Summary: The program starts in the Alberta Rockies where alpine snow-melt forms the major tributaries of the South Saskatchewan River System. Water from the river supports irrigation, livestock, energy developments and cities, but cropland has changed the interaction of soils and water. Runoff carries agricultural chemicals from farm fields to the river, degrading the aquatic ecosystem. The upland ecosystem responds to wet and dry years and erratic climatic events influence the intensity of pest and disease outbreaks. Studies of tree rings in the Cypress Hills clearly show that through the centuries, climate and river are intimately linked. To be successful, human activity must recognize and respect these links.
