Livermore: Wet winter helps replenish groundwater supplies

March 21, 2019

“With our streams and rivers running fast and high and all the snow piling up in the High Sierra, it certainly looks like California is well out of the drought, but what about beneath the surface?

“Right now our basin, fortunately, is at 98 percent full,” said Carol Mahoney, Manager of Integrated Water Services for Zone 7, the water supply and flood control agency that serves Livermore and the Amador Valley. … ”

Owens Valley Groundwater Authority mulls budget

March 21, 2019

“After skipping its February meeting to figure out staffing, the Owens Valley Groundwater Authority had a chance to mull over its draft budget for this fiscal year.  This budget takes into consideration some unknowns when the initial budget was developed prior to the official formation of the Authority.

The biggest unknown was the grant application to cover the consultant’s cost to come up with a Groundwater Sustainability Plan. The OVGA got the grant and will now use member contributions to cover staff and other miscellaneous costs. … ”

Bill Patzert says not so fast with declaring drought over; groundwater recovery could take years

March 20, 2019

“We’re having one of the best rainfall seasons in years, with drought conditions easing for much of the state.  But one of the nation’s leading oceanographers says there’s much more involved before the impacts of the drought are completely gone, and that it could take years to replenish groundwater supplies.

Former NASA oceanographer Dr. Bill Patzert says while we had the possibility of El Nino conditions going into the rainfall season, which could have magnified rain amounts, it didn’t happen. Patzert says El Nino was “El No-Show”. … ”

ASU scientists using latest space technology to assess the health of a large aquifer system in California’s San Joaquin Valley

March 20, 2019

“A team of Arizona State University scientists has been using the latest space technology, combined with ground measurements, to assess the health of one of the nation’s most important sources of underground water, a large aquifer system located in California’s San Joaquin Valley.

The team, comprised of School of Earth and Space Exploration researchers Chandrakanta Ojha, Susanna Werth and Manoochehr Shirzaei, focused on the San Joaquin Valley’s most recent drought period, from 2012 to 2015, measuring both groundwater loss and aquifer storage loss. The results of their findings have been recently published in the Journal of Geophysical Research. … ”

Is U.S. Groundwater Quality Getting Better or Worse? It’s Hard to Say

March 15, 2019

“After nearly three decades of groundwater monitoring, the federal government’s foremost Earth science agency has collected enough data to begin identifying long-term pollution trends in the country’s largest aquifers.  A few trends, that is, but not many.

Two clear patterns that the U.S. Geological Survey’s National Water Quality Assessment found are that concentrations of chloride and sodium are climbing nationally, while in farm regions in California and southern Georgia, nitrate levels have increased. … ”

Friant Water Authority: FWA: Strathmore flooding not the result of canal subsidence or overflow

March 14, 2019

“The Friant Water Authority Tuesday morning issued the following statement regarding the flooding in Strathmore last weekend with the hope of clearing up some possible misunderstandings as to the cause of the flooding:

“The flooding experienced in a residential neighborhood in Strathmore near the Friant-Kern Canal over the weekend is not due to overtopping of the Friant-Kern Canal’s banks — which did not occur — and is also not related to subsidence problems or conveyance restrictions on the Friant-Kern Canal, but rather to drainage from Frazier Creek. The Friant-Kern Canal’s integrity has not been compromised. … ”

Paso Robles groundwater committee seeks public input on supply projects, pumping fees

March 14, 2019

“North County political leaders responsible for the health of the Paso Robles Groundwater Basin are launching discussions about which multi-million-dollar water projects could help solve the aquifer’s woes—and how basin pumpers will pay for them.

In the future, the basin, which serves much of Paso Robles wine country, could start receiving water from the State Water Project, Lake Nacimiento, and/or the Salinas Dam. … ”

The challenges of changing land use in the San Joaquin Valley:

March 12, 2019

 “Implementing the state’s Sustainable Groundwater Management Act—which requires overdrafted groundwater basins to achieve balance between supply and demand by the 2040s—could require taking at east 500,000 acres of irrigated cropland out of production in the San Joaquin Valley.

While some lands will be converted to uses such as solar energy, groundwater recharge, and restored habitat, there are no current plans for most of this acreage. We talked to Soapy Mulholland, president and CEO of Sequoia Riverlands Trust, about this impending challenge.

PPIC: What key challenges does this land use transition pose?

Soapy Mulholland: The challenges of managing this amount of land if it’s fallowed piecemeal―5 acres here, 30 there—are huge. A hodgepodge of retired lands would be very difficult to manage and restore. … “

A winning approach for managing groundwater in the San Joaquin Valley

March 12, 2019

Alvar Escriva-Bou, Ellen Hanak, and Josué Medellín-Azuara write,

“The San Joaquin Valley is in a time of great change. Decades of groundwater overuse have caused drinking water and irrigation wells to go dry, increased the amount of energy required to pump water, harmed ecosystems, and reduced the reserves available to cope with future droughts.

Groundwater overdraft has also caused land to sink, damaging major regional infrastructure, including canals that deliver water across the state.  These problems spurred the enactment of the Sustainable Groundwater Management Act (SGMA), which requires local water users across California to bring groundwater use to sustainable levels by the early 2040s.

With California’s largest groundwater deficit, the San Joaquin Valley is ground zero for implementing SGMA. … ”
