Water and agriculture go hand in hand. Growing food for the planet’s people consumes 70 percent of its freshwater sources. Therefore, water is not only life-giving, it is life-sustaining. Yet with climate change, population growth and development on watersheds, an estimated 2 billion people globally face limited access to clean water. And demand for water is expected to grow by 30 percent globally by 2050.
If Lt. Gov. Gavin Newsom is elected governor as expected, he’ll keep building the state’s two contentious public works projects: the bullet train and twin water tunnels. But he’ll scale back both. He’ll be more cautious, realistic and practical about the super-expensive projects than termed-out Gov. Jerry Brown.Newsom will concentrate on completing a high-speed rail line from the San Joaquin Valley to the San Francisco Bay Area.
The likelihood this winter of an El Niño — the weather pattern marked by warm Pacific Ocean waters that can affect California’s rainfall — is increasing. The probability of El Niño conditions being present by December is now 70 to 75 percent, up from 50 percent five months ago, according to a new report Thursday from the National Oceanic and Atmospheric Administration. But so far, this El Niño looks more like a lamb than a lion.
For the first time in decades California may see construction of new water storage. The legislation would pay for new water storage projects as part of America’s Water Infrastructure Act of 2018. It now goes to President Trump to sign it into law after the U.S. Senate approved the measure yesterday. The legislation provides financing for water projects throughout the western U.S. including new reservoirs, below ground storage, and desalination projects.
The latest report from the National Oceanic Atmospheric Administration (NOAA) indicates an increased likelihood of El Niño conditions being present by December. That’s right. It seems we have a 70 to 75 percent chance of a wet winter, this year. The most recent report shows warming ocean temperatures in the Pacific, which is a precursor to a more southern track of the jet stream.
October 1 is New Year’s Day for water in the U.S. west. This year, Californians were bidding farewell to a dry 2018 water year (October 2017-September 2018), which saw precipitation totals fall below the annual average for much of the state. The return to drier than average conditions was a let-down following an extremely wet water year in 2017 that had helped bring about drought relief.
Groundwater depletion is a big problem in parts of California. But it is not the only groundwater problem. The state also has many areas of polluted groundwater, and some places where groundwater overdraft has caused the land to subside, damaging roads, canals, and other infrastructure. Near the coast, heavy groundwater pumping has caused contamination by pulling seawater underground from the ocean.
If temperatures increase in California because of climate change, snow could melt earlier in the Sierra Nevada — and you might only find it at higher elevations. In a study released this week a UC Irvine team found that if winter temperatures increase by 1 degree Celsius, it will lead to a 20 percent jump in the likelihood of below-average snow accumulation in the high country.
There’s going to be a new governor in California next year – and a host of challenges, both old and new, involving the state’s most vital natural resource, water. So what should the next governor’s water priorities be? That was one of the questions put to more than 150 participants during a wrap-up session at the end of the Water Education Foundation’s Sept. 20 Water Summit in Sacramento.
California voters may be feeling a sense of deja vu when they consider Proposition 3, an $8.9 billion water bond on the November ballot to fund a long list of water projects — from repairing Oroville Dam to restoring Bay Area wetlands to helping Central Valley farmers recharge depleted groundwater. Didn’t the voters recently approve a big water bond? Maybe two of them? Yes. And yes.
