The last day of January looked like a banner day for Arizona’s water planning. State lawmakers had passed legislation authorizing Arizona to enter into an important deal. Gov. Doug Ducey signed the bills almost immediately. “Working together with a common goal in mind, there’s no limit to what we can achieve. And today proves it,” he pronounced.
Thanks to a series of recent snow storms, drought conditions in Colorado have shown substantial improvements over the past month, including the past week, with extreme drought nearly disappearing from the state. A remaining sliver of exceptional drought – the worst category – in southwest Archuleta County disappeared in the latest report from the National Drought Mitigation Center.
Monday is the new deadline for all parties to sign the drought contingency plan — the deal between seven states to share less water on the Colorado River. Arizona state lawmakers approved the deal ahead of a late January deadline but the federal government said it didn’t meet the mark. Meanwhile, some say the plan doesn’t go far enough to ensure Arizona has enough water for the future.
The U.S. Drought Monitor (USDM) is released weekly to indicate what areas throughout the United States are experiencing some level of the five-category drought. The USDM levels range from the lower end of Abnormally Dry to the highest level of drought, Exceptional Drought. During the recent five-year drought, which ended with the record-setting winter of 2016-17, Californians were faced with water shortages and much of the state ranked in the Extreme and Exceptional categories.
Back-to-back storms hammering California this winter have nearly washed drought off the California map. After the recent atmospheric river, only a lingering sliver of “moderate drought” conditions remains near the Oregon border. The federal Drought Monitor Map, one way to measure drought that’s mainly used in agriculture, shows two percent of the state with “moderate drought” conditions and 13 percent abnormally dry in its Feb. 28 report.
Ten years ago, the state and region were facing a water crisis — snowpack levels were below normal and water restrictions were in place.
Thinking outside the box, the Water Authority sweetened its conservation outreach efforts by partnering with the San Diego-Imperial Council of the Girl Scouts to distribute water conservation tip sheets across the region with the scouts’ popular cookies.
In March 2009, 400,000 conservation cards were handed out with 2 million boxes of cookies. “Please take a few moments to implement one or more saving tips,” the cards said. “The amount of water saved could have a huge impact on our region!”
This partnership was part of a $1.8 million outreach program that helped the San Diego region prepare for potential water supply allocations. The campaign was the Water Authority’s largest advertising and marketing effort since the early 1990s.
What a difference a winter can make. On Jan. 1, three-quarters of California was in drought. Just eight weeks later, however, a succession of storms have washed drought conditions away from all but a splotch at the far north edge of the state, according to the U.S. Drought Monitor. Some of Southern California is still considered abnormally dry, which means there are some lingering water deficits. Considering what the state has been through in recent years, this is good news.
A California irrigation district with the highest-priority rights to Colorado River water is using its power to demand federal funds to restore the state’s largest lake, hoping to capitalize on one of its best opportunities to tackle a long-standing environmental and human health hazard. The Imperial Irrigation District wants $200 million for the Salton Sea, a massive, briny lake in the desert southeast of Los Angeles created when the Colorado River breached a dike in 1905 and flooded a dry lake bed. The money would help create habitat for migratory birds and suppress dust in communities with high rates of asthma and respiratory illnesses.
Drought conditions have dramatically improved this winter in the West and this trend is expected to persist into the spring. A dominate weather pattern featuring a southward dip in the jet stream, or upper-level trough over the western U.S., has allowed a series of precipitation-rich storm systems to track through the region, especially over the last month.
With every storm this winter, climatologists and water managers have crossed their fingers, hoping for continued rain and snowfall to cushion the state’s water supply. So far, the streak has held. This week is expected to bring the heaviest rainfall of the season to date, adding to an already wet winter that has replenished reservoirs and created a healthy snowpack in the Sierra Nevada, a major source of California’s water supply. Climatologist Michael Anderson said that after hovering just below average precipitation levels, the state has now reached above-usual levels — with an average of 11.85 inches of precipitation across the state from October through January.
