Sask Power has assumed the responsibilities for compiling and submitting 

 drawdown maps for the Hart Coal Seam. Figure 30 shows the drawdowns as 

 of December 1990 while, for comparative purposes Figure 31 shows the 1988 

 drawdowns. The one metre drawdown contour has not significantly advanced 

 in the past year, and currently is approximately 1.8 kilometers from the 

 International Boundary. Piezometers south of the border have begun to 

 show drawdown effects of approximately 0.3 metres. This is most likely a 

 function of continued pumping for the supplementary supply. However, 

 some water level decreases may be attributed to a continuation of the 

 drought. These drawdown effects will reguire close monitoring. 



Comparison of Figures 30 and 31 indicates that the drawdown is continuing 

 to expand in a northwesterly direction towards Fife Lake. The one metre 

 drawdown appears to have reached the vicinity of Fife Lake, but the 

 monitoring network is presently inadeguate to accurately delineate the 

 contour. The magnitude of the drawdown in the area of Fife Lake should
