Figure 3. 1 Discharge during 1995 as Compared with the Median Discharge from 1931- 

 IS^ for Poplar River at the International Boundary. 



The 1995 recorded flow volume of the East Poplar River at the International Boundary was 2 530 

 dam'. This volume is 85 % 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 recommoidation to the Governments of Canada and 

 the United States regarding the aj^rtionment 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 the International Boundary from March 1 to May 31, 

 1995 was 2 110 dam^ Based on UC 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 of 

 0.028 mVs for the period June 1, 1995 to May 31, 1996. The minimum flow for the period 

 January 1 to May 31, 1995 had previously been determined on the basis of the Poplar River flow 

 volume for March 1 to May 31, 1994. A hydrograph of the East Poplar River at the International 

 Boundary and the minimum flow as recommended by the UC are shown in Figure 3.2.
