3J.1 Operations 



SaskPower's supplementary supply continued to operate during 2000, with the majority of ground-water 

 production occurring during the fall to spring period. This is a typical operational pattern for the project 

 and is done to minimize water losses. Limited production occurs during the summer months in order to 

 supply domestic users, including the Town of Coronach. In 2000, ground- water production increased to 

 4,907 dam^ from the 1999 total of 4,410 dam^ total. Production from 1991 to 2000 has now averaged 

 5,026 dam^ per year. Prior to 1990, the wells used for supplementary supply were part of a dewatering 

 network for coal-mining operations. This resulted in the high production levels experienced in the early 

 to mid 1980's. With the drought of the late 1980's and early 1990's, it was evident that there was a 

 continued need for groxmd water to supplement water levels in Cookson Reservoir. Consequently the 

 wells were taken over by SaskPower for use as a supplementary supply.
