US farmers fear the return of the Dust Bowl
For years the Ogallala Aquifer, the world’s largest underground body of fresh water, has irrigated thousands of square miles of American farmland. Now it is running dry

07 Mar 2011 There is not much to be happy about these days in Happy, Texas. Main Street is shuttered but for the Happy National Bank, slowly but inexorably disappearing into a High Plains wind that turns all to dust. The old Picture House, the cinema, has closed. Tumbleweed rolls into the still corners behind the grain elevators, soaring prairie cathedrals that spoke of prosperity before they were abandoned for lack of business. Happy’s problem is that it has run out of water for its farms. Its population, dropping 10 per cent a year, is down to 595. The name, which brings a smile for miles around and plays in faded paint on the fronts of every shuttered business – Happy Grain Inc, Happy Game Room – has become irony tinged with bitterness. It goes back to the cowboy days of the 19th century. A cattle drive north through the Texas Panhandle to the rail heads beyond had been running out of water, steers dying on the hoof, when its cowboys stumbled on a watering hole. They named the spot Happy Draw, for the water. Now Happy is the harbinger of a potential Dust Bowl unseen in America since the Great Depression. ‘It was a booming town when I grew up,’ Judy Shipman, who manages the bank, says. ‘We had three restaurants, a grocery, a plumber, an electrician, a building contractor, a doctor. We had so much fun, growing up.’ Like all the townsfolk, she knows why the fun has gone. ‘It’s the decline in the water level,’ she says. ‘In the 1950s a lot of wells were drilled, and the water went down. Now you can’t farm the land.’ Those wells were drilled into a geological phenomenon called the Ogallala Aquifer. It is an underground lake of pristine water formed between two and six million years ago, in the Pliocene age, when the tectonic shifts that pushed the Rocky Mountains skywards were still active. The water was trapped below the new surface crust that would become the semi-arid soil of the Plains, dry and dusty. It stretches all the way down the eastern slope of the Rockies from the badlands of South Dakota to the Texas Panhandle. It does not replenish. Happy is the canary in the coalmine because the Ogallala is deepest in the north, as much as 300ft in the more fertile country of Nebraska and Kansas. In the south, through the panhandle and over the border to New Mexico, it is 50-100ft. And around Happy, 75 miles south of Amarillo, it is now 0-50ft. The farms have been handed over to the government’s Conservation Reserve Programme (CRP) to lie fallow in exchange for grants: farmers’ welfare, although they hate to think of it like that. … ‘Since then,’ says David Brauer of the US Agriculture Department agency, the Ogallala Research Service, ‘we have drained enough water to half-fill Lake Erie of the Great Lakes.’ Billions upon billions of gallons – or, as they prefer to measure it, acre-feet of water, each one equivalent to a football field flooded a foot deep – have been pumped. ‘The problem,’ he goes on, ‘is that in a brief half-century we have drawn the Ogallala level down from an average of 240ft to about 80.’ …
