 apportionment recommendation. 



3.2.3 Minimum Flows 



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

 1992 was 1 460 dam-^. 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 

 0.028 cubic metres per second (m^/s) for the period June 1, 1992 to May 31, 1993. The minimum 

 flow for the period January 1 to May 31, 1992 had previously been determined on the basis of the 

 Poplar River flow volume for March 1 to May 31 , 1 991 . A hydrograph for the East Poplar River at the 

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

 Daily flows during 1992 were above the recommended minimum at all times with the exception of 



December 29, 30, 31, 1992. Extremely cold temperatures reduced the flow to 0.027 m^/s on these 

 days.
