 3.3 Ground-water 



3.3.1 Operations 



In 1995, SaskPower continued to operate their supplementary ground-water supply to Cookson 

 Reservoir. The 1995 total of 5 376 dam? of ground-water produced from the supplementary 

 supply was slightly less than the 1994 production of 5 485 danf . SaskPower has an approval to 

 produce an aimual volimie of 5 500 dam?. 



SaskPower's well network currently consists of 21 wells, with a total of 10 discharge points. No 

 wells were added or deleted from the well field during the year. Production was reasonably 

 consistent throughout most of the year with the exception of July and August when there was a 

 reduction in pumping. In July and August, with the exception of well UA, wells which do not 

 supply water to domestic users were turned off. Therefore, from mid-July to late August, only 

 5-6 wells were pumped, as opposed to the remainder of the year when up to 19 wells were 

 pumped. Reduced summer pumping assists in maximizing flows into Cookson Reservoir by 

 minimizing evaporative losses in Girard Creek and ensures that the SaskPower's allocation is not 

 exceeded. 



Operation of SaskPower's salinity project continued in 1995 with production from 7 wells, with 

 a total volume of 1 017 dan^ pumped during the year. This represents a slight reduction from the 

 1994 pumped volume of 1 095 dam?. (An eighth well is located along the International Boundary, 

 but has never been operated). As in previous years, the majority of the water was pumped from 

 wells PW87103 and PW87104 on the east side of the river and PW90108 on the west side of the 

 river.
