Federal authorities are expected to declare a water shortage for Lake Mead Monday, which would trim Nevada’s allocation of water in 2022.
A shortage gets triggered if the lake is expected to sit below 1,075 feet on January 1, 2022. As of Wednesday morning, the lake sits at 1,067.93 feet. The shortage has been anticipated as Lake Mead’s water level continues to drop.
In the American West, water has always been a challenge. Prior to the arrival of European explorers and settlers, there’s broad evidence that droughts and water cycles heavily affected Native Americans. For example, the people who built the Gila Cliff Dwellings may have left the area when water supplies dwindled. Later settlements by the descendants of Europeans also followed water, with settlements placed near rivers so there would be something to drink and grow food with.
If the Colorado River were a bank account, it would be running toward the red.
The river, the lifeblood for several Western states, is being squeezed by overuse and plunging supply — as temperatures stay on the upswing year after year, and thirsty soils rapidly absorb the bulk of moisture from a dwindling annual snowpack.
The conclusion is “inescapable,” Colorado River District Manager Andy Mueller said Monday.
The “bathtub ring” at Lake Mead has become a familiar sight. The water level in the lake is the lowest it has been since the Hoover Dam, which created the lake, was built in the 1930s. Those low levels have been decades in the making.
“Back in around 2000, Lake Mead was pretty close to being full, but over the last 20 years-plus now we’ve just not had good hydrologic conditions. It will take years to recover from that, years of good conditions and unfortunately the climate models and projections don’t predict us getting cooler and they don’t predict us, let’s say, getting wetter,” said Dr. Sharon Megdal, University of Arizona professor and former board member for the Central Arizona Project.
Seeking to stave off legislation that would force Riverside County representation on its board of directors, the Imperial Irrigation District on Thursday convened the first meeting of its new Coachella Valley Energy Commission.
Undera long-term agreement with the Coachella Valley Water District, IID provides electrical power to 100,000 Coachella Valley residents. That pact expires in 2033, and the new commission’s overarching goal is to hammer out a way forward for those customers.
“As we approach the end of a 99-year arrangement … we must work together and adapt to changing circumstances and plan for a future of mutual benefit,” said IID Board of Directors Vice President J.B. Hamby, who chairs the new commission. “That’s not just overcoming perceived differences between Coachella and Imperial Valleys, but within the Coachella Valley as well. Our task is to overcome geography, wealth, backgrounds, and past differences as we plan our shared future.”
More than 40 million people rely on the Colorado River in the West, and every drop of it is used. But with climate change, there’s now less water to go around. To try and avoid a multi-state legal battle over this precious resource, Colorado and other states are considering paying people to keep more water in the river.
In southwest Gunnison County, farmers and ranchers rely on water that would otherwise end up in the Colorado River. Drought has plagued the area for more than 20 years, so the resource is now more valuable than ever.
The cotton’s gone.
The alfalfa barely exists.
“Can you even call this a farm?” asked Nancy Caywood, standing on a rural stretch of land her Texas grandfather settled nearly a century ago, drawn by cheap prices and feats of engineering that brought water from afar to irrigate central Arizona’s arid soil.
Water levels at Lake Powell have dropped to their lowest level since the huge reservoir was filled more than 50 years ago, another sign of the ongoing drought’s toll on the Colorado River. The reservoir fell to 3,555.09 feet above sea level Friday and continued to drop through the weekend, according to the U.S. Bureau of Reclamation. As of late Sunday, water levels stood at 3,554.72 feet. The previous low mark, set in 2005, was 3,555.10 feet. Friday’s low water mark comes barely a month after Lake Mead, the largest reservoir on the river, reached a record low. Federal officials are expected next month to declare a water shortage on the Colorado River, triggering cutbacks next year in Arizona and Nevada.
A southern Utah city plans to pull additional water from the Colorado River, but the move amid a historic drought has left some concerned. A 140-mile pipeline approved by the Utah Legislature would serve St. George, a fast-growing city of nearly 90,000 people — up from fewer than 75,000 a decade ago. A new “straw” into the river would increase demand on the Colorado River system, even as federal officials deal with a shrinking Lake Powell, which would be the source of the pipeline.
It has lasted longer than the Dust Bowl of the 1930s. It’s dropped water levels perilously low at two of the nation’s largest reservoirs, forced ranchers to sell off herds and helped propel scorching wildfires. And worst of all, the drought blanketing the western United States is not going away. A group of experts featuring federal and state officials and farmers and ranchers spent nearly three hours yesterday chronicling the devastation caused by drought conditions that now cover almost every inch of seven Western states. Half of the U.S. population lives in a drought-stricken area.
