Apportionable flows are calculated for South Saskatchewan River below the junction of the Red Deer River.
The black bar shows the amount of apportionable flows that were required to be delivered by Alberta to Saskatchewan. The white bar shows the flow surplus amounts that were delivered in excess of required flows. The combined black (provincial share) and white (surplus) stacked bars show the total recorded flows. On the y-axis, the number following the "e" in the Scientific Notation shows how many zeros should be placed to the right of the decimal place.
Under the Master Agreement on Apportionment, Saskatchewan's share is 50% of the apportionable flows. Section 2(c) of Schedule A of the Agreement states that Alberta has the option to measure flows of the Red Deer River and South Saskatchewan River below the confluence of the Red Deer River.
These two rivers contribute to the waters that Saskatchewan receives from the same river system so are combined.
Apportionable and recorded flows at the South Saskatchewan River below Red Deer are determined by adding the flows of two nearby sites (Red Deer River near Bindloss, Alberta and South Saskatchewan River at the Alberta-Saskatchewan border).
Alberta has always met their delivery requirements at each of the three apportionment points.
The flow data record for the South Saskatchewan River below the junction of the Red Deer River are provided below. The apportionment point is slightly downstream of the Alberta-Saskatchewan border.
You can copy and paste the flow data into a spreadsheet or word processing file. You can also download the MS Excel file from the right side bar.
