Reading the Sky: Drought, Irrigation and the Missouri's Water

In a state where most crops drink only what the clouds provide, the recurring specter of drought keeps every grower's eye on the rain gauge — and turns some toward the water of the Missouri.

The great majority of North Dakota's cropland is dryland — farmed on whatever moisture the sky sees fit to deliver — and so drought is the oldest and most implacable of the grower's adversaries. A dry spring, a rainless July, a run of hundred-degree afternoons, and a promising crop can burn to a light and shriveled kernel before the combine ever starts.

Between the Rain Gauge and the River

Along the Missouri and above the aquifers, some growers irrigate, drawing on the river that the great dams pooled into Lake Sakakawea. But irrigation is dear, and the infrastructure reaches only a fraction of the cropland, so for most of the plains the answer to drought remains the same as it ever was: conserve every drop of snowmelt, and hope.

From the almanac's reckoning:

  • The great majority of North Dakota cropland is unirrigated dryland.
  • Lake Sakakawea, pooled by dams on the Missouri, supplies some irrigation.
  • Snowmelt conservation remains the dryland grower's chief defense against drought.

The almanac has never pretended to command the rain. It offers instead the old counsel — bank moisture with stubble, choose drought-hardy crops, and carry a reserve through the fat years against the lean. On the plains, water is the one account that cannot be overdrawn.
