SURFACE WATER QUANTITY 



Streamflow 



Streamflow in the Poplar River basin was below normal during 1985, 

 assuming the recorded flow of the Poplar River at the International 

 Boundary is a good indicator of basin runoff conditions. The March to 

 October recorded flow volume at that gauge was 7 710 cubic decametres 

 (dam3), or 47 percent of the long-term average. A comparison of the flows 

 of 1985 with those of the 1951-80 median flow is shown in Figure 2.

Figure 2 - Discharge during 1985 compared with median discharge for 

 1951-80 for the Poplar River at International Boundary. 



The recorded flow volume of the East Poplar River at the International 

 Boundary for 1985 was 2 980 dam^, or 21 percent of the mean annual flow 

 since the completion of Morrison Dam in 1975.
