Cooperation Preserves Pauma Valley Groundwater

/in , /by

Instead of waiting for Yuima Valley’s precious groundwater supplies to dry up, the Yuima Municipal Water District and local farmers are working cooperatively to create a sustainable long-term strategy for maintaining the region’s economy and quality of life by proactively managing the valley’s aquifer.

To the east in Borrego Springs, the chronically water-short community offers a warning about over-tapping groundwater. Borrego Springs expects to face a 75 percent reduction in water supplies by 2040. The current plan is to let 3,800 acres of agriculture go fallow because farms use 80 percent of the community’s groundwater.

Yuima farmers also have relied on groundwater supplies for decades. Crops such as citrus and avocado flourish in the valley, nestled between Palomar Mountain and Valley Center.

But Yuima farmers want a different kind of future than they see unfolding in other groundwater-dependent areas of arid West.

Working with growers to sustain agriculture

Richard Williamson, general manager of the Yuima water district, is working with growers to sustain production and avoid groundwater depletion. When groundwater is pumped faster than it’s recharged, negative effects include reduced water quality, reduced surface water supplies, and land subsidence (or sinking).

“What we’ve tried to do is work on a program encouraging farmers to join our system,” Williamson said. “Many have been pumping wells on their property, and they know it will be curtailed in the future due to new laws protecting groundwater. They need to look to imported water to make up the difference.”

Yuima is among the smallest water districts in the region, covering 13,460 acres. Its 10 largest water users are all agricultural customers, consuming approximately 70 percent of total district water deliveries annually.

Facing increasing state regulations and increasingly hot summers, Williamson worked with farmers to find realistic, reliable, cost-effective strategies for his customers to keep their farms flourishing without 100 percent reliance on groundwater. Adopting a rate structure giving farmers lower pricing in exchange for flexible reliability is the key. The strategy allows the district to slow water deliveries to agricultural customers when imported water supplies are in high demand, similar to power companies offering reduced rates for interruptible service.

“There was a fair amount of discussion and education,” said Williamson. “Farming interests knew they had to come up with an alternative source of water to replace what they might not have in the future. They know it doesn’t serve anyone to draw the system down to nothing. They can look across this valley. All you see is green, citrus and horticulture being raised.”

Yuima agricultural water users try new program

Pauma Valley’s largest agricultural water user and a large avocado farm were the first to sign on. “It was a win-win situation,” said Williamson, “They still pump groundwater, but not as much as they used to. It will help everyone under the new groundwater regulations. Knowing it’s always available, they can set their watering patterns to meet the best efficiency from their water dollars as they possibly can.”

Now Yuima MWD is working to offer imported water supplies through the new program to additional farms by increasing system capacity.

“We currently have projects under way that will double our amount of imported water coming into the district,” said Williamson. “That will be done by 2020, so at that point it will coincide with these new regulations in place. We want to be ready with other agriculture interests. They are under the gun and need alternative sources of water.”

Williamson said so far, Yuima hasn’t faced water supply interruptions. “Because Pauma Valley is such a close-knit community, we will call our biggest users and warn them, ‘Things are a little tight, can you water at night or cut back watering time a little bit to get through this crunch?’ Everyone has been extremely cooperative with this idea.”

Williamson says the goal for his district is to remove the supply interruption provisions completely when capacity upgrades are completed in 2020.

“This valley is all about two things: agriculture, and Indian gaming. The tribes have indicated they don’t want to see agriculture hurt here. They feel it creates a really nice environment,” Williamson said. “This district takes a lot of pride being part of that environment. We want to be a positive influence, rather than wearing a black hat.”

 

 

 

Groundwater Policy Still Muddled Until Supreme Court Rules

/in , , /by /E&E Newsby Ellen M. Gilmer

A new EPA policy addressing pollution that moves through groundwater was intended to clarify the scope of the Clean Water Act but may serve to further complicate matters, at least in the near term.

Trump appointees released the memo last week, declaring that any pollutants that travel through groundwater before reaching a surface waterway are beyond the purview of the bedrock environmental law.

Oregon Directs Utilities To Show Plans For Accelerating Transportation Electrification

/in , /by /The Ulility Diveby Robert Walton

Oregon has aggressive clean transportation goals to go along with its renewable portfolio standard, but the state’s utilities will need to do some work in order to meet them. According to GEO, electric vehicles in Oregon are growing about 35% annually tHE which puts the state on pace to reach “just over 40,000 registered by 2020.” That means reaching 50,000 EVs in the next couple of years will require developing fast charging corridors along busy routes, developing “charge-ready” buildings and homes, and leaning heavily on utility partnerships, the group says.

By rejecting the twin tunnels proposal, Gov. Gavin Newsom has sent an important message that new thinking is required to address California’s complex water issues. The Delta Counties Coalition is committed to supporting a more thoughtful process. The Delta Counties Coalition represents more than 4 million residents whose livelihoods and way of life are grounded in a healthy Delta economy. The coalition serves to protect the largest estuary on the west coast of the Americas from unwarranted intrusion that could destroy the precious Delta ecosystem and hurt our region’s economy.

Spring Cleaning: Ways To Keep San Diego’s Water System Clean

/in , , /by /NBC 7 San Diegoby Ashley Matthews

All water leads to a recycling center so even it’s going down the drain, there are some things San Diegans can do to ensure our region’s water is as clean as possible. Water is always in high demand in California, so it’s necessary to take care of it in any way possible. The San Diego County Sheriff’s Department says one easy thing to protect the county’s waterways is to avoid dumping perscription pills. Tossing prescription medication down the drain or toilet contaminates the water system, which can cause bigger problems when it drains back into the ocean and threatens the environment, SDSO said.

California’s climate change efforts can be spotted all over the Bay Area in the growing number of electric cars and solar panels. But now, California is enlisting people from a more conservative part of the state  even if they don’t think climate change is much of a concern. California’s farmers are receiving millions of dollars to pull carbon out of the atmosphere, something the state says is crucial for meeting its ambitious climate goals.

Can Sensor Data Save California’s Aquifers?

/in , , /by /Futurityby Josie Garthwaite

In California, the amount of water exiting aquifers under the state’s most productive farming region far surpasses the amount of water trickling back in. That rampant overdraft has caused land across much of the region to sink like a squeezed out sponge, permanently depleting groundwater storage capacity and damaging infrastructure. The trend—and a 2014 mandate for sustainable groundwater management in the state—has ignited interest in replenishing aquifers in California’s Central Valley through managed flooding of the ground above them. But until now there has been no reliable way to know where this type of remedy will be most effective.

Westlands Officials Disappointed By Water Allocation Announcement

While all other Central Valley Project contractors’ allocations were previously increased to 100% of their contract totals in recent months, the Bureau of Reclamation announced Wednesday that agricultural districts South-of-Delta will receive only 65% percent of their historic water allocation. South-of-the-delta cities like Avenal that get water from the Central Valley Project were increased to 90 percent of their contract supply, up from an 80 percent allocation announced in March.
