Manitoba shares a number of transboundary watersheds with upstream jurisdictions including Alberta, Saskatchewan, Ontario, North Dakota and Minnesota. Because water does not recognize jurisdictional boundaries and flows across borders, activities and developments including drainage, dams, and diversions across these shared transboundary watersheds can impact downstream water quantity and quality in Manitoba.

Manitoba Environment and Climate Change participates in a number of transboundary boards and committees intended to support cooperation on transboundary water management.

Manitoba also has a number of transboundary agreements in place including:

  • Canada-Manitoba Memorandum of Understanding Regarding Lake Winnipeg and its Basin.
  • Saskatchewan-Manitoba Memorandum of Understanding Respecting Water Management (see attached pdf))
