Guided by bad science, regulators are flushing away millions of gallons of water to protect a three-inch fish.
In California, it takes about 1.1 gallons of water to grow an almond; 1.28 gallons to flush a toilet; and 34 gallons to produce an ounce of marijuana. But how many gallons are needed to save a three-inch delta smelt, the cause célèbre of environmentalists and bête noire of parched farmers?
To protect smelt from water pumps, government regulators have flushed 1.4 trillion gallons of water into the San Francisco Bay since 2008. That would have been enough to sustain 6.4 million Californians for six years. Yet a survey of young adult smelt in the Sacramento-San Joaquin River Delta last fall yielded just eight fish, the lowest level since 1967. An annual spring survey by state biologists turned up six smelt in March and one this month. In 2014 the fall-spring counts were 88 and 36. While the surveys are a sampling and not intended to suggest the full population, the U.S. Fish and Wildlife Service warns that “the delta smelt is now in danger of extinction.”
