SaskPower has an approval for the supplementary supply project to produce an annual volume of 5,500 

 dam''/year. The supplementary supply 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. 



In addition to the supplementary supply, SaskPower also operates the Soil Salinity Project south of 

 Morrison Dam. The project was initiated in 1989 to alleviate soil salinity which had developed below 

 the dam. The salinity project consists of a network of production wells discharging into the cooling 

 water canal. This in turn discharges to Cookson Reservoir. Ongoing operational difficulties with the 

 salinity wells resulted in a continued decline in the annual volume pumped (Figure 3.13). However, a 

 well rehabilitation program has been initiated and as a result production in 2005 was 790 dam'' This 

 represents a significant increase from 557 dam^ in 2004 and 426 dam^ in 2003. The majority of water 

 pumped came from wells on the east side of the river. The 2005 production level was still substantially 

 lower than the peak production level of almost 1,100 dam'' in 1994. In 2003 all production was from one 

 well, but this increased to six wells in 2005. In 2006, one well will be decommissioned and an 

 additional well will be rehabilitated.
