 3.3.2 Ground-Water Levels 



3.3.2.1 Saskatchewan 



The December 1994 drawdown map for the Hart Coal Seam (figure 3.9) indicates that there was a 

 slight contraction in the 1 -metre drawdown contour In the northwest portion of the area. The 

 apparent expansion of the 1 -metre drawdown in the southwest portion of the area was most likely 

 due to the re-establishment of piezometer 51 OA. There were no significant changes in the 

 drawdown contours of 5 metres or greater. Nine piezometers were deleted from the monitoring 

 network in 1 994. 



The December 1994 drawdown map for the Empress sands (figure 3.10) Indicates that there was a 

 slight overall reduction in both the extent and magnitude of drawdowns from Salinity Control Project 

 pumping. 



This reduction is a reflection of the significant recharge which occurred In 1993 and 1994. The goal 

 of the project is to lower water levels in the Empress sands below the reservoir by 2 to 3 metres. 

 This had been established prior to the significant recharge which started in June 1993. The 

 increased pumping rate in 1993 and 1994 has been able to re-establish a 2-metre drawdown cone 

 around well PW87102. Similar operation of the Salinity Control Project will continue until a two- to 

 three-metre drawdown cone is established again. 



Three piezometers associated with the Salinity Control Project were damaged. Two of these are to 

 be replaced. Two or three new piezometers will also be installed.
