Severe Drought, Worsened by Climate Change, Ravages the American West

/in , , /by /The New York Timesby Henry Fountain

This year, New Mexican officials have a message for farmers who depend on irrigation water from the Rio Grande and other rivers: Unless you absolutely have to plant this year, don’t.

Years of warming temperatures, a failed rainy season last summer and low snowpack this winter have combined to reduce the state’s rivers to a relative trickle. The agency that controls irrigation flows on the Rio Grande forced the issue. To conserve water, it opened its gates a month later than usual.

Severe drought — largely connected to climate change — is ravaging not only New Mexico but the entire Western half of the United States, from the Pacific Coast, across the Great Basin and desert Southwest, and up through the Rockies to the Northern Plains.

In California, wells are drying up, forcing some homeowners to drill new ones that are deeper and costlier. Lake Mead, on the border of Arizona and Nevada, is so drained of Colorado River water that the two states are facing the eventual possibility of cuts in their supply.

Where’s the Water? Drought Threatens California’s Lifeline

/in , , /by /The New York Times by Priya Arora

Even as California moves toward a full reopening from pandemic restrictions next month, many counties are still in danger.

From drought.

Earlier this month, Gov. Gavin Newsom extended emergency drought orders to 41 counties across the state. According to the United States Drought Monitor, 84 percent of the West is now in drought conditions, with 47 percent rated as “severe” or “extreme.” In California, 73 percent of the state falls into those categories. And if the recent Palisades fire in western Los Angeles is any indication, an active wildfire season could already be here.

San Diego County Mitigation Efforts Aid in California Drought Battle

/in , , /by /10 News (KGTV) San Diegoby Zac Self Quoted: San Diego County Water Authority

As the drought deepens throughout California, San Diego County has postured itself to make it through dry spell conditions as a result of planning and mitigation efforts.

After experiencing a severe drought in the early 1990s, San Diego County officials went to work on diversifying its water supply. At the time, the region was hit with 50% supply reductions because it relied almost entirely on a single source. Since then, however, the San Diego County Water Authority has taken a varied approach. According to the authority, the region has added a new transfer of conserved agriculture water from Imperial Valley and completed the All-American and Coachella Canal lining projects to receive conserved water from the Colorado River.

“The Water Authority’s draft 2020 Urban Water Management Plan shows that regional investments in a ‘water portfolio approach’ to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have sufficient water supplies through the 2045 planning horizon – so the region’s residents and economy remain safe even during multiple dry years,” the authority told 10News.

A new study conducted by researchers from The University of New Mexico has found that wildfires—which have been increasing in frequency, severity and extent around the globe—are one of the largest drivers of aquatic impairment in the western United States, threatening our water supply. The research, “Wildfires increasingly impact western U.S. fluvial networks,” was published recently in Nature Communications.

Arizona’s Continuing Population Growth Puts Pressure On Water Supply

Millions of people are betting on Arizona. They’re buying homes, starting businesses, and families. The future of how we use our water resources may dictate the future of their success. “We don’t want to put consumers and businesses at risk when they built and there was a hundred years of water but what happens 80 years from now, is there still 100 years of water left,” said Haley Paul, a regional director for the Audubon Society. That question was addressed four decades earlier with the Groundwater Management act of 1980. The idea was the law would ensure when water was taken out, just as much was put back in, creating what they called a safe yield goal by 2025.

New Report: Drought to Hit Rural Latino Communities Hardest

/in , , /by /CalMattersby Rachel Becker

Rural, low-income Latino communities across California were hardest hit by the last drought and could see drinking water shortages again this year as extreme drought spreads across the state, according to a report released today by non-partisan advisors to California’s lawmakers.

The report from the Legislative Analyst’s Office warns state officials to prepare by ramping up monitoring of wells in vulnerable communities and lining up emergency drinking water supplies to send there.
