Abstract
Idaho's mountains accumulate snowpack in the winter months, which feeds Idaho's watersheds in the spring and summer months. The gradual melting and runoff during the spring and summer provide streamflow and replenish groundwater for the warmer, drier months. Several major aquifers in Idaho provide significant storage of groundwater. These groundwater resources are vital to the water supply for food production and processing, as well as commercial, household, industrial, and municipal needs. As changes in climate increase, the pattern of water availability for Idaho's economy also will change.
