MLRA 44 - Northern Rocky Mountain Valleys Idaho, Montana, and Washington 32,320 km2 (12,480 mi2)

Water:
Perennial streams flowing into the area from surrounding mountains are the principal source of water. The amount usually is adequate but depends on the snow accumulation in the mountains. Ground water is abundant in the deeper unconsolidated fill materials, and some is used for irrigation. Precipitation is adequate for some dryfarming at higher elevations and throughout the area in northern Idaho.
