The 2001 recorded flow volume of the East Poplar River at International Boundary was 2,510 dam'' 

 (2,030 acre-feet). This volume is 80 percent of the median annual flow since the completion of 

 Morrison Dam in 1975. 



3.2.2 Apportionment 



In 1976 the International Souris-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 the apportionment of waters of the Poplar River basin. Although not officially adopted 

 by the two countries, the Poplar River Bilateral Monitoring Committee has adhered to the Apportion- 

 ment Recommendations in each of its annual reports. Annex 3 contains the apportiorunent 

 recommendation. 



3.2.3 Minimum Flows 



The recorded volume of the Poplar River at International Boundary from March 1 to May 31, 2001 was 

 4,790 dam"' (3,880 acre-feet). Based on IJC recommendations and the assumption that the recorded flow 

 is the natural flow, the United States was entitled to a minimum discharge on the East Poplar River of 

 0.057 cubic metres per second (m''/s) (2.0 cubic feet per second (ft^/s)) for the period June 1, 2001 to 

 August 31, 2001 and 0.028 m^/s (1.0 ft^/s) for the period September 1, 2001 to May 31, 2002. The 

 minimum flow for the period January 1 to May 31, 2001 was 0.028 m^/s (1.0 ft''/s), determined on the 

 basis of the Poplar River flow volume for March 1 to May 31, 2000. A hydrograph for the East Poplar 

 River at International Boimdary and the minimum flow as recommended by the IJC are shown in Figure 

 3.2. 



Daily flows during 2001 met or exceeded the minimum flow recommended by the IJC throughout the 

 year except for August 7, 1 1, and 12, when daily flows fell slightly below the recommended minimum.
