A research study just published in Nature Reviews Earth & Environment provides new information about how much the planet has warmed and what warming we may expect in the coming decades. This study is important because it motivates us to take actions to mitigate and respond to climate change. It shows what will happen if we don’t take action to slow global warming.
Hydropower production on the Upper Colorado River system for water year 2022, which ended on Sept. 30, was down about 20% compared with the previous year and about 30% compared with the yearly average since 2000, according to a Bureau of Reclamation official who oversees hydroelectric generation.
“The outlook is likely for pretty low generation years,” said Nick Williams, the Bureau’s Upper Colorado River Basin power manager.
A much-anticipated water storage project in northern California received a major financial commitment from the federal government Monday.
According to the Bureau of Reclamation, the Biden Administration has committed $30 million from the Bipartisan Infrastructure Law to the Sites Reservoir project.
President Richard Nixon vetoed the Clean Water Act in 1972. But Congress overrode him on a bipartisan vote, and the landmark law to reverse the toxic degradation of U.S. rivers, lakes and streams took effect half a century ago today.
The law was inspired in part by the notorious 1969 Cuyahoga River fire in Ohio, in which the river itself, laden with oil and other industrial pollutants, went up in flames.
In the past 25 years, California’s Salton Sea has grown more polluted and hazardous as it has lost one-third of its water. Shrinkage of similar lakes elsewhere mainly stems from warming trends and water diversion.
But a new paper in the journal Water Resources Research suggests that might not be the case with California’s most polluted inland lake.
The San Diego County Water Authority wants to keep the lights on, even when the Sun goes down. It plans to use San Vicente Reservoir to store solar power energy in so-called water batteries to maximize the city’s renewable energy potential, NPR reports.
Cities across California have an abundance of sunny days, which is perfect for providing renewable energy… as long as the Sun is up. The proposed project could store 4,000 megawatt-hours of energy per day, which could power 135,000 homes after the Sun goes down. To make this possible, the San Diego Water Authority would create a smaller upper reservoir just above the existing San Vicente Reservoir. These would be connected by a tunnel system and an underground powerhouse.
Water supplies are dipping and the outlook for the coming rainy season is iffy at best. That’s the main takeaways from Thursday’s online drought town hall held by Sonoma County.
The San Diego County Water Authority has an unusual plan to use the city’s scenic San Vicente Reservoir to store solar power so it’s available after sunset. The project, and others like it, could help unlock America’s clean energy future.
Two of the biggest reservoirs in the Colorado River Basin, Lake Mead and Lake Powell, have lost 50% of capacity within the past five years.
And, it’s only getting worse.
Now, the Interior Department is proposing more solutions to help the dwindling river.
California regulators this week approved a $140 million desalination plant that could convert up to 5 million gallons of seawater each day into drinking water, as the state grapples with a persistent megadrought and plummeting water supplies.
The state’s Coastal Commission on Thursday voted 11-0 to approve the Doheny Ocean Desalination Project in Orange County in Southern California. The plant could be functioning within the next five years and supply water for thousands of people in the South Coast Water District.
