3.3.2.1.1 Frenchmaii Groundwater Project 



Given the low water levels in Cookson Reservoir throughout the early to mid-1990s, 

 SaskPower undertook an evaluation of the Frenchman (Hell Creek) formation as an additional 

 supplementary supply and subsequently submitted an application for 360 dam'/year from the 

 aquifer . There was some written opposition to the project from local residents and concerns 

 were also submitted by the State of Montana and the United States Geological Survey due to 

 potential drawdowns occurring across the International Boundary. The application is still 

 under consideration. 



3.3.2.2 



Montana 



After an increase in water levels in 1994 due to an excellent recharge year, water levels in 

 Wells 5, 8, 16, 19, 22, and 23 declined in 1995 reflecting a return to normal seasonal 

 fluctuations. Monitoring Wells 6, 7, 9, 11, 13 and 17 fluctuated in response to seasonal 

 changes (Figure 3.13).
