HIGHLIGHTS FOR 1995 



The Poplar River Power Station completed its twelfth full year of operation in 1995. The two 

 300-megawatt coal-fired units generated 4 472 200 gross megawatt hours of electricity which is 

 about 102 percent of the 1994 power and 103 percent of 1993 power. The average capacity 

 factors for Units No. 1 and 2 was 87.2 percent and 85.3 percent, respectively. 



Monitoring information collected in both Canada and the United States during 1995 was exchanged 

 in the spring of 1996. In general, the sampling locations, frequency of collection, and parameters 

 met the requirements identified in the 1995 Technical Monitoring Schedules set forth in the 1994 

 annual report. 



Streamflow in the Poplar River basin was below normal in 1995. The March to October recorded 

 flow for the Poplar River at the International Boundary was 3 340 danf or 33 per cent of the 1931 

 to 1990 median seasonal flow. The 1995 recorded flow volume of the East Poplar River at the 

 International Boundary was 2 530 dam^ This volume is 85 per cent of the median annual flow 

 since the completion of the Morrison Dam in 1975. The on-demand release, in accordance with 

 the apportionment recommendations of the International Joint Commission (UC), entitled 

 Montana to a release of 617 dam^ from Cookson Reservoir during the twelve month period 

 commencing June 1, 1994. Montana requested this release to be made between April 11 and May 

 31, 1995. In addition to the minimum flow, a volume of 628 danf was delivered during this 

 period. 



It is noted that the 5-year moving flow-weighted concentrations of total dissolved solids for the 

 East Poplar River at the International Boundary were continuing to approach the 1 000 milligrams 

 per litre objective. The calculated 5-year flow-weighted concentration of total dissolved solids for 

 1995 was 989 milligrams per litre. However, the concentration of boron for 1995 was 1.84 

 milligrams per litre, below its objective of 2.5 milligrams per litre.
