[Ed. – Yes, this means we need to control our borders as well as building an adequate water infrastructure for 40 million Californians.]
California droughts are both age-old and common. Predictable California dry spells — like those of 1929–34, 1976–77, and 1987–92 — are more likely result from poorly understood but temporary changes in atmospheric pressures and ocean temperatures.
What is new is that the state has never had 40 million residents during a drought — well over 10 million more than during the last dry spell in the early 1990s. Much of the growth is due to massive and recent immigration.
A record one in four current Californians was not born in the United States, according to the nonpartisan Public Policy Institute of California. Whatever one’s view on immigration, it is ironic to encourage millions of newcomers to settle in the state without first making commensurately liberal investments for them in water supplies and infrastructure. …
[E]nvironmentalists in the last 40 years canceled most of the major second- and third-stage storage projects. To take a few examples, they stopped the raising of Shasta Dam, the construction of the Peripheral Canal, and gargantuan projects such as the Ah Pah and Dos Rios reservoirs.
Lower foothill dams such as the proposed Sites, Los Banos, and Temperance Flat dams in wet years would have banked millions of acre-feet as insurance for dry years. All such reservoirs were also canceled. Yet a single 1 million acre-foot reservoir can usually be built as cheaply as a desalinization plant. It requires a fraction of desalinization’s daily energy use, leaves a much smaller carbon footprint, and provides almost 20 times as much water.
