Figure 3.10 illustrates the extent and magnitude of the cone of depression in the Empress Sands as 



a result of the Soil Salinity Project. The pumpage is resulting in drawdowns of approximately 1 metre 

 at the International Boundary in Sections 4, 5, and possibly 3, of Township 1 , Range 26, West of 2. 

 The projected goal for achieving drawdowns in the order of 2 to 3 metres has now been achieved, 

 and therefore future pumping should be relatively stable subject to water levels in Cookson 

 Reservoir 



3.3.2.2 Montana 



During 1992, water levels continued to decline in monitoring wells located in Montana with the 

 exception of wells 2, 8-9, 11, and 21. At the International Boundary, water levels have declined 

 approximately 0.6 metres in wells 5 and 6 and about 1 metre in well 10. Well 10 is responding to 

 pumpage from the Hart coal seam and probably pumpage from Soil Salinity Project wells along the 

 East Poplar River downstream from Morrison Dam. 



Hydrographs of selected wells which monitor water levels in the Hart coal seam are shown in figure 

 3.11.
