The 1 999 recorded flow volume of the East Poplar River at International Boundary was 26,990 dam^ 

 (21,880 acre-feet). This volume is 906 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 Apportionment 

 Recommendations in each of its annual reports. Annex 3 contains the apportionment recommendation. 



3.2.3 Minimum Flows 



The recorded volume of the Poplar River at International Boundary from March 1 to May 31,1 999 was 

 35,440 dam^ (28,730 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 0.085 cubic metres per second (mVs) (3.0 cubic feet per second (ftVs)) for the period June I, 1999 to 

 August 31, 1999 and 0.057 mVs (2.0 ftVs) for the period September 1, 1999 to May 31, 2000. The 

 minimum flow 0.028 mVs (1.0 ftVs) for the period January 1 to May 31, 1999 had previously been 

 determined on the basis of the Poplar River flow volume for March 1 to May 31, 1998. A hydrograph 

 for the East Poplar River at International Boundary and the minimum flow as recommended by the IJC 

 are shown in Figure 3.2. 



Daily flows during 1999 met or exceeded the minimum flow recommended by the IJC throughout the 

 year except for July 27 to August 8, August 14-18, and August 21 -26 when daily flows fell slightly below 

 the recommended minimum.
