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

 darn's/year. This approval was extended by Sask Water 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 salinity 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. Operation of the 

 salinity project continued in 2002 with production of 631 dam of ground water. This was much lower 

 than the 2001 production level of 819 dam . and substantially lower than the average annual production 

 of 880 dam^/year since the project inception in 1990. Production remains below optimal levels due to 

 ongoing mechanical problems in the production wells with only PW 87104 being in service at year's 

 end. An ongoing well rehabilitation program is expected to restore production to the levels achieved in 

 the early 1990's. 



Approximately 65 percent of the total volume pumped came from wells PW87103 and PW87104 which 

 are located on the east side of the river and the remainder was produced from PW90109 and PW90108 

 on the west side of the river.
