The National Weather Service in Seattle posted a graphic this week that contains a startling fact. Since July 1, Seattle, a city synonymous with rain, has been drier than San Diego, a city synonymous with clear, dry skies.
From July 1 to Oct. 9, San Diego recorded 0.65 inches of rain. Seattle, 1,250 miles to the north, had only 0.48 inches.
The California Coastal Commission is slated to vote Thursday on a crucial permit for a project that would draw ocean water through the sand off the coast of Dana Point, purify it and use it to help bolster water supplies for communities throughout Southern California.
A dozen desalination plants are permitted to turn ocean water into drinking water in California today, from as far south as Carlsbad to as far north as Monterey Bay. A year ago, three new desalination projects were pending in Southern California alone. But only one still remains viable: the Doheny Ocean Desalination Plant, which is being developed by South Coast Water District.
Internationally, the polar bear may be the climate-change canary in a coal mine.
Locally, it could be the avocado.
The fruit so identified with San Diego County agriculture has been on the decline for years. Severe weather, water availability and rising water prices — at least in part attributed to climate change — have reduced the yield of the crop and the revenue it generates.
Plans for a large, high-tech wave pool in La Quinta were recently rejected by its city council, but a handful of other water-centric attractions — including a trio that would feature artificial wave technology — are moving forward in the Coachella Valley.
The projects, which range from Palm Springs in the west to Thermal in the east, have gained approval from elected bodies to move forward. But some say more needs to be done to reduce the parks’ water usage, particularly as California just saw its driest three-year period on record.
Collaboration among all water users is key to developing solutions for the Colorado River Basin, which is in the midst of a 22-year megadrought. That was one of the common themes during a webinar Thursday, in which water managers and other officials discussed ways to slow or stabilize the rate of decline of the major source of water for seven states and Mexico.
Almost two months ago, the seven Colorado River Basin states blew past a federal deadline to negotiate significant cuts to their water usage.
There’s finally some concrete action. Water managers in California, which uses more Colorado River water than any other state, have agreed to reduce their usage by one-tenth in 2023.

“A Collaborative Approach to Colorado River Management,” was part of the Southern California Water Coalition‘s “What Matters” webinar series. The San Diego County Water Authority, Imperial Irrigation District, Black & Veatch, and Richard Brady & Associates sponsored the webinar.

During the 90-minute discussion, speakers said that drought and climate change impacts on the Colorado River Basin have created “challenging times” and that “unprecedented times require unprecendented management” solutions. Solutions mentioned included sustainable conservation, additional storage, a reduction in demand, and inclusion of all users to ensure the long-term health of the river system.
Sandy Kerl, General Manager @sdcwa, highlights that 2/3's of their supply comes from CO River and her top 3 priorities are
1) Balance impact on users while protecting environment (& Salton Sea)
2) Uphold law of the river and priority rights/QSA
3) Expand Lake Mead surplus program— SoCal Water Coalition (@SoCalWaterComm) October 6, 2022
The Water Authority’s supply portfolio includes high-priority, conserved Colorado River supplies negotiated through the landmark 2003 Quantification Settlement Agreement, or QSA. The conserved supplies are the cornerstone of the San Diego region’s long-term water supply diversification strategy.
Chris Harris, Executive Director, Colorado River Board of California, stresses that we need to stop referring to basin conditions as a "drought" – it's aridification. @adelh2o General Manager with @mwdh2o agrees – "We have to adapt to a changing climate."

The webinar came a day after California water agencies that use Colorado River water supplies, sent a letter to the U.S. Department of the Interior and U.S. Bureau of Reclamation, voluntarily offering to reduce their use of water from the river starting in 2023:
“Given dire drought conditions across the region and dangerously low reservoir levels, we firmly believe that all water users within the Basin must take immediate voluntary actions to stabilize water supplies in the Basin’s major reservoirs.
“California water agencies that utilize Colorado River water supplies propose to conserve up to an additional 400,000 acre-feet of water in Lake Mead each year, beginning in 2023 and running through 2026. This water, which would otherwise be used by California’s communities and farms, will meaningfully contribute to stabilizing the Colorado River reservoir system. While a broad multi-state agreement to conserve water across the Basin has not been reached, the California agencies propose to take voluntary action now to conserve water in coming months.”

With the Colorado River in crisis and reservoir levels continuing to decline, California water agencies that depend on the river are planning to significantly reduce their use of water from the river starting next year. As a result, officials with the Metropolitan Water District of Southern California said they plan to endorse mandatory conservation measures next year to begin rationing water for cities and local agencies that supply 19 million people across six counties.
Lake Mead is America’s largest reservoir, supplying water for 25 million people across the southwest. It’s also drying up — a kind of poster child for the ongoing drought in the West. But upstream, a much larger but lesser known source of stored water is also disappearing: mountain snow.
This is how climate change is throwing one of the United States’ most critical sources of water out of whack.
The past three years have been the driest on record in California and officials warn that streak could continue.
Most of the state is under severe-to-exceptional drought conditions, fueling risks for wildfires and putting Central Valley farmers in an even bigger pinch, as they struggle to keep their crops alive.
The weather, in next couple of months, will determine if there will be some relief for the state. Until then, water officials say conservation needs to remain a way of life.
