The Colorado River Starts as Snow, and the Way We Understand It Is Changing

/in , /by /KUNCby Alex Hager

High in the Rocky Mountains, under thin air and bluebird skies, the Colorado River basin is slowly filling its savings account. Craggy peaks become smooth walls of white and piles of snow climb conifer trunks, covering even the deepest, darkest corners of the woods with a glimmering blanket.

The snow that accumulates in the mountains of Colorado and Wyoming will eventually become water in the Colorado River. Some of it will flow as far south as Mexico, running through kitchen faucets in cities and suburbs along the way, or watering crops that keep America fed through the winter.

Opinion: Why We Turned the L.A. River Into a Freeway (for Water)

/in , /by /Los Angeles Timesby Patt Morrison

If the Los Angeles River had its own IMDb listing — and why shouldn’t it? It’s appeared in all kinds of movies — its career arc would look something like this:

  • Leading man for tens of thousands of years, star and creator of the epic story of Los Angeles’ ecosystem and living things.
  • Demoted to a supporting role around 1913, when L.A.’s new producers and directors began importing younger, more reliable water.

Slo County Had Driest January and February in More Than 150 Years — Is This the ‘New Normal’?

/in , /by /The Tribuneby John Lindsey Mentioned: https://www.sanluisobispo.com/news/weather/weather-watch/article258890608.html

After reviewing 153 years of rainfall records from Cal Poly’s Irrigation Training & Research Center, there has never been a back-to-back dry January followed by a parched February in San Luis Obispo County. Over the many decades of rain data, if you saw a primarily dry January, it would be followed by a wet February and vice versa during the peak of our rainy season (July 1 through June 30).

Satellite Images Show Just How Quickly Sierra’s Snowpack Is Retreating

The storms that frosted the Sierra Nevada with a healthy layer of snow in December soon gave way to dry weather, and the snowpack is showing it.

Satellite images from NASA show a big difference even between January and February. Images from Jan. 9 showed a blanket of snow over the Sierra Nevada and their foothills, with clouds overshadowing parts of the Bay Area and Central Valley.

California Agriculture Takes $1.2-Billion Hit During Drought, Losing 8,700 Farm Jobs, Researchers Find

/in , , /by /Los Angeles Timesby Ian James

Severe drought last year caused the California agriculture industry to shrink by an estimated 8,745 jobs and shoulder $1.2 billion in direct costs as water cutbacks forced growers to fallow farmland and pump more groundwater from wells, according to new research.

In a report prepared for the California Department of Food and Agriculture, researchers calculated that reduced water deliveries resulted in 395,000 acres of cropland left dry and unplanted — an area larger than Los Angeles. In estimating the costs, they factored in losses in crop revenue and higher costs for pumping more groundwater.

Explainer: UN ‘House on Fire’ Climate Report Key to Action

/in , , /by /AP Newsby Seth Borenstein and Frank Jordans

A new science report from the United Nations spells out in excruciating detail the pain of climate change to people and the planet with the idea — the hope really — that if leaders pay attention, some of the worst can be avoided or lessened.

One scientist calls it the “Your House is On Fire” report.

While these reports often can come across as depressing, to scientists and world leaders, the idea isn’t to lower people’s spirits.

A new era of groundwater management in California continues to take shape as local agencies develop and implement plans that identify how they intend to achieve groundwater sustainability goals over the next 20 years.

“The Sustainable Groundwater Management Act, if you haven’t heard about it, it’s knocking on your door and will soon be pretty much a part of your life if you’re trying to farm,” said Cordie Qualle, professional engineer and faculty fellow at California State University, Fresno.

Arizona Governor Outlines Plan to Boost Water Supplies

/in , /by /San Francisco Chronicleby Bob Christie

Arizona Gov. Doug Ducey and a top leader in the state Legislature on Friday filled in a key part of a developing plan to boost the desert state’s increasingly strained water supply.

They plan to create a state agency to acquire new supplies and develop and fund projects, with deep pockets and the authority to go out and find sources that can secure the state’s water future. One potential project is a multibillion-dollar desalination plant in Mexico, but many others are also being eyed along with efforts to conserve existing supplies.

Undamming the Klamath May Be a Reality This Year

/in , /by /Times Standardby Sonia Waraich

Twenty years ago, undamming the Klamath River seemed like an impossibility. Against all odds, the project is entering its home stretch and dam removal may begin as early as this year.

On Friday, the Federal Energy Regulatory Commission released a draft environmental impact statement detailing how removing four hydroelectric dams on the Klamath River would have permanent and significant benefits for the environment and the public. One of the biggest benefits would be the restoration of water quality and temperatures, which are essential for the survival of fish species in the river that local tribes and fishermen rely upon.

Climate scientists working on the latest international assessment of rising threats to society say it’s imperative that communities adapt now.

Their warning touches on several fields that Arizona and its neighbors in the Southwest are now attempting to tackle, from drought mitigation and wildfire management to the dangers of urban heat.
