3.3.2.1 Saskatchewan 



In 2003, SaskPower reduced its monitoring network from 180 to about 85 piezometers. Saskatchewan 

 Environment approved this reduction based on modelling studies undertaken by SaskPower. 



The goal of the Salinity Project is to lower ground-water levels in the Empress sands below Morrison 

 Dam two to three metres, which is roughly equivalent to pre-reservoir levels. Production from 1990 to 

 1995 ranged between 900 and 1,100 dam'^/year and consequently the drawdown objectives were 

 achieved in 1995 and 1996. Declining production from 1995 until 2004 resulted in a continual reduction 

 in the cone of depression. By 2003 the drawdown cone of depression was negligible. The drawdown 

 cone increased somewhat in 2004 and 2005 due to the increased production, but is still limited in extent 

 and magnitude. 



Figures 3.14 and 3.15 show hydrographs for Hart Coal seam monitoring wells near the International 

 Boundary. These hydrographs illustrate that there have been no significant changes in water level in the 

 Hart Coal seam near the boundary in the past 10 years.
