Figure 3.1 Discharge during 1992 as Compared with the IVIedian Discharge 

 from 1961-1990 for the Poplar River at the International Boundary. 



The 1992 recorded flow volume of the East Poplar River at the International Boundary was 1 860 

 dam-^. This volume is 54 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
