SaskPower Corporation has applied for an approval to operate the three existing production wells at 



a rate of 360 dam^/year (180 U.S.gpm). The modelling study predicts that after ten years, 

 drawdowns in the range of 1 to 5 metres at the International Boundary would result from production 

 from these wells. Saskatchewan Water Corporation is currently reviewing this allocation request.

Water levels in monitoring wells 8, 9, and 11 fluctuated in response to seasonal changes. Water 

 levels in wells 5-7, 13, 16, 17, 19, and 22 increased in 1994 reflecting higher rates of recharge (figure 

 3.11). The influence of pumping from Salinity Control Project wells was observed in wells 10 and 24.
