Prairie Provinces Water Board

Runoff from the eastern slopes of the Rocky Mountains is the major water supply for the large southern rivers of the prairie provinces. These rivers flow eastward across Alberta, Saskatchewan and Manitoba to empty into Hudson Bay.

The ownership of the waters of a river system flowing through several jurisdictions can give rise to many administrative and water use problems. To resolve conflicts between upstream uses and downstream needs, Alberta, Saskatchewan, Manitoba and Canada signed the Prairie Provinces Water Board Agreement on July 28, 1948.

The mandate of the Prairie Provinces Water Board is to ensure eastward flowing interprovincial streams are, in accordance with the provisions of that Agreement, shared equitably, that water quality at interprovincial boundaries is maintained at acceptable levels, and to facilitate a cooperative approach for the integrated development and management of interprovincial streams and aquifers to ensure their sustainability.
