The Scorching of California

The drought has threatened to turn large tracts of farmland into dust.
In mid-December, the first large storms in three years drenched California. No one knows whether the rain and snow will continue—only that it must last for weeks if a record three-year drought, both natural and man-made, is to end. In the 1970s, coastal elites squelched California’s near-century-long commitment to building dams, reservoirs, and canals, even as the Golden State’s population ballooned. Court-ordered drainage of man-made lakes, meant to restore fish to the 1,100-square-mile Sacramento–San Joaquin River Delta, partly caused central California’s reservoir water to dry up. Not content with preventing construction of new water infrastructure, environmentalists reverse-engineered existing projects to divert precious water away from agriculture, privileging the needs of fish over the needs of people. Then they alleged that global warming, not their own foolish policies, had caused the current crisis.
Even as a fourth year of drought threatens the state, canal water from the Hetch Hetchy reservoir in Yosemite National Park keeps Silicon Valley and the San Francisco Bay Area a verdant oasis. This parched coastal mountain range would have depopulated long ago without the infrastructure that an earlier, wiser generation built and that latter-day regulators and environmentalists so casually deprecated. (See “California’s Promethean Past,” Summer 2013.) Gardens and lawns remain green in Palo Alto, San Mateo, Cupertino, and San Francisco, where residents continue to benefit from past investments in huge water transfers from inland mountains to the coast. They will be the last to go dry.
grew up in the central San Joaquin Valley during the 1950s. In those days, some old-timers remembered with fondness when the undammed Kings River’s wild, white water would gush down into the sparsely populated valley. But most Californians never had such nostalgia. Past generations accepted that California was a growing state (with some 20 million people by 1970), that agriculture was its premier industry, and that the state fed not just its own people but millions across America and overseas. All of that required redistribution of water—and thus dams, reservoirs, and irrigation canals.
For 50 years, the state transferred surface water from northern California to the Central Valley through the California State Water Project and the federal Central Valley Project. Given these vast and ambitious initiatives, Californians didn’t worry much about the occasional one- or two-year drought or the steady growth in population. The postwar, can-do mentality resulted in a brilliantly engineered water system, far ahead of its time, that brought canal water daily from the 30 percent of the state where rain and snow were plentiful—mostly north of Sacramento as well as from the Sierra Nevada Mountains—to the lower, western, and warmer 70 percent of the state, where people preferred to work, farm, and live.
Everyone seemed to benefit. Floods in northern California became a thing of the past. The more than 40 major mountain reservoirs generated clean hydroelectric power. New lakes offered recreation for millions living in a once-arid state. Gravity-fed snowmelt was channeled into irrigation canals, opening millions of new acres to farming and ending reliance on pumping the aquifer. To most Californians, the irrigated, fertile Central Valley seemed a natural occurrence, not an environmental anomaly made possible only through the foresight of a now-forgotten generation of engineers and hydrologists.
Just as California’s freeways were designed to grow to meet increased traffic, the state’s vast water projects were engineered to expand with the population. Many assumed that the state would finish planned additions to the California State Water Project and its ancillaries. But in the 1960s and early 1970s, no one anticipated that the then-nascent environmental movement would one day go to court to stop most new dam construction, including the 14,000-acre Sites Reservoir on the Sacramento River near Maxwell; the Los Banos Grandes facility, along a section of the California Aqueduct in Merced County; and the Temperance Flat Reservoir, above Millerton Lake north of Fresno. Had the gigantic Klamath River diversion project not likewise been canceled in the 1970s, the resulting Aw Paw reservoir would have been the state’s largest man-made reservoir. At two-thirds the size of Lake Mead, it might have stored 15 million acre-feet of water, enough to supply San Francisco for 30 years. California’s water-storage capacity would be nearly double what it is today had these plans come to fruition. It was just as difficult to imagine that environmentalists would try to divert contracted irrigation and municipal water from already-established reservoirs. Yet they did just that, and subsequently moved to freeze California’s water-storage resources at 1970s capacities.
All the while, the Green activists remained blissfully unconcerned about the vast immigration into California from Latin America and Mexico that would help double the state’s population in just four decades, to 40 million. Had population growth remained static, perhaps California could have lived with partially finished water projects. The state might also have been able to restore the flow of scenic rivers from the mountains to the sea, maintained a robust agribusiness sector, and even survived a four- or five-year drought. But if California continues to block new construction of the State Water Project as well as additions to local and federal water-storage infrastructure, officials must halve California’s population, or shut down the 5 million acres of irrigated crops on the Central Valley’s west side, or cut back municipal water usage in a way never before done in the United States.
