The general principle of the Master Agreement on Apportionment (as outlined in Paragraph 3, Schedule A) states: "Alberta shall permit a
quantity of water equal to one-half of the natural flow (less U.S.A. diversions) of each watercourse to flow into the Province of Saskatchewan ...
However, in the case of the South Saskatchewan River, the Agreement lists a number of additional conditions that include a minimum flow requirement (equal to the
lesser of 50% of natural flow or 1,500 cubic feet per second) at the Saskatchewan boundary. The flow is apportioned equitably.
