Van der Kamp and Maathuis (1989) concluded that a lowering of water 

 levels by 1 to 3 metres would be possible. This would roughly correspond 

 to pre-reservoir levels. Figure 32 shows the development of two meter 

 drawdown contours around PW87102, PW87103, and PW90108 and demonstrates 

 that the project has shown a reasonable degree of success. Pumping from 

 PW9010 6 should begin to increase drawdowns on the northwest side of the 

 river. The 1.0 metre drawdown is approximately 1 kilometre north of the 

 International Boundary, while the 0.5 metre drawdown crosses the 

 boundary.
