Lawmakers Angle for a Seat at the Table in Colorado River Drought Negotiations

/in , , /by /Casper Star-Tribuneby Nick Reynolds

CHEYENNE – For nearly a century, the Colorado River Compact has practically been seen as scripture for states from Wyoming all the way down to the Mexican border.

The compact – written in the years populations in the American Southwest first began to explode – has been the code by which life along the Colorado River Basin has been granted, a strict allocation of the snowmelt from the highest peaks of the Rocky Mountains to the Arizona desert and the parched reaches of the expansive fields of Southern California.

California Scientists Study Climate Change at Bottom of the Ocean

/in , , /by /KPBSby Erik Anderson

California researchers have found that oxygen levels and water temperatures play a key role in the health of deep-sea fish populations. San Diego and Monterey Bay scientists studied fish on the floor of the Gulf of California.

“This is an example of some of the video that we are analyzing for this research,” said Natalya Gallo, a post-doctoral researcher at the Scripps Institution of Oceanography.

She pointed to footage taken along the seafloor on the Gulf of California near the Mexican coast. The pictures come from a remotely controlled submarine. Researchers use the underwater tool to gauge the impact of a warming ocean on fish.

Environmental Disaster or a Key to Clean Energy Future? A New Twist on Hydropower

/in , , /by /Los Angeles Timesby Sammy Roth Mentioned: San Diego County Water Authority

Steve Lowe gazed into a gaping pit in the heart of the California desert, careful not to let the blistering wind send him toppling over the edge.

The pit was a bustling iron mine once, churning out ore that was shipped by rail to a nearby Kaiser Steel plant. When steel manufacturing declined, Los Angeles County tried to turn the abandoned mine into a massive landfill. Conservationists hope the area will someday become part of Joshua Tree National Park, which surrounds it on three sides.

Lowe has a radically different vision.

With backing from NextEra Energy — the world’s largest operator of solar and wind farms — he’s working to fill two mining pits with billions of gallons of water, creating a gigantic “pumped storage” plant that he says would help California get more of its power from renewable sources, and less from fossil fuels.

Utah House Reaffirms Intent to Develop Colorado River Water

/in , , /by /Deseret Newsby Amy Joi O'Donoghue

Utah’s booming population growth and rapid economic development means the need for more water, a higher level of conservation and wise development of water supplies, which are not infinite.

With that in the backdrop, the Utah House of Representatives on Tuesday passed HCR22, which makes clear to neighboring states and policymakers that Utah will someday develop its unused portion of the Colorado River.

The Colorado River, termed the hardest working river in the West, serves 40 million people in the Southwest, including a large population in Utah through a diversion system.

California May Need a ‘Miracle March’ to Prevent an Early and Dangerous Wildfire Season

/in , , /by /AccuWeatherby John Roach

A brush fire that grew to 175 acres in Norco, California, on Tuesday was perhaps a preview of what could be an early and dangerous wildfire season in a state that just had its driest February on record. It was the eighth fire incident in 2020, according to the California Department of Forestry and Fire Protection (CAL FIRE). That already equals the number of fire incidents before April 1 in the last four years combined.

Why Does the Weather Stall? New Theories Explain Enigmatic ‘Blocks’ in the Jet Stream

/in , , /by /Science Magazineby Paul Voosen

It was the summer of 2003 in Europe, and, for a while, it seemed as if Earth’s weather system had broken down. For weeks a huge mass of air stalled over the continent, slowly subsiding and suppressing cloud formation, leaving day after day of brilliantly clear skies. The mercury rose, and a record-breaking heat wave gripped countries including France and Germany, causing 70,000 deaths. Then, as abruptly as it set in, the persistent atmospheric block eased, and high winds brought relief.

Few weather phenomena are as widely experienced—but poorly understood—as an atmospheric block. When a block arises, typically at the western edge of a continent, the jet stream splits, trapping a blob of seemingly static air thousands of kilometers across. Such blocks can last for weeks, and drive heat waves, drought, and winter cold snaps.

San Francisco Could See Its First Rainfall Since January as a Potentially Wetter California Weather Pattern Takes Shape

/in , , /by /The Weather Channelby Linda Lam

Much needed rain will finally return to California and will likely end a month-plus dry streak in San Francisco and Sacramento. Dry conditions have prevailed across most of California since late January due to the upper-level pattern.  A strong area of high pressure aloft near California has pushed the jet stream and storm track northward into the Pacific Northwest.

The persistence of this pattern has resulted in drought conditions during the wet season. Nearly 70% of the Golden State is abnormally dry, and about a third of the state is in moderate drought, according to the latest report from the U.S. Drought Monitor.

Nevada Supreme Court Hears Arguments About the State’s Role in Protecting Water for the ‘Public Trust’

/in , , /by /The Nevada Independentby Daniel Rothberg

The Nevada Supreme Court heard arguments Tuesday in a case weighing how state regulators should consider “public trust” values — the environment or recreation — when the sustainability of lakes or rivers could be harmed by how the state has allocated water rights.

The questions before the court stem from ongoing federal litigation over the use of water in the Walker River. But the case has received significant attention because it could provide an opportunity for the state’s top court to bolster legal protections for the environment. At the same time, agricultural groups, businesses and municipal water users fear a broad ruling could upend their existing water rights.

Projects Create Wetlands, Improve Water Quality in San Diego Region

/in , , /by /Water News Networkby Ed Joyce Quoted: San Diego County Water Authority

Since 2005, the San Diego Integrated Regional Water Management Program has supported and funded water conservation, water quality and resource projects throughout San Diego County.

Program partners, including staff of the San Diego County Water Authority and its 24 member agencies, the California Department of Water Resources, and regional water industry leaders, met at the Water Conservation Garden at Cuyamaca College Monday to celebrate 15 years of achievements.

The program facilitates collaboration on water resources planning and projects in the region by water retailers, wastewater agencies, stormwater and flood managers, watershed groups, the business community, tribes, agriculture, and nonprofit stakeholders.

CWA Approves Shutdown Schedule for Pipeline 5 Work at Moosa Creek

/in , , /by /Village News by Joe Naiman Quoted: San Diego County Water Authority

In 2019, the San Diego County Water Authority repaired a leak to a pipeline in Moosa Canyon. That repair was followed by an assessment of the other two SDCWA pipelines in the area, and one of those was found to be at risk so the CWA will be making repairs to that pipeline.

A CWA board vote, Feb. 27, authorized CWA general manager Sandra Kerl to take the necessary contracting and other actions for the repairs on Pipeline 5 in Moosa Creek. The current schedule includes shutdowns March 30 through April 5 for the installation of isolation bulkheads and May 18 to May 24 for the removal of the bulkheads as well as carbon fiber lining work expected April 6 through May 15.

May 24 is the Sunday of Memorial Day weekend, and the actual shutdown schedule will likely be revised as the repair work progresses.
