VALLEJO WATER SUPPLY:

Tiny delta smelt threatens AmCan water supplies?

AMERICAN CANYON - The statewide legal battle over the welfare of a tiny fish has American Canyon officials bracing for potential shutdowns of the pump that provides 80 percent of the city's water supply.

 

Although the pumping station that funnels water to North Bay cities has yet to be dragged into the conflict over the endangered Delta smelt, American Canyon Public Works Director Robert Weil said he is getting ready for potentially major - but temporary - cutbacks in next year's water supply.

 

"I reached the conclusion that it is prudent to be prepared for that contingency," he said Monday.

 

While many cities receive water from the North Bay Aqueduct fed by the Barker Slough pumping station, it would be particularly daunting for American Canyon, which receives nearly all its water supply from the state water project.

 

One of the first orders of business will be to craft an ordinance requiring residents to cut water consumption in case of an emergency, Weil said.

 

He also is preparing a plan that would include reduction of the city's own water consumption in parks and on landscaping.

 

American Canyon would also "maximize" the use of an agreement with Vallejo for more water supplies, he said.

 

Weil said the Public Works Department is preparing material designed to keep the public informed about the city's water situation.

 

"If and when this does happen, we will have a lot of communication out to the public to make them aware of it," he said.

 

The endangered Sacramento-San Joaquin Delta smelt has triggered lawsuits in state and federal courts because the water pumps often kill large numbers of the fish. The litigation led the state Department of Water Resources to temporarily shut down the Harvey O. Banks pumping plant near Tracy last month.

 

While the Barker Slough pumping station is much smaller, Napa County water officials believe a decision could be made to shut them down as well during the time of year when the migratory smelt are in the area.

 

"There has been no definitive statement to that effect but, just as the Delta woes continue to be looked at closer and closer, we certainly run that risk," said Felix Riesenberg, principal water resources engineer with the Napa County Flood Control District.  #

CENTRAL COAST WATER CONSERVATION:

Water conservation urged countywide; Officials in several communities are requesting that residents limit their water use after a particularly dry winter and spring; some mandatory measures may be ahead

San Luis Obispo Tribune – 7/3/07

By Nick Wilson, staff writer

 

Several communities are urging residents to conserve water after a light rainy season countywide, prompting some concern that stricter measures will be sought if the dry weather continues.

 

Some water users—particularly those in Nipomo, where rationing is being considered — could see mandatory conservation measures in coming months.

 

In Nipomo, the severity of the water shortage was affirmed last week by the county Board of Supervisors at Level 3 — the most critical — for the situation, at the request of the town’s services district. Nearly two weeks ago, Grover Beach became the latest local community to urge voluntary conservation. Council members expressed concern over rainfall that’s nearly 20 percent below last year’s total.

 

Among their guidelines: discouraging residents from using drinkable water for street cleaning; washing sidewalks, roads or driveways; as well as advising against using water for washing cars without a quick-acting shutoff nozzle on the hose.

 

City officials in Morro Bay and Atascadero have also been requesting their residents to conserve water.

 

Atascadero’s total use of water jumped this year to 2.25 billion gallons from 1.99 billion gallons, said John Neil, general manager of the city’s Mutual Water Co. He cited less rainfall and more dependency on water for irrigation.

 

And in Paso Robles, water conservation measures have been announced in a letter to customers and in public meetings because of the relatively dry year and possible rolling blackouts later this summer.

 

The North County city used 12 percent more water last year compared with this year, according to the Public Works department.

 

Rising rates

 

Although water rates are rising around the county, no increase appears to be directly related to the dry year.

 

Increases are under way in San Luis Obispo and Paso Robles to cover the costs of proposed supplemental Nacimiento Lake water; an increase is also under way in Grover Beach for water meter upgrades and other expenses.

 

Nipomo’s Level 3 severity was declared initially in December 2005 at the Nipomo Community Services District’s request.

 

The affirmation of the Level 3 declaration at a Tuesday meeting of the county Board of Supervisors was designed to make it easier to approve conservation measures.

 

A moratorium on new subdivisions outside the outskirts of town is being recommended by the county planning department staff until supplemental water is available.

 

Water levels in the Nipomo Mesa’s aquifer were 12 percent lower in April than a year before.

 

A further decrease of water in the district’s aquifers could allow saltwater to intrude, making some groundwater permanently unusable, officials say.

 

Groundwater is Nipomo’s only source of drinking water.

 

“It’s very likely that at some point the board will demand reduction and maybe rationing,” said Bruce Buel, the district’s general manager.

 

Several cities, including Morro Bay and Grover Beach, have procedures in place that allow city councils to impose mandatory water conservation by residents.

 

Conservation

 

Common requests that cities now are making of their residents include using drought-tolerant landscapes and cutting back on irrigation.

 

“There are some great drought-tolerant landscapes that aren’t rocks and cactus,” said John Neil, general manager of the Atascadero Mutual Water Co. “If people adjust their thinking, we’d really conserve.”

 

Neil — whose private firm supplies water to about 30,000 people in the Atascadero area —estimates about 50 percent of the water used gets “dumped on lawns.”

 

The company’s goal, he said, is not to have to dip into deeper groundwater sources because that’s harder on equipment and increases operational costs. The company pumps 8 million gallons of water per day.

 

“Since there wasn’t as much rain this year, we’ll be dipping into those deeper wells a little, but not significantly,” Neil said.

 

In Morro Bay, a widespread conservation effort has included rebates for people who install water-conserving fixtures on their toilets and washers, said Bruce Ambo, the city’s public services director. And the city has a communitywide leak detection system in its water lines.

 

“We’ve been pretty proactive about conserving,” Ambo said. “Folks have been pretty responsive.”  #

FOOTHILLS WATER SUPPLY:

El Dorado water supply called sufficient

Sacramento Bee – 7/3/07

By Cathy Locke, staff writer

 

Although the state Department of Water Resources has declared 2007 a "critically dry" year, El Dorado Irrigation District customers can expect adequate water supplies this summer.

 

The district serves nearly 100,000 residents in El Dorado County.

 

Staff members updated district directors last week on conditions for drinking water and power generation in the coming months.

 

They also presented the draft 2007 Water Resources and Service Reliability Report, which establishes the number of water meters available for construction.

 

The Sierra snowpack is about 20 percent of normal, but water stored from last year will help the district meet demands through 2007, said Sharon Fraser, an assistant engineer with the Drinking Water Division.

 

"If another dry year followed this year, it could constitute a drought," she said. #
