Abstract
Western Montana is a region of high mountain ranges separated by broad valleys partly filled with up to several thousands of feet of unconsolidated to semiconsolidated sediments in which are stored enormous quantities of water. In the Missoula Valley a relatively small amount of this water, perhaps 20%, is stored in aquifers within the upper five or six hundred feet of the land surface, where some of it is now being discharged through wells. Recharge to these shallow aquifers is mostly by infiltration from surface runoff, irrigation and snow melt. The ultimate objective of this study was to help determine efficient guidelines for managing this valuable resource. The immediate objective was to study the ground water circulation patterns and recharge discharge relationships of the ground water aquifers as revealed by the age of the water stores therein and by local geohydrologic controls.
