 5.3 Groundwater Levels 



5.3.1 Saskatchewan 



Drawdowns for the salinity project are similar to those for the year 1 990. Small changes 

 in pumping patterns resulted in a slight decrease in drawdown on the east side of the 

 river and a slight westward expansion of the cone of depression. 



5.3.2 Montana 



In 1990, two wells were installed to monitor effects of pumping the alluvial aquifers along 

 the East Fork of Poplar River for salinity control. An attempt was made to install wells, 

 one on each side of the East Fork of the Poplar River in the alluvium, but work on well 

 (23) on the east side could not be completed. 



Water levels in well 24 are approximately one metre below the land surface and show a 

 decline of approximately fifteen centimetres for 1991.
