ACKNOWLEDGMENTS 



The writer wishes to acknowledge the fore- 

 sight of William F. Thompson, who formulated 

 basic concepts of ground-water hydrology and 

 interchange of stream and intragravel water 

 in a salmon stream some years ago. He also 

 wishes to express his appreciation to William 

 F. Royce, Robert L. Burgner, and Ted S. Y. 

 Koo of the Fisheries Research Institute, for 

 helpful suggestions in the preparation of this 

 paper.
