In order to manage groundwater carefully, we must first understand it. How much is there? Where is it and where does it flow from and to? Is it good quality water?

Two major groundwater studies the Willow Creek Watershed and the Crowsnest River Watershed illustrate the critical  need for increased groundwater monitoring for managing this important resource.
