There is a myth about water in the Western United States, which is that there is not enough of it. But those who deal closely with water will tell you this is false. There is plenty. It is just in the wrong places.
Deltas globally adjust with changes and fluctuations in external conditions, internal dynamics, and human management. This is a short history of big changes to California’s Sacramento-San Joaquin Delta in the past and present, and its anticipated future. This history is important for understanding how many of the Delta’s problems have developed, changed, and continue to change.
These days, the house where Donna and John Winters planned to retire in the Southern California desert reflects in a stagnant pool of blood red water, their dream home becoming something of a nightmare.
Wall Street’s reputation as one of America’s premier innovation machines can only be enhanced by a new futures contract that began trading publicly on Dec. 7. It allows investors to bet on the price of water in California.
Those who take the gamble are effectively betting that the spot price for water will rise during the life of the contract; they’ll pocket the difference. Sellers are betting that the price will fall.
Beside a river that winds through a mountain valley, the charred trunks of pine trees lie toppled on the blackened ground, covered in a thin layer of fresh snow. Weeks after flames ripped through this alpine forest, a smoky odor still lingers in the air.
The fire, called the East Troublesome, burned later into the fall than what once was normal. It cut across Rocky Mountain National Park, racing up and over the Continental Divide. It raged in the headwaters of the Colorado River, reducing thick forests to ashes and scorching the ground along the river’s banks.
A dry start to California’s water year is reflected in the season’s first snow survey of the Sierra Nevada snowpack. The statewide snowpack is 52% of average for Dec. 30. On average, the Sierra snowpack supplies about 30% of California’s water needs.
“The first snowpack survey of the water year points to California’s climate variability, which is why a diverse water portfolio is needed to provide a reliable supply,” said Goldy Herbon, San Diego County Water Authority senior water resources specialist. “The Water Authority and its 24 member agencies have successfully diversified water sources, and continue to expand those sources, to ensure our supply meets the needs of the region’s 3.3 million people and its $245 billion economy.”
Yes, it’s been pretty dry so far this winter, but there is no need to worry. The major winter storm that roared through Southern California Monday proved we can erase a month’s worth of rain deficit in one day. I recently explained how the climate where we live — the Mediterranean Climate — sees the majority of its annual rainfall in the winter months. In fact, a whopping 80% of Southern California’s annual rain and snow falls from December through March.
One of the best road trips I’ve ever taken was a sightseeing tour of the Colorado River, where it straddles the California-Arizona state line. I stood at the edge of Imperial Dam near the Mexican border, which diverts water to the farm fields of the Imperial Valley, then drove north to Cibola National Wildlife Refuge, home to lots of birds. I walked along the river in Laughlin, Nev., where there’s a hotel called the Colorado Belle that looks like a boat, and in Needles, Calif., where Snoopy’s brother Spike lives.
Extreme weather will surely have its own chapter in the turbulent history of 2020. The human and economic toll of Covid-19 was already enormous this fall, when it became clear that 2020 was on track to break the previous record for big weather disasters, fueled in part by climate change. From the derecho that battered the Midwest with hurricane-force winds to unprecedented wildfires that scorched more than 700,000 acres in Colorado and gave California its worst fire season in history, weather and climate events like these represented only a few line items in the latest tally of the nation’s billion-dollar disasters.
AJ Carrillo farms 18 acres outside of Hotchkiss, Colo., in the high desert of the Western Slope about an hour southeast of Grand Junction. When he irrigates his peach orchard, water gushes from big white plastic pipes at the top of the plot and takes half a day to trickle down to the other end of his five-acre orchard. Carrillo is planning to convert his Deer Tree Farm from flood irrigation, which is commonly used in Western Colorado, to a new and much more efficient style of irrigation – microsprinklers.
