1987a). Be^nning in 1984, the number of fish 

 impinged continued to decline as cooling-water 

 flow remained high. Certainly, the removal of 

 the cofferdam contributed to the reduction of 

 impingement at Unit 2, but impingement levels 



were expected to remain constant instead of con- 

 tinuing to decline. Change in water circulation 

 patterns caused by the start-up of Unit 3 may 

 have contributed to the continued decline in 

 impingement at Unit 2.
