Could the Answer to Groundwater Resources Come From High in the Sky?

Groundwater makes up 30 to 50 percent of California’s water supply, but until recently there were few restrictions placed on its retrieval. Then in 2014 California became the last Western state to require regulation of its groundwater. With deadlines starting this year, for the first time water managers in the nation’s premier agricultural region – the state’s Central Valley – are tasked with estimating available groundwater. It’s a daunting technological challenge.

California Assembly Passes Expedited Dam Safety for Silicon Valley Act

In an effort to move forward a $576 million Anderson Dam Seismic Retrofit Project, the California State Assembly passed AB 3005 on June 8, the Expedited Dam Safety for Silicon Valley Act, facilitating the construction of the project.

Assemblyman Robert Rivas (D-Hollister, Calif.), who wrote the bill, says the overwhelming vote of bipartisan support shows the importance in fixing the dam. “The clock is ticking on a catastrophic dam failure in case of a large earthquake,” he says, “and we can’t allow bureaucratic delay to increase risks to public safety, water security and environmental protections.”

City of San Diego in Dispute with SDG&E over Undergrounded Power Lines

The city government of San Diego is fighting with San Diego Gas & Electric over an ongoing project that replaces overhead power lines with underground lines in various parts of the city.

At issue is at least $22.1 million in invoices racked up from the end of 2018 through February of this year. City Attorney Mara Elliott says the price tag is too high and SDG&E has not properly documented the costs. The utility counters that it has substantiated its charges to city officials and the bill fairly represents work rendered.

Pure Water San Diego Projects Underway After Receiving Milestone Permit

Pre-construction activities at the North City Water Reclamation Plant and the future Pure Water Facility are underway as part of Phase 1 of the Pure Water San Diego program. More than 80,000 cubic yards of soil have been moved to date during initial site work, the equivalent of approximately 25 Olympic sized swimming pools.

Last month, the San Diego Regional Water Quality Control Board adopted an order granting a National Pollutant Discharge Elimination System, or NPDES permit, to the City of San Diego to add purified water to the Miramar Reservoir for Phase 1 of the Pure Water San Diego program. The approval is a major milestone for the program.

Delta Dispute Casts Shadow on Water Supplies

With supplies curtailed from California’s largest water projects, farmers have been reducing acreage, water districts have been working to secure additional supplies, and everyone has been keeping an eye on the continued dispute between state and federal governments on managing the delta.

Last month, the San Diego Regional Water Quality Control Board adopted an order granting a National Pollutant Discharge Elimination System, or NPDES permit, to the City of San Diego to add purified water to the Miramar Reservoir for Phase 1 of  Pure Water San Diego. The approval is a major milestone for the program.

NPDES permits contain discharge limits, monitoring and reporting requirements, and other provisions to ensure water quality and public health. The NPDES permit issued to the City is the first for a reservoir augmentation project in the state of California.

By implementing Phase 1, the City will be able to produce and store 30 million gallons per day of local water supplies and decrease its reliance on imported water.

Pure Water San Diego Phase 1 includes several projects

Phase 1 includes a series of pipelines and facilities to convey purified water to Miramar Reservoir. Adding the purified water to Miramar Reservoir will increase the reservoir’s beneficial use and optimize protection of water quality. The purified water will blend with the City’s imported sources and be treated again at the Miramar Water Treatment Plant and distributed to the public.

The purified water distribution area will include the portion of the City of San Diego that receives potable water from the Miramar Water Treatment Plant in addition to the City of Del Mar.

Phase 1 of Pure Water San Diego includes several projects: the Morena Pump Station and Pipelines, the North City Water Reclamation Plant Expansion, the North City Pure Water Facility, and the North City Pure Water Pump Station and Pipeline.

Central Valley Water Districts Take Aim at Each Other’s Groundwater Plans

There is no tougher playground than California’s water world.

Just take a look at the zingers flying back and forth between water districts on one another’s groundwater sustainability plans posted on the Department of Water Resources’ website.

“It’s like a giant game of dodgeball,” said Dana Munn, General Manager of Shafter-Wasco Irrigation District.

Study says Phoenix Reservoirs are Resilient to Warming, Scientists Warn Risks Remain

Scientists have found that climate change is playing a big role in shrinking the flow of the Colorado River, but recent research suggests Arizona’s reservoirs on the Salt and Verde rivers could fare better as temperatures continue to rise.

The findings back the assurances of water managers at Salt River Project that their system of reservoirs appears to be relatively resilient in the face of climate change.

The Great Divide: California Communities Battle for Rights to Water

An ongoing struggle between two communities less than a mile apart illustrates the challenges California faces as it tries to deliver clean, affordable drinking water to more than 1 million residents without access to what the state has called a “basic human right.”

Drought Fears Take Hold in a Four Corners Region Already Beset by the Coronavirus Pandemic

The vintage train was chugchugchugging its usual route out of Durango that sunny morning as tourists marveled at the postcard-pretty canyon. Just a few miles closer to Silverton, a plume of smoke started rising from the steep hillside.

Within minutes, a Good Samaritan tried to douse the flames, state and federal court documents say. Three separate efforts by the scenic railroad company—including one involving a helicopter—tried to put out the flames, too. But the fire burned out of control within minutes. By the time wildland firefighters finally extinguished the fire six months later, 54,000 acres, an area larger than the nearby Mesa Verde National Park, had been charred and recorded as Colorado’s sixth worst wildfire.
