bays, there is no need to take pre- 

 ventive action. 



The seasonal timing of floods 

 can have important consequences. The 

 occurrence of a flood when larvae of 

 economically important species are 

 in the zooplankton could signifi- 

 cantly reduce future harvests in 

 the bay by displacing or killing 

 these larvae. At this time the im- 

 portance of the influx of organisms 

 and zooplankton from neighboring 

 bays can not be overstated. Re- 

 cruitment from these bays can assist 

 in re-establishing these economically 

 important species. Thus, it is nec- 

 essary to define the circulation pat- 

 terns between estuaries and to real- 

 ize their interdependence so as not 

 to delude ourselves into relinquish- 

 ing one estuarine area to pollution 

 as though it were an entity unto 

 itself.
