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

 damVyear. This approval was extended by Saskatchewan Water Corporation in 1996. Future revisions 

 to the approval will likely include conditions requiring termination of pumping (with the exception of 

 wells supplying domestic users) when the reservoir is above a specified level. 



In addition to the supplementary supply, SaskPower also operates the Soil Salinity Project, which is 

 located south of Morrison Dam. The project was initiated in 1989 to alleviate soil sahnity which had 

 developed below the dam. The salinity project consists of a network of production wells which 

 discharge into the cooling water canal, which in turn discharges to Cookson Reservoir. Ongoing 

 operational difficulties with the salinity wells resulted in a continued decline in the aimual volume 

 pumped (Figure 3.13). However, a well-rehabilitation program has been initiated and as a result 

 production in 2004 increased to 557 dam^ from the 426 dam^ pumped from the Soil Salinity Project in 



2003. This volume is still substantially lower than the annual production levels obtained in the early to 

 mid- 1 990 's when production was near its optimal level. 



Well PW87104, which is located on the east side of the river, provided all the production in 2003. In 



2004, production was obtained from wells PW87104 and PW90108. SaskPower expects to continue 

 with the rehabilitation program again in 2005.
