Table 3.4 Cookson Reservoir Storage Statistics for 1995 



The Poplar River Power Station is dependent on water from Cookson Reservoir for cooling. 

 Power plan operation is not adversely affected until reservoir levels drop below 749.0 metres. 

 The dead storage level for cooling water used in the generation process is 745.0 metres. The 1995 

 recorded levels and associated operating levels are shown in Figure 3. 15. As the result of a below 

 normal spring runoff in the basin and some minor rainfall runoff during the summer, water levels 

 remained relatively steady throughout the year.
