Hydropower Levels Under Careful Watch as Drought Ravages the West

/in , , /by /Powerby Sonal Patel

Intensifying drought conditions in California and historically low water levels at the Oroville Dam on Aug. 5 forced the state’s Department of Water Resources to shut down the 644-MW Edward Hyatt Power Plant—the fourth-largest energy producer of all California’s hydroelectric facilities.

While the current drought is affecting 95% of the West, it is bearing down severely in California and in the Colorado River Basin. Multiple reservoirs monitored by the U.S. Bureau of Reclamation are “substantially” affected. The federal agency reported on Aug. 8 that at least six of its 44 major reclamation reservoirs—including Hoover Dam and Glen Canyon Dam—have now fallen to their lowest storage values in the last 30 years.

Roseville to Take 1.2 Billion Gallons From Wells to Supply Residents With Water

/in , , /by /Fox40by Connor Malone, Bridgette Bjorlo

The city of Roseville plans to take 1.2 billion gallons from its wells to supply about 53,000 households with running water this summer.

State reservoirs have receded to their lowest point in years. To prepare for dry seasons, Roseville has invested in new technology to boost its groundwater supply by ingesting water from previous snowmelt and rainy seasons into underground wells so when water is most needed, the city isn’t entirely reliant on Folsom Lake.

As the Climate Warms, Electricity Demand Shows a Regional Shift

/in , /by /pv magazineby Ryan Kennedy

Even though American spent more time at home in 2020 during the Covid-19 pandemic lockdown, retail residential sales of electricity per capita rose by only 1% per person, year-on-year from 2019 to 2020, said the Energy Department’s Energy Information Administration. The agency said that warmer weather in 2020, especially a particularly mild winter, increased electricity usage from air conditioning, but cut U.S. electricity usage for space heating during colder months.

EIA reported that from 1960 to 2010, per capita U.S. electricity use posted a 3% average annual increase. That trend slowed over the past decade due to warmer weather and energy efficiency upgrades. Since 2010, per capita residential electricity use has fallen 5% in the U.S.. That means 2020 represented an uptick in demand relative to the broader trend.

California Water District Pays Millions Over ‘Unauthorized Diversion’ From Federal Canals

/in , /by /The Sacramento Beeby Dale Kasler

An obscure farm-irrigation agency in the San Joaquin Valley, the Panoche Water District has been struggling with a monumental scandal the past three years, with top officials under criminal indictment for embezzling public funds and illegally dumping toxic waste.

It turns out the district has also been allegedly taking water from the federal government.

Earlier this year Panoche agreed to pay the U.S. Bureau of Reclamation nearly $7.5 million to compensate for “unauthorized diversion of water” from two federal canals, according to a settlement agreement obtained by The Bee.

‘Code Red’: UN Scientists Warn of Worsening Global Warming

/in , , /by /AP Newsby Seth Borenstein

Earth is getting so hot that temperatures in about a decade will probably blow past a level of warming that world leaders have sought to prevent, according to a report released Monday that the United Nations called a “code red for humanity.”

“It’s just guaranteed that it’s going to get worse,” said report co-author Linda Mearns, a senior climate scientist at the U.S. National Center for Atmospheric Research. “Nowhere to run, nowhere to hide.”

Historic Drought in U.S. West Will Persist Through October

The historic drought stretching across California and the U.S. West will likely last through October, with only minor improvements expected in parts of Arizona and New Mexico.

Drought now covers almost 95% of 11 western states, including all of California, Nevada, Arizona, Utah, Oregon and Idaho, according to the U.S. Drought Monitor. Above-normal temperatures and a dearth of rainfall is expected from August to October, according to the National Oceanic and Atmospheric Administration’s monthly report.

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.
