An estimated 40 million people rely on water that originates in the Colorado River Basin, but the river can no longer keep up with demand, and it’s raising serious questions about the future of water in the west.
Surrounded by bright orange pumpkins and empty shanks of corn outside his store east of Pueblo, Shane Milberger surveys his field.
States in the Colorado River Basin are adjusting to the reality that their rights outstrip the available water by nearly one-third, state and tribal leaders told a congressional panel last month.
The situation is likely only to worsen as the climate changes, leaving states and tribes in competition for their most vital resource.
The current ongoing two-year dry period in California, punctuated by the third-driest water year on record for the Central Sierra, is part of California’s overall arid fate so far in the 21st century, according to the state Department of Water Resources.
The Golden State’s hydrology now increasingly resembles conditions in the Colorado River Basin this century, where multiple, consecutive, drier-than-average years are mixed with an occasional wet year. California’s last wet water year was 2016-2017, the second-wettest on record.
Green fields of alfalfa and cotton rolled past as Brad Robinson drove through the desert valley where his family has farmed with water from the Colorado River for three generations. Stopping the truck, he stepped onto a dry, brown field where shriveled remnants of alfalfa crunched under his boots.
The water has been temporarily shut off on a portion of Robinson’s land. In exchange, he’s receiving $909 this year for each acre of farmland left dry and unplanted. The water is instead staying in Lake Mead, near Las Vegas, to help slow the unrelenting decline of the largest reservoir in the country.
October marks the beginning of a new calendar for those who measure and manage the west’s water. The good news? Across the Colorado River basin, there’s a lot less “exceptional drought.”
The amount of land under the absolute driest designation is down about 60% in less than a year. The bad news is that more than 90% of the basin remains in some level of drought.
Two years ago, a pact to safeguard the West’s shrinking water supplies took effect at a ceremony high above the Colorado River.
On a terrace overlooking Hoover Dam, water officials from seven states that rely on the river had gathered to sign a deal in hopes of preventing reservoirs from falling to critically low levels.
The cost of getting water from the drought-stressed Colorado River is spiraling and parts of San Diego County with some of the highest bills and big water recycling projects on the horizon seem to be drawing pool noodles together.
That is, in any case, the rough sense that stuck out to me as I re-shuffled through my notes from last week’s story about huge, forecasted increases in the price of Colorado River water, which is controlled by San Diego County Water Authority.
On the bone-dry western flank of Arizona, where the Colorado River Basin meets the Mojave Desert, sit 11,000 acres of alfalfa, sorghum, wheat, and Sudan grass belonging to the Colorado River Indian Tribes (CRIT), all destined to be harvested and sold for animal feed. For anything to grow here, irrigation is a must. Less than a quarter inch of rain has fallen so far this year, according to Josh Moore, who manages the farm on behalf of his tribe.
The 22-year-long drought in the Colorado River Basin is growing more severe. The levels of Lake Mead and Lake Powell are lower than they have ever been. The U.S. Bureau of Reclamation has ordered mandatory cutbacks of water deliveries in 2022 with more cuts predicted in the following two years.
Experts are acknowledging that the river has changed fundamentally: “No doubt climate change is real. We’re seeing it on the Colorado River every day,” as an official quoted in an Aug. 17 Desert Sun article said.
In response to worsening drought conditions, the board of Southern California’s regional water wholesaler and other water agencies across the Southwest have announced a partnership with the federal government to fund a short-term agricultural land fallowing program in California that will conserve water on a large scale.
The partnership among the U.S. Bureau of Reclamation, the Metropolitan Water District of Southern California, Central Arizona Project, Southern Nevada Water Authority, and the Palo Verde Irrigation District is expected to help conserve up to 180,000 acre-feet of water over the next three years, amounting to about a 3-feet increase in Lake Mead’s water level.
