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

 dam^/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. 



SaskPower's 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. 



hi 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 2001 with production of 819.4 dam"' of ground water. This was greater than 

 the 2000 production level of 675.9 dam^, but still below 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. An ongoing well rehabilitation program is expected to restore 

 production to the levels achieved in the early 1 990's. 



Approximately 58 percent of the total volume pumped came fi"om wells PW87103 and PW87104 which 

 are located on the east side of the river and the remainder was produced fi-om PW90109 and PW90107 

 on the west side of the river.
