Freshwater Inflows of many of our bays have already been reduced 

 or altered through construction of upstream water supply dams. In 

 addition to the obvious effect of increasing salt water intrusion 

 into fresh water systems of the riverine flows, we must also know 

 how the estuarine habitat is beinq limited by this increased salinity 

 due to increased ocean influence and the reduced mass of water in 

 a more brackish condition. The same question might well be framed 

 with any of the many other forms of parameter alteration that have 

 occurred. Temperature increase in critical areas might be extremely 

 important, perhaps far in excess of the actual amount of water being 

 affected, for if a critical area is affected, we might find ourselves 

 with a situation of a "gate" that has been closed and whole areas of 

 a formerly beneficial ecosystem removed from use by desirable 

 organisms. 



Residual Pollutants 



Residual pollutional material such as trace organic compounds and 

 minerals, pesticides, herbicides, heavy metals, etc., are reaching 

 estuarine areas from either surface runoff or riverine incuts. 

 The specific kinds, amounts, and effects of these compounds are
