A second straight wet winter may be in store for California, but state water regulators are turning their attention to the prospect of long-term water shortages, with plans for permanent statewide restrictions.
Current El Niño conditions appear likely to become comparable to the “great” El Niño of 1997-98, according to an experimental prediction system used by the National Science Foundation’s National Center for Atmospheric Research.
“Our forecast system has shown that it can do a remarkably good job of accurately hindcasting past El Niño events when we’ve tested it using historical data, which gives us high confidence in this forecast,” said NCAR scientist Stephen Yeager, who helped lead the modeling effort.
The Southwest monsoon has wrapped up, and it featured a weird split of record dry conditions in parts of Arizona and soaking rain, including from the remnants of a former hurricane in California, Nevada and other states.
To understand where you’re going, you have to know where you’ve come from. That’s the idea researchers were pursuing with the recent geochemical analysis of a single stalagmite from a cave in Grand Canyon National Park.
More specifically, they measured the ratio of stable isotopes in calcite deposits within the stalagmite to help predict how the volume of groundwater aquifers may be affected by a warming climate.
Colorado River officials plan to expand a conservation program next year that pays farmers and ranchers to use less water. But questions remain about some of the proposed ideas and the program’s overall efficacy.
The state initially launched the System Conservation Pilot Program in 2015 as a part of a multistate effort to conserve water from the Colorado River, which provides water for millions of residents throughout seven states as well as Mexico. The effort was designed to see if conservation efforts could stabilize the water levels in critical reservoirs along the river, like Lake Powell.
An El Niño winter is ahead, weather forecasters firmly believe. The question they are pondering is exactly how strong it might be.
Locally, the worldwide weather factor is mostly known for directing heavy moisture toward California and the Southwest as temperatures warm several degrees across the eastern and central Pacific Ocean.
Sept. 30 marks the end of a water year to remember in California.
With the new water year kicking off Oct. 1, it’s worth looking back at the water year that was from record snowfall to landfalling tropical storms and everything in between.
For years, conversations about the Sustainable Groundwater Management Act – known commonly as SGMA – have largely taken a tone of speculation and even apprehension.
The 2014 law, which aims to slow California’s unlimited tapping of underground aquifers, gives locally organized groundwater sustainability agencies until 2042 to overhaul pumping practices for the spectrum of groundwater users — from cities and rural communities to dairies, small farms and agricultural conglomerates.
Less than two months since Mammoth Mountain’s historic ski season concluded, the first snowfall of the new season is set to arrive in the Sierra Nevada.
Weather models predict a low-pressure system with Canadian roots will bring cool temperatures and rain showers to the California coast and Central Valley on Saturday. In the Sierra Nevada, the air is expected to be cold enough for the first snowfall of the season at Kirkwood Mountain, Mammoth Mountain and other high-elevation ski resorts.
The Colorado River crosses seven states and Mexico and is 1,450 miles long – the sixth longest in the nation according to river conservation organization American Rivers. More than a natural spectacle, the river supplies drinking water for one in 10 Americans and just half of the river water nourishes nearly 90% of the nation’s winter vegetable crops.
