 SURFACE WATER QUANTITY 



Streamflow 



Streamflow in the Poplar River basin was near normal during 1986, 

 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 17,100 cubic deca- 

 metres (dam^), or 105 percent of the long-term average. A comparison 

 of the flows of 1986 with those of the 1951-80 median flow is shown 

 in Figure 2.

Figure 2. — Discharge during 1986 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 1986 was 9,450 dam^, or 77 percent of the mean annual 

 flow since the completion of Morrison Dam in 1975.
