MLRA 54 - Rolling Soft Shale Plain Montana, North Dakota, and South Dakota 58,100 km2 (22,430 mj2)

Water:
In most years the supply of moisture is inadequate for maximum crop production. Water for irrigation is available in quantity only from the Missouri River and a few of its larger tributaries. Water for livestock is stored in small reservoirs on uplands. A small area of sand and gravel yields moderate quantities of ground water. Ground water is scarce or is lacking in areas underlain by shale.
