DEDICATION 



During 1983, the NU Environmental Laboratory suffered the tragic 

 loss of Bonde Johnson, the laboratory manager, and Susan Hobbs, a member 

 of the Fish Ecology group. Both Bonde and Susan were keenly aware of 

 the importance of the work being conducted at NUEL. As laboratory 

 manager, Bonde actively supported our efforts to obtain sound scientific 

 data. His interest was reflected in his many suggestions, which 

 frequently improved our programs and the quality of the data. Susan's 

 infectious enthusiasm and genuine concern for the environment in which 

 we all live was a constant source of inspiration for the people around 

 her. 



This report is dedicated to the memories of Bonde and Susan as a lasting 

 tribute to the friendships made and the work accomplished at NUEL. They 

 shall be missed by all who knew them.
