Proposed Federal Grant Program Could Bolster Lake Mead Water Levels
Water officials in Las Vegas are backing a federal bill that could help pay for a California project that would leave more water in Lake Mead.

It’s Some of America’s Richest Farmland. But What Is It Without Water?
In America’s fruit and nut basket, water is now the most precious crop of all.
It explains why, amid a historic drought parching much of the American West, a grower of premium sushi rice has concluded that it makes better business sense to sell the water he would have used to grow rice than to actually grow rice. Or why a melon farmer has left a third of his fields fallow. Or why a large landholder farther south is thinking of planting a solar array on his fields rather than the thirsty almonds that delivered steady profit for years.
Opinion: Record-Setting Heat Wave Shows That Climate Change is Creating Hell on Earth
The record-breaking heat wave baking the West Coast is another painful sign that climate change is here, and we have to adapt.
The Pacific Northwest has been sizzling, with conditions forecasters have described as unprecedented and life-threatening. Portland, Ore., hit 113 degrees Monday, breaking the previous all-time high of 112 degrees, set Sunday. About 100 miles to the south, in Eugene, the U.S. track and field Olympic trials were halted Sunday afternoon, and spectators were asked to evacuate the stadium, due to the extreme heat.
California’s Drought and Wildfire Dangers Rising at Stunning Pace
California’s drought and wildfire conditions are accelerating at unprecedented rates, according to state officials, and residents should brace for a summer of widespread burning and mandatory water conservation measures in some regions.
As reservoir levels across the state continue to drop, and as parched vegetation poses an increasing threat of wildfire, officials in Sacramento and Southern California offered a bleak assessment of the state’s drying climate, saying it has already begun to affect people, plants and animals.
Drought Woes in Dry US West Raise July 4 Fireworks Fears
Many Americans aching for normalcy as pandemic restrictions end are looking forward to traditional Fourth of July fireworks. But with a historic drought in the U.S. West and fears of another devastating wildfire season, officials are canceling displays, passing bans on setting off fireworks or begging for caution.
Fireworks already have caused a few small wildfires, including one started by a child in northern Utah and another in central California. Last year, a pyrotechnic device designed for a baby’s gender reveal celebration sparked a California blaze that killed a firefighter during a U.S. wildfire season that scorched the second-highest amount of land in nearly 40 years.
Some regions of the American West are experiencing their worst drought conditions in more than a century this year, said Jennifer Balch, director of Earth Lab at the University of Colorado.
Severe Heat, Drought Pack Dual Threat to Power Plants
Record-setting heat and drought gripping the western United States are exposing a potentially severe risk to the nation’s long-term power supply, and experts warn that grid operators lack sufficient tools to plan and carry out a defense.
A future of worsening water scarcity in heat-blistered parts of the United States could imperil fossil fuel power plants and nuclear reactors that depend on enormous quantities of fresh water in their operations, according to a report by a group of analysts from the Energy Department’s National Renewable Energy Laboratory and other researchers.
As Climate Change Turns Up The Heat in Las Vegas, Water Managers Try to Wring New Savings to Stretch Supply
Las Vegas, known for its searing summertime heat and glitzy casino fountains, is projected to get even hotter in the coming years as climate change intensifies. As temperatures rise, water demand for the desert community is expected to spike. That is not good news in a fast-growing region that depends largely on a limited supply of water from an already drought-stressed Colorado River. Authorities are responding by aiming to wring more water savings out of everything from ice machines and grassy medians to industrial cooling towers, an aggressive conservation effort that could provide examples for communities throughout the Southwest.
Water Shortages: Why Some Californians are Running Out in 2021 and Others Aren’t
In Los Angeles, people have been hearing about the dangers of drought for decades. But in this land of infinity pools and backyard putting greens — better suited for rattlesnakes and scrub — water never seems to run out.
Yet little Redwood Valley in Mendocino County, which gets a bountiful 38 inches of rain in an average year and sits near the headwaters of the Russian River, has been devastated by this year’s drought. Each resident has been told to use no more than 55 gallons per day — enough to fill a bathtub and flush a toilet six times.
And in San Jose, where less than half of its usual rain has fallen this year, people have been asked to cut water use by 15% — a target that could become mandatory if locals fail to comply.
When it comes to the impact of drought, location is key. Rain and snow vary greatly across California’s myriad microclimates, leaving some towns, mostly in the north, accustomed to yearly refills of their rivers, reservoirs and aquifers. Others farther south have fewer natural supplies of their own, and in parts of the Central Valley, the drought never really left.
NASA Images Show Effects of Drought on California’s Largest Reservoirs
Satellite images recently released by NASA show how drought has affected Northern California’s Shasta Lake and Lake Oroville, the largest reservoirs in the state. NASA compared images taken earlier in June with images taken in the summer of 2019 to illustrate how water levels have declined over the two-year period.
Against Expectations, Southwestern Summers Are Getting Even Drier
The Southwest, already the driest region in the United States, has become even drier since the mid-20th century, particularly on the hottest days, according to new research. Humidity has declined in summers over the past seven decades, the research showed, and the declines have accelerated since 2000, a period of persistent drought in the region. Extreme heat coupled with lower humidity increases wildfire risk, said Karen McKinnon, a climate scientist at the University of California, Los Angeles, and lead author of a paper in Nature Climate Change describing the research and findings.
