Water Cutbacks Coming to Arizona

/in , , /by /Arizona Public Mediaby Christopher Conover

The “bathtub ring” at Lake Mead has become a familiar sight. The water level in the lake is the lowest it has been since the Hoover Dam, which created the lake, was built in the 1930s. Those low levels have been decades in the making.

“Back in around 2000, Lake Mead was pretty close to being full, but over the last 20 years-plus now we’ve just not had good hydrologic conditions. It will take years to recover from that, years of good conditions and unfortunately the climate models and projections don’t predict us getting cooler and they don’t predict us, let’s say, getting wetter,” said Dr. Sharon Megdal, University of Arizona professor and former board member for the Central Arizona Project.

California Drought: Santa Clara County Residents Falling Far Short of Water Conservation Target

/in , , /by /The Mercury Newsby Paul Rogers

When it comes to California’s worsening drought, Santa Clara County residents are falling far short in conserving water.

On June 9, the Santa Clara Valley Water District, the county’s main wholesale water provider, declared a drought emergency and asked all 2 million county residents to cut water use by 15% from 2019 levels as local reservoirs dropped alarmingly and state and federal water agencies reduced water deliveries.

But new numbers out Friday show that instead of hitting the 15% target, residents saved 0% in June — essentially using the same amount of water as they did in June 2019.

Study Reveals Effects of Extreme Heat on Tens of Millions of Americans

/in , , /by

The summer of 2020 brought fear of Covid-19, social distancing – and heat-related health problems that affects tens of millions of Americans.

During those months, more than a quarter of the US population suffered from the effects of extreme heat, according to a study released this week. People reported health symptoms like nausea and cramps, as well as a decreased ability to focus, and the effects hit low-income households the hardest.

The study focuses on last summer but given the brutal heatwaves that have hit the US in 2021, especially in western states, it raises the prospect that the impact of extreme heat is highly likely to be worse this year.

Big Battle Looms Over California Water Rights

/in , , /by /CalMattersby Dan Walters

California doesn’t have enough water to meet all demands even in wet years, and when drought strikes the competition becomes, to put it mildly, intense.

State and federal officials who must ration the restricted supply are beset with pleas from farmers, municipal water systems and advocates for the environment.

However, water managers must also contend with a bewildering array of water rights, some of which date to the 19th century, as well as long-standing contractual obligations and laws, both statutes and judicial decrees, on maintaining flows for spawning salmon and other wildlife.

Drought Hits South American River, Threatening Vast Ecosystem

The Paraná River, one of the main commercial waterways in South America, has reached its lowest level in nearly 80 years due to a prolonged drought in Brazil that scientists attribute to climate change.

At peril is a vast ecosystem that includes potable water for 40 million people, the livelihood of fishing communities and farmers, and the navigability of a major grain export hub.

The National Water Institute of Argentina has defined the low water level of the Paraná River, which goes through Brazil, Paraguay, and Argentina, as “the worst since 1944.”

California Hydroelectric Plant Shut as Water Level Drops

/in , , /by /AP News

Drought-stricken California on Thursday shut down one of its largest hydroelectric plants because there’s not enough water to power it.

The six-turbine Edward Hyatt Power Plant was taken off-line after the water level in the Oroville Dam reservoir that feeds it sank to an historic low of less than 642 feet (195.7 meters) above mean sea level.

The reservoir in the Sierra Nevada foothills north of Sacramento was less than a quarter full.

Drought Will Force Western U.S. to Rethink Water Use, Experts Say

/in , /by /Newsweekby Troy Albert Schulz, Zenger News

A record hot summer has laid bare a stark new reality for many states on America’s West Coast: Amid rising temperatures and worsening droughts, many will need to systematically rethink the way they manage limited water supplies.

“One of the problems with rising temperatures is how it’s going to affect water management,” said Washington state’s official climatologist, Nicholas Bond. “Simply from an agricultural point of view, generally when it is warmer, the demands of crops for water goes up. At higher temperatures, crops need more to be able to thrive.”

Lake Mendocino Reaches Second-Lowest Level in History

/in , , /by /The Press Democrat (Santa Rosa)by Mary Callahan

Historic drought has reduced Lake Mendocino to its second-lowest level since it was built, leaving reservoir storage in startling condition with months of likely warm, dry weather still ahead.

The lake on Thursday held just more than 24,000 acre feet of water — a result of critically low rainfall totals that, combined, make 2019-21 the driest two years on record, the National Weather Service said.

Storage in the reservoir, completed in 1958 with a flood storage capacity of 122,400 acre feet, has dipped below 25,000 acre feet only three times before and below 24,000 acre feet only once — by half, according to Sonoma Water.

Opinion: California Could Have Water to Avoid Droughts, But Lacks the Political Will

/in , /by /Times of San Diegoby Marie Waldron

Droughts are a fact of life in California and shouldn’t come as a surprise to anyone. Yet somehow we don’t seem capable of preparing for them.

We are now in the second year of severe drought, and much of California’s agriculture, especially in the Central Valley, is facing devastation.

‘Running out of Options’: California Resorts to Water Cutoffs as Drought Worsens

/in , , /by /Los Angeles Timesby Julia Wick

California water regulators took unprecedented action this week, passing an emergency regulation that will bar thousands of Californians from diverting stream and river water as the drought worsens.

The State Water Resources Control Board voted unanimously Tuesday to pass the “emergency curtailment” order for the Sacramento-San Joaquin Delta watershed. The watershed encompasses a wide swath of the state, from the Oregon border in northeastern California down into the Central Valley.
