SANTA MONICA, Calif. – California closed a large hydropower plant on Lake Oroville when the water level fell near the minimum required to generate electricity, state water authorities said.

It is the first time since the power plant opened in 1967 that the state has shut down the Hyatt power plant due to a lack of water.

The blackout could trigger even more blackouts this summer as the state grapples with a historic drought and record-breaking heat waves.

Officials said the record low water level at Lake Oroville, an artificial water reserve in Northern California, was due to the drought aggravated by climate change.

Though California is experiencing constant drought, climate change has fueled high temperatures and arid soils, which significantly reduced water runoff to the reservoirs this spring, resulting in the lowest levels ever recorded at Lake Oroville, officials said Thursday.

“This is just one of many unprecedented impacts we are experiencing in California as a result of our climate-induced drought,” Karla Nemeth, director of the state’s water resources division, said in a statement.

Nemeth said the department anticipated the shutdown and planned a loss of water and network management. Officials have warned that the facility will no longer be able to generate electricity if the water level drops below 640 feet above sea level.

Dry land is visible in a section that is usually underwater on the shores of Lake Oroville, which is the second largest reservoir in California and has a capacity of nearly 35, according to daily reports from the state Department of Water Resources near Oroville, California % hat, 06/16/2021.

Lake Oroville’s water levels are expected to reach 620 feet above sea level by the end of October. Nemeth said the state’s water board was working to “save as much water as possible”.

Although the facility is no longer generating electricity, officials said they will dump some water from the dam into the Feather River to help maintain the river’s temperature requirements.

Governor Gavin Newsom urged California residents in July to reduce household water use by 15% in order to maintain water supplies. Network operators have also urged residents to limit electricity usage to avoid blackouts as forest fires scorched the state, including the Dixie Fire, which has been burning for more than three weeks and decimated the gold rush town of Greenville.

“Falling reservoir levels are another example of why it is so important for all Californians to conserve water,” said Nemeth.

Taiwan Drought: Residents Pray for Rain and Scramble to Save Water

TAICHUNG, Taiwan — Lin Wei-Yi once gave little thought to the water sluicing through her shower nozzle, kitchen faucet and garden hose.

But as Taiwan’s worst drought in more than half a century has deepened in recent weeks, Ms. Lin, 55, has begun keeping buckets by the taps. She adopted a neighbor’s tip to flush the toilet five times with a single bucket of water by opening the tank and directly pouring it in. She stopped washing her car, which became so filthy that her children contort themselves to avoid rubbing against it.

The monthslong drought has nearly drained Taiwan’s major reservoirs, contributed to two severe electricity blackouts and forced officials to restrict the water supply. It has brought dramatic changes to the island’s landscape: The bottoms of several reservoirs and lakes have been warped into cracked, dusty expanses that resemble desert floors. And it has transformed how many of Taiwan’s 23.5 million residents use and think about water.

“We used too much water before,” Ms. Lin said this week in the central city of Taichung. “Now we have to adapt to a new normal.”

No typhoons made landfall in Taiwan last year, the first time since 1964. Tropical cyclones are a prime source of precipitation for the island’s reservoirs. Some scientists say the recent lack of typhoons is part of a decades-long pattern linked to global warming, in which the intensity of storms hitting Taiwan has increased but their annual frequency has decreased.

Ordinary rainfall has also been drastically lower than normal this year, particularly in the central region that includes Taichung, a city of 2.8 million people and the second-largest on the island. The water shortage could begin to ease this weekend if heavy rains arrive on Saturday, as some forecasters predict. But as of Friday, the water levels at two main reservoirs that supply Taichung and other central cities were hovering between 1 percent and 2 percent of normal capacity.

In a few cases, the usual residents of the island’s lakes and reservoirs — fish — were replaced by other species: tourists and social media influencers taking pictures of the visually startling terrain for Instagram posts. In one of the most photogenic locations, Sun Moon Lake, a reservoir in central Taiwan, the receding waterline has revealed tombstones that historians say may date to the Qing dynasty.

“It’s been meltingly hot in Taichung for a while now,” said Huang Ting-Hsiang, 27, a chef who works out of his home and stopped cooking last month for lack of water. “The images of the dangerously low levels at those reservoirs are scary, but there’s nothing we can do.”

To fight the drought, the government has been drawing water from wells and seawater desalination plants, flying planes and burning chemicals to seed clouds above reservoirs, and halting irrigation over an area of farmland nearly the size of New York City.

It has also severely restricted residential water deliveries. In Taichung and other hard-hit cities, the taps have been cut off for two days a week since early April. Some residents have low water pressure even on the other days. Officials have said the curbs will become more severe, starting on Tuesday, if the heavy rainfall that is expected over the weekend does not materialize.

Lo Shang-Lien, a professor at the Graduate Institute of Environmental Engineering at National Taiwan University, said that the current restrictions were necessary in part because people on the island tend to use a lot of water.

In Taichung, the daily rate of domestic consumption per person is 283 liters, or nearly 75 gallons, according to government data from 2019. In Taipei, the capital, it is 332 liters per day. By contrast, average residential water consumption in Europe is about 144 liters per person per day and 310 liters in the United States, according to official estimates.

Professor Lo said that Taiwan’s water usage was relatively high in part because its water prices — some of the lowest in Asia, according to Fitch Ratings — incentivize excess consumption. “Given all the extreme climatic events of recent years, water policies have become something that we need to reconsider and replan,” he said.

Raising those prices would be politically sensitive, though, and a spokesperson for the Water Resources Agency said that the government had no immediate plans to do so.

For now, many people in Taiwan are watching the skies and praying for rain.

In one sign of the public mood, more than 8,000 social media users tuned in to a recent government livestream of an hourlong afternoon thunderstorm at a reservoir in northern Taiwan. A bubble tea shop in the northern city of Taoyuan said that it would stop serving ice with drinks until the water restrictions were lifted. And in Taichung, irrigation officials held a rain-worshiping ceremony at a temple — the first such event there since 1963 and only the fourth since the temple was built, in 1730.

Ms. Lin, who stopped washing her car, cleans dishes in an assembly line of metal pots with dishwater that she arranges from dirtiest to cleanest.

“I still need to wash whatever I need to wash,” she said, “but now every drop needs to be used twice.”

For the first few weeks of the rationing, some people looked for ways to escape life without running water. Ms. Lin went sightseeing in the eastern city of Hualien and visited one of her daughters in Taipei. Others went bathing in hot springs.

Lin Ching-tan, who owns the Kylin Peak Hotspring resort in Taichung, said that he had lowered the admission price by half, to about $5, as a humanitarian gesture. He also started bathing at work before going home in the evenings.

“If you don’t have water to take a shower, it can be torture,” he said.

But as the government restricts movement in an effort to fight Taiwan’s most severe coronavirus outbreak since the start of the pandemic, more of the island’s residents are stuck at home, looking for creative ways to make scarce water supplies last longer. On Facebook and other social media platforms, people have been sharing water-saving tips, including how to flush toilets more efficiently or install a second rooftop water tank.

Mr. Huang, the chef, said that he and his family have a system for storing water in buckets, pots and tanks before their taps run dry every Tuesday and Wednesday. They also try to order takeout so that they won’t have to use water for cooking, he added, although their favorite restaurants and food stalls sometimes close for the same reason.

Ms. Lin’s system includes placing a plastic container under her feet while showering, then flushing the toilet with it.

This week, on her balcony, she poured used kitchen water over some flowers but left others to wilt. “There’s no turning back from extreme weather,” she said. “Developing good habits for saving water is probably just a rehearsal for frequent droughts of the future.”

Taiwan’s Drought Pits Chip Makers In opposition to Farmers

HSINCHU, Taiwan – Chuang Cheng-deng’s humble rice farm is a stone’s throw from the nerve center of Taiwan’s computer chip industry, whose products power much of the world’s iPhones and other devices.

This year, Mr. Chuang pays the prize for the economic importance of his high-tech neighbors. Taiwan has been hit by drought and crawling to save water for homes and factories, and has stopped irrigation on tens of thousands of acres of farmland.

The authorities compensate the producers for the loss of income. However, 55-year-old Chuang fears that the thwarted harvest will lead customers to seek other suppliers, which could mean years of poor revenue.

“The government uses money to shut the farmers’ mouths,” he said, studying his parched brown fields.

Officials call Taiwan’s drought the worst in more than half a century. And it depicts the tremendous challenges associated with hosting the island’s semiconductor industry, which is an increasingly indispensable hub in the global supply chains for smartphones, automobiles, and other cornerstones of modern life.

Chip makers use a lot of water to clean their factories and wafers, the thin silicon disks that form the basis of the chips. And with global semiconductor supplies already being weighed down by soaring demand for electronics, the added uncertainty about Taiwan’s water supply is unlikely to allay concerns about the tech world’s reliance on the island, and particularly on a chip maker, Taiwan Semiconductor Manufacturing Company.

More than 90 percent of the world’s most advanced chip manufacturing capacity is in Taiwan and operated by TSMC, which makes chips for Apple, Intel, and other big names. The company announced last week that it would invest $ 100 billion over the next three years to increase capacity, which is likely to further strengthen its preeminent market presence.

The drought has not affected production so far, according to TSMC. With Taiwan’s rainfall becoming unpredictable despite the growth of the tech industry, the island must make ever greater efforts to maintain the flow of water.

For the past few months the government has flown planes and burned chemicals to sow the clouds over the reservoirs. A seawater desalination plant has been built in Hsinchu to house TSMC’s headquarters, as well as a pipeline connecting the city to the rainier north. It has directed the industry to reduce usage. In some places it has lowered the water pressure and cut the supply for two days a week. Some companies, including TSMC, have been pulling in truckloads of water from other areas.

The most comprehensive measure, however, has been to stop irrigation, which affects 183,000 acres of arable land, roughly one-fifth of Taiwan’s irrigated land.

“TSMC and these semiconductors don’t feel it at all,” said Tian Shou-shi, 63, a rice farmer in Hsinchu. “We farmers just want to be able to earn an honest living.”

In an interview, Taiwan Water Resources Agency’s assistant director Wang Yi-feng defended the government’s policies, saying the dry spell means crops will be poor even with access to irrigation. Redirecting scarce water to farms instead of factories and homes would be “lose-lose,” he said.

When asked about farmers’ water problems, a TSMC spokeswoman, Nina Kao, said it was “very important for every industry and business” to use water efficiently and noted TSMC’s involvement in a project to improve irrigation efficiency .

That Taiwan, one of the rainiest places in developed countries, should not have water is a paradox that borders on tragedy.

Much of the water used by the residents is deposited by the summer typhoons. But the storms also pour soil from Taiwan’s mountainous terrain into its reservoirs. This has gradually reduced the amount of water that reservoirs can hold.

The rains are also very different from year to year. Not a single typhoon landed in the rainy season last year, the first time since 1964.

Taiwan last stopped large-scale irrigation in 2015 and 2004 to save water.

“If the same conditions reappear in two or three years, we can say, ‘Ah, Taiwan has definitely entered an era of great water scarcity,” said You Jiing-yun, professor of civil engineering at National Taiwan University wait and see. “

In 2019, the TSMC facilities in Hsinchu used 63,000 tons of water per day, or more than 10 percent of the supply from two local reservoirs, Baoshan and Baoshan Second Reservoir, according to the company. TSMC recycled more than 86 percent of the water from its manufacturing processes this year, saving 3.6 million tons more than last year by stepping up recycling and taking other new measures. But that amount is still small next to the 63 million tons consumed at the Taiwanese plants in 2019.

Mr. Chuang’s business partner at his Hsinchu farm, Kuo Yu-ling, does not like demonizing the chip industry.

“If Hsinchu Science Park wasn’t as developed as it is today, we wouldn’t be in business,” said Ms. Kuo, 32, referring to the city’s main industrial area. TSMC engineers are important customers for their rice, she said.

But it is also wrong, said Ms. Kuo, to accuse farmers of devouring water while contributing little economically.

“Can’t we account fairly and precisely how much water farms use and how much water industry uses, and not constantly stigmatize agriculture?” She said.

The “biggest problem” behind Taiwan’s water problems is that the government is keeping water tariffs too low, said Wang Hsiao-wen, a professor of hydraulic engineering at National Cheng Kung University. This encourages waste.

Households in Taiwan use around 75 gallons of water per person every day, government figures show. Most Western Europeans use less than that, although Americans use more, according to the World Bank.

Mr. Wang of the Water Resources Agency said, “Adjusting water prices is having a major impact on more vulnerable groups in society. So we are extremely cautious about adjustments. ”Taiwan’s prime minister said last month that the government would consider adding fees to 1,800 water-intensive factories.

Lee Hong-yuan, a professor of hydraulic engineering who previously served as Taiwanese interior minister, also blames a bureaucratic quagmire that makes it difficult to build new wastewater recycling plants and modernize the pipeline network.

“Other small countries are all extremely flexible,” said Lee, “but we have the operating logic of a big country.” He believes this is because Taiwan’s government was established decades ago after the Chinese Civil War with the aim of ruling all of China. It has since lost that ambition, but not the bureaucracy.

Taiwan’s southwest is both an agricultural heartland and an emerging industrial hub. TSMC’s most modern chip facilities are located in the southern city of Tainan.

The nearby Tsengwen Reservoir has shrunk to a swampy stream in some places. Along a scenic strip known as Lovers’ Park, the bottom of the reservoir has become a vast moonscape. According to the government, the water volume is around 11.6 percent of the capacity.

In farming towns near Tainan, many growers said they were content, at least for the time being, to live on the government cent. They clear the weeds from their fallow fields. They drink tea with friends and go on long bike rides.

But they also count on their future. The Taiwanese public appears to have decided that growing rice is less important than semiconductors to both the island and the world. Heaven – or at least greater economic forces – seem to be telling farmers that it is time to find other work.

“Fertilizer is getting more and more expensive. Pesticides are getting more and more expensive, ”said Hsieh Tsai-shan, 74, a rice farmer. “Being a farmer really is the worst.”

Quiet farmland surrounds the village of Jingliao, which became a popular tourist spot after a documentary film about the changing lives of farmers.

There’s only one cow left in town. It spends its days attracting visitors and not plowing fields.

“Here, 70 counts as young,” said Yang Kuei-chuan, 69, a rice farmer.

Both of Mr. Yang’s sons work for industrial companies.

“If Taiwan had no industry and relied on agriculture, we might all have starved to death by now,” said Yang.
