 Apportionment 



In 1976 the International Sourls-Red Rivers Engineering Board, through 

 its Poplar River Task Force, completed an investigation and made a 

 recommendation to the Governments of Canada and the United States 

 regarding an apportionment of waters of the Poplar River Basin. 

 Although not officially adopted by the two countries, the Poplar 

 River Bilateral Monitoring Committee has ascribed to the Apportionment 

 Recommendation in each of its annual reports. Annex 4 contains the 

 Apportionment Recommendation. 



Minimum Flows 



The recorded runoff volume of the Poplar River at the International 

 Boundary from March 1 to May 31, 1986 was 16,100 dam^. For the pur- 

 poses of interpreting the apportionment recommendations of the IJC, 

 the recorded flow is assumed to be the natural flow. Based on these 

 recommendations, this volume entitled the United States to a minimum 

 discharge of 0.085 cubic metre per second (m-'/s) from June 1 to Aug- 

 ust 31, 1986 and 0.057 m^/s from September 1, 1986 to May 31, 1987 

 on the East Poplar River at the International Boundary. The minimum 

 flow of 0.028 m^/s for the first 5 months of 1986 had previously 

 been determined on the basis of the March 1 to May 31, 1985 Poplar 

 River flow volume.
