California is bone-dry after a heat-wave hit the state, with water levels dipping to all-time lows.


Experts say climate change is responsible for what may become the worst drought the US has seen in 1,200 years.


In the meantime, the West and South West continues to sizzle - and summer has yet to hit its peak.


Residents on the West Coast are in for a miserable, sizzling summer filled with prolonged drought and record-breaking temperatures, say experts.

A scientist the Guardian spoke to even warned that the US could experience one of the worst droughts in its modern history.

"This current drought is potentially on track to become the worst that we've seen in at least 1,200 years. And the reason is linked directly to human-caused climate change," Kathleen Johnson, associate professor of Earth system science at the University of California in Irvine, told the Guardian.

The projection came just as California's rivers and reservoirs dried up and the state recorded historically low water levels.

In particular, if water levels in Lake Oroville, California's second-largest reservoir, continue to dwindle, it could have devastating impacts on the state's power supply. This is because the lake generates energy by flowing through the Edward Hyatt Power Plant. Low water levels may force this power plant to close, leaving around 800,000 homes without energy when wildfire season swings around, per CNN.

The heatwave hitting California prompted Gov. Gavin Newsom to declare a statewide emergency last week. Newsom called on the state's residents to conserve energy, saying that the heat "has and will continue to put significant demand and strain on California's energy grid."

Energy troubles amid the heatwave are also hitting Texas. The Electric Reliability Council of Texas said many power plants in the state went offline last week, just months after a major outage left Texans without heat during in the middle of winter.

The Washington Post reported on June 18 that more than 40 million Americans saw triple-digit temperatures where they live in the prior week. Temperature records were also broken in Salt Lake City last Tuesday when the weather services measured a high of 107 degrees, smashing the area's 147-year record for temperatures in June.

What makes the US's weather troubles worse is that summer hasn't even peaked.

According to the National Centers for Environmental Information's archive of temperatures across the US from 1981 to 2010, the amount of sun's rays reaching Earth tends to peak on the summer solstice on June 21. However, the US tends to see warm temperatures increasing into July. The National Oceanic and Atmospheric Administration said the summer of 2020 was one of the hottest ever seen in the US, with August, in particular, being especially "dry and destructive."

As summer 2021 rolls in, the potential for wildfires in many areas of western North America increases. Drought in the region has been on the rise for months, and at this point, more than a third of the area extending from the southwest United States into southern Canada is in a severe to extreme situation.

With tinder-like conditions already present in many drought affected areas, experts warn that when intense heat waves and strong dry winds join this vulnerable scenario, wildfires will be very easy to spark and could quickly become extremely dangerous.

Wildfire experts Daniel Swain and Mike Flannigan weigh in on what this wildfire season could shape up to be, and the main ingredients that could potentially make this a season to remember. Watch the video above to hear what they have to say.

West's drought has no end in sight: 'If we do nothing, it’s going to be really bad'


Joel Shannon and Christal Hayes, USA TODAY
Sun, June 20, 2021

Spring rainstorms weren’t enough to fill Utah’s reservoirs or rejuvenate the soil, so Gov. Spencer J. Cox took his plea to Twitter: Fix your leaky faucets, stop taking long showers, get rid of the lawn – and pray for rain.

The crisis isn’t unique to Utah. About 40% of the country is experiencing drought conditions, according to U.S. Drought Monitor. Drought has been a consistent problem in the Southwest for about two decades, and it’s increasingly creating an existential question: Does the West have enough water to go around?

Huge reservoirs are drying up as drought threatens farms and fuels wildfires. Cox, a Republican, warned the drought puts crops, livestock, wildlife, the state’s food supply and “really, our way of life” at risk.


It's all happening at a pace that is surprising and alarming experts. Some worry that without major water conservation, the West could be on track for unprecedented water shortages.

States and local governments are ramping up rules aimed at cutting back water usage, and most of the initial burden is expected to hit farmers, who are responsible for the vast amount of water use. But individuals are also seeing water restrictions affect them – especially if they have a lawn to water.

Even so, conservation may not be enough to fix the problem, Cox feared. “We need some divine intervention.”

Scientists and advocates suggest another solution: The West needs to drastically cut its water usage, and that means more than taking shorter showers.

Rain alone unlikely to fix the drought problem

Droughts can be short-term, but the one facing the West probably isn’t. The problem appears to be too big, the trend too strong to be reversed by drenching rains or a few above average years of precipitation.

“I don’t see a going back to a pre-drought time any time soon,” Veva Deheza, executive director of the National Integrated Drought Information System, told USA TODAY.

A spring 2020 study warned that the West is exiting an unusually wet time in its history and heading straight into an unusually dry time that could last years, decades or centuries.

Scientists see that trend playing out year after year.

“The anticipation is always that, eventually, rain will come. And so we’re stretching out the water that we do have,” said Nancy Selover, who recently retired as Arizona’s state climatologist.

She compared the water supply issues in the West with that of survivors on a desert island. “You have to say: How long do you think it’ll be until somebody rescues us? How much does everyone get when you simply don’t know when the rain will come?”

Typically, states use massive reservoirs to store extra water from years with above-average precipitation so it can be used during drier times. It’s a complex system involving more than just rain water: melted snow from mountainous regions is among one of the biggest concerns.

But these are not normal times.

Scientists describe the past two decades as a drought worsened by climate change, population growth and increased agricultural needs, and the say the Colorado River Basin is undergoing “aridification” that will complicate water management for generations to come. That’s especially troubling for the seven states that rely on the Colorado River for water: Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming.

Drought is a concern across the country, Deheza said. They're occasional in the East and sometimes extreme in the Midwest. But in the West, particularly in the Southwest, they've recently been nearly pervasive.

Droughts in wetter climates can put a short-term strain on water systems that can spiral into a crisis. A 2016 drought in Georgia led to concerns about taps running dry.

But in the already dry Southwest, the slow-moving crisis is just as severe but will take much longer to turn around – especially amid concerns the climate is becoming more desert-like.

“It’s getting harder and harder to recover from these low … years,” John Berggren, a water policy analyst with Western Resource Advocates, told USA TODAY. Berggren said reservoir levels are dropping without any good years to help replenish them.

Drought has ripple effects, Berggren said. Just one of them: Dry soil can suck up moisture before it reaches reservoirs, making it hard to fill them back up, even during an unusually wet year.

And Deheza said warming temperatures cause more water to evaporate, also complicating efforts to build up reserves.

It takes intricate planning to ensure dry years won’t damage most people’s day-to-day lives. But with growing uncertainty about the changing climate of the Southwest, it’s getting harder to make those plans, Deheza said.

Drought concerns growing at an alarming pace

The largest reservoir in the country made headlines in early June when it dipped to a record low, a rapid decline that outpaced projections from just a few months ago.

Lake Mead then stood at just 36% of full capacity, and the spiral shows no sign of letting up. That's a troubling statistic for the Hoover Dam, where low water levels have reduced energy capacity by 25%. Typically, the dam powers enough electricity to serve more than 1 million people a year across Nevada, Arizona and California.

A similar situation is playing out in Northern California’s Lake Oroville, where one hydroelectric power plant will probably have to shut down for the first time ever because of the abnormally low water levels.

“Things are starting to plummet pretty drastically,” Berggren said.

Doing nothing to reduce water usage could lead to an unimaginable future for the West, Berggren said: “If we do nothing, it’s going to be really bad.”

A high-water mark or "bathtub ring" is visible on the shoreline of Lake Mead at Hoover Dam.

He described a world where rivers run dry, dust overruns the landscape, some taps stop flowing and millions of people flee in search of water.

But that hypothetical isn’t imminent, and much can be done to prevent it, Berggren said.

Many experts note that while conditions are worsening and only exacerbated by climate change, the West has always been dry and has experienced prolonged periods of droughts.

Jay Lund, a professor at the University of California, Davis who heads its Center for Watershed Sciences, described prolonged periods of precipitation and dry periods over centuries, sometimes lasting decades.

“We’ve always had a lot of trouble with droughts. Always,” Lund said. “The difference here is now the temperatures are higher. Now we have more people. Now we have more agriculture. Now we need more water and have an increased demand.”

And just a small adjustment, such as temperatures becoming just a few degrees warmer, can start a ripple effect on everything from water levels, food prices, water consumption and wildfires.
Water conservation hits farms, lawns first

Water conservation won’t bring back the rain, but experts say it’s a needed step to help prevent widespread water shortages.

Contingency plans for how to divide up water among states as shortages hit have already been made, and cutbacks are expected in the coming year.

Agriculture – which uses about 90% of ground and surface water in some Western states, according to the U.S. Department of Agriculture – is likely to be the first to endure shortages.

There are short and long-term changes farmers can make, all of them challenging. Upcoming water shortages may be temporary, but farmers may have to rethink their approach to low-value crops like hay and alfalfa – especially in areas where a lot of water is needed to grow them. Some farmers might even elect to leave the region, something that also could have ramifications on the interconnected agriculture community and prices in grocery stores.

Selover noted that more farmers are fallowing their fields, letting land rest and go unplanted for a period of time, when water is in short supply. But for some, such as those growing pecans or walnuts, one year without watering an orchard means trees die and won’t be able to produce again for up to a decade.

“If you have one year that you don't provide water to the trees, they die, and next year's water isn't going to bring them back. So now you've lost everything,” she said. “A lot of those trees take five, seven, 10 years of growing before they produce the first nut.”

The choices aren’t easy.

“They’ll either have to plant different crops that don’t use as much water or they’ll just have to fallow their fields,” Selover said.

Berggren said conservation will require changes in the landscapes that surround homes and cities. In many cases, water-guzzling plants and grasses should be replaced with more drought-tolerant native landscapes that look great and are better suited to the climate.

Cutting back on water is something parts of California are already familiar with, even if puts only a small dent in overall water use. In June in Redding, California, City Manager Barry Tippin said the city may again use "water police" to enforce conservation rules if the drought worsens.

In the past, the workers left door hangers that spelled out water use cutback rules and explained strategies to use less water.

People who watered lawns on days they shouldn't have or otherwise broke conservation rules could expect a visit from the "water police."

Meanwhile, Nevada has moved to outlaw “non-functional turf” in the Las Vegas area – decorative grass that guzzles water and isn’t used by anyone.

In Iowa, Des Moines Water Works has asked central Iowa residents to cut lawn watering by 25%.

But experts know conservation has its limits: “Let’s face it, if these conditions continue to persist and get worse, conservation practices only get you so far,” Deheza said.

Drought-plagued regions may need to make major structural changes in how communities and industry use water. She said history tells us both do a “fantastic job of adapting” when needed. And the Southwest has plenty to learn from communities in Africa and the Middle East that have long lived in deserts.

But it's increasingly clear simply waiting for the water to come back won't end the crisis.

“You can never fix this problem,” Lund said. “There is no solution. It’s like fixing the problem with hurricanes on the East Coast. You don’t. You live with it and learn how to manage it.”
