MLRA 58B - Northern Rolling High Plains, Southern Part Montana and Wyoming 50,810 km2 (19,620 mi2)

Water:
The low and erratic precipitation is the principal source of water for agriculture. Water for livestock is stored in small reservoirs, but supplies are inadequate for significant irrigation. Irrigation water in quantity is available only along the major rivers and some of their larger tributaries. Ground water is scarce in most of the area, but in places, sand and gravel deposits and coalbeds yield small to moderate amounts.
