What if farmers could use half the water than they are now without sacrificing crop yield?
Arizona would be a different place.
There are roughly 946,000 acres of farmland in the state, according to the most recent federal farm census in 2018, using an estimated 4.4 million acre-feet of water.
The term La Niña may be one that casual weather observers as well as aficionados hear meteorologists using from time to time, especially when breaking down long-term weather trends or providing a sneak peek at conditions expected during an upcoming winter or hurricane season. But, what exactly is La Niña? Let’s take an in-depth look.
The key to how winter in the United States may unfold often lies thousands of miles away in the open waters of the equatorial Pacific Ocean. It’s there where the roots of a climatological phenomenon known as La Niña originate and eventually help shape weather patterns worldwide.
With snowpack and storage at historic lows, California and 95% of the West are suffering the worst drought in modern history. Marin and Santa Clara counties have imposed mandatory cutbacks, and other counties are considering the same. However painful, it is time for California to move quickly. Here are the steps — starting with the least intrusive and least expensive — that state and local government need to take now to avoid the dystopia that Cape Town, South Africa, endured in 2018 when the faucets ran dry.
Happy New Water Year. For those of us who work on California water challenges, the start of the new year isn’t Jan. 1; it’s Oct. 1, the official beginning of the state’s wet season. This is the time of year we start to look out over the Pacific for the storms we hope will bring life-giving precipitation, replenishing our rivers and streams, coating our mountains with snow, refilling our reservoirs and recharging our soils, forests, wetlands and groundwater.
Northern California receives more annual rain and snow than Southern California, with 75% of the state’s precipitation falling in the watersheds north of Sacramento. Yet amid a drought, it seems people in the north are conserving water by letting their lawns turn brown and taking shorter showers as districts and municipalities impose mandatory water-use restrictions, while urban areas of the arid south are lush and green with well-watered gardens and lawns.
California’s reservoirs are so dry from a historic drought that regulators warned Thursday it’s possible the state’s water agencies won’t get anything from them next year, a frightening possibility that could force mandatory restrictions for residents. This year, unusually hot, dry conditions caused nearly 80% of that water to either evaporate or be absorbed into the parched soil — part of a larger drought that has emptied reservoirs and led to cuts for farmers across the western United States. It caught sate officials by surprise as California now enters the rainy season with reservoirs at their lowest level ever.
The first-ever official shortage on the Colorado River has intensified a debate over how to provide water for 40 million people across the Southwest and irrigate fields of thirsty crops like wheat, cotton and alfalfa. Few voices outside government are more influential than that of the Walton family, billionaire heirs to the Walmart Inc. fortune, who have long advocated water markets as a key part to solving the region’s woes. But some environmental groups say the Waltons drown out other, nonmarket approaches.
With California’s extreme drought persisting and reservoirs declining to new lows, state officials said they will consider imposing mandatory water restrictions if dryness continues this winter. Gov. Gavin Newsom called on Californians in July to voluntarily reduce water use by 15%, saying state water regulators would track progress toward that target and decide whether additional measures would be necessary.
The storage level in Lake Mendocino was on pace to drop below 15,000 acre feet on Saturday, meaning a quarter of the supply water managers had hoped to keep in store by Oct. 1 already has been released. The rapid shrinkage of the reservoir after two years of historic drought raises unsettling questions about the future for a range of consumers along the upper Russian River, whose supplies already are heavily restricted.
On September 28, 2021, the state of California (through the Office of Environmental Health Hazard Assessment) held a virtual workshop for proposed Public Health Goals (PHGs) for two types of PFAS – PFOA and PFOS. The release of proposed PHGs is extremely significant for any company situated in California, as PHGs are used to create enforceable drinking water standards and limits for groundwater contamination.
