As drought conditions intensify across Colorado, at least 14 cities in the Denver metro area say they will join forces to warn residents of looming water shortages and the need to cut back use this spring. Denver Water’s Jason Finehout said a metro drought coordination effort would help ensure a consistent message on reducing water use in what is shaping up to be another alarmingly dry year.
Recent storms have boosted California’s vital Sierra Nevada snowpack but not enough to fully compensate for a dry start to winter and residents should use water wisely, a state official said Wednesday after the season’s latest measurements.
Flooding rains and record snow in California last week marked another extreme swing of the state’s climate pendulum. The widespread downpours triggered mudslides that damaged homes and roads near some of the huge fire scars from last summer, and also brought some of the water the state will need to end a months-long hot and dry streak and douse a record-setting wildfire season that extended into January.
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.
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.
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.
Californians have recently endured increasingly aggressive wildfires, rolling power outages, and smoke-filled air for days. Unless the state government changes course, we can add water shortages to this list.
According to the U.S. Geological Survey, California has already suffered three droughts during this century – 2001-2002, 2007-2009, and 2012-2016. To address this reality, the state has enacted legislation to require urban water agencies, under penalty of $1,000 fines per day, to increasingly reduce average water use by residents and businesses, without requiring any significant steps to increase water capture and storage during wet years.
San Diegans got a taste of winter weather Saturday.
“We were actually excited when we saw the rain,” said Forest Padilla, a San Diego resident.
The cold showers lasted throughout most of the day.
“It’s nice to have the rain every once in a while,” said Travis Robertson-Howell, a San Diego resident.
But it may be even nicer to have it a little more often. The latest drought map from the National Integrated Drought Information System showed much of the San Diego region is experiencing abnormally dry conditions.
Luckily it doesn’t appear to show drought in the area. The rest of the state isn’t so lucky. According to the map, drought exists in some way in approximately 95 percent of the state. The state was drought-free at this time last year.
“At this point in the winter it is still fairly early,” said Mike Lee, public affairs manager with the San Diego County Water Authority.
Lee says it’s too soon to raise concerns.
“Just a few storms can radically improve and change the water supply conditions in the snowpack in the mountains,” said Lee. “That can happen in February, sometimes in March, and even April.”
And even if we don’t get all the rain we need, he says the county has a back-up plan.
“Every five years we go through a rigorous planning process at the county water authority and with all of our member agencies across the region to ensure that even if we were to have three, four dry years in a row that we would still have enough safe reliable water to meet our region’s needs,” said Lee.
So for now, Lee says San Diegans can enjoy the wet weather as he expects more is to come.
