Although wetlands cover less than 4% of the Earth’s surface, 40% of all animal species live or reproduce in them. One-third of all organic matter on our planet is stored in places like the gigantic Pantanal wetland in western Brazil, the Sudd floodplain in southern Sudan or the Wasjugan Marsh in western Siberia.
The California Department of Water Resources has secured $308 million in funding to pay for reconstruction and repair work that has been done on the Oroville Dam’s spillways.
The funds, released by FEMA, are in addition to the $260 million that the agency provided for repairs on the lower portion of the dam’s main spillway.
Dry conditions are the worst they’ve been in almost 20 years across the Colorado River watershed, which acts as the drinking and irrigation water supply for 40 million people in the American Southwest.
As the latest round of federal forecasts for the river’s flow shows, it’s plausible, maybe even likely, that the situation could get much worse this year.
Understanding and explaining the depth of the dryness is up to climate scientists throughout the basin. We called several of them and asked for discrete numbers that capture the current state of the Colorado River basin.
Comedian Ron White once joked that we should have two levels of national security warnings: Find a helmet and put on a helmet. If such a system were in place for controversies, Arizona’s water community would now be in the “put on a helmet” stage.
This updates a post from December on the likelihood of California entering a second dry year. Normally, a second dry year brings drought operations for California’s overall water system operations.
Today, it is even likelier that California is entering a multi-year drought.
Precipitation conditions have improved somewhat with a nice atmospheric river this last week, but remain 51% of average for this time of year for the Sacramento Valley. (San Joaquin and Tulare basins are 61% and 47% of historical seasonal average precipitation so far.) Snowpack has improved somewhat with very recent storms, but is about as scarce as the precipitation.
Water suppliers along the drought-stricken Colorado River hope to tackle another tricky issue after the U.S. Bureau of Reclamation installs a new leader: salty water.
The river provides water for 40 million people from Colorado to California, and helps irrigate 5.5 million acres of farm and ranchland in the U.S. But all that water also comes with 9 million tons of salt that flow through the system as it heads to Mexico, both due to natural occurrence and runoff, mostly from agriculture. Salt can hurt crop production, corrode drinking water pipes, and cause other damage.
California’s increasingly volatile warming climate is making droughts more intense, and complicating water management. A just-launched commodity futures market for the state’s water provides a new tool for farmers, municipalities and other interested parties to ensure against water price shocks arising from drought-fueled shortages.
Taking a Wall Street approach to an essential natural resource has prompted both fear and hype. Will California experience a new Gold Rush in water? Will speculation boost the cost of water? Perhaps both the fear and the hype are unwarranted.
If there were any doubts that the climate is changing in the Colorado River Basin, 2020 went a long way toward dispelling them, thanks to yet another year of extreme weather.
Unprecedented wildfires, deadly heat waves, withering drought—the many indicators of the climate mayhem that scientists have been warning about for years—ravaged the landscape, claiming dozens of lives and causing billions of dollars in damage.
Colorado endured an unprecedented wildfire season. And so did California, in some cases burning where the wounds were still fresh from the epic fires of 2018. Utah experienced its driest year ever, and persistent high temperatures killed more people in Arizona than ever before. Monsoon rains that typically bring relief throughout the region were a no-show for the second summer in a row and now are being called the “non-soon.”
Mayors and county supervisors in towns along the Colorado River were already upset five months ago when the state water agency endorsed an investment company’s plan to take water from farmland near the river and sell it to a growing Phoenix suburb.
Now, they’re incensed that the agency, which initially suggested holding back a large portion of the water, changed its stance and will let the company sell most of the water to the town of Queen Creek.
Since the early 1920s, the Long Valley plains east of Yosemite have inspired comparison to a rustic Western paradise — an idyllic frontier where sparkling creeks meander through lush pastures, waters teem with feisty trout and sage grouse make ostentatious displays of romance.
