major sockeye-salmon-producing river systems in inner 

 Bristol Bay. The net seaward flow of river runoff water is 

 along the northwest side of the bay, and the apparent net 

 motion of seawater is toward the head of the bay on the 

 southeast side. 



The vertical distribution of salinity shows that the in- 

 ner bay and the lower reaches of the rivers are vertically 



homogeneous. As a result, the circulation pattern in this 

 region does not vary with depth. The motion toward the 

 head of the bay, as pointed out earlier, extends to and 

 perhaps somewhat above the Middle Bluff area in 

 Kvichak Bay. 



The distribution of salinity (Figs. 3-6) and the routes of 

 drift cards (Figs. 9-16) both indicate that waters of rivers
