Most of the native habitat in California’s San Joaquin Desert has been converted to row crops and orchards, leaving 35 threatened or endangered species confined to isolated patches of habitat. A significant portion of that farmland, however, is likely to be retired in the coming decades due to groundwater overdraft, soil salinity, and climate change. A new study … found that restoration of fallowed farmland could play a crucial role in habitat protection and restoration strategies for the blunt-nosed leopard lizard and other endangered species.
An ambitious new multicampus, multipartner consortium led by the University of California, Davis, and the UC Working Lands Innovation Center is taking on that challenge with the goal of finding ways to capture billions of tons of carbon dioxide and bring net carbon emissions in California to zero by 2045. The consortium has received a three-year, $4.7 million grant from the state of California’s Strategic Growth Council to research scalable methods of using soil amendments — rock, compost and biochar — to sequester greenhouse gases like carbon dioxide in soil.
Land subsidence from overpumping of San Joaquin Valley groundwater sank portions of the Friant-Kern Canal, the 152-mile conduit that conveys water from the San Joaquin River to farms that help fuel a multibillion-dollar agricultural economy. A plan to fix it helped sink the $8.8 billion Proposition 3 bond measure last November. Now San Joaquin Valley water managers are trying to figure out another way to restore the canal, not only to keep farmers farming, but to aid the valley’s overtaxed groundwater aquifers.

A simple web search will pull up nearly a million articles, videos and photos featuring Frank Gehrke. He’s no fashion icon like Kim Kardashian or a dogged politician like Gov. Jerry Brown. But he has broken a lot of news. … For 30 years, you might have seen Gehrke on TV, the guy trudging through snow with a measuring pole, talking about how deep the pack is each winter on the evening news. He retired from his post as the state’s chief snow surveyor in December, but he’s not letting go of his snowshoes and skis anytime soon.
Far less settled is how Newsom will fill his administration’s most important positions regarding state water policy. One of Newsom’s key tests confronts him immediate: State Water Resources Control Board Chair Felicia Marcus’ term expires this week.
The California Department of Fish and Wildlife (CDFW) today released the Delta Conservation Framework as a comprehensive resource and guide for conservation planning in the Sacramento-San Joaquin Delta through 2050. The framework provides a template for regional and stakeholder-led approaches to restoring ecosystem functions to the Delta landscape.
The draft legislation compiled by the Department of Water Resources looks similar to how water leaders described the measures at a Drought Contingency Plan Steering Committee meeting last week. … But the legislation as drafted barely delves into the nitty-gritty details of a far more complex intrastate agreement that Arizona water users have been hashing out for months.
The confluence of California’s two great rivers, the Sacramento and the San Joaquin, creates the largest estuary on the West Coast of the Americas. Those of us who live here call it, simply, the Delta. It is part of my very fiber, and it is essential to California’s future. That’s why we must save it.
After more than three years, 104 days of testimony, and over twenty-four thousand pages of hearing transcripts, the hearing before the State Water Resources Control Board (State Board) on the proposal to construct two tunnels to convey water under the Delta (aka California WaterFix) is almost completed. Probably, that is: there could be more if the project changes again to a degree that requires additional testimony and/or environmental review.
Wells are going dry and there are few long-term solutions available — a common stopgap has been to drill deeper wells. This is exactly what happened in California’s Central Valley. The recent drought there prompted drilling of deeper and deeper water wells to support irrigated agriculture. Groundwater supplies around the world are being threatened by excessive pumping, but drilling deeper wells is not a long-term solution. A better solution is to manage water use and avoid excessive declines in groundwater levels.
Learn from top experts at our annual Water 101 Workshop about the history, hydrology and law behind California water as well as hot topics such as water flows, the Delta, disadvantaged communities and the Sustainable Groundwater Management Act. For the first time, the workshop offers an optional groundwater tour the next day
The McCormack-Williamson Tract restoration project, a 1,500 acre site, lowers the levees on the north side of the island to allow the river to overtop into the site. On the south side, DWR will alleviate the surge flows that pose a risk to neighbors by opening small holes in the levee. 2018 saw the completion of construction of a levee to protect existing infrastructure on the site, as well as progress on habitat restoration plans. For the next phase, DWR will strengthen the interior levees and take steps toward opening the site up to tidal flows.
Following one of the hottest and driest years on record, the Colorado River and its tributaries throughout the western U.S. are likely headed for another year of low water. That’s according to a new analysis by the Western Water Assessment at the University of Colorado Boulder. Researcher Jeff Lukas, who authored the briefing, says water managers throughout the Colorado River watershed should brace themselves for diminished streams and the decreasing likelihood of filling the reservoirs left depleted at the end of 2018.
A proposed Colorado River drought plan that will cost well over $100 million is just the beginning of what’s needed to protect the over-allocated river, says Bruce Babbitt, the former governor who rammed through Arizona’s last big water legislation nearly four decades ago. After Gov. Doug Ducey urged legislators to “do the heavy lifting” and pass the proposed drought-contingency plan for the Colorado, Babbitt said Monday that authorities will have to start discussing a much longer-term plan immediately after it’s approved.
Arizona legislators and staff are attending closed-door primers on water policy in advance of a critical January 31 federal deadline for the state to approve the Drought Contingency Plan. The first of three meetings occurred on Friday afternoon and lasted two and a half hours. The session was led by Central Arizona Project general manager Ted Cooke and Arizona Department of Water Resources Director Tom Buschatzke.
Gov. Gavin Newsom, if he is to successfully steer the state into the future, has to bring to his water agenda the same steely-eyed, reality-based drive that the two previous governors brought to limiting carbon emissions. It is time for the state to respond to its water challenge with the same sense of urgency with which it adopted Assembly Bill 32, the landmark law capping greenhouse gas emissions, in 2006.
In an attempt to block the state’s plan to divert more water toward the Sacramento-San Joaquin River Delta and away from the Bay Area, the Santa Clara Valley Water District has filed a lawsuit arguing the project could significantly reduce the local water supply. If the plan advances, the water district might have to spend millions of dollars to obtain alternate water supplies and pull up more groundwater.
California began 2019 with lower-than-average snowpack measurements — just 67 percent of the year-to-date average. Recent storms pushed that total to 90 percent as of Friday. With more precipitation on the horizon, forecasters predict snowpack measurements will “meet or exceed” the year-to-date average by the end of the week.
Specific details have not yet emerged on Newsom’s plan, but it’s expected to be similar to a rejected 2018 proposal from state Sen. Bill Monning, D-Carmel, to tax residential customers 95 cents a month to help fund water improvements in rural farming communities in the Central Valley and throughout the state. It would raise about $110 million to get clean water to what the McClatchy News Service estimated last year to be 360,000 people without such access. Others looking at the problem see it as much worse.
