California’s snowpack is more than two-and-a-half times larger than average right now, according to the state’s Dept. of Water Resources. As the weather gets warmer, it’s going to melt. Geologists say there’s no question we needed the snow.
The Bureau of Reclamation released its 24-Month Study on Thursday, April 20, which includes an increase to downstream flows from Lake Powell to Lake Mead of up to 9.5 million acre-feet (maf) this water year, which runs from (October 1, 2022 through September 30, 2023.
According to a press release from the Bureau of Reclamation, Glen Canyon Dam’s annual release volume for water year 2023 was initially set at 7.0 maf, based on the August 2022 24-Month Study, and is now projected to increase to up to 9.5 maf because of high snowpack this winter and projected runoff in the Colorado River Basin this spring.
Just west of this normally dusty prison town, a civic nightmare is unfolding: Tulare Lake, a body of water that did not exist just two months ago, now stretches to the horizon — a vast, murky sea in which the tops of telephone poles can be seen stretching eerily into the distance.
The San Diego County Water Authority said a new federal report that forecasts significant increases in reservoir levels along the Colorado River is “welcome news” for San Diego’s water supply.
The report released Thursday by the U.S. Bureau of Reclamation forecasts that a near-record snowpack will raise Lake Mead at Hoover Dam by over 20 feet and Lake Powell farther north by 50 feet.
About two-thirds of San Diego County’s supplies are conserved Colorado River water.
Dan Denham, the Water Authority’s deputy general manager, said the federal report “is definitely welcome news and will buy us time to make crucial decisions.”
California’s ongoing floods and very wet year overall will continue to grab headlines, provide great pictures, and break some local records, but overall this year is unlikely to be truly extreme from historical or broader water policy and management perspectives. It can still be a very useful wet year, beyond just having lots of water.
It was the snowpack reading that spawned a hundred headlines. “California ties 1952 record for all-time Sierra snowpack,” proclaimed KTVU. “California’s snowpack soars to record high after 17 atmospheric rivers,” trumpeted the Washington Post.
State officials largely seemed to agree.
A federal report released April 20 says near-record snowpack in the Colorado River Basin could raise the elevation of Lake Mead by more than 20 feet by the end of the year, providing a critical opportunity for water agencies to improve long-term management of the river.
The U.S. Bureau of Reclamation’s report shows vastly improved hydrological conditions are also expected to raise the water level in Lake Powell by more than 50 feet. California relies heavily on lakes Powell and Mead for water, as do Arizona and Nevada.
Despite the good news this year, the ongoing trend toward a hotter and drier climate means long-term solutions remain critical. About two-thirds of San Diego County’s supplies are conserved Colorado River water.
The California Department of Water Resources announced Thursday that the State Water Project will be able to deliver 100% of requested water supplies this year thanks to full reservoirs following record winter rain and snow.
“Invest in Our Planet” is the theme for Earth Day 2023. Investing in sustainable, local water supply sources and conservation has long been a way of life in San Diego County by water agencies and residents.
“Investing in our planet can take many forms, and the challenges we face differ from community to community,” said Water Authority General Manager Sandra L. Kerl. “One investment I encourage San Diegans to think about on this Earth Day is landscape transformation. This is important because the biggest users of water at our homes are our landscapes – perhaps as much as 70% of our water use, depending on where we live.”
Sustainability is a priority of the San Diego County Water Authority and its 24 member agencies. Creating and maintaining a safe, reliable, sustainable water supply for the region ensures the vitality of San Diego County’s $268 billion economy for its 3.3 million residents.
What a difference a month makes.
The March 24-month forecast, which predicts reservoir levels along the Colorado River for the next two years, had Lake Mead on a steady trajectory downward.
