Water:
In most years, moisture is inadequate for maximum crop production. The Missouri River is the only dependable source of water for irrigation; therefore, irrigated cropland is mostly confined to a narrow band along its valley. There is a limited supply of ground water. Most water for livestock comes from dug ponds.
