with local rainfall. Stronger nega- 

 tive correlations were observed, how- 

 ever, for salinity with streamflow.

2. Major freshwater incursions phy- 

 sically flush out estuarine zooplank- 

 ton populations and replace them with 

 freshwater species . 



3. Increased salinities even as low 

 as 1.0 ppt to 3.0 ppt results in a 

 rapid return of estuarine species, 

 especially the euryhaline copepod, 

 Acartia tonsa . 



4. Periodic high influxes of fresh- 

 water are potentially important 

 sources of nutrients to the estuarine 

 system. 



5. Concentrated studies at point 

 sources of freshwater inflow to the 

 estuaries to monitor biological, phy- 

 sical and chemical parameters should 

 continue to be conducted to establish 

 the most important variables control- 

 ling estuarine communities in rela- 

 tion to freshwater inflow.
