Lodge Creek


Apportionable flows are calculated for Lodge Creek near the Alberta-Saskatchewan border (station 11AB082).

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 red bar indicates amounts of required flows that were not delivered (i.e., deficits).  The combined area indicates recorded flow as the amounts of flow deficits are subtracted from the provincial share.  The required provincial share is the combined area of the black and red bars. 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 principle of equitable sharing in the Master Agreement on Apportionment, Saskatchewan's share of Lodge Creek's apportionable flows is 75% to enable the use of the waters by Saskatchewan and still fulfill Canada's commitments to deliver 50% of the Milk River into the USA. Lodge Creek feeds into the Milk River in Saskatchewan.

Lodge and Middle Creeks are the only two rivers monitored by the PPWB that have not met apportionment requirements. Lodge Creek had small deficits in 1988, 1989, 1992, 1998, and 2000.
