The city of San Diego and East County leaders have resolved a months-long dispute over a planned water recycling project, heading off a potentially expensive court fight over what to do with the plant’s waste.
Scientists have discovered that the pace of groundwater depletion in California’s Central Valley has accelerated dramatically during the drought as heavy agricultural pumping has drawn down aquifer levels to new lows and now threatens to devastate the underground water reserves. The research shows that chronic declines in groundwater levels, which have plagued the Central Valley for decades, have worsened significantly in recent years, with particularly rapid declines occurring since 2019.
On a crisp day this fall I drove southeast from Grand Junction, Colorado, into the Uncompahgre Valley, a rich basin of row crops and hayfields. A snow line hung like a bowl cut around the upper cliffs of the Grand Mesa, while in the valley some farmers were taking their last deliveries of water, sowing winter wheat and onions. I turned south at the farm town of Delta onto Route 348, a shoulder-less two-lane road lined with irrigation ditches and dent corn still hanging crisp on their browned stalks. The road crossed the Uncompahgre River, and it was thin, nearly dry.
With climate change and drought, the state of California is incentivizing not using farmland or fallowing it. The move comes as irrigation in some areas is damaging residential wells. Katie Staack farms 3,500 acres of almonds in Stanislaus County. She is one of the hundreds interested in the newly created LandFlex program. “The program is really unique because it’s focused on wet water, making sure we have wet water for our communities and aquifers, our ecosystems and farms,” Aubrey Bettencourt said.
The outskirts of Kingman, Arizona, used to be a place where pilots would train and recreationists tested their all-terrain vehicles. The dry and empty landscape has since morphed into something much more green that supports pistachio and almond orchards, and garlic and potato fields in a climate similar to California’s Central Valley. The crops are fed by groundwater that also serves the city of Kingman.
More than $63 million in proposed federal funding was announced Tuesday to support nearly two dozen projects across the San Diego region.
Sen. Alex Padilla, D-California, said in a statement that the Fiscal Year 2023 appropriations package that will deliver funding for 22 projects slated for the San Diego region will head next to both chambers of Congress for final passage.
Among the projects expected to receive funding in the package are:
— $3.45 million for the City of Oceanside‘s Loma Alta Creek Sewer Relocation, which will move a sewer main from a creek bed to a roadway to minimize environmental damage in the event of a sanitary sewer overflow.
— $3.45 million for the Smuggler’s Gulch Dredging Project, which will clear trash and sediment to protect downstream communities, and protect human and environmental health in the Tijuana River Watershed and coastal waters.
— $3.39 million for Borrego Water District‘s Borrego Spring Transmission Main, which will update the water distribution system and reduce water pipeline breaks.
— $3.06 million for the Valley Center Municipal Water District‘s Lilac Road Pipeline Replacement, which is aimed at reducing water loss and improving water conservation, among other benefits of the 60-year-old pipeline’s replacement.
A perfect combination of cosmic events will occur this holiday season to bring astronomically high tides known as king tides to San Diego just before Christmas, forecasters say. The phenomenon, which describes what are typically some of the highest tides of the year, are scheduled to occur on Dec. 23 and 24. A second round is predicted to happen on Jan. 21 and 22. The National Oceanic and Atmospheric Administration (NOAA) predicts that this winter season’s tides may cause coastal flooding in low-lying areas of San Diego.
A state board tasked with vetting water supply augmentation proposals for Arizona on Tuesday passed a nonbinding resolution in support of a potentially massive seawater desalination plant in Mexico’s Sea of Cortez. A partnership led by Israeli desalination specialists IDE Technologies pitched the multibillion-dollar plan to the Water Infrastructure Finance Authority of Arizona’s board, saying it could replace or complement declining Colorado River water that flows through the Central Arizona Project’s canal. The plant would remove salt from seawater and pump it north into the canal, where it would flow through Maricopa, Pinal and Pima counties.
As California is preparing for their fourth year of drought, the Bureau of Reclamation warns Central Valley Project water contractors of lessened water allocations. Two months after the start of the new water year on Oct. 1, the Shasta Reservoir, the state’s largest reservoir and cornerstone of the Central Valley Project (CVP), is currently at 31% capacity.
The cavalry is coming, so to speak, in the form of the U.S. Army Corps of Engineers, which entered into a feasibility study agreement with local and state government agencies to find shovel-ready solutions for saving the Salton Sea.
The significance of the collaboration was highlighted at a signing ceremony held at the North Shores Beach and Yacht Club near Mecca on Friday, Dec. 16, where the Salton Sea Authority, California Natural Resources Agency, California Department of Fish and Wildlife, and U.S. Army Corps of Engineers entered into the Imperial Streams Salton Sea Feasibility Cost-Share Agreement, which will develop and propose solutions to save the ever-receding Salton Sea.
