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

 plant 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 2003 recorded levels 

 and associated operating levels are shown in Figure 3.16.
