Climate change and drought will impact San Diego County’s climate future, but regional water supply planning and adaptation measures will ensure a safe, reliable supply for the region.
Water supply strategy was one of the key points participants learned about during a Monday panel discussion, “San Diego County’s Climate Future,” hosted online by the San Diego County Water Authority, Citizens Water Academy, Leaders 20/20 and San Diego Green Drinks.
After two exceptionally dry California winters, the East Bay Municipal Utility District is on the brink of declaring a stage 1 drought and asking customers to establish a district-wide voluntary water use reduction of 10 percent.
The utility district’s board of directors is meeting Tuesday night and district staff members will present the 2021 Water Supply Availability and Deficiency Report and make the recommendation.
Arizona may be facing its first official declaration of water shortage next year, a move that would trigger water cutbacks of 512,000 acre-feet — almost 20% of Arizona’s Colorado River entitlement — affecting mainly agricultural users.
The 24-Month Study on the Colorado River system, released this month by the Bureau of Reclamation, projects that in June water levels in Lake Mead will fall below 1,075 feet for the first time, which would put the state in a Tier 1 shortage.
Some Colorado River tribulations today remind me of a folk story: A young man went to visit his fiancé and found the family trembling and weeping. They pointed to the ceiling, where an axe was embedded in a rafter.
The long-term drought and effects of climate change means more trouble for the millions of people that depend on the Colorado River.
In a statement released in early April, the Arizona Department of Water Resources, and the Central Arizona Project state that they expect the first-ever shortage declaration for the river in 2022, meaning substantial cuts to Arizona’s share of the water supply.
Scientists have few categories at their disposal to describe droughts, which are more complex than mere shortages of precipitation or surface water. For example, some local shortages can be invisible, as when water is transferred into a dry area from a distant source. Other shortages are chronic, with communities continuously requiring more water than is available, even in wet years. Some water shortages occur when water quality becomes so degraded that even though there may be plenty of water available, little of it is usable. With such variation in conditions, scientists need better language to conceptualize droughts.
The California State Water Resources Control Board Friday urged people and their pets to avoid the water in the Salton Sea due to a toxic algae outbreak.
Officials said that patches of toxic cyanobacteria have been discovered at numerous sites in the sea, and a dog recently died after swimming in the water.
The U.S. Supreme Court on Monday instructed the Imperial Irrigation District to submit a response to California farmer Michael Abatti’s request that their longstanding legal battle be taken up by the nation’s highest court.
Scott Harris, clerk of the Supreme Court, wrote to Jennifer Meeker, an attorney for the water and power district, to say that even though IID didn’t feel the need to answer Abatti’s petition, “the Court nevertheless has directed this office to request that a response be filed.”
Vicente Calderon from Tijuana Press and I spend a lot of time picking our way around the sewage-laden Tijuana River, asking ourselves: How is it still this bad? Our latest story from the cross-border sewage crisis plaguing Tijuana and San Diego illuminated that the current approach to solving the problem is a lot like putting a Band-Aid on the stomach flu. The Band-Aid in this case is $300 million that Congress has charged the Environmental Protection Agency with deciding how to spend. But really, and here’s the flu part of the allegory, a lot of Tijuana’s infrastructure is just old and broken, or was never even built to support the neighborhoods that popped up on its hillsides.
The San Diego County Water Authority’s board has directed its staff to explore opportunities to help other water districts weather an emerging drought across California.
The authority said that because of three decades of investment in supply reliability, along with a continued emphasis on water-use efficiency, the San Diego region has sufficient water supplies for multiple dry years.
Those investments include high-priority Colorado River water from the Imperial Valley, seawater desalination, and access to the Semitropic Original Water Bank in Kern County, where the authority has stored about 16,000 acre-feet of water — enough to supply more than 30,000 homes for a full year.
