doesn't take long to get (rainfall) numbers up when that happens," he said. "That can happen when the jet is this strong."

As of now, February has not started out as wet as January was.

The jet stream is staying to the north, Small said, so there is no rain predicted for the area for at least the next week. #

Editorial: Drought foresight?

Riverside Press Enterprise – 2/7/08

 

California faces short- and long-term challenges in securing a sufficient water supply, and the state cannot count on approaches that worked in the past. Addressing those needs requires moving past old political disputes -- and making changes in behavior and outlook.

 

Those changes should start in the Legislature, which has let disagreement over new dams stall progress on water issues again this year. But that battle revisits old controversies instead of looking to future needs -- and the partisan standoff does nothing but make the state's water situation more precarious.

 

The most immediate legislative need is a plan to safeguard the state's primary water supply. Two-thirds of California's population and 3 million acres of agriculture depend on water that comes through the Sacramento-San Joaquin Delta.

 

But environmental concerns prompted a court ruling last year slashing water exports from the delta.

 

The state also needs to focus on the broader water picture. Two studies published in the journal Science last week outlined changes in weather patterns that will have profound consequences for the Western United States.

 

One report found that human activity, including rapid growth in the Southwest, had contributed to a steadily warming and drier climate, less winter snowpack and reduced water flows over the past five decades. The second study warned that water planners will have to adjust to greater variation and unpredictability in climate.

 

The grim outlook: California cannot rely on winter snows to store water for the dry summer months. The West will get less snow and more rain from winter storms, and the snow will melt earlier. The change would raise the danger of winter flooding, while overwhelming a water system geared to a different precipitation cycle, and increase the chances of summer shortages.

 

The climate changes represent long-term trends. Californians should not let the recent rains and the above-normal winter snowfall this year lull them into complacency.

 

These and previous studies suggest that California cannot retain old water habits. The state will need to collect and store more winter storm runoff, instead of focusing on preventing storm-driven floods, for example. That will require new agreements on water rights, additional storage facilities and new flood control projects.

 

And California should focus on better use of existing water supplies, through increased conservation and recycling.

 

More efficient water use will require changes in building codes, improvements in aging water systems and even alterations in personal habits.

 

Such policy and social shifts will take extensive cooperation by federal, state and local agencies, businesses and residents. The future requires changes -- and a partisan impasse offers a poor foundation for building a better state water policy.  #

Response to article “Pass area storms (3 more inches of rain) (Feb. 1) put a dent in the drought” – 2/8/08

By John Jeter, President San Gorgonio Pass Water Agency

 

Your front page article “Pass area storms (3 more inches of rain) (Feb. 1) put a dent in the drought” caught my attention. The article concludes “The California drought appears to be waning ... ”

While the recent storms have certainly added to our local water supplies and have also reduced water demand, it is far too early to declare that our drought is “waning.”

Consider the fact that the Colorado River is in the ninth year of a drought, the longest drought on record in that watershed. The two major reservoirs on the Colorado, Lake Meade and Lake Powell, are about half full and falling fast.

As of this writing, the State Water Project's allocation for 2008 is only 25% (it was 60% last year). The two major reservoirs in the State Water Project system, Lake Oroville and San Luis Reservoir, are both less than half full. The California Department of Water Resources has already stated that San Luis Reservoir, which is strategically located south of the Sacramento Delta, will not be filled this year.

A federal judge's ruling last summer on an endangered fish has cut exports from the Delta to Southern California and the Central Valley, and threatens several years of court-mandated water shortages ahead.

The Metropolitan Water District of Southern California, the largest water agency in the state, has stated that, while it previously could count on increasing storage in its local reservoirs seven years out of every ten, due to the court decision it now expects to be able to add to storage only three years out of ten, while withdrawing from storage or breaking even the other seven years.

 

 

The Beaumont groundwater basin, the largest local source of supply, is still in a state of overdraft. In 2005, for example, the last year for which detailed numbers are available, withdrawals from the basin totaled 13,670 acre-feet, more than twice the estimated safe yield of the basin. In the three years prior to that, withdrawals were even higher, averaging over 18,000 acre-feet per year. Water levels in the basin are still dropping.

We are all grateful for the recent storms and their impact on our water supplies. However, we must still be diligent about water use and practice good water conservation measures. Many water experts are predicting water shortages this summer in many parts of Southern California. While the California drought will no doubt start to wane someday, that day is not now. #
