Results of the Trinity Bay study.

Studies were conducted on the Trinity Bay estuary in order to gain insight into the possible effects of a general reduction of fresh water into the system. From the data coupled with those found in the literature, it appears that optimum salinity for the Trinity Bay estuarine habitat lies between 10 ppt and 17 ppt with the lower and higher extremes appearing near to and away from the mouth of the river respectively. To maintain this habitat, it was recommended that a mean monthly discharge of 2,000 C.F.S. be maintained during the critical months of March through October when the bays are utilized by important estuarine species.
